Abstract

This paper introduces improvement factors in hazard rate and age for a sequential preventive maintenance (pm) policy and analyzes two imperfect pm models: 1) pm reduces the hazard rate while it increases with the number of pm's and 2) pm reduces the age. The pm is done at intervals \(x_ k\) \((k=1,2,...,N)\) and is imperfect. The optimal policies to minimize the mean cost-rates are discussed. The optimal pm sequences \(\{x_ k\}\) are computed for a Weibull distribution.
