【摘要】：进入21世纪以来,我国社会经济规模和水平都有了长足的发展,大量高新科学技术被广泛运用于生产生活领域,医学技术和水平也因此有了较大的提高。在经济发展的同时,各项社会事业投入也逐年增多,特别在医疗卫生方面,各项指标增长较大,各级医疗机构数目、各类卫生机构床位张数等逐年递增,与此同时,农村医疗卫生条件也显著改善,新的医疗设备和治疗技术相继应用于疾病治疗过程,每年新增的医疗废弃物数量不断上升,种类变化较大。辽宁省原有的医疗废弃物处理逆向物流系统也需相应改变,以全面覆盖省内新增医疗废弃物,避免因处理不当导致的医疗废弃物流失,减少对当地居民和病人生命安全和身体健康所造成的威胁。针对新形势下的医疗废弃物处理需求,论文对其处理流程和运行机制做了研究,提出了了区域化处理逆向物流网络拓扑结构,在此基础上论文对辽宁省医疗废弃物区域化处理逆向物流网络进行优化,对逆向物流理论做深入的分析,丰富和拓展了逆向物流理论的应用领域和研究范围。根据目前辽宁省医疗废弃物处理现状,论文深入分析了各市医疗废弃物产量不同、地理位置分布情况等相关特点,充分考虑了与其相关的约束和限制,建立了医疗废弃物处置企业区域化布局整数规划模型,运用现代优化方法和技术,结合现代启发式算法,设计了改进的遗传算法对模型进行求解,最后通过实例求解验证了模型和算法的有效性。优化后的区域化医疗废弃物处理逆向物流网络能有效的解决辽宁省医疗废弃物处理问题,降低医疗废弃物的处理成本,形成规模效应,提高处理能力和效率,避免资源浪费。优化后的医疗废弃物区域化处理模式更有利于相关政府主管部门对其处理过程进行监管,也为相关政策法规制定提供参考和建议。
[Abstract]:Since the beginning of the 21st century, China's social and economic scale and level have developed rapidly, a large number of high-tech science and technology have been widely used in the field of production and life, the medical technology and level has also been greatly improved. At the same time of economic development, investment in various social undertakings has also increased year by year, especially in the field of medical and health care. The number of medical institutions at all levels and the number of beds in various health institutions have increased year by year, while at the same time, Medical and health conditions in rural areas have also been significantly improved, new medical equipment and treatment technology have been used in the disease treatment process, the amount of new medical waste is increasing every year, and the variety of medical waste is changing greatly. The original reverse logistics system for medical waste disposal in Liaoning Province also needs to be changed accordingly, in order to comprehensively cover the new medical waste in the province and avoid the loss of medical waste caused by improper treatment. Reduce threats to the lives and health of local residents and patients. In view of the medical waste disposal demand under the new situation, this paper studies its processing flow and operation mechanism, and puts forward the topological structure of the regionalized reverse logistics network. On the basis of this, the paper optimizes the reverse logistics network of medical waste regionalization in Liaoning Province, makes a deep analysis of reverse logistics theory, enriches and expands the application field and research scope of reverse logistics theory. According to the present situation of medical waste disposal in Liaoning Province, the paper deeply analyzes the characteristics of the different output and geographical distribution of medical waste in different cities, and fully considers the constraints and limitations related to it. An integer programming model for regional layout of medical waste disposal enterprises is established. Using modern optimization methods and techniques and combining with modern heuristic algorithm, an improved genetic algorithm is designed to solve the model. Finally, the validity of the model and the algorithm is verified by an example. Optimized regional medical waste treatment reverse logistics network can effectively solve the problem of medical waste treatment in Liaoning Province, reduce the cost of medical waste treatment, form scale effect, improve treatment capacity and efficiency, and avoid waste of resources. The optimized regionalization of medical waste treatment model is more conducive to the relevant government authorities to monitor its treatment process, but also for the relevant policies and regulations to provide reference and advice.
