Resource sharing (RS) is an important method in inter-organizational supply chain collaboration (SCC). However, it is still an under-explored area in research of SCC compared to other subjects (e.g. coordinating contract and information sharing). The aim of this paper is to examine the feasibility of applying RS model in the manufacturing stage of garment supply chain and to determine the suitable type of garment for RS in production. Eight scenarios of RS were designed. Discrete-event simulation was used for running experiment of each scenario. The comparison of different scenarios shows that garment manufacturers could get great benefits by applying RS model.
