Maintenance philosophy

Maintenance philosophy refers to a set of principles and guidelines that dictate the organization and execution of maintenance activities. It is a high-level description of the overall principles for maintenance management. There are different types of maintenance philosophies, including preventative-based maintenance, which aims to repair a component before failure, and can be broken down into two subcategories: calendar-based maintenance or condition-based maintenance.From: Reliability, Risk, and Safety, Three Volume Set [2019], Condition monitoring systems: a systematic literature review on machine-learning methods improving offshore-wind turbine operational management [2021]

Most industrial assets are complex repairable systems. Maintenance decisions are still made based on the experience and understanding of the maintenance engineers/managers. This leads to sub-optimal decisions and inefficient and ineffective maintenance. Reliability is a key attribute of such assets. Reliability-centered maintenance (RCM) as a maintenance philosophy and reliability engineering as an engineering discipline have been well developed over the past several decades.

In contrast, the preventative-based maintenance philosophy aims to repair a component before failure, this is broken into two subcategories: calendar-based maintenance or condition-based maintenance. Calendar-based maintenance is performed by annual or semi-annual visits or scheduled replacements based on the operational life of the component. A more effective approach is condition-based maintenance, where the components are repaired based on the health of the part. This strategy aims to predict failure before it occurs so that the scheduling can be planed earlier in a corrective manner to reduce downtime. Producing accurate predictions of the remaining useful life of an asset is a complex task, especially so in a complex system with multiple failure modes.
