Finding the Optimal Preventive Maintenance Time for the Second South Baghdad Gas Electricity Distribution Station Using Reliability Function Techniques

Abstract

The productive efficiency of any industrial organization depends on the success of maintenance operations that are based on organizing maintenance management, and preventive maintenance is part of this success, which is used to maintain the continuity of machine operation. In this research, the optimal time for preventive maintenance of the second South Baghdad Gas Electricity Distribution Station was determined using a method The reliability function, where the optimal maintenance period at the lowest cost was determined by estimating the parameters of the Type – II Generalized Log Logistic Distribution using the maximum likelihood method, and the best time was approximately only sixteen days according to the first shape parameter, and only a month and a half according to the second shape parameter.
