Caldeira Duarte, J. e Guedes Soares, C. (2007), “Optimization of the Preventive Maintenance Plan of a Series Components System with Weibull Hazard Function”, Proceedings of the Summer Safety and Reliability Seminars, Sopot, Polónia
In this paper we propose an algorithm to calculate the optimum frequency to perform preventive maintenance in equipment that exhibits Weibull hazard function and constant repair rate in order to ensure its availability. Based on this algorithm we have developed another one to solve the problem of maintenance management of a series system based on preventive maintenance over the different system components. We assume that all components of the system still exhibit Weibull hazard function and constant repair rate and that preventive maintenance would bring the system to the as good as new condition. The algorithm calculates the interval of time between preventive maintenance actions for each component, minimizing the costs, and in such a way that the total downtime, in a certain period of time, does not exceed a predetermined value.
