Working-Condition Importance Measures for Multi-Component Systems

摘要

In industry, the working conditions of systems are complicated. It may contain some adverse/favorable factors that can damage/improve components' reliabilities compared to that in the designed working condition. The same product/system may also work in different sites whose conditions exist significant differences to each other. Then the reliability of the system is not only determined by system structure, components' designed reliabilities, etc. It can be also influenced by its working condition. In previous researches in importance measures, the environmental influence on system reliability has been paid little attention. In this paper, two working-condition importance measures for multi-component systems are introduced.
