A study on the structure analysis of a logistics information model based on UML

In this paper, we propose a new method to analyze physical distribution models written using UML (Unified Modeling Language). Recently, the use of automated (information technology, IT) management systems for complex corporation activities and processes has been adopted by many companies. IT is, of course, a powerful tool for physical distribution processes. However, it is impossible to construct an effective system without practical knowledge. Moreover, it is sometimes difficult for system engineers constructing information systems to understand the practical knowledge and essence of activities in actual physical distribution processes. Sometimes workers are entirely ignorant when it comes to the use of information systems. From the background mentioned above, it is necessary to construct a good tool that enables both sides, the system engineers and distribution workers, to communicate and exchange information. UML is an efficient language to use for such communications. However, it is not easy to clarify complex UML models. We therefore introduce a method to analyze the structure of physical distribution described by UML and apply it to a standard logistics model. The proposal is based on multivariate analysis. Using this method, we can extract the structure of complex UML diagrams.
