    Blockchain-based Framework for Supply Chain Traceability: A Case Example of Textile and Clothing Industry2021In: Computers & industrial engineering, ISSN 0360-8352, E-ISSN 1879-0550Article in journal (Refereed)
    Abstract [en]

    Traceability has emerged as a prime requirement for a multi-tier and multi-site production. It enables visibility and caters to the consumer requirements of transparency and quality assurance. Textile and clothing industry is one such example that requires traceability implementation to address prevailing problems of information asymmetry and low visibility. Customers find it difficult to access product data that can facilitate ethical buying practices or assure product authenticity. Besides, it is challenging for stakeholders to share crucial information in an insecure environment with risk of data manipulations and fear of losing information advantage. In this context, this study investigates and proposes a blockchain-based traceability framework for traceability in multi-tier textile and clothing supply chain. It conceptualizes the interaction of supply chain partners, and related network architecture at the organizational level and smart contract and transaction validation rules at the operational level. To illustrate the application of the proposed framework, the study presents an example of organic cotton supply chain using blockchain with customized smart contract and transaction rules. It finally demonstrates the applicability of the developed blockchain by testing it under two parameters. The proposed system can build a technology-based trust among the supply chain partners, where the distributed ledger can be used to store and authenticate supply chain transactions. Further, the blockchain-based traceability system would provide a unique opportunity, flexibility, and authority to all partners to trace-back their supply network and create transparent and sustainable supply chain.

    A method for measuring and valuing transport time variability in logistics and cost benefit analysis2017In: Research in Transportation Economics, ISSN 0739-8859, E-ISSN 1875-7979, Vol. 66, p. 59-69Article in journal (Refereed)
    Abstract [en]

    The freight transport system is subject to delays and disturbances, which influence investment and planning decisions made by governments and infrastructure authorities. Traditionally relying on Cost Benefit Analysis (CBA) they are dependent on correct and up-to-date input data. So far, little success has been reached in estimating the effects of disturbances for freight. This paper aims to contribute to the understanding of disturbances in freight transport by reviewing and classifying the effects occurring due to transport time variability (TTV) and to suggest a calculation model to estimate the value of transport time variability (VTTV). In order to validate the model and its usability it was successfully tested in a case study for a large Swedish retail company. The effects of delays can be divided into four main types: System Killers, Catastrophic Events, Expected Risks, and Contingencies, of which the last two are relevant for VTTV. The model applies these in a two-step cost function with a fixed and variable part, building on previous studies of VTVV for passenger transport based on the scheduling utility approach. A main theoretical result is that the estimation of VTTV is derived mathematically independently of which measure that is chosen for the quantification of TTV.

    Säkrare transporter av farligt gods – Ett förslag till nollvision: Sammanfattning från ett forskningsprojekt2021Report (Other academic)
    Abstract [sv]

    Säkra transporter av farligt gods på väg och järnväg är en synnerligen komplex aktivitet i skärningen mellan juridik, teknologi, logistik, ekonomi, organisation, och individ. Graden av komplexitet ökar med frågor om styrning, säkerhet, miljöhänsyn, hållbarhet, fysisk planering, och konkurrens. Planering av forskningsarbetet, datainsamling och analys har skett i en tvärvetenskaplig kontext där forskare från juridik, logistik, informatik, och miljövetenskap deltagit. Exempel på frågeställningar som har studerats inom ramen för projektet är säkerhetsrådgivarens roll och funktion, problem och brister i transportkedjan, vilka aktörer som är involverade i transportkedjan och hur trafikpolisen utför sina operativa kontroller av transport av farligt gods. Vidare har projektet resulterat i nya forskningsfrågor att undersöka och analysera i framtiden. Det handlar bl.a. om hur våra urbana miljöer ska kunna utvecklas och möta utmaningar kopplade till transport av farligt gods. Detta presenteras närmare i ”case Älvstaden”. Studierna av regelverken som styr transporter av farligt gods, logistiska begrepp och principer som bidrar till ökad precision avseende en nomenklatur, och transportkedjan som informationsmiljö, utgör exempel som är mer teoretiskt grundade i de olika disciplinerna. På en övergripande nivå är detta ett viktigt komplement till de empiriska avsnitten och en förutsättning för att kunna tydliggöra komplexiteten i projektet. Denna kortare rapport återger viktiga resultat i projektet, och den utgör sammanfattning av en längre slutrapport som publiceras hos MSB hösten 2021. I den längre rapporten, Säkrare transporter av farligt gods genom transparent informationshantering och samverkan, återfinns nulägesbeskrivningar med tillhörande publikationer som utgör ett mer samlat resultat av projektmedlemmarnas ansträngningar. För att nå målbilden om säkra transporter samlas de viktigaste resultaten från projektet i en lista med åtgärdsförslag. Dessa förslag omfattar områden som vi anser har särskilt god potential för utveckling och ett urval av sådana åtgärdsförslag finns med i denna slutrapport.

