提出了一种运输-库存系统的建模方法，试图灵活地描述系统中的许多种物品订购运输，运输，存储在仓库，并交付给客户。该系统由若干“源”和“汇”组成。然而，在这项研究中考虑的问题是完全不同于传统的运输问题的线性规划。首先，任何数量的不同种类的项目可以被处理用于分析。其次，可以指定任何大小的运输卡车来运输任何数量的源-汇组合的物品。换句话说，在构建仿真模型时要指定运输卡车的容量。此外，可以根据需要指定任意数量的源和汇，以构建仿真模型。第三，在需求-供给环境下，基于接收端的库存策略，接收端向关联的供应端发出订单，并采用“拉动系统”。提出了一种有效的基于模块的建模方法来生成上述运输库存系统的仿真模型。该方法被应用到实际系统中。据发现，建立仿真模型的时间可以大大减少。此外，所提出的方法被发现是既实用又强大。
A method of modeling transportation-inventory systems is proposed in an attempt to flexibly describe the systems in which a lot of kinds of items are ordered to transport, transported, stored at the warehouses, and delivered to the customers. The system consists of a number of "sources" and "sinks". However, the problem considered in this study is totally different from the traditional transportation problem in terms of linear programming. Firstly, any number of different kinds of items can be treated for analysis. Secondly, any size of transportation trucks can be specified to transport items for any number of the source-sink combinations. In other words, the capacity of the transportation truck is to be specified in building a simulation model. In addition, any number of both sources and sinks can be specified as required to build a simulation model. Thirdly, the order by a sink is made toward the associated source, based on the inventory policy at the sink, and the "pull system" is adopted in the demand-supply environment. An efficient module based modeling method is proposed to generate simulation models for the above mentioned transportation-inventory systems. The proposed method is applied to the actual system. It is found that the time to build simulation models could be drastically reduced. Furthermore, the proposed method is found to be both practical and powerful.
