【摘要】：在经济全球化的推动下，越来越难在劳动力和人力资源上取得成本优势，物流成为第三方利润源。循环取货是一种介于传统运输模式和供应链配送模式结合后的创新供应物流模式。能够适合当下流行的JIT的生产模式，即是定时刻、小批量、多批次的车辆沿循环路线到各供应商处取货的供应物流模式。这种新型的物流模式能够弥补传统运输带来的高成本、低时效性造成的不良影响。本文将以X公司的物流改革为例，在分析了X公司物流现状和现阶段国内外知名工程机械制造业生产和物流活动产生的矛盾冲突后，引出循环取货模式。对循环取货的原理、实施条件、基本流程做了介绍，，具体分析研究X公司物流现状，尝试改变传统的物流模式，运用循环取货的方式改善现有的生产经营与物料供应的矛盾。重点对循环取货的路径规划进行研究，分别考虑了不带时间窗和带时间窗的循环取货路径规划问题。依次运用了扫描法、节约里程法和带时间窗的节约里程法对循环取货路径进行规划与优化，构建了循环取货问题模型，利用MATLAB软件工具对复杂的模型进行求解，得出优化的车辆配给和路径规划结果，分析对比了优化前后的线路方案，明确了各种方案的优缺点。本文研究对循环取货理论具有一定贡献，并且能够提高相关企业经济效益。
[Abstract]:Under the impetus of economic globalization, more and more difficult to obtain cost advantage in labor and human resources, logistics has become the third source of profit. Milkrun is a combination of innovation of supply logistics distribution mode between traditional transportation mode and the supply chain. After suitable for JIT when dirty production mode, which is the fixed moment small volume, multi batch mode, supply logistics vehicles along circulation routes to various suppliers. Pick up the new logistics mode can make up for the high cost of traditional transportation caused by the adverse effects caused by the low efficiency.
This paper will take X company's logistics reform as an example, in the analysis of the conflict of X company logistics present situation and domestic and foreign well-known engineering machinery manufacturing and logistics activities, leads to milkrun mode. The implementation conditions on the principle, milkrun, basic process is introduced, the specific analysis of the current situation of logistics research X the company, try to change the traditional mode of logistics, improve the existing production management and material supply contradiction by using milkrun mode. Focus on the research of path planning of milkrun, are considered without time window and time window milkrun path planning problem. Followed by the use of scanning method, and save mileage method with time window to save mileage method milkrun route planning and optimization, construct milkrun model to solve the complex model using MATLAB software tool to obtain excellent The results of vehicle rationing and path planning are compared and analyzed before and after optimization. The advantages and disadvantages of various schemes are clarified. This study has a certain contribution to the theory of cyclic pickup and can improve the economic benefits of related enterprises.
