摘要
性能计算对随机Petri网模型的性能分析具有重要作用。以研究随机Petri网性能计算软件关键技术为主要目的,提出了一种独立于计算(CIM)的性能计算软件体系结构元模型,并以此元模型为依据,遵循面向对象的系统分析与设计方法给出该软件独立于平台(PIM)的软件体系结构模型,对核心算法设计方案采用先计算基础性能数据,再计算扩展性能数据的策略分步骤完成,并给出了基于MVC模式实现的PSM模型实例和一个电子农务应用案例。最后,给出了同类性能计算软件的设计可适用此开发方法的初步结论。
Performance computation has significant meaning to performance analysis of models based on stochastic Petri net(SPN). To aim at research on the key technology of performance computation software for the models, firstly,give a compute- independence metamodel (C/M) for the software- architecture based on SPN, and according to it,give a platform- independence model(PIM) through methods of oriented - object. Promoted a design project of firstly calculating foundation performance data and again calculating expanded performance data. Finally,give a platform- specified model case based on MVC and an electronic - agriculture services case. In the end, a conclusion that similar software can adopt the method is made.
