基于Petri网的舰载指控系统性能评价

舰载指控系统是广泛使用计算机技术的产物,分布式异步并行处理是它的突出特点。对它的分析和评价要解决的主要问题是系统结构的合理性和有效性。Petri网是描述和分析异步并发现象的一种有效的模型工具,本文以Petri网为工具,对舰载指控系统的结构性能、状态概率、任务的忙闲程度进行了定量和定性分析,从另一个角度对舰载指控系统性能进行了分析和评价,事实证明,这种方法是有效的。

The Capacity Evaluation of Shipboard Command and Control System Based on Petri Net

The shipboard command and control system is the product of widely using com-puter technology. The outstanding characteristic is its distributed asychronous parallel process-ing. The main point we want to solve for its analysis and assessment is the reasonableness and ef-fectiveness of system structure. Petri net is the powerful tool to discribe the appearance of asy-chrunous and parallel. Using Petri net, this paper analyses the structure performance, state prob-ability, the tasks'busy and idle degree quantitatively and qualitatively, in another point of view to analyse and assess the shipboard command and control system. The method is proved effica-cious.
