摘　　要：一般认为串联系统多部件中至多允许一个部件失效且其他部件服从于统计独立情况.论述了修理期间部件无老化的串联系统分别在统计独立情况下及包含共因失效情况下的稳态可用度,并对给出一般表达式.In this paper, The steady-state availability of a series-systems without aging of components during the repair of another one is investigated under the s-independent case on allowing for at most one failed component at any time, and the steady-state availability is deliberated conditioned on allowing for common failure, and works out a general expression.

关 键 词：串联系统 可用度 老化 条件概率 统计独立(s-独立)
