摘　　要：针对一类新型单部件退化可修系统,利用概率论等数学知识建立了维修更换模型.在两种策略(工作寿命T和故障次数N)下分别求出了系统经长期运行单位时间内期望效益的表达式,并通过数值例子验证了该方法的有效性.To study the new repairable deteriorating system considering one unit, a kind of new maintenance and replacement model is established by using probability theory and other mathematical knowledge. The expressions of the long-run expected profit per unit are respectively derived under the two kinds of replacement policies （the working age T and the failure number N for the system） ,and the effectiveness of the method is also validated through a numerical example.
