Determination of preventive maintenance lead time using hybrid analysis

By Lin Ma, Joseph Mathew, Yong Sun and Sheng Zhang

Abstract

The time for conducting Preventive Maintenance (PM) on an asset is often determined using a predefined alarm limit based on trends of a hazard function. In this paper, the authors propose using both hazard and reliability functions to improve the accuracy of the prediction particularly when the failure characteristic of the asset whole life is modelled using different failure distributions for the different stages of the life of the asset. The proposed method is validated using simulations and case studies