    Säkrare transporter av farligt gods genom transparent informationshantering och samverkan: Slutrapport från ett forskningsprojekt2021Report (Other academic)
    Abstract [sv]

    Farligt gods kan definieras som de ämnen och föremål som kan orsaka skada på människor, miljö och egendom om de inte hanteras på rätt sätt under transport. I förhållande till den mängd farligt gods som transporteras i Sverige inträffar förhållandevis få allvarliga olyckor. Däremot inträffar en incident med farligt gods nästan varannan dag i Sverige. Syftet med projektet är att bidra till att transporter av farligt gods kan genomföras på ett så säkert, men ändå ändamålsenligt, sätt som möjligt. Utgångspunkten är att identifiera styrkor och svagheter längs transportkedjan för att olyckor med transport av farligt gods ska kunna undvikas. Inom projektet har information och kunskap samlats in direkt från privata och offentliga aktörer i transportkedjan eller med koppling till kedjan. Detta har skett genom intervjuer, möten, fältstudier, studiebesök, workshops och konferenser samt indirekt genom bland annat litteraturgenomgångar, studier av media och regelanalyser med stöd av juridisk metod. Undersökningarna har, förutom denna rapport, resulterat i ett flertal publikationer, såsom exempelvis vetenskapliga artiklar, böcker och konferensbidrag samt olika typer av presentationer. Den kanske viktigaste kunskapsspridningen har dock skett genom en nära dialog med avnämare och genom ett ömsesidigt lärande. I denna rapport återges viktiga resultat från projektet. I kap. 2-7 återfinns en nulägesbeskrivning med tillhörande publikationer som utgör ett samlat resultat av undersökningarna som utförts under projektets gång. Nulägesbeskrivningen omfattar en beskrivning och analys av följande: • transportkedjan vid transport av farligt gods (kap. 2) • transportkedjan som en informationsmiljö (kap. 3) • regelverken rörande transport av farligt gods (kap. 4) • säkerhetsrådgivare för transport av farligt gods (kap. 5) • tillsyn för säkrare transporter av farligt gods (kap. 6) • problem och brister i transportkedjan (kap. 7) Kapitlen utgör ett underlag för att kunna formulera de åtgärdsförslag som presenteras i kap. 8. I det avslutande kap. 9 ges en utblick mot framtidens utmaningar. Det ska poängteras att det inte finns ett enda specifikt problem inom området för transport av farligt gods, utan det föreligger flera olika problem. Dessa problem kan enskilt eller i samverkan med varandra leda till risker som påverkar säkerheten negativt vid transport av farligt gods. Det är därför viktigt att riskerna minimeras, till fördel för ökad säkerhet. Det finns dock inte en enda lösning eftersom området är komplext med många aktörer och omfattande och detaljerade regelverk. Vi presenterar åtta åtgärdsområden som vi menar är särskilt viktiga och introducerar en målbild som består av en nollvision för olyckor, incidenter och tillbud vid transport av farligt gods. Nollvisionen preciseras i kap. 8. De aktuella åtgärdsområdena presenteras i kap. 8 och utgörs av: • Ökad medvetenhet • Ändamålsenliga regelverk • Rätt kompetens • Stärkt säkerhetsrådgivarroll • Informationstillgång • IT-system med samverkansförmåga • Synliggörande av dolt farligt gods • Effektiv tillsyn och kännbara konsekvenser Åtgärdsområdena innehåller en tillhörande problematisering för att sätta området i sitt sammanhang. Varje åtgärdsområde omfattar även en delvision som visar på vad just det området kan bidra med för att nå nollvisionen som framförs i projektet. Vidare ges exempel på konkreta åtgärdsförslag som har kunnat identifieras genom forskningen i projektet. Dessa åtgärdsförslag har särskilt god potential att kunna bidra till säkrare transporter av farligt gods.

    Cargo theft at non-secure parking locations2015In: International Journal of Retail & Distribution Management, ISSN 0959-0552, E-ISSN 1758-6690, Vol. 432, no 1, p. 204-220Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to examine the patterns of reported cargo thefts at

    non-secure parking facilities in Europe, the Middle East, and Africa (EMEA) with respect to stolen

    value, frequency, incident category, and modi operandi.

    Design/methodology/approach – This study is based on a system-theoretical approach that

    emphasizes on a holistic rather than an atomistic view. The research method used in this paper is

    deductive; the analysis is based on data obtained from the incident information service (IIS), a database

    of transport-related crimes from the Transported Asset Protection Association (TAPA) in the EMEA

    region. The results are analysed and discussed within a frame of reference based on supply chain risk

    management (SCRM) and criminology theories.

    Findings – We found that 97 per cent of all attacks during a stop occur at non-secure parking

    locations. Cargo thefts at these locations are more of a volume crime than high-value thefts. Seasonal

    variations were seen in these thefts, and the most common type was an intrusion on weekdays

    during winter.

    Research limitations/implications – This study is limited by the content of and the classifications

    within the TAPA EMEA IIS database.

    Practical implications – This paper is directly relevant to the current EU discussions regarding the

    creation of a large number of secure parking facilities in the region.

    Originality/value – This is one of the first papers in the field of SCRM that utilizes actual crime

    statistics reported by the industry to analyse the occurrence of cargo theft by focusing on the

    non-secure parking aspect in the transport chain.

