基于工作流模型的企业铁路调度指挥与监控系统研究

Dispatching and controlling system of enterprise railway based on workflow model

根据企业专用铁路特点,设计了调度指挥与监控一体化方案。为了协调多个子系统的活动,采用工作流技术构建系统软件平台,实现业务过程的自动化。基于Petri网定义的基本工作流网络为系统业务流程建模,针对建模中存在的问题,提出增加颜色扩展描述信息,增加复合颜色变量扩展,提高工作流网络抽象能力及描述能力,使扩展工作流网络成为复杂系统建模的有力工具。

According to the characteristics of the enterprise railway, an integration scheme of dispatching and controlling was designed. In order to coordinate the sub-systems, the scheme worked on workflow technique to realize the automation of the working process. To solve the problems in modeling the system with the standard workflow net, standard workflow model was expanded. In the expanded model, the color was used to describe information flowing in workflow net, and the compounded color identifier variable was used to represent the individuals. The expanded model has better structure, better abstracting capability and extensive description capability.
