‎This paper deals with the repair alert models‎. ‎They are used for analyzing lifetime data coming from engineering devices under maintenance management‎. ‎Repair alert models have been proposed and investigated for continuous component lifetimes‎. ‎Existing studies are concerned with the lifetimes of items described by continuous distributions‎. ‎However‎, ‎discrete lifetimes are also frequently encountered in practice‎. ‎Examples include operating a piece of equipment in cycles‎, ‎reporting field failures that are gathered weekly‎, ‎and the number of pages printed by a device completed before failure‎. ‎Here‎, ‎the repair alert models are developed when device lifetimes are discrete‎. ‎A wide class of discrete distributions‎, ‎called the telescopic family, ‎is considered for the component lifetimes‎, ‎and the proposed repair alert model is explained in detail‎. ‎Furthermore‎, ‎the problem of estimating parameters is investigated and illustrated by analyzing a real data set.