    Modi operandi for cargo theft in EMEA—A seasonality analysis2015In: Journal of Transportation Security, ISSN 1938-7741, Vol. 8, no 3-4, p. 99-113Article in journal (Refereed)
    Abstract [en]

    This paper identifies patterns and trends in cargo theft by analysing seasonal

    variations (by time of year and time of week) in the relationship between value

    (reported stolen value) and various reported modi operandi. This research is exploratory

    in nature; it is based on theories derived from criminology and logistics as well as

    secondary data related to cargo theft. For practical purposes, the research is geographically

    limited to EMEA; however, the frame of reference is applicable to the analysis of

    antagonistic threats to transport worldwide. Though patterns differ across categories,

    for some modi operandi, seasonal patterns are found across both months of the year and

    days of the week. Despite variations in hot spots, incident categories, stolen and

    endangered objects, and handling methods, the basic theoretical framework is generally

    applicable. This research is limited by the content and classificatory scheme of the TAPA

    EMEA IIS database. However, this is the best available database and it contains anonymous

    reports that are mainly from TAPA member companies that are in the industry itself.

    Theft of pharmaceuticals during transport in Europe2015In: Journal of Transportation Security, ISSN 1938-7741, E-ISSN 1938-775X, Vol. 9, no 1, p. 1-16Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to identify and describe the scale of cargo theft in

    the European pharmaceutical supply chain in 2014. The study is based on a systemtheoretical

    approach which emphasises a holistic rather than atomistic view. The

    research in this paper is deductive and descriptive in its nature and aims to present a

    current description of theft of pharmaceuticals in a European perspective. This paper’s

    hypotheses on cargo theft have been developed from theories of criminology, for

    applicable use, to strengthen the scientific field of logistics. A survey was conducted

    in autumn 2014 whereby the respondents were asked to provide their opinions in

    relation to eleven questions. The survey was sent out to all major players in the

    European pharmaceutical sector – manufacturers and logistics providers specializing

    in pharmaceuticals. The survey captured more or less 80 % of the European pharmaceutical

    manufacturers' market share.We found that the current threats against European

    pharmaceutical transport are small in relative occurrence terms (relatively few attacks on

    a yearly basis compared to other product categories) but on an impact basis thefts of

    pharmaceuticals place as one of the top targets (value wise) for criminals. This research

    supports other sources that the current geographical hot spot for these thefts in Europe is

    in Italy. The top risks are rated as either robbery or theft from vehicle at unsecure parking

    areas. These two different modi operandi can be divided into one frequency related

    threat (theft from unsecure parking) and one impact related risk (robbery).

    Trade wars, embargos and sanctions: Implications for supply chain management2021Conference paper (Refereed)
    Abstract [en]

    Purpose

    The purpose of the study is to explore the logistics and SC effects linked to trade wars, embargos, and sanctions, or even other geopolitical events that effects and alters the current status quo of international trade and business relations. The paper also provides a research agenda for SCM on this basis.

    Design/methodology/approach

    This is a conceptual paper based on a system approach, which emphasizes a holistic view instead of the characteristics of the different parts. The paper revisits macro-economic and geopolitical developments and evaluates their impact on, and implications for supply chains.

    Findings

    The paper frames supply chains within macro-economic and geopolitical events and their development. It shows that causal relationships between acts of trade conflict to an actual and intended change in the trade between actors are weak, paradoxical, and non-linear. Outside of conflicts, changes to the rules and regulations in international business are slow and predictable, allowing for companies and their supply chains to adapt. Trade wars make the changes in trade regulations less predictable but they are also introduced at a much higher pace. This results in higher uncertainty for all involved actors. This also results in a new supply chain systemic behaviour, which is better understood as a complex system instead of the more traditional supply chain view of stable links and nodes.

    Originality/value

    The paper contributes to the understanding of geopolitical developments and their implications for supply chain management and develops a specific research agenda for supply chain management.

    The moderating role of transport chain location in cargo theft risk2020In: The TQM Journal, ISSN 1754-2731, E-ISSN 1754-274X, Vol. 32, no 5, p. 1003-1019Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to explore cargo theft risk and security for different product types at different locations along a transport chain. Design/methodology/approach: This study is based on a system-theoretical approach. The research method is deductive, as the analysis is based on secondary data and results from a questionnaire. The results are analysed based on supply chain risk management (SCRM) theories. Findings: Due to substantial interaction effects, the type of product and transport chain location must be considered to determine the correct level of security. Specifically, the product type is more significant, since the general cargo theft risk is higher. Furthermore, the transport industry has three perspectives on security responses to cargo theft, namely, demanded, needed and actual security, which differ depending on the product type and transport chain location. Research limitations/implications: This database is structured according to the global Transported Asset Protection Association organisational structure, which implies that there are three main databases: Europe, Middle East and Africa, Americas, and Asia-Pacific. Practical implications: This study has both research and practical implications, as it examines security within freight transport from three perspectives, linked to general cargo theft risk and goods owners’ requirements. Originality/value: This study addresses the contemporary SCRM problem of cargo theft using actual crime statistics and the industry understanding of required generic security levels. © 2019, Emerald Publishing Limited.

