Urban Logistics Services Supply Chain Process Modelling Based on the Underground Logistics System via the Hierarchical Colored Petri Net

The implementation of the urban underground logistics system (ULS) can effectively mitigate contradiction between surging demand and increased negativity logistics. widespread ULS still suffers from a lack research into its operation in marketplace, although on technology network design appears to be sufficient. A new supply chain for service based (ULS-SSC) was proposed, as embedded could lead evolution role participants. This article analyzed organizational structure characteristics ULS-SSC designed top-down process model functional subsystems relationship using hierarchical colored Petri net (HCPN). simulation results show that integrated information management platform integrate resources operate under two main modes designed. high-time delay intermediate links upgraded by optimization, with initial pickup terminal distribution improved through outsourcing collaboration. findings provide insights feasibility market help stimulate ULS.
