We consider a replacement policy for a multiple component cold standby system, and after we analyze this policy, we want to get the mean total cost rate and the preventive policy to make it the lowest. In this system, the failure rate of the component in operation is constant, and the inspection will control all the processes of the operation. The system is inspected at random points over time to determine whether it is to be replaced. During the process, the replacement decision is based on the number of failed components at the time of inspection.