    Seasonality of incident types in transport crime – Analysis of TAPA statistics2022In: Journal of Transportation Security, ISSN 1938-7741, E-ISSN 1938-775XArticle in journal (Refereed)
    Abstract [en]

    This paper examines weekly and annual seasonality in incident categories to find patterns and trends in transport crime globally, concerning the value of stolen goods, incident frequency and incident category. Secondary data is utilized to analyse a contemporary challenge in logistics and supply chain research, namely theft and robbery of goods during shipment. The research is based on the TAPA global IIS transport-related crime database. Incident frequencies and mean values are analysed primarily with chi-square tests and analyses of variance (ANOVAs). The results are analysed and discussed within a frame of reference consisting of theories from logistics and criminology. The main conclusion is that there is an annual as well as a weekly seasonality of most incident categories, but the patterns vary among incident categories. The results are primarily limited by the content and classification within the TAPA IIS database.

    The relationship between impact and probability in supply chain risk management: a cargo theft example2020In: International Journal of Decision Sciences, Risk and Management, ISSN 1753-7169, E-ISSN 1753-7177, Vol. 9, no 4, p. 241-241Article in journal (Refereed)
    Abstract [en]

    This study analyses the relationship between probability and impact for different combinations of incident and transport chain location type based on supply chain risk management theories. A deductive research method was used via employing data from the transport-related crime database incident information service (IIS). While the total risk may be the same for different probability-impact combinations, different risk management strategies are required. Regressing probability on impact gives an estimated effect of about–0.5, instead of the theoretically expected –1, indicating that an impact reducing strategy may reduce the total cargo theft risk more than a probability-focused strategy. An alternative risk ranking approach was suggested, which emphasises impact risk as more important than probability risk, implying that certain modi operandi are generating higher impact losses. The risk management strategy should therefore focus on reducing the probability for those incident categories

    The use of violence in cargo theft – a supply chain disruption case2018In: Journal of Transportation Security, ISSN 1938-7741, E-ISSN 1938-775XArticle in journal (Refereed)
    Abstract [en]

    This paper examines patterns of reported cargo thefts involving violence in the Europe, Middle East, and Africa region with regard to the value of stolen goods, incident frequency, transport chain location, and incident category. The research method is deductive and is based on analyses of secondary data obtained from the Incident Information Service by the Transported Asset Protection Association. The results are discussed within a frame of reference based on supply chain risk management and supply chain disruption literature. We found that perpetrators who use violence seem to cause greater losses per theft than those who use other types of modus operandi. Further, the most common type of violent cargo theft occurs on Mondays in January when cargo vehicles are robbed on the road and consumer electronics are stolen. In terms of supply chain disruption, violent cargo thefts can be seen as externally-caused disruptions, which can indirectly cause major problems for the supply chain.

    THEFT OF GOODS IN PORTS A review of TAPA EMEA IIS statistics2018Report (Other academic)
    Abstract [en]

    This report examines patterns of reported cargo thefts at maritime transport facilities in Europe, the Middle East, and Africa (EMEA) with respect to frequency, incident category, modus operandi, and targeted product category. The analysis is based on data obtained from the Incident Information Service (IIS), a database of transport-related crimes from the Transported Asset Protection Association (TAPA) in the EMEA region. The results are analysed and discussed within a frame of reference based on supply chain risk management and criminology theories. We find that maritime transport facilities constitute a rare target location for cargo thieves, as only 102 of more than 24,500 incidents (0.4%) in the IIS database occur there. Nevertheless, some conclusions can be made. First, there seems to be seasonality in day of the week, but probably not in month of the year. Second, violent and fraudulent modi operandi of theft at maritime transport facilities are about as common as in the whole data set. Thus, it could be conjectured that the impact from violent and fraudulent incidents is several times higher than the most common types of incident category or modus operandi, although this is unsupported in this study. The product categories signal that there is big variation in value in stolen goods. Third, it is possible that potential perpetrators consider security levels at maritime transport facilities to be higher, leading to fewer theft attempts. This study is limited by the content of and classifications within the TAPA EMEA IIS database.

    Demand Chain Management: The evolution2011In: ORiON: The Journal of ORSSA, ISSN 0529-191X, Vol. 27, no 1, p. 45-81Article in journal (Refereed)
    Abstract [en]

    The concepts of Supply Chain Management (SCM) and Demand Chain Management (DCM) are among the new and debated topics concerning logistics in the literature. The question considered in this paper is: \Are these concepts needed or will they just add to the confusion?" Lasting business concepts have always evolved in close interaction between business and academia. Di erent approaches start out in business and they are then, more or less simultaneously, aligned, integrated, systemised and structured in academia. In this way a terminology (or language) is provided that helps in further di usion of the concepts. There is a lack of consensus on the de nition of the concept of SCM. This may be one of the major reasons for the difficulty in advancing the science and measuring the results of implementation in business. Relationships in SCM span from rather loose coalitions to highly structured virtual network integrations. DCM is a highly organised chain in which the key is mutual interdependence and partnership. The purpose is to create a distinctive competence for the chain as a whole that helps to identify and satisfy customer needs and wishes. The classical research concerning vertical marketing systems is very helpful in systemising the rather unstructured discussions in current SCM research. The trend lies in increasing competition between channels rather than between companies, which in turn leads to the creation of channels with a high degree of partnership and mutual interdependence between members. These types of channels are known as organised vertical marketing systems in the classic marketing channel research. The behaviour in these types of channels, as well as the formal and informal structures, roles in the network, power and dependence relations, etc. are well covered topics in the literature. The concept of vertical marketing systems lies behind the de nition of demand chains and demand chain management proposed in this paper. A demand chain may be de ned as an integrated and aligned chain built on partnership and mutual interdependence aiming at the creation of a unique competence to identify and satisfy customer perceived value, while demand chain management may be de ned as the e ort to create, retain and continuously develop a dynamically aligned demand chain.

