考虑回收-补偿约束的卫星城镇生活垃圾中转站选址研究

Study of the Layout Optimization of MSW Transfer Station in Satellite Towns Considering Recycling-co mpensation Constraints

为进行卫星城镇WSW中转站优化选址,本文结合城镇中转站选址经济、社会、环境负效应等相关影响因素细化分析,确定了城镇中转设施分步优化模型方法。该方法结合规范约束距离改进LSCP模型,于待选点中确定一次覆盖所有收集点的设施备选组合,而后应用综合考虑了建设运营成本、负效应、回收效率的多目标整数规划模型最终确定中转站位置、收纳量与服务分配方案。通过实例分析,验证了本文方法实用性与合理性。

Aiming at solving the location optimization problem of MSW transfer station in satellite towns,this paper puts forward the decoupled layout optimization model and method based on refinement analysis about eco-nomical,social and environmental site selection affecting factors of MSW transfer station.This thesis determines backup transfer station sets covering all the requirements by improved LSCP model considering corresponding code required distance.Furthermore,it calculates and determines the the position and capacity of ultimate WSW transfer station and collection depot sets by using integer programming model considered construction and opera-tion cost,negative effect,and recovery effect comprehensively.Finally,the efficiency and rationality of the method are validated by the case analysis in this study.
