Optimum Preventive Maintenance Policies

Abstract

Two types of preventive maintenance policies are considered. A policy is defined to be optimum if it maximizes “limiting efficiency,” i.e., fractional amount of up-time over long intervals. Elementary renewal theory is used to obtain optimum policies. The optimum policies are determined, in each case, as unique solutions of certain integral equations depending on the failure distribution. It is shown that both solutions are also minimum cost solutions when the proper identifications are made. The two optimum policies are compared under certain restrictions.

Solving complex maintenance planning optimization problems using stochastic simulation and multi-criteria fuzzy decision making

“…Barlow and Hunter examined optimal use of preventive maintenance in their model in 1960 [8]. We summarize Barlow and Hunter model as:…”

The role of repair strategy in warranty cost minimization: An investigation via quasi-renewal processes

“…Imperfect repair is widely modeled as a combination of perfect and minimal repair. Barlow and Hunter (1960) are the first to combine the perfect and minimal repair under onedimensional warranties. The studies of Cleroux et al (1979), Boland and Proschan (1982), Phelps (1983) and Nguyen and Murthy (1984) give some other examples of combination repair/replace models under one-dimensional warranty.…”

Real-time health prognosis and dynamic preventive maintenance policy for equipment under aging Markovian deterioration

“…A usual practice of PM policy in many industries is to replace parts or perform maintenance when the equipment's running time reaches a pre-determined time length (Barlow and Hunter 1960, Blanks and Tordan 1986, Elsayed 1996. The advantage of this strategy is easy to follow.…”