    Implementering av PV-system på Trafikverkets teknikhus2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Solar cell technology has been around for a long time and has with continuous development grown to become a viable alternative for power supply. The advantage of solar panels comes with the possibilities for installations on surfaces such as facades and roofs.

    Västlänken is a large ongoing project in Gothenburg, the project includes the construction of new train stations and the construction of a new railway. This includes the establishment of new signal boxes along the railway. In conjunction with this, Sweco Sweden has raised the question of how to best utilize the roof of these signal boxes.

    The purpose of this thesis is, in cooperation with Sweco Sweden, to investigate the potential output power that can be generated by a photovoltaic system once installed on the signal boxes located in Gothenburg, whether installation of a PV system is possible with the existing equipment in a signal box and how much of the equipment in the signal box that can be powered by the PV-system.

    For the calculation of potential output power from PV-systems, a simulation program designed by Energiforsk AB was used. Regarding the installation options a direct contact with the company that supplies rectiverters to the Swedish Transport Administration was established.

    The results shows that the output power of PV-systems depends on the installation area and the efficiency of the photovoltaic modules. The output power varies from 0.10 kW at the lowest efficiency and the smallest installation area to 1,62 kW at the highest efficiency and largest installation area. Installation of a PV-system is not feasible with the existing equipment in the signal boxes as additional modules and solar chargers are needed for a working system. With the result, the load for the uninterruptible power and the output power from the PV system could be compared for Scenario 1 and Scenario 2, as the load was known for just these two. The part of the load that can be met by the PV-system was calculated to be 1,6 % ̶ 10,1 % for Scenario 1 and 2,3 % ̶ 18,2 % for Scenario 2

    Optimering av orderkvantiteter: En fältstudie på Boråstapeter och Borås Tapetfabrik2023Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis was written in collaboration with the holding company Embellence Group, which has Boråstapeter and Borås Tapetfabrik in its brand portfolio. Warehousing and production are centralized in Borås, and the companies are located in the same building.

    The case companies have a model for determining order quantities that was developed by a consultant where the assumptions of the model are old and therefore confidence is considered low. Currently, the employees work with this method as an aid but often rely on experience instead.

    The purpose of the work is to investigate whether the standard EOK model can be applied to manufacturing companies with a large number of items with a short product life cycle. To investigate this, economic order quantities will be produced for the case company. These quantities will then be compared to the case company's current method of determining order quantities. The primary data used during the report's workflow originates from internal systems in the form of Excel sheets and Qlik.

    In order to compare the models, the total cost of each model was compared. It was discovered that when calculating products with a short life cycle, the traditional total cost formula, as linked to the EOK model, gives a misleading result. Therefore, the formula was adjusted to accommodate short life cycle items. The result shows that the developed EOK model gives a reduction in total cost of 23.3% compared to the case company's current model. However, this generates an increase in average inventory by 93.1%.

    In conclusion, the results show that the EOK model can be applied to items with a short life cycle. It is especially useful for companies that have little or no experience with quantitative models for determining order quantities.

    Spänning i offentlig upphandling: Om användande av ett strategiverktyg2022Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Tension in Public Procurement - The usage of a strategy tool: Public procurement is about public purchases, but also about sale of goods and services to the public sector. In research, public procurement is usually analyzed from a market or a transactional perspective. In contrast, this study uses a strategy-as-practice lens that focuses on the micro activities when public procurement is used as a strategy tool. Both buyers and sellers use public procurement, why public procurement as a strategy tool has potential to assist in their shared strategy work. However, if and how buyers and sellers participate in each other’s strategy work when using public procurement is unclear. The purpose of this thesis is to explore public procurement as a strategy tool and its use when buyers and sellers construct strategies. This is done by focusing on strategic work when buyers and sellers participate in public procurement. A qualitative and case-orientated approach were used to generate the empirical material, which included interviews, shadowing and documents. This study shows how public procurement as a strategy tool helps its users in their strategy work. When the tool was used, its content and the characteristics of the actor, but also practice, guided the strategy work. Three different hierarchal levels of practice were identified, why the ability to guide was determined by the level of detail and the scope of the practice. When constructing strategies, public procurement as a strategy tool emphasized managing information and strategy production. As a result, collecting information, identifying and sorting factors, were the core activities of strategic work. Strategy production was about managing positions and strategic factors. Three categories of factors were identified. Buyers and sellers did participate in each other's activities when constructing strategies, if they were given the opportunity and if they had something to gain from it. The parties' motives and characteristics, but also their perceived relational closeness, determined the design of the interaction and work. For practitioners, the use of public procurement as a strategy tool can contribute to align and make strategic work visible in relation to what is of strategic value.

