Abstract


A state of Maintenance Excellence is when an  organisation  has achieved best maintenance practice standards and has reached the benchmark  for the performance of maintenance operations.  Various models  exist in literature  that highlight what elements need to be present in an organization  in order to achieve maintenance excellence  standards.  However, these standards have to be  prioritised  according to the current state of the  organisation’s operations. The Analytic Hierarchy Process (AHP) is a technique that is useful in establishing the priority and importance of individual decision-making alternatives through pairwise comparisons. In this study, the AHP process is used to evaluate a set of  organisation-specific maintenance excellence criteria. A railway rolling stock maintenance  organisation  in the Western  Cape region of South Africa is  used as a case study for this exercise.  By  applying AHP to the results obtained from a survey conducted at the case study, some inconsistencies were found in the  judgments  made  by the respondents. AHP was then used again to revise these judgments to make them more consistent.  The end result of the study was  a set of weighted and  prioritized  maintenance excellence criteria which will be useful in the organization’s endeavors to attain maintenance excellence.
