【摘要】：物流运输调度问题的研究是供应链管理中一个重要的课题。循环取货策略作为一项常用的调度模式,不仅可以降低企业的运输成本,而且可以协调生产和运输两个计划,减少库存占用空间,进一步减少企业的仓储成本。在采用循环取货的模式时,需要进一步对车辆路径安排进行优化,但是以前的车辆路径优化很少考虑货物的生产安排和临时堆放场地的限制。本文将研究企业在采用循环取货策略时,考虑各个取货点的不同产品生产速度和成品堆放空间制约条件下,如何安排车辆的取货路径问题。本文根据企业的实际运输情况建立模型,将上述问题简化为带时间窗的车辆路径优化问题,设定了时间窗内存放货物时间的要求；同时优化取货路径,使得在产品允许堆放的时间范围内,可以被取货车辆运走。然后,通过比较相关算法,最终选择了粒子群算法去求解运输路径优化问题。在案例应用中,结合在职公司的实际运输需求情况开展案例研究。通过将原先运输路径方法和运营成本与使用环取货管理模式下,进行路径优化后的成本比较,验证了该方案的成功。从中我们可以看到,运输路径的优化可以使得供应链上的各个方面都收益,最大化的利用了资源、节省了时间、提高了效率。这种管理模式对其他分散式制造企业有借鉴意义。
[Abstract]:The research of logistics transportation scheduling is an important subject in supply chain management. As a commonly used scheduling mode, the cyclic delivery strategy can not only reduce the transportation cost of enterprises, but also coordinate the production and transportation plans, reduce the space occupied by inventory and further reduce the storage cost of enterprises. Further optimization of vehicle routing is needed in the mode of cyclic cargo collection, but the previous vehicle routing optimization seldom considered the production arrangement of goods and the limitation of temporary stacking site. In this paper, we will study how to arrange the routing of vehicles under the conditions of different production speed and stacking space of finished products when enterprises adopt recycling strategy. In this paper, according to the actual transportation situation of the enterprise, the above problem is simplified as the vehicle route optimization problem with time window, and the requirement of the time for storing goods in the time window is set up, and at the same time, the route of picking up goods is optimized. So that the product is allowed to pile up within the time frame, can be removed by the pick-up vehicle. Then, by comparing the correlation algorithm, the particle swarm optimization algorithm is chosen to solve the transportation path optimization problem. In the case application, combined with the actual transportation demand of the company to carry out a case study. By comparing the original transportation route method and operation cost with the cost after route optimization under the mode of using cyclic cargo management, the success of the scheme is verified. We can see that the optimization of transportation path can make all aspects of the supply chain benefit, maximize the use of resources, save time, improve efficiency. This management model has reference significance to other decentralized manufacturing enterprises.
