Research on Supply Chain Inventory Planning with Time-Space Network Under E-Commerce Environment

The problem of multi-period inventory planning in the three layers supply chain composed of multi-manufacturers, multi-retailers and multi-consumers under e-Commerce environment is studied, in which the demand is equal with the supply. The interactive relation of the order time and the transportation space is taken into account. The time-space network is introduced to describe this problem, by which the mathematical model for inventory planning that make the supply chain get the smallest cost is established. Finally, a numerical example is analyzed to prove the rationality of this model, which confirms that the model can provide the best supply chain inventory planning under e-commerce environment.
