Purpose – The purpose of this paper is to propose a model that captures the fuzzy events is proposed to find the optimal periods of warranty policies. The model considers repair and replacement actions in the warranty period. Design/methodology/approach – The study transforms the reliability...

Purpose – The purpose of this paper is to consider a General System Configuration (GSC), whose particular cases are all the popular system configurations. In reliability engineering one comes across various system configurations, for example, series, parallel and k‐out of‐m system models,...

Purpose – The purpose of this paper is to model the occurrences of successive failure types and times to failure of the two repairable machine systems. Design/methodology/approach – Historical data on failure types and time to failures of the given machine systems (4 nos) were gainfully...

Purpose – In reliability studies, interests in discrete failure data came relatively late in comparison to its continuous analogue. Also, discrete failure data arise in several common situations. So, in this paper the authors try to study some reliability concepts such as reversed variance and...

Maintaining a high level of availability of weapon systems during battles becomes important from the point of view of winning the battle. Due to attrition factors (failure due to battle damage and unreliability) and logistic delays in the repair process, maintaining the required level of...

Maintenance management is expected to plan for all maintenance activities for the life of the equipment. It must be able to forecast and plan the future maintenance requirements of spares, man‐hours and total costs. As equipment ages and enters the wear‐out stage, with increasing failure...

Purpose – To investigate the optimal burn‐in time from the perspective of minimizing the expected total cost (i.e. manufacturing plus warranty costs) per unit of product sold under a failure‐free renewing warranty policy. The conditions indicating when burn‐in becomes beneficial were...

Purpose – The purpose of this paper is to provide maintenance personnel with a methodology for using masked field reliability data to determine the probability of each subassembly failure. Design/methodology/approach – The paper compares an iterative maximum likelihood estimation method and...

Purpose – The purpose of this paper is to encourage the integration of Lean principles with reliability models to sustain Lean efforts on a long‐term basis. It seeks to present a modified FMEA that will allow Lean practitioners to understand and improve the reliability of Lean systems. The...

Purpose – The purpose of this paper is to characterise the failure model of a system that is covered by a two‐dimensional warranty, one dimension depicting time and the other usage. Specifically, the authors study the effect of use‐rate on system life when each constituent component life...
