Research On Supply Chain Model Based On Mixed Integer Programming

With the incremental development of world economic integration and market globalization, and the quick development of information technology, supply chain management (SCM) has been the important management mode for modem enterprises since 1990.The differences in apparent technology advantage among enterprises have been becoming smaller and smaller,and core competitiveness depends mostly on their supply chains. Integration of supply chain activities has become competitive necessity in most industries.In this paper,firstly, the overseas and domestic study situation on SCM is reviewed.Secondly, we study the integrated supply chain-marketing problem in supply chain network composed of single plant,multiple products,multiple periods and multiple distribution centers.An integrated model is proposed using stochastic mixed integer programming approach.Stochastic model solves the problem of demand uncertainty.Meanwhile,the model optimizes production lot size,vehicle schedule and inventory in the system.The numerical example shows the application of the model. The numerical example is solved using Wha's Best!.Outcome indicates that the method is feasible.Thirdly, we study the integrated supply chain-finance model.The aim is the maximum of the rights and interests of the owners. At last,the model can be extended in many aspects.
