Title: Decision of Preventive Maintenance and Replacement of Single-unit Systems with Gamma Process
Abstract: A decision model for preventive maintenance and preventive replacement of a single-unit system is proposed in this paper based on continuous detection.A gamma distribution is applied to model the material degradation.The degrading decrement after the imperfect maintenance action is assumed as a random variable normal distribution.This model aims to obtain the preventive maintenance frequency and the threshold of preventive maintenance and preventive replacement with the expected cost rate within system lifecycle as the optimization objective.The rationality and feasibility of the model are proved through a numerical example.
