基于copula函数对相依部件系统可靠度的度量和改进

The Measurement and Improvement for System Involving Dependent Components Based on Copula Function

将copula函数引入可靠性理论中的一些典型不可修串并联系统,用以度量部件相依时系统的可靠度,给出了相依时系统度量的改进,并在理论上分析了独立与相依时系统可靠度的优劣.

The paper introduces copula function to some typical unrepairable series-parallel connection systems of the reliability theory to measure the reliability of the compounds dependence.It also gives methods to improve the system dependence and theoritically analyses the advantages and disadvantages between dependent and independent system reliability.
