在本研究中，我们研究了对故障单元进行两阶段修复的两单元冷备用系统的成本效益分析。我们讨论了两台机组冷备用系统的两阶段修复等待时间的概念。修复过程分为两个阶段。第一阶段，机组的修复过程开始但未完成；相反，该过程在第二阶段完成。两个阶段之间经过的时间称为等待时间。再生点过程技术已用于测量有效性。以数值和图形方式获得时间相关可用性、稳态可用性、可靠性（MTTF）和利润函数。 MTTF、稳态可用性和利润函数随着故障率和等待率的增加而下降。
In this study we investigated the cost-benefit analysis of a two-unit cold standby system with two-stage repair of a failed unit. We discuss the concept of waiting time with two-stage repair for a two-unit cold standby system. The repair process is divided into two stages. In the first stage, the repairing process of the unit is started but it does not get completed; instead the process is completed in the second stage. The elapsed time between two stages is called the waiting time. Techniques of regenerative point processes have been used to measure the effectiveness. The time dependent availability, steady state availability, reliability, (MTTF) and profit function were obtained numercially and graphically. The MTTF, the steady-state availability and the profit function decreased with respect to the increase of failure rate and waiting rate.
