Optimization model and algorithm for ordering and logistics distribution of distribution center
This paper studies ordering problem and logistics distribution of the distribution center in the supply chain. From the perspective of supply chain integration, considering inventory capacity constraints of distribution center and vehicle routing constraints, the optimization model of ordering and distribution are proposed firstly and the average total costs are minimized. In the process of logistics distribution, the grouping strategy is considered, and it improves the efficiency of logistics distribution. According to the characteristics of the optimization model, the genetic algorithm is selected to solve the model. A numerical example shows that the algorithm is effective and the model can provide a solution of ordering strategy and logistics distribution with heterogeneous items for the distribution center.
