摘要: 分析了资源共享的几种模式,利用随机Petri网理论进行建模,通过数学推导,分析了不 同资源共享模式下影响系统性能的因素。通过实例分析,验证了在资源平等竞争的环境下,完全共享 模式性能优越于部分共享模式。

Abstract: Several kind of resources sharing scheme were analyzed. By using stachastic petri nets theory, the resources sharing scheme was modeled and mathematically analyzed. Finally,an example demonstrates that absolute resources sharing is superior to partial resources sharing provided pairly competing resources.

Key words: shared resources, stochastic Petri nets, Markov chain, performance ananlysis
