针对由一个修理工、两同型部件组成的带有延迟修理退化冷贮备可修系统，提出了一种新的维修更换模型。在假定部件工作寿命、修理时间和延迟修理时间为一般分布和故障部件不能“修复如新”的条件下，选取系统中部件1的故障次数 N为更换策略，以长期运行单位时间内的期望费用为目标函数，通过更新过程和几何过程理论建立数学模型，导出了目标函数的解析表达式。最后还通过数值例子验证了该方法的有效性，并对所得结果进行了讨论。
針對由一箇脩理工、兩同型部件組成的帶有延遲脩理退化冷貯備可脩繫統，提齣瞭一種新的維脩更換模型。在假定部件工作壽命、脩理時間和延遲脩理時間為一般分佈和故障部件不能“脩複如新”的條件下，選取繫統中部件1的故障次數 N為更換策略，以長期運行單位時間內的期望費用為目標函數，通過更新過程和幾何過程理論建立數學模型，導齣瞭目標函數的解析錶達式。最後還通過數值例子驗證瞭該方法的有效性，併對所得結果進行瞭討論。

To study a kind of deteriorative repairable cold standby system with delay repair consis-ting of two -identical components and single repairman ,this paper proposes a kind of new maintenance and replacement model .Assuming that the working life ,the delay repair time and the repair time are general distributions and the component after repair is not “as good as new” ,by using renewal process and geometric process ,we consider a kind of replacement policy of the system based on the failure num-ber of the component 1 and choose the long-run expected cost per unit time as objective function .By u-sing renewal process and geometric process theory ,we establish mathematic models and the explicit ex-pressions of the objective function are derived .Finally ,we validate the effectiveness of the method through a numerical example and discuss the results .
