考虑使用与维修优先权的冷贮备系统可靠性模型分析
Analysis of cold standby system reliability model considering use and repair priority
摘要
Abstract
Aiming at the problems that the parts of the equipment system had different critical im-portance,taking the cold storage system of multi-components with use and repair priority as the research object,a more generalized system reliability model was established by using the more applicability phase-type (PH) distribution instead of the exponential distribution and Weibull dis-tribution in the reliability modeling to describe the service life and repair time of system compo-nents .By using matrix analysis method,the analytical expressions of the reliability function, steady state availability and mean up-time and mean down-time of the system were obtained .The example was used to verify the applicability of the model,and the influence of the number of spare parts on the system reliability index was discussed .The results showed that the reliability modeling of the cold storage system with use and repair priority using the PH distribution not on-ly had good analytical properties,but also could effectively ensure the applicability of the model, w hich had good application value in engineering practice .关键词
