Analysis And Design Logistics Tracking And Decision-making System Base On Web Service

With the development of society and the progress of technology, the demands of moving target real-time monitoring in many fields are increasing, especially for vehicle monitoring of the logistics industry is more urgent needs. This paper studies the vehicle monitoring system which integrates GPS, GIS, GPRS and the Internet technology. GPS technology can be used to the real-time tracking of achieve; GIS electronic map can provide a visual carrier vehicle from which we can get the information of vehicles position and traffic management monitoring; GPRS is the data communication link between GPS and GIS, which makes remote monitoring of vehicles possible; Web Service technology can solve the problem of data and function sharing. These technologies will be shared together, which can make the real-time monitoring more convenient. Meanwhile, these technologies can provide audio-visual aided decision-making information.According to the logistics system on new technology needs and the development trend of software engineering, this paper apply GIS technology into logistics system, then design and implement a logistics vehicle tracking decision-making system. This article mainly includes:(1) Discussing and analyzing the key techniques of logistics tracking decision-making system.(2) Establishing the whole framework of the system which is based on logistics tracking decision-making system of requirement analysis, business process analysis and data flow analysis.(3) Discussing comprehensively based on the system design and realization process. In the design, the system adopts SuperMap Objects by SuperMap company. The system use Visual Studio (c #) as a development platform, which can realize the real-time monitoring of vehicle logistics, information tracking trajectory, vehicles playback, geographical information query, alarm functions, information management and so on.(4) In the Web service system design process, we adopt two kinds of design strategy which use business or function as the core, and the designing of Web service according to the strategy, finally analyze its feasibility, summarize the general design strategy of Web services.
