摘　　要：本文将工业生产组织和办公自动化领域的工作流理念引入到遥感在线产品的定制中,提出了一种融合JBPM工作流框架的遥感产品在线定制系统设计方案.本设计方案,具有以下几点创新:为适应遥感产品在线定制系统需求,将传统JBPM的三层框架转化为五层架构;将富客户端Flex技术应用到Web可视化流程定制中,增强了客户端浏览器的兼容性;采用JBPM API的二次开发技术,解决了个性化流程定制工具与JBPM引擎之间的流程驱动问题;采用面向SOA体系的整体设计框架,降低了系统中各模块间的耦合性.试验系统表明,本设计方案能有效的满足用户对个性化遥感产品的在线定制需求,并高效的完成用户所需遥感产品的生产.In this paper, the workflow technical, as an effective approach to execute the business processes in the industrial production organization and office automation area, is applied on the online order system of remote sensing products. Therefore, a new design of the online order system of remote sensing products based on JBPM which is one of major open source workflow management systems is proposed. The JBPM as an analysis framework is also motivated by the following factors. First, considering the characters of online order system of remote sensing products, the ordinary three-tier architecture of JBPM was changed to five-tier architecture. Second, according to the defects of web process designer in JBPM, the client is developed by Flex and using the SHH designer framework which success to solve many cross-browser compatibility issues. Third, the web service, the JBPM＇s production-driven designer and the service-oriented architecture are all developed to reduce coupling degree and make the process configuration simple. In order to prove the new design system＇s good performance, the testing system was build. The testing data on the testing system show that the new system can meet users＇ diversified and individualized needs of remote sensing products. And those remote sensing products can be produced well.
