MAINTENANCE PERFORMANCE RESEARCH – PART 1: A REVIEW OF MODELS AND ISSUES

<p>ENGLISH ABSTRACT: The paper presents a comprehensive review of maintenance performance research. Articles on general surveys, system modelling, and specific applications in industries are reviewed. The scientific principles underlying maintenance performance research for the past 30 years are considered. The body of knowledge on maintenance performance is both quantitatively and qualitatively based. Of the quantitative approaches are economic and technical ratios, value-based and balanced scorecard, system audit, strategic, composite formulation, statistical, and partial maintenance productivity indices. The qualitative approaches include Luck's method, among others. Qualitative-based approaches are adopted in view of the inherent limitations of measuring a complex function such as maintenance effectively through quantitative models. Maintenance decision makers often come to the best conclusion using heuristics, backed up by qualitative assessment, supported by quantitative measures.</p><p>AFRIKAANSE OPSOMMING: Die artikel lewer ‘n omvattende oorsig van navorsing oor instandhouding. ‘n Aantal artikels oor algemene opnames, sisteemmodellering en nywerheidstoepassings word behandel. Die beginsels en praktyk van instandhoudingsvertoning moet deeglik verstaan word voordat die leser poog om navorsingsbronne ten beste te kan benut. Die versamelde kennis oor instandhoudingsvertoning is gebaseer op kwantitatiewe en kwalitatiewe beginsels. Die spektrum van kwantitatiewe metodes is uitgebreid en uiteenlopend. Die kwalitatiewe metodes word ook betrek om die kompleksiteit van instandhoudingsvraagstukke te behandel. Dit is dikwels so dat besluitvormers die beste oplossings vind op grond van heuristiese metodes gebaseer op kwalitatiewe en kwantitatiewe beskouings.</p&gt
