Model and Algorithm for Computer Spare Parts Logistics Management System

Abstract. How to provide customers with timely and effective logistics and distribution services as well as reduce the production cost of the sales process has become increasingly important for enterprises in recent years. This paper is a study on computer spare parts logistics management information system project. It describes the project background and the composition of the system. Research is carried out on how to handle the distribution model with multiple types of nodes and more complex spare parts logistics. The open-source Mixed Integer Linear Programming (MILP) solver-lp_solve is used to solve the model, and the global optimal solution can be reached by employing branch-and-bound methodology. Finally this paper proposes a heuristic algorithm to meet the business needs and quickly get the approximate result
