Probabilistic analysis of a two-unit cold standby system with two-phase repair and preventive maintenance
Abstract The paper deals with the cost-benefit analysis of a two-unit cold standby system with two-phase repair of a failed unit and preventive maintenance (PM). The PM of an operative unit starts after a fixed amount of time which is made only if the other unit is in standby. The distributions of failure time and time to accomplish PM are negative exponential while the distributions of repair times and time until PM are all general. Various economic reliability measures of interest to system designers as well as operations managers have been obtained using regenerative points in MRP.
