Logistics Grid Based on SOA and its Core Technologies
Yuanhui Li, Wei Guo Guan, Xian Wei Wu, Depeng Zhao · 2007
In order to resolve some typical problems existing in modern logistics information system, such as tight coupling, platform and language dependent and hard to extend, we establish a SOA based Logistics Service Grid (LSG) system model. This model adopts OGSA with SOA software model, deploys services in different granularity into different layers and achieves information sharing and interactive by services. Combining with business characters of logistics, this paper proposes core modules of this LSG frame and describes in detail about Task and Resource Dispatch module and scheduling algorithm based on credit of nodes. This paper indicates that SOA based LSG can improve loose coupling capability of heteriod data sharing and interoperation among multiple platforms efficiently, further to achieve dynamic dispatching.
