A SYSTEMATIC SURVEY OF THE MAINTENANCE MODELS

Abstract

A systematic survey of the maintenance models has been carried out, which may help the maintenance engineer to have a total picture on maintenance policies. Maintenance policies dis- cussed in the literature have been studied, inter-related and classified into three groups viz. (I) Re- placement/repair at failure, (II) Planned maintenance (repair/replacement) at pre-determined intervals based on number of failures or otherwise and (Ill) Condition based maintenance. The above number of groups are necessary and sufficient for the purpose of methodical surveying of the publications on the topic.
