Research On Service Spare Parts Logistics Of Location Inventory Routing Problem Based On Closed-Loop Supply Chain

With the world economy big pattern changes and the development of economy, commercial competition becomes increasingly fierce, some new logistics management means born quietly. At present, the closed-loop supply chain and logistics operation of reverse logistics model is getting more and more attention by people, especially since the1990s, along with the progress of science and technology and the development of economy, the formation of global integration, the traditional supply chain has not been able to meet the needs of their people and green environmental protection request, also cannot save more profit for the supply chain. At the same time, people’s dependence of service and requirements of the quality is also rising so provide good after-sales service for the enterprise, which is an important strategy. As the production enterprise of product modularization production and service of spare parts logistics mode is widely popular. This paper, is discussing from the Angle of the closed-loop supply chain services of spare parts logistics location inventory path problem.First of all, this paper makes a comprehensive introduction and analysis on the concept of the closed-loop supply chain, cause, classification, background and characteristics. The paper discusses the concept and characteristics of closed-loop supply chain and strategic significance. And the positive, reverse, and manufacturing supply chain and integration are introduced; And the closed loop of spare parts logistics supply chain services are analyzed.Secondly, based on this, the location of the service spare parts inventory path problem in supply chain placed closed loop, from the point of view of the global, the problem for spare parts logistics service induction decomposition of positive distribution, reverse recovery, reproduction/remanufacturing and various logistics links problems, and put forward the closed-loop supply chain integration, the main points of the location, inventory, path and related logistics operations.Next, based on the0-1integer programming method, in order to ensure that the logistics service level for the premise, make the target of minimizing the total cost of logistics and supply chain services based on closed loop of spare parts logistics location inventory path problem of model, and using MATLAB software, through the simulated annealing algorithm to solve the model. Through solving the closed-loop supply chain services under the location of spare parts inventory path problem, confirmed that the service with spare parts supply chain operation feasibility of the closed-loop, and provides the guarantee service level and minimize the total cost of cases, service spare parts logistics mode of operation.
