The proposed project aims at the development of an operational multi agent (MA) model to simulate freight transport demand, with focus on urban areas. In the model, logistics decisions made by shippers, recipients, and agents in charge of organising and performing physical transports are considered. Special emphasis is put on the interaction of the demand and supply sides in the freight transport market. This is done by incorporating both logistics decisions (such as lot size choice) and market related decisions (such as carrier choice) into the MA model. Important innovations are a consistent representation of the whole chain of decision makers from the shipper of a consignment via the logistics service provider to the carrier, and the generation of vehicle tour patterns from observed data.This project is concerned with those parts of the process that are closer to the physical transport of the goods. Building on an already existing modelling infrastructure that allows for carriers and their fleets, it is concerned with congestion feedback to the carrier agents and their reaction to it, and the feedback of the carrier agents to the logistics service providers. It is also concerned with externalities beyond congestion, such as emissions and noise.

拟议的项目旨在开发一个可操作的多智能体(MA)模型来模拟货运需求，重点放在城市地区。在该模型中，考虑了发货人、收货人和负责组织和执行实物运输的代理人所做出的物流决策。特别强调了货运市场中供需双方的相互作用。这是通过将物流决策(如批量选择)和与市场相关的决策(如承运人选择)纳入MA模型来实现的。重要的创新是从发货人通过物流服务提供商到承运人的整个决策者链的一致表示，以及根据观察到的数据生成车辆旅行模式。该项目关注的是过程中更接近货物物理运输的部分。它建立在现有的允许承运人及其车队使用的建模基础设施的基础上，关注向承运人代理的拥堵反馈及其对此的反应，以及承运人代理向物流服务提供商的反馈。它还关注拥堵以外的外部因素，如排放和噪音。
