“…Several papers have been published in the literature dealing with the topic of equipment replacement scheduling and its models. Frequently, in this literature the selection of replacement policies is based on cost criteria (Barlow and Hunter, 1960;Beichelt and Fischer, 1979). In addition, a number of assumptions have been identified to justify preventive maintenance.…”

The subject of investigation reported in this paper is the determination of an optimal replacement time for equipment that deteriorates with time. The following hypothesis is proposed and investigated. While a piece of equipment is in the final stages of its life span, i.e. the wear‐out phase, the application of preventive replacement strategy at constant time intervals reduces total down‐time. The novelty of the approach used in this research lies in the conversion of the more complicated classical constant‐interval replacement model to a simplified but nonetheless effective model. Results are shown for a case where the equipment time‐to‐failure has a normal distribution. These results also hold for a Weibull distribution with known shape and scale parameters. The simplified methods proposed in this paper can assist maintenance managers to better make economic decisions about equipment maintenance.
