本文考察了在柏林市食品零售商的现实世界场景中，差异化城市交通政策的影响。构建了一个微观模型，该模型映射了几个战术和作战后勤决策。这是一个考虑运输成本随时间变化而启发式求解的单个企业的优化问题。通过分配成本和环境指标的变化，讨论和评价了区分区域、时间和车辆类型的城市货运政策的影响。该模型表明，限制在某一区域和车辆类型的政策措施，可以对整个研究区域产生重大影响。
This paper examines the effects of differentiated urban transport policies in a real world scenario of food retailers in the city of Berlin. A microscopic model is constructed which maps several tactical and operational logistics decisions. It is an optimization problem for individual firms which is solved heuristically considering time-of-day dependent transport costs. The impacts of urban freight transport policies that differentiate between area, time-of-day and vehicle type are discussed and evaluated by the variations of distribution costs and environmental indicators. The model shows that policy measures restricted to a certain area and vehicle-types, can have significant impact on the whole area under examination.
