【摘要】：近年来,随着电子商务的兴起,我国快递行业取得了飞速的发展。2014年我国快递业务量达140亿件,同比增长52%,已跃居世界第一位。然而在快递业务量爆发式增长的同时,大量快递包装所带来的环境污染、资源浪费等问题也日益突出。快递包装的回收再利用已成为政府、快递企业、消费者的共识,但是快递包装回收的实施过程中仍然存在着缺乏包装回收的渠道、包装没有统一标准、重复利用的纸箱易破损等问题,亟待解决。因此,本文首先根据我国快递包装回收现状,借鉴国外包装逆向物流体系的管理经验,提出构建一个完善的快递包装回收体系,并从回收流程、包装标准化、回收激励机制等方面进行了优化设计,以实现对快递包装的回收再利用；其次根据所设计的快递包装回收体系,分析快递包装逆向物流网络系统并对其进行优化。在逆向物流系统优化中的关键就是解决设施定位、运输路线安排和库存控制问题,而且三者之间也存在着密切的联系,为此本文对快递包装逆向物流网络进行定位—路径安排—库存问题(Location-Routing-Inventory Problem, LRIP)的集成优化与管理,并建立以系统总成本最小的的数学模型,由于LRIP问题属于NP-Hard问题,无法用精确算法进行求解,本文设计了两阶段启发式的改进算法对构建的数学模型进行求解；最后,以大连市某快递企业为例,选取部分快递网点作为快递包装的回收点,收集相关数据进行计算,对快递包装逆向物流网络中各回收点间收集路线安排、回收中转站的选址以及库存控制策略等问题进行了集成优化,研究结果也表明文中设计的模型和求解算法具有可行性和有效性。
[Abstract]:In recent years, with the rise of electronic commerce, China's express delivery industry has made rapid development. In 2014, China's express delivery business reached 14 billion pieces, an increase of 522% compared with the same period of last year, ranking first in the world.However, with the explosive growth of express delivery business, the environmental pollution and resource waste caused by a large number of express packages are also increasingly prominent.The recycling and reuse of express packaging has become a consensus among the government, express delivery enterprises and consumers. However, there is still a lack of channels for packaging recovery in the implementation of express package recycling, and there is no unified standard for packaging.Problems such as easy breakage of recycled cartons are urgently needed to be solved.Therefore, according to the current situation of package recovery in our country and the management experience of foreign packaging reverse logistics system, this paper proposes to construct a perfect package recovery system, and from the recovery process, packaging standardization.In order to realize the recycling and reuse of express package, the incentive mechanism of recycling is optimized. Secondly, the reverse logistics network system of express package is analyzed and optimized according to the package recovery system designed by the paper.In the optimization of reverse logistics system, the key is to solve the problems of facility location, transportation route arrangement and inventory control.In this paper, the integrated optimization and management of location-Routing-Inventory problem (Lipp) are carried out for the reverse logistics network of express packaging, and a mathematical model with the minimum total cost of the system is established. Because the LRIP problem belongs to the NP-Hard problem,This paper designs a two-stage heuristic improved algorithm to solve the mathematical model. Finally, taking a express delivery enterprise in Dalian as an example, some express outlets are selected as the recovery point of express package.Collect the relevant data to calculate, and optimize the collection route arrangement among the collection points in the reverse logistics network of express package, the location of the recovery transfer station and the inventory control strategy, etc.The results also show that the proposed model and algorithm are feasible and effective.
