| 摘 要： | 对组件软件可靠性进行优化工作时.不仅需要最大化其可靠性估计值.同时还要最小化可靠性估计方差以及测试代价.首先针对性地研究普通的组件软件可靠性优化策略,探讨该策略的缺点.提出并探讨一种改进的可靠性估计值排序策略(RPP-c策略),即增加测试代价考虑因素.最后为RPP-c策略建立优化模型,同时也给出相应的算法思想和实验数据分析.

| Abstract: | Optimizing the software components reliability,not only need to maximize the reliability of the estimates,but also need to minimize reliability estimation variance and testing costs.In this article,it was researched the normal software component reliability optimization strategy,and explored the shortcomings of this strategy.At the same time,it was also discussed an improved Reliability Prediction Prioritization strategy(RPP-c strategy),which added the factor of test cost.It was built the optimization model... |
