摘　　要：研究一种新的α-幂过程维修模型.假设有两同型部件组成的冷贮备系统,以部件1的修理次数N为更换策略,利用更新理论,得出了平均费用率的表达式,并通过数值模拟实例得出了最优更换策略N*.A new α- power process maintenance model was studied. Based on the assumption of a cold standby system consisting of two identical components, the expression of average cost rate could be achieved by taking N, the failure number of the component 1, as replacement policy and using renewal theory. Then, the optimum replacement policy N＊ could be obtained through numerical simulation example.

关 键 词：冷贮备系统 α-幂过程 更换策略
