城市地下物流服务供应链的流程设计：基于着色Petri网模型

Process Design of Urban Underground Logistics Service Supply Chain: Based on Colored Petri Net Model

摘要:

针对缺乏对城市地下物流系统（underground logistics system, ULS）在市场环境下的运营状况进行研究的问题，引入“ULS服务运营商”的概念分析ULS服务供应链的运作流程，即ULS服务运营商承接第三方物流服务企业和生产企业的物流外包业务以及普通客户的物流服务需求，通过运营平台统一调度、分配服务资源，实现城市物流的集成、共同配送以及服务流程的自动化；进一步利用赋时着色Petri网理论构建基于城市ULS的服务供应链Petri网模型，考察该服务供应链运作流程的可靠性和效率，并根据仿真数据对模型的运作方式和性能进行分析，以期为ULS在市场化环境下运营模式及运作流程的研究提供建模仿真思路参考。结果表明：该模型具备可靠性，符合设计预期；由仿真结果得到各流程运作耗时情况以及服务供应链整体的运作时间性能可知，售后服务、负责ULS终端分流的配送服务供应商和仓储服务供应商对城市ULS服务供应链整体的服务效率有较大影响，是供应链整体效率提升过程中需要关注的对象。

Abstract:

Urban Underground Logistics System is an urban logistics solution oriented to the problem of sustainable urban development. At present, although many scholars have studied it, a great deal of attention has been paid to the study of ULS network itself, and no one has yet explored its operation in the market environment. The study analyzes the operation process of ULS service supply chain, and on this basis, in order to examine the reliability and efficiency of this service supply chain operation process, a Petri network model of service supply chain based on urban ULS is constructed by using the colored Petri network theory. Detailed modeling ideas, model contents, and model simulation are proposed, and the operation mode and performance of the model are analyzed based on the simulation data.
