Public Logistics Information System

The paper distinguishes the definition of logistics and supply chain, which are different in many literatures. Based on the result, extending enterprise model, peer-to-peer enterprise model and galaxy model is developed. Extending enterprise model serves for the logistics application of core enterprise, and peer-to-peer enterprise model servers for many enterprises. Both models are used to design logistics information system. The galaxy model explains the relationship between the models. According to the peer-to-peer model and the theory of virtual enterprise, we established the logistics information platform for the public, called Virtual Logistics Enterprise (VLS). Clients of VLC include purchaser, seller, carrier and so on, and they can purchase, sale, transport and store commodity. According to its function, VLC is divided into purchasing platform, virtual warehousing, sale platform and public information management, virtual transportation, customer management, which are mostly described as 8 use cases with Unified Modeling Language.VLC is a integrated information system in high level and a hard task to implement, so it's necessary to establish scientific mechanism to ensure the successful implementation and abate or eliminate the project risk. Some useful suggestions about realizing VLC are put forward in the paper. At the last part of the paper, the case of Digital China Corporation explains what enterprise can profit from the VLC.The research is significant in practice and theory. VLC is a solution of integrated supply chain information. The realization of VLC can reduce social cost of logistics operation and improve the benefit of enterprise.
