兰州大学学报（自然科学版），2023，59(3）／6月JournalofLanzhouUniversity(NaturalSciences),2023,59(3)/June基于Python的城市生活垃圾收运物流系统仿真与优化张矢宇，王自由，褚宇航武汉理工大学交通与物流工程学院，武汉430063摘要：以武汉市杨园街道为例展开调查，使用Python进行程序设计，构建生活垃圾收运物流系统仿真模型.对模型存在的收集线路不合理、系统总运行时间过长、车辆利用率较低等问题，通过构建运输线路规划模型，使用贪心算法对收集车辆的运输线路进行优化；对转运站和车辆收运工作时间安排进行优化调整；对生活垃圾转运车辆的配置方案进行优化.优化后的系统模型仿真结果显示，在完成每天垃圾清运量的前提条件下，系统运行时间下降约1h，运输成本下降约19.54%；收集车辆装载率保持满载的前提下，转运车辆装载率提高约13.05%，优化效果显著。关键词：垃圾收运；系统仿真；系统优化；Python；城市生活垃圾中图分类号：U491文献标识码：A文章编号：0455-2059(2023)03-0358-07D0I:10.13885/j.issn.0455-2059.2023.03.010AsimulationofdomesticwastecollectionandtransportationlogisticssystembasedonPythonZHANGShi-yu,WANGZi-you,CHUYu-hangSchoolofTransportationandLogisticsEngineering,WuhanUniversityofTechnology,Wuhan430063,ChinaAbstract:TakingYangyuanStreetinWuhanCityasanexample,bymeansofPythonforprogramming,asimulationmodelofthedomesticwastecollectionandtransportationlogisticssystemwasconstructed.Thesimulationresultsshowedthatthecollectionroutewasunreasonable,totaloperationtimetoolong,andtheutilizationrateofvehicleslow.Inviewoftheproblemswiththemodel,anoptimizationwascar-riedoutfromthetransportationroute,collectionandtransportationplanandvehicleconfiguration,tocon-structatransportationrouteplanningmodel,viagreedyalgorithms,tooptimizethetransportationrouteofdomesticwastecollectionvehiclesandimprovedomesticwastetransferstationsandvehicles.Thecollec-tionandtransportationplanofthecompanywerethusoptimizedandadjustedandaconfigurationplanofthedomesticwastetransfervehicledesigned.Thesimulationresultsoftheoptimizedsystemmodelshowedthat,incompletingthedailywasteremovalandtransportationvolume,thesystemrunningtimewasdecreasedbyabout1h,andthet...
