基于WebGIS的第四方物流跟踪及应急系统设计与实现

Design and implementation of tracking and emergency system for forth-party logistics based on WebGIS

随着现代物流的迅速发展,物流模式由第三方物流向第四方物流过渡。作为物流过程的中介者,第四方物流需要对物流过程进行全程跟踪并且作出相应的决策,因此,为第四方物流提供了一个基于WebGIS的物流跟踪及应急决策系统。根据第四方物流业务的需要,对物流过程中涉及的订单即时跟踪、车辆动态监控、应急预案决策生成等进行了有效的模拟和实现。系统将电子地图应用于跟踪与应急决策系统,为用户提供了一个可视化载体,并在运输车辆动态监控过程中融合使用GPS、GPRS和WebGIS技术,实现了物流运送过程中的动态可视化效果;同时在应急预案决策中引入本体和知识推理,利用本体推理实现自动发现,制订规则实现自动关联,在很大程度上提高了应急处理的速度和效率。

With the rapid development of modern logistics, logistics model transform from third-party logistics （3 PL） to forthparty logistics （4PL）. This paper provided a platform of 4PL tracking and emergency decision-making system based on Web- GIS. According to the 4PL business needs, the estabilishment of tracking and emergency decision-making system conducted effective simulation and relization for the issue involved in logistics such as real-time tracking of order and vehicle dynamic monitor, the choice of 3PL companies, the generation of emergency decision-making. The system would build proprietary electronic maps basing on information of all kinds of users and 3PL companies, which provided a visual carrier that users could easily get relevant information. The system could monitor the transport vehicles by using the integrated technology of GPS, GPRS and WebGIS, which would achieve the dynamic visual effects of logistics delivery process. The research results and related software realization provide a platform of 4PL tracking and emergency decision-making system, which can help to guide the current logistics tracking and visual effects in practice.