    Total productive maintenance in support processes: an enablerfor operation excellence2015In: Total Quality Management and Business Excellence, ISSN 1478-3363, E-ISSN 1478-3371, Vol. 26, no 10, p. 1042-1055Article in journal (Refereed)
    Abstract [en]

    In order to stay competitive in today’s marketplace, it is vital to reduce activities that do

    not create value. Lean production has in the last decade been seen as a philosophy to

    reduce non-value time. The office environment often presents a major improvement

    opportunity to reduce non-value time. Lean contributes positively to business

    performance applied in a manufacturing context and is also suggested to do the

    same in a service context. The purpose of the paper is to analyse and determine how

    total productive maintenance (TPM) can be applied within the support process and

    to identify effects from an employee and business perspective. A case study has

    been performed and a qualitative research approach was selected. Empirical data

    were gathered by using semi-structured interviews at one case company, but from

    several teams that had applied TPM. The result was then used as an inductive

    approach to explore how TPM can be applied in a support process. To implement

    and apply TPM within an office context, it should be structured in three steps

    (i) define, (ii) implement and (iii) sustain. TPM should be conducted as a part of the

    ordinary day-to-day work. The planning and discussions connected to TPM can be

    included in regular daily departmental ‘stand-up meetings’ involving everybody. The

    work with 5S and maintenance should also be a part of the TPM structure,

    connecting it as a system and not as an isolated activity. TPM can create value from

    both a business and an employee perspective. In the employee perspective, TPM

    reduces the risk of missing/forgetting areas of responsibility and creates more

    involvement. In the business perspective, objectives such as cost and quality are

    improved, but TPM also enables the reduction of waste.

    Physical planning of transport of dangerous goods in urban context as information environment2021Conference paper (Other academic)
    Abstract [en]

    The purpose of this research in progress is to explore the process of physical planning related to transport of dangerous goods in the City of Gothenburg (CoG) in Sweden. We have identified actors involved, some of their conflicts of interest, and challenges discernable in the planning process and in external yet related activities. Such activities are transportation of dangerous goods itself, and its supervisory control. Qualitative data in terms of written documentation from the detailed plan for transport of dangerous goods in CoG, and transcriptions of interviews have been analyzed. The ontology of the planning process, in terms of internal and external actors, activities, documentation, including legal frameworks, and issues such as access to information, information sharing, and information quality, indicate that the process can be seen as an information environment (Magoulas and Pessi, 1998; Hugosson, Magoulas, and Pessi, 2011). In the next step, the authors intend to expand the research work, and to conceptualize the planning process as an information environment. Stimulated by the idea of possible similarities between the planning process and large architectural design projects, the information environment is planned to be studied as form, context, and temporality (Boland, et al., 2008 and 2020). The research relates to the zero vision in traffic and a safer society (Trafikutskottet, 1998), strategy for research and development - Investing in knowledge for a safer society (MSB 2019), SDG 11 Sustainable cities and communities, and to the Sendai Framework for Disaster Risk Reduction 2015-2030. This paper reports on research executed within the transdisciplinary research project Transparent information management and collaboration for increased safety in the transport of dangerous goods (TISS, 2016-2021).

    En förstudie om utmaningar och risker med transporter av farligt gods i urban miljö: Case: riskområde Älvstaden i Göteborg2020Report (Other academic)
    Abstract [en]

    Forskarna i det planerade projektet RADAR har genomfört den förstudie som redovisas här. Den visar på behov av ny kunskap om transporter av farligt gods i urban miljö. En projektansökan med Älvstaden som case är under utveckling. RADAR står för behov av ny kunskap och detektering av utmaningar och risker med transporter av farligt gods i urban miljö. Internationell forskning visar att transportolyckor i urban miljö orsakar betydande materiella skador, utsläpp av miljöfarliga ämnen, och dessvärre dödsfall (Olsson et al, 2016). Transporter av farligt gods har inte genererat några stora olyckor i Sverige (Trafikverket, 2014). Ändå inträffade 296 olyckor under perioden 2007-2012 (MSB 2014). I urban miljö ökar riskerna i och med vägnätets närhet till bostäder och verksamheter och Älvstaden i Göteborg är ett område som utgör ett tydligt exempel på detta med betydande flöden av människor och farligt gods på en liten yta. Projektet RADAR syftar till att klargöra och analytiskt beskriva risker och utmaningar med transport av farligt gods i urban miljö, och att undersöka och analysera den fysiska planeringens styrning, praktik och konflikter. Det övergripande syftet med RADAR är att bidra till nollvisionen i trafiken och ett säkrare samhälle genom att tillföra relevant kunskap som kan användas av de aktörer som har som ansvar att skydda liv, hälsa, egendom och miljö. RADAR relaterar till MSB:s strategi för forskning och utveckling – Investering i kunskap för ett säkrare samhälle, SDG 11 Hållbara städer och samhällen, och till Sendai Framework for Disaster Risk Reduction 2015-2030.

