中文摘要:

      目的 研究考虑企业效益下高校快递包装回收系统的系统优化问题，以改善高校校园因快递包装造成的环境污染。方法 针对大学校园快递包装的回收特点，应用第三方企业回收的包装回收模式，引入包装破损率对包装进行分类回收，考虑再生效益对回收系统的影响，利用系统动力学方法建立校园环境下的快递包装回收模型。进一步，从快递包装平均重量与校企合作水平出发，设计4个不同仿真方案，通过Vensim PLE仿真软件对模型进行验证，分析了影响快递包装回收效果的主要因素，并对主要影响因素进行了敏感性分析。结果 实例验证可知，仅减小快递包装的平均重量对于高校快递包装回收现状改善效果不明显。通过增大校企合作水平影响因子、简化快递包装、提升学生环保意识相结合，可使校园被废弃包装量、废弃包装填埋量降低，企业回收效益明显，校企合作更加紧密。结论 提高校企合作水平可以显著改善快递包装的回收效果，提升企业效益，同时减少包装平均重量可以有效控制校园废弃包装的累积速率与填埋量，对于发展绿色物流具有重要意义。

英文摘要:

      The work aims to study the system optimization problem of the express delivery packaging recycling system in universities in consideration of enterprise benefits, so as to improve the environmental pollution caused by express packaging in university campuses. According to the recycling characteristics of express delivery packaging in university campus, the packaging recycling mode recovered by third-party enterprises was applied, and the packaging damage rate was introduced to classify and recycle the packaging. Considering the influence of regeneration benefit on the recycling system, the express packaging recycling model under the campus environment was established by system dynamics. Further, from the average weight of express packaging and the level of cooperation between schools and enterprises, four different simulation schemes were designed, and the model was verified by Vensim PLE simulation software, and the main factors affecting the recycling effect of express packaging were analyzed, and the sensitivity analysis of the main influencing factors was carried out. The example verification showed that only reducing the average weight of express packaging was not obvious for the improvement of the status of express delivery packaging in colleges and universities. By increasing the influence factor of school-enterprise cooperation level, simplifying express packaging, and enhancing students' environmental awareness, the amount of discarded packaging and waste packaging in the campus could be reduced, the recycling efficiency of enterprises was obvious, and the cooperation between schools and enterprises was closer. Increasing the level of school-enterprise cooperation can significantly improve the recycling effect of express packaging and improve the efficiency of enterprises, and reducing the average weight of packaging can effectively control the cumulative rate and landfill volume of abandoned packaging in campus, which is of great significance to the development of environmental logistics.
