Research on Food Inventory-Distribution Integrated Optimization for VMI Systems

In this paper, the food inventory-distribution integrated optimization problem on a two-echelon logistics system composed of a single distribution center and many sales points is studied under the conditions of VMI strategy and determinate demand.Considering both inventory cost and distribution cost in logistics system, the author constructs an integrated optimization model to minimize the system cost and puts forward the iterative algorithm to solve the model, so as to get the optimal solution of inventory control and distribution decision-making.At the same time, distribution is divided into TL and LTL to consider in the calculation of the distribution cost.Finally, this paper selects an enterprise logistics system as an example and uses mathematical simulation MATLAB software to solve the problem, which demonstrates that the optimization model and algorithm is effective and reasonable.
