【摘要】：近年来随着新一代家电产品不断更新换代地出现,家电的寿命周期越来越短,目前我国废旧家电已经进入新一轮的报废高峰期。报废的废旧家电一般都含有大量的金属材料,对于当今资源日渐枯竭的社会,废旧家电的回收不仅能够实现资源的重复利用,为企业带来经济效益,而且还能达到对环境和生态保护的目的。废旧家电逆向物流的回收已成为目前我国物流发展的一个新领域。本文以废旧家电逆向物流为研究对象,主要研究了废旧家电逆向物流的回收体系的构建和路径优化两方面内容。本论文主要包括以下内容:(1)对逆向物流、废旧家电逆向物流的相关理论进行研究,并指出我国废旧家电逆向物流的运作模式和发展障碍。(2)构建了基于回收网络信息平台的废旧家电回收体系,利用回收网络信息平台实时更新信息的功能,加强了回收中心和回收点的沟通和联系,减少逆向物流的分散性、多样性和不确定性。建立了一个闭环的废旧家电回收体系,实现了对废旧家电的充分回收利用和生态环境保护。(3)建立了一个基于成本的确定性废旧家电车辆路径优化模型。该模型为确定性模型。它所研究的是一种回收客户点的位置已知,回收量确定,回收中心在满足一些列约束条件下,指派车辆进行回收并确定每辆车的行驶路线,从而完成所有的回收任务,并使运行成本最低的模型。针对该模型,我们选用了蚁群算法进行求解。并对蚁群算法中出现的收敛速度慢、容易陷入局部最优解的问题,进行算法改进。最后通过一个具体的实例验证了该算法的有效性。
[Abstract]:In recent years, with the emergence of a new generation of household appliances, the life cycle of household appliances is getting shorter and shorter. Scrap household appliances generally contain a large number of metal materials. In today's society where resources are increasingly exhausted, recycling of waste appliances can not only realize the reuse of resources, but also bring economic benefits to enterprises. And also can achieve the purpose of environmental and ecological protection. Recycling of waste appliances reverse logistics has become a new field of logistics development in China. In this paper, the reverse logistics of waste home appliances as the research object, mainly studied the recycling system of waste appliances reverse logistics and path optimization two aspects. The main contents of this thesis are as follows: (1) the related theories of reverse logistics and waste appliances reverse logistics are studied. It also points out the operation mode and development obstacle of the reverse logistics of waste home appliances in our country. (2) A recycling system of waste appliances based on the network information platform is constructed, and the function of updating the information in real time by using the recycling network information platform is put forward. The communication between recycling center and recovery point is strengthened, and the dispersion, diversity and uncertainty of reverse logistics are reduced. A closed-loop recycling system of waste household appliances is established to realize the full recycling and ecological environment protection of used household appliances. (3) A deterministic path optimization model of waste household appliances vehicles based on cost is established. The model is deterministic. What it studies is that the location of a recovery customer point is known, the recovery amount is determined, and the recycling center, meeting some constraints, assigns the vehicle to recycle and determines the route of each vehicle, thus completing all the recycling tasks. And make the model with the lowest running cost. For this model, we choose ant colony algorithm to solve the problem. The algorithm is improved for the problem that the convergence rate of ant colony algorithm is slow and it is easy to fall into the local optimal solution. Finally, a concrete example is given to verify the effectiveness of the algorithm.
