本文针对物流空间信息Web服务所涉及的服务获取、集成和应用等主要问题,以OGC Web 服务框架为基础,将空间信息服务延伸到物流领域,建立了物流空间信息服务集成体系结构和Web服务的集成模式,明确了物流空间信息服务体系的构成要素及其内在关系。在此基础上,扩展和细化了物流空间信息的服务元素,设计了Petri网的服务组合模型和面向物流的空间信息Web服务引擎LogisticsWeb,提出一种新的物流空间信息服务的动态访问、实时获取与协同集成的解决方案。最后,以Web服务的集成模式,开发了相应的服务引擎和软件系统,有效地实现了物流空间信息服务的协同集成和动态组合,充分体现了将空间信息服务与物流管理融合的实践意义。
Logistics essentially refers to material entities movement process with distinct spatial measurement and spatial characteristics, where integration and application of spatial information techniques and other modern techniques of logistics management are needed. This is a new interdisciplinary research fields where to extent spatial information services combined with web services and geospatial analysis to the area of logistics management, and then integrate the concept of spatial information services into modern logistics services system to carry out logistics oriented spatial information web services access, integration and application. What's more, the key point to analyze logistics spatial phenomenon from the geographic perspective. Based on OGC web service framework, this paper we have put forward design and built the architecture of logistics spatial information services mainly include the mechanism for service integration, high-efficiency call and service composition and the model of integration based on web services, which clear its inherent elements and the relationship. Besides, we designed and developed the mechanism for service composition based on Net-Petri and Logistics Web of web service engine, which resolved the problems of dynamic access, high-efficiency call and real-time integrate to the logistics spatial information services. This work provided a new way and measure to the spatial information services being further developed and applied in the logistics area. By this way, even though the logistics information system constructors don't have a professional GIS background, they can also call spatial information service in their own programs. According to our study, the means of techniques of integrating and applying the logistics spatial information services, which achieve the dynamically composited and collaboratively integrated effectiveness and the practical experience for logistics spatial information service system construction.
