Abstract
The failure repair process of a continuously operating device is studied in this research. Different cases that incorporate modeling of equipment deterioration, inspection, and maintenance for optimal maintenance policy are proposed. Markov processes are used to determine state probabilities, and the optimal value of the mean time to preventive maintenance is determined by maximizing the availability of the equipment with respect to the meantime preventive maintenance. The approach uses models that assume that equipment can fail due to both deterioration and random failures. Preventive maintenance can be performed from each working state to avoid deterioration failure. Economic effects are integrated into all the models to determine the costs associated with the preventive maintenance policy. The computational work involved in developing algorithmic solutions for the developed Markov models is perfomed using Matlab® software. The results of how the obtained maintenance rate impacts the equipment availability are discussed. This study is helpful for engineers to determine optimal maintenance policy of equipment.
