文摘

In this paper, two optimal problems for a system composed of a main unit and a standby with common cause failure and critical human error are considered. The optimal repair rates for the optimal reliability and the optimal balance between system availability and repair cost are respectively discussed by constructing suitable objective functions and corresponding permitted sets with functional analysis method. Some numerical examples are presented at the end of the paper.
