微观仿真和基于Agent的方法可以成功地应用于交通运输政策分析，这一点已得到广泛的认可。然而，物流决策和货运参与者之间的复杂关系使这成为一项具有挑战性的任务，也是货运模型的发展仍然落后于客运模型发展的原因。本文提出了一个多代理货运模型，其中物流决策被分离为两个不同的角色：运输服务提供者，创建运输链;承运人，规划图尔斯和调度车辆。这两种代理类型都可以在各自的级别上进行整合，实现规模经济。模型的最低层包含单个货运车辆，将其集成到MATSim交通仿真中，以创建货运和客运交通的集成模型。乘客需求的变化、交通系统中的干扰或政策措施可以被货运司机发现，并向上传播，以影响车辆调度和运输链建设水平的决定。作为概念验证，我们设置了一个场景，其中一个虚构的货运运营商为一组客户提供服务。应用案例分析，虚构一个货运经营商，为客户提供运输服务，验证了货物运输可以在不同的运输条件和政策措施下进行仿真。© 2012由爱思唯尔有限公司出版第七届国际城市物流大会评选和/或同行评审
It is widely recognized that micro-simulation and agent-based approaches can successfully be applied in transport policy analysis. However, logistic decisions and the complex relationships among freight actors make this a challenging task and a reason why the development of freight models is still behind the development of passenger models. In this paper, we present a multi-agent freight transport model in which logistics decisions are separated into two different roles: Transport service providers, which create transport chains, and carriers, which plan tours and schedule vehicles. Both agent types can consolidate on their respective level and realise economies of scale. The lowest tier of the model, which contains individual freight vehicles, is integrated into the MATSim traffic simulation to create an integrated model for freight and passenger traffic. Changes in passenger demand, disturbances in the traffic system or policy measures can be picked up by freight drivers and propagated upwards to influence decisions on the levels of vehicle scheduling and transport chain building. As proof of concept, we set up a scenario with a fictitious freight operator serving a set of customers. We demonstrate that freight traffic can be simulated under different traffic conditions and policy measures. © 2012 Published by Elsevier Ltd.
