一个实际危险废物产生问题的多目标可持续规划
A multi-objective sustainable planning for a real hazardous waste production problem
摘要：
卫生部门和工业过程产生的大量危险废物造成环境问题，污染空气、土壤和水资源，对人类健康构成重大威胁。提出了一种多目标混合整数非线性规划（MINLP）的可持续发展的危险废物选址-路径问题。在设计合适的废物收集系统时，会考虑设施的位置及运输危险废物及废物残渣的路线决定。该模型同时最大限度地减少了废物管理系统的总成本，运输和设施的总风险以及二氧化碳排放量。一个真实世界的案例研究来说明所提出的模型的适用性。为了说明可持续性的重要性，将原始模型的结果与不考虑可持续性的模型的结果进行了比较。结果表明，在不考虑可持续性的情况下，总成本、运输成本、场地风险和CO2排放量均有所增加，说明了可持续性的重要性。此外，从最佳结果中获得的管理见解将使管理人员能够在危险废物管理系统中做出更好的决策。
英文摘要：
A significant amount of hazardous waste generated from health sectors and industrial processes has posed a major threat to human health by causing environmental issues and contamination of air, soil, and water resources. This paper presents a multi-objective mixed-integer nonlinear programming (MINLP) formulation for a sustainable hazardous waste location-routing problem. The location of the facilities and routing decisions for transporting hazardous waste and the waste residue is considered to design a suitable waste collection system. The presented model simultaneously minimizes the total costs of the waste management system, total risks from transportation and facilities, along with CO2 emissions. A real-world case study is presented to illustrate the applicability of the proposed model. To illustrate the significance of sustainability, the results of the original model are compared with the results of the model without considering sustainability. It indicates that, under the condition when sustainability is not taken into account, total cost, transportation, and site risk along with CO2 emission increased, which in turn demonstrated the importance of sustainability. Furthermore, the managerial insights gained from the optimal results would enable the managers to make better decisions in the hazardous waste management system.
