实际上，世界上每一个国际、国家或区域货运模式系统都没有明确处理物流选择（如货运规模考虑或使用配送中心）。本文论述了一种新的物流模型的发展及其在挪威和瑞典国家货运模型系统中的应用。这一物流模式在单个公司对公司（发送者对接收者）关系的层面上运作，并模拟了国内所有（数百万）这些关系、出口和进口的装运规模和运输链的选择。确定性成本最小化的物流模型已建成挪威和瑞典。完全随机效用物流模型尚未估计的分类数据，但这是计划为两国。对瑞典而言，对选择运输方式和运输规模的更有限的分类模型作了估计。
Practically every international, national or regional freight transport model system in the world lacks explicit treatment of logistics choices (such as shipment size considerations or the use of distribution centres). This paper deals with the development of a new logistics model and its application within the national freight model systems of Norway and Sweden. This logistics model operates at the level of individual firm-to-firm (sender-to-receiver) relations and simulates the choice of shipment size and transport chain for all (several millions) these relations within the country, export and import. A logistics model with deterministic cost minimisation has been constructed for both Norway and Sweden. The full random utility logistics model has not yet been estimated on disaggregate data, but this is planned for both countries. For Sweden, more limited disaggregate models for the choice of mode and shipment size have been estimated.
