n South African Journal of Industrial Engineering - An integrated systems approach to risk management within a technology-driven industry, using the design structure matrix and fuzzy logic : case study




Risk interactions exist within a system and its sub-systems, between functional and physical elements in various dimensions such as spatial interaction, information exchange, material transfer, and energy exchange. These interactions are of a multi-dimensional complexity, and thus are not sufficiently interpreted using conventional management tools. Alternative system representation and analysis techniques are proposed - in particular the design structure matrix (DSM) and fuzzy logic thinking - to quantify the risk management effort necessary to deal with uncertain and imprecise interactions. A cement grinding plant case study is used to elaborate on the risk management methodology.

Risiko-interaksies bestaan binne 'n stelsel en sy sub-stelsels, tussen funksionele en fisiese elemente. Hierdie interaksies kan gekwantifiseer word in 'n ruimtelike, inligting-uitruiling, materiaal-oordrag of energie-uitruiling raamwerk. Die interaksies is van 'n multi-dimensionele kompleksiteit, en word nie effektief geïnterpreteer deur middel van konvensionele beheermetodes nie. Alternatiewe stelselvoorstelling- en analiseringstegnieke kan gebruik word om die sisteeminteraksies te visualiseer. Die Ontwerp Struktuur Matriks ('design structure matrix'), en Wasige Logika ('Fuzzy Logic') word ingespan om hierdie interaksies voor te stel en eenvoudig te kwantifiseer. 'n Sementaanleggevallestudie word gebruik om die risikobestuurmetodologie op die proef te stel.
