Research On Third-party Logistics Information System Modeling Based On Petri Net

Logistics Information is accompanied by the occurrence of logistics activities, throughout the entire logistics process, and plays a central nervous system role in the third-party logistics .Not only supports for logistics activities,but also connects with integration of the efficiency of the logistics system. It becomes increasingly important in the modern enterprise management strategy because of logistics information .It is nesscessary for enterprises gaining competitive advantages to establish the logistics information system to provide rapid, accurate, timely, overall message.The modeling analysis of logistics information systems, in fact its practical value and theoretical of research value, is widespread concerned widespread increasingly. A good system modeling is the basis and key of a flexible, reliable, available, scalable logistics information systems .System modeling has become the core of outstanding software development.On account of the features Petri Net in the logistics information system modeling, This paper first makes detailed explanation for the basic concept of Petri Net,then introduces the steps and methods of Petri Net modeling. As a study of the business functions of third-party logistics,decomposing the entire logistics business process and using Petri Net to construct all object models of strong express ability, setting up the whole logistics information system model through the object models changes. The model not only describes the integrity of the whole system of logistics and information flow process, but also it supports its logistics system to establish the dynamic process to some extent, and shows the Petri Net model for the description capacity of complex systems.Finally, based on the Petri Net model, the article builds simulation environment in the use of DaNAMiCS software ,analyzing the various nature of Petri Net model and simulating, for the assessment of actual system performance and structure,so on. Its research has the theoretical and practical value ,and provides with the builds to our third-party logistics information system .
