Using AHP Methods in Maintenance to Improve Reliability and Equipment Performance

Abstract

The engineers are usually expected to consider several influential criteria when selecting as a single best alternative for water maintenance system (WMS). This research discusses the approach based on the Analytic Hierarchy Process (AHP) as a decision making tool for selecting WMS. Supported with information of equipment breakdown, the questionnaire method as well as personal interviews as a main tool to collect data and information in the practical aspect of the study. In this study, the AHP decision support tool was applied in a maintenance systems field in the town of AL- Fallujah Water Treatment Project, Iraq. The AHP was applied to evaluate and an alternative is chosen from a set of maintenance alternatives: [ Preventive Maintenance (M1), Proactive Maintenance (M2), Total Productive Maintenance (M3), Predictive maintenance (M4) and Corrective Maintenance (M5)] vs eight of Maintenance pillars. Results indicate the advantages over traditional Decision Making selection methods. By using this information with AHP the best rank of alternatives was M3(11.85), M4(9.67) and so on. Moreover, the relationship between M3 and the pillars of maintenance: indicates a very high correlation 78%. The study reached a number of conclusions, the most important of which is the existing of a very strong impact for the proposed maintenance system in improving the performance and reliability of FWTP project operations.
