Reliability and spare parts estimation considering operational environments: a case study
2012 (English)Conference paper, Presentation (Refereed)
Spare parts provision is a complex problem andrequires an accurate model to analysis all factors that mayaffect the required number of spare parts. The number ofspare parts required can be effectively estimated based onthe reliability performance of the item. The reliabilitycharacteristics of an item are influenced not only by theoperating time, but also by factors such as the operationalenvironment. Therefore, for spare parts provisioning to beeffective, the impact of these influence factors on thereliability performance of the item should be quantified.Hence, the statistical approach selected for reliabilityperformance analysis must be able to handle the effect ofthese factors. One of the important models for reliabilityperformance analysis that takes influence factors intoaccount is the proportional hazard model (PHM), which hasreceived less attention in the field of spare partsprovisioning. In this paper the application of PHM to spareparts provision is discussed and demonstrated by a casestudy.