    Elektrifierade tunga fordon och deras elnätspåverkan2023Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Large transportation buyers show a great interest in using electric trucks to reduce carbondioxide emissions and promote a cleaner environment. This entails an increased consumption of electrical energy, which requires the expansion of electrical grids to handle the increased load. Borås Elnät is responsible for the electricity distribution in central Borås and surrounding areas and wants to investigate how the expansion of the electrical grid can be affected by an increased load from electric heavy vehicles. The purpose of this project report is to identify future charging needs, the impact on the electrical grid, and possible measures.

    The method consisted of three parts to obtain the results. First, the current situation regarding heavy vehicles in Viared was examined, then the current situation for electric trucks, and finally whether the existing electrical grid can handle the potential additional load from electric trucks. Three future scenarios were studied to determine the potential load. These scenarios were based on five, ten, and twenty years into the future. Information was gathered through meetings with companies and dialogues with industry stakeholders, as well as studying existing research and literature. An estimated share of electric vehicles in the vehicle fleet was determined using available information. This information was used to develop a general picture of the future of electric vehicles in Viared.

    The results indicate an increase in electric vehicles for all three scenarios, where the proportion of electric vehicles in the vehicle fleet increases over time. This may impact the electrical grid in Viared, as the highest expected current that can occur exceeds what the current cables can handle. The peak power that can occur at the transformer station is also reaching levels that may indicate the need for action.

    Competitive manufacturing for reshoring textile and clothing supply chains to high-cost environment – A delphi approach2017In: Data Driven Supply Chains / [ed] K. S. Pawar; A. Potter and A. Lisec, Nottingham: Centre for Concurrent Enterprise, Nottingham University Business School, 2017, p. 70-80Conference paper (Refereed)
    Abstract [en]

    Existing knowledge of reshoring, enabled largely by competitive manufacturing (CM) strategies in high-cost locations, is limited particularly in context to labour-intensive industries, like textile and clothing (T&C). The purpose of the paper is to identify and prioritize various CM-related supply chain factors that can enable reshoring of T&C to high-cost area. Following a systematic literature review, a multiple round Delphi study is conducted with T&C manufacturers in Sweden to seek practitioners’ perspective. While there is high consensus on the success factors, flexibility to meet short lead times, high product/service quality, and product/service customization; low degree of agreement is reached for the perceived challenges. Some out of literature debates emerged in terms of challenges related to CM in high-cost area, regarding increased fixed costs of production, rise in inventory level due to high product variety requirement, and low skill level against access to skills. Along with the decisive knowledge on the CM-related success factors for reshored supply chains, the Delphi study offers an interesting practitioners’ perspective from a labour-intensive sector like T&C.

    Maritime security guidelines: a study of Swedish ports’ perceived barriers to compliance2020In: Maritime Policy & Management, ISSN 0308-8839, E-ISSN 1464-5254, Vol. 47, no 3, p. 388-401Article in journal (Refereed)
    Abstract [en]

    Due to the constant risk of piracy and terrorist attacks which cause disturbances within international shipping of goods, barriers to the adoption of maritime security guidelines (MSGs) at European ports have become prevalent. In this paper, a conceptual framework was created to explore the perceived barriers that prevent compliance with MSGs. To verify the conceptual framework, empirical data were collected using a mixed-methods approach, which was comprised of interviews with national experts and a survey of 47% of Swedish ports involved in the shipping of goods. According to the presented framework, the perceived barriers of Swedish ports to compliance with MSGs were linked to collaborations within the Swedish Maritime Security stakeholder network, available resources and educational knowledge about security culture. In addition, the perceived barriers of smaller ports were linked to the adaptation to MSGs at different levels and the absence of specific tools of maritime security management. Due to an increased interest in international shipping of goods, this paper is currently one of few that addresses the barriers to compliance with MSGs. Moreover, the paper presents a general conceptual framework, novel managerial implications and recommendations for future research.

    Traits and Transports: The Effects of Personality on the Choice of Urban Transport Modes2022In: Applied Sciences, E-ISSN 2076-3417, Vol. 12, no 3Article in journal (Refereed)
    Abstract [en]

    We examine the influence of personality on car driving, usage of public transport and cycling. Personality is measured through the Big Five personality traits (i.e., Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism) and Environmental personality. Data were collected through a Web-based panel of adult citizen in the city of Gothenburg, Sweden (N = 1068). Age, gender, income, children at home and residential area were used as control variables. Car driving is influenced by low degree of Openness, high degree of Conscientiousness, and low degree of Environmental personality. Usage of public transport is influenced by low degree of Conscientiousness, high degree of Agreeableness, and high degree of Environmental personality. Cycling is foremost influenced by a high degree of Environmental personality.

    Dynamic capabilities in the used clothing supply chain2017In: Data Driven Supply Chains / [ed] K.S. Pawar, A. Potter and A. Lisec, Nottingham, UK, 2017, p. 730-737Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to identify the dynamic capabilities present - and the ones missing - in used clothing supply chains. Such capabilities ensure ability to cope with the rapidly changing conditions in the used clothing supply chain, by creating, modifying and renewing the existing resource base. Particular empirical focus in the paper is given to fashion retailers and charities operating on the Swedish market. Based on the dynamic capabilities classes of sensing, seizing and reconfiguring, empirical data exemplify contemporary dynamic capabilities present among these actors. Theory on dynamic capabilities has to a very limited extent been applied in a reverse supply chain setting. The used clothing supply chain offers an interesting case for the exploration of the dynamic capabilities needed in such a reverse supply chain environment.

