【摘要】：随着我国城市医疗化的发展,医疗废弃物数量也再不断增长,加上人们目前对环境保护及废弃物处理问题的意识的不断加强,城市医疗废弃物的处理成为目前关注的焦点问题之一,但我国城市医疗废弃物逆向物流的发展与发达国家相比还处于初级发展阶段。为了避免医疗废弃物中有价值资源的浪费,同时做到保护环境及保障人民群众的健康,建立一个规范的、系统性的和高效率的城市医疗废弃物逆向物流网络就显得尤为重要。本文将逆向物流网络结构分为两大类,并可提出根据不同的逆向物流处理方法,选择不同的逆向物流网络结构。以城市的医疗废弃物逆向物流为着手点,以循环经济理论和逆向物流理论为指导,采用定性和定量的方式对城市医疗废弃物逆向物流的网络规划进行了研究。总结了前人关于医疗废弃物的分类、回收网络及处理方式,结合医疗废弃物自身的特点,重点考虑到了医疗废弃物逆向物流相较于传统废弃物回收中存在的特殊问题,包括:危险性废弃物回收处理问题和医疗废弃物存放时间长短对环境污染问题;建立了城市医疗废弃物4层结构式逆向物流网络:回收层、临时处理层、综合处理层和处置层。并在此基础上建立了一个以环境污染最小化、企业利益最大化为目标的非线性网络规划模型,此模型的特点是考虑了医疗废弃物存放时间对环境成本的影响,并考虑了医疗废弃物根据危险程度去分级处理。利用LINGO11.0软件及其自带的全局搜索算法对模型进行求解分析。并以西安市为例进行案例分析,得出目前西安市医疗废弃物逆向物流网络设施的网络选址策略和路径优化策略。
[Abstract]:With the development of medical treatment in cities in China, the amount of medical waste is increasing again, and people's awareness of environmental protection and waste disposal is increasing. The treatment of urban medical waste has become one of the focus issues at present, but the development of reverse logistics of urban medical waste in China is still in the primary stage compared with the developed countries. In order to avoid the waste of valuable resources in the medical waste and to protect the environment and the health of the people, it is particularly important to establish a standard, systematic and efficient reverse logistics network of urban medical waste. In this paper, reverse logistics network structure can be divided into two categories, and different reverse logistics network structure can be selected according to different reverse logistics processing methods. Taking the reverse logistics of medical waste as the starting point and the theory of circular economy and reverse logistics as the guidance, this paper studies the network planning of the reverse logistics of urban medical waste in the way of qualitative and quantitative. This paper summarizes the former medical waste classification, recovery network and treatment methods, combined with the characteristics of medical waste itself, focusing on the medical waste reverse logistics compared with the traditional waste recovery of the special problems, It includes: the problem of hazardous waste recovery and disposal and the problem of environmental pollution caused by the length of storage time of medical waste, and the establishment of a four-layer reverse logistics network of municipal medical waste: recovery layer, temporary treatment layer, comprehensive treatment layer and disposal layer. On this basis, a nonlinear network planning model with the aim of minimizing environmental pollution and maximizing the benefits of enterprises is established. The characteristics of this model are that the influence of medical waste storage time on environmental cost is considered. The medical waste is classified according to the degree of danger. LINGO11.0 software and its own global search algorithm are used to solve the model. Taking Xi'an as an example, the paper concludes the network location strategy and path optimization strategy of medical waste reverse logistics network facilities in Xi'an.
