The reliability optimization problem arises along with the increasing demands for products’ performance in practical engineering. Importance measures are capable of selecting critical components to gain the greatest improvement in system reliability with the constraint of maintenance cost. The characteristics of importance measure for four kinds of typical systems are discussed to illustrate the usage of importance measure in the practical reliability optimization. A reliability optimization mod...

The circular-consecutive -out-of-: system (Cir/Con//: system) usually consists of components arranged in a circle where the system fails (works) if consecutive components fail (work). The optimization of the Cir/Con// system is a typical case in the component assignment problem. In this paper, the Birnbaum importance-based genetic algorithm (BIGA), which takes the advantages of genetic algorithm and Birnbaum importance, is introduced to deal with the reliability optimization for Cir/Con// system...
