Maintenance prioritization - a review on factors and methods

Abstract

Purpose: Maintenance is a compulsory cost in any asset's operation and requires sufficient budget to be supported. However, insufficient maintenance allocation would lead to maintenance prioritization being practiced as a solution to relief the maintenance demands. The purpose of this paper is to review and discuss the related literature on the factors considered and methods practiced in maintenance prioritization, especially in asset managements. Design/methodology/approach: A thorough literature search related to factors and methods used in maintenance prioritization was conducted through several journal databases. The keywords maintenance priority, maintenance prioritization, priority management and maintenance planning were used. Publications related to maintenance priority from the period of 1990 to 2016 were reviewed and filtered out. Literature focusing on methods and factors related to maintenance prioritization were analyzed and discussed. Findings: This study presented the trend and publications related to maintenance priority throughout 1990 to 2016. Publications related with methods and factors were analyzed. The most used priority-setting methods include analytical hierarchy process; priority criterion; priority matrix; and failure mode and effect analysis. Factors for maintenance priority were categorized into four categories which are technical, financial, social and political category. A discussion on the strategic direction of maintenance prioritization was conducted to highlight future research and possible improvements. Originality/value: The paper contains a state of the art on publications and discussion related to the factors, methods and suggestions on the strategic aspect of maintenance prioritization. It offers insights and information on the current body of knowledge to academics, researchers, maintenance managers, practitioners and stakeholders concerned with asset management.
