Correlation of Component States and Computation of Probability Distributions for System Performance Measures

这项研究的目的是当部件状态为相依随机变量时，得到系统性能度量的概率分布。将研究组件状态中的关联结构与系统结构的相互作用，以确定其对计算系统性能度量的分布的算法的影响。这项研究将通过考虑一种特定的模型来启动，该模型源于冲击，这些冲击会影响到“双星相干系统”的几个组成部分。预计结果将确定相关结构的类别，这将允许开发有用的算法来计算系统性能衡量的分布。这种理论研究有可能产生更好的技术来预测计算机网络或自动化制造等不同领域中出现的复杂系统的可靠性。

This research project is concerned with obtaining a probability distribution for a system performance measure when component states are dependent random variables. The interaction of correlation structure in the component states with the system structure will be investigated to determine its impact on algorithms for computing the distribution of the system performance measure. The research will be initiated by considering a specific model derived from shocks that affect several components of a 'binary coherent system.' It is expected that the results will identify classes of correlation structures which will permit the development of useful algorithms for calculating the distribution of the system performance measure. This theoretical research has the potential of yielding better techniques forevaluating the reliability of complex systems arising in diverse fields such as computer networks or automated manufacturing.
