Comparison of Multi Criteria Decision Making Methods From The Maintenance Alternative Selection Perspective

--------------------------------------------------------ABSTRACT----------------------------------------------------------The significance of decision making from the maintenance perspective has long been acknowledged by the manufacturing industry. Appropriate maintenance alternative decision making increases machine reliability and enhances both productivity and product quality. By contrast, poor decision making disrupts production and increases production costs. Thus, different multi-criteria decision making (MCDM) methods were developed and implemented in the maintenance alternative decision making process. This paper reviewed and compared the application of four popular MCDM techniques in maintenance decision making. The methods included analytic hierarchy process, elimination and choice expressing reality, simple additive weighting, and technique for order preference by similarity to ideal solution. The comparisons were based on the aspects of consistency, problem structure, concept, core process, and accuracy of final results.