    Manufacturing Decisions and A Multi-Tier Supply Location Decision-Support Model for Enhancing Sustainability in Textile and Clothing Supply Chains2020Doctoral thesis, monograph (Other academic)
    Abstract [en]

    A recent trend towards sustainability has led to increases in various sustainable practices, but sustainability has still not been fully implemented into manufacturing and supply location decisions. A fragmented product supply chain, which has various locations and multi-tier suppliers, leads to difficulties in traceability to ensure the supply chain has business, environmental, and social/socio-economic sustainability, known as the triple bottom line (TBL).

    Thus, this thesis aims to reveal which manufacturing decisions and location configurations better contribute to TBL, as well as to develop a location decision-support model for designing or evaluating multi-tier supply chains with objective measurements and TBL factor considerations. Mixed methods are employed, including systematic literature reviews, semi-structured interviews, and supply chain simulations for the model formulation and its viscose t-shirt application. The thesis highlights that TBL benefits of proximity and distant manufacturing are location-dependent with their sources from spatial, cultural, ethnic, and linguistic proximity as well as country-, supplier-, and firm-specific. Spatial proximity benefits can be from proximity manufacturing to markets, materials suppliers, and headquarters as well as proximity between headquarters and market.

    The propose model has the potential to reveal the lowest or optimized cost and carbon dioxide equivalent (CO2e) SCs. The model is capable of revealing important factors and possible risks from future local and global disruptions, benefiting long-term supply chain planning. The model differentiates itself from the others by incorporating TBL from not only manufacturing and logistics activities but also sustainability assurance activities performed by suppliers and focal firms. The model potentially helps enhance TBL sustainability and supply chain visibility. This thesis has theoretical contributions to location theories, manufacturing decisions, cost and CO2e computational models, and sustainable multi-tier supply chain management.

    Clean to be Lean: Implementering av Lean Managment hos kurir- och fraktbolag2023Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis focuses on the freight terminal that belongs to the courier and freight company FedEx Corporation. The freight terminal is located in Landvetter, Sweden. There are some deficiencies and problems in the terminal, and some of these concern how the packagehandling process is structured and how related work activities are performed. The flow in the process is unbalanced, which in turn leads to several consequences such as bottlenecks and waste of time and energy. Hence, the goal of this thesis is to identify opportunities for improvement that can streamline the freight terminal's package handling process. The thesis investigates which improvement tools and methods within Lean management can streamline the work processes in courier and freight companies. To increase the understanding of the current state of the process and its problems, two typs of interviews, several observations, and a survey have been conducted. The qualitative and quantitative data were collected and analyzed to find patterns and trends of the problem. It was concluded that the biggest problems were unnecessary transports, unbalanced workload, bottlenecks, cluttered work stations, high variation in work methods and low rotation between the work stations. Several suggestions for improvement have been presented to reduce or eliminate the above mentioned deficiencies and problems that occur today in the package handling process. The improvement proposals developed in this study are a changed layout for the work stations at the conveyor belt, work station rotation, 5S methodology implementation, and standardized work methods.

    Complexity in transportation and logistics systems: A conceptual approach to modelling and analysis2001Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The basis for the thesis is to assess the usefulness of describing and analysing transportation and logistics systems as being complex systems. The reason and assumption being that in the future more integrated and sophisticated systems and solutions will be demanded. The requirements of the future will also be the requirements of a sustainable society and this also requires higher sophistication in that industry and consumers demand faster and cheaper solutions, but with less environmental impact. The ultimate goal is to use complexity to meet the demand for more sophisticated approaches, models and methods both to better understand these systems and to be able to manage and control them in the most efficient way. In this thesis the concept of complexity is applied to the context of transportation and logistics system in order to better understand the characteristics of these systems. It is an unorthodox method within the research area of transportation and logistics, but it is argued that the concept of complexity provides a valid and valuable model for the analysis of transportation and logistics systems. Complexity is throughout the thesis treated as an important aspect of transportation and logistics systems, and is as a concept used to describe, analyse and model transportation and logistics systems and their properties. The concept of complexity as well as other related concepts are analysed and a conceptual model of transportation and logistics systems' complexity is developed. This model describes the complexity of transportation and logistics systems as residing primarily within three core properties: the network, the process and the stakeholder properties. These properties in their turn are influenced by other extended properties such as variety, connectivity, cognition etc. Three different perspectives; the network, the process and the stakeholder perspectives are used to describe and analyse the transportation and logistics systems. The network perspective focuses primarily on the structure of the transportation and logistics systems, while the process perspective focuses on the activities and dynamics and the stakeholder perspective focuses on the perceptions, represented by the different stakeholders. Four empirical studies are used as a base for the analysis and these four studies are representative for four different aspects of transportation and logistics systems; terminals, supply chains, distribution channels and the transportation of passengers. A measure of transportation and logistics' systems complexity is also develop and applied to these different systems. These studies provide an empirical basis for the research problem studied as well as a validation of the usefulness of the conceptual model of complexity and the proposed measure.
