The Win-Win Optimization for the Supply Chain Supernetwork with Electronic Commerce Based on the Variational Inequalities

In this paper, we develop a framework for the modeling, analysis, and computation of solutions to a supply chain supernetwork with electronic commerce. The association processes between the manufacturers and the consumers are accomplished through the Internet. Manufacturers are assumed to produce homogeneous materiality products, faced with the criteria - the maximum profit. And the demand markets can purchase the products from the manufacturers according to their economic status through Internet. Then, logistics department union is the combination of a manufacturer´s order management, inventory, transportation, warehousing, materials handling, and packaging as integrated throughout the supply chain supernetwork. Hereon this base, the optimality conditions for the manufacturers, the logistics department union and the demand markets are established using the variational inequality. Then we describe the win-win situation for the supply chain supernetwork model; get the stationary points for this situation. And an example is illustrated to validate the utility of the model in the last part
