Multi-Commodity Flow and Multi-Period Equilibrium Model of Supply Chain Network with Postponement Strategy
With the constant changes of the market demand trends and modern information technology which greatly influence supply chain operation and management, postponement has been developed to be an important strategy in some of the supply chain processes. This paper studies the multi-period and multi-commodity flow supply chain network equilibrium problem with postponement strategy under a type of supply chain management pattern. Taking the influences of the relationship between orders and inventory management of supply chain into consideration, and employing variational inequality to establish multi-period equilibrium model at each level and network equilibrium model , this paper eventually works out the conditions to make the system achieve equilibrium, and also offers economic interpretation with concrete examples to verify them.
