由于Petri网模型具有强大的描述离散事件系统的能力,电信综合结算系统采用了基于Petri网的系统模型,作为分析工作流模型的理论基础。讨论了结算系统优化求解模型和工作流Petri网模型。结算系统建立了全局流程管理机制,调度系统统筹管理任务、进程和资源等各方面要素,成功减少了计算机资源消耗,也使结算系统的监控、配置、操纵更加方便和智能。 Because Petri nets model possesses powerful ability to describe discrete event system, telecom integrated settlement system uses Petri nets based system model as theoretical basis for analyzing workflow model. Discusses the settlement system optimization solution model and workflow Petri net model. Settlement system established a global process management mechanism, scheduling system co-management tasks, processes and resources and other elements, successfully reducing the consumption of computer resources, but also to the settlement system monitoring, configuration, manipulation more convenient and intelligent.
