Abstract: As the civil aviation develops, organization rebuilding and task reassigning will be repeating in a long period. Workflow technology provides separation of the business procedure logic and its IT operational support, enabling subsequent changes to be incorporated into the procedural rules defining the business process. Therefore, workflow technology is applied in civil airport ELV (Electronic Low Voltage) information system based on middleware service layer, to avoid unnecessary overlapping development of computer management and control system. Firstly, the construction of ELV system is was analyzed and content of workflow modeling is was introduced. Secondly, three kinds of ELV system architecture based on workflow technology are were discussed. Finally, the realization of distributed prototype system taking on main control workflow engine is was described.

Key words: workflow, civil airport, ELV information system

摘要： 我国民航业正逐步向着与国际进一步接轨的方向发展,机构重组和重新分工将在未来的很长一段时间内不断进行。工作流技术提供了业务过程逻辑与计算机操作支持的分离,从而可以通过修改过程规则来重新定义业务过程,因此将工作流技术引入具有基于信息发布服务中间层的弱电信息系统中,能够避免由于上述原因带来的不必要的重复开发。首先对弱电信息系统的组成进行了分析,并介绍了工作流的建模内容;然后讨论了基于工作流的民航机场弱电信息系统的三种系统结构方案;最后给出了具有主控引擎的分布式原型系统的具体实现内容。
