    To manage problems, is to try and cope with a flux of interacting events and ideas which unrolls through time - with the manager trying to improve situations seen as problematical, or at least as less than perfect. The ...
  • On distributed mechatronics controller for omni-directional autonomous guided vehicles 
    Tlale, Nkgatho S. (Emerald, 2006)
    Purpose – In this paper, two omni-directional mobile vehicles are designed and controlled implementing distributed mechatronics controllers. Omni-directionality is the ability of mobile vehicle to move instantaneously in ...
  • On Gaver's parallel system 
    Vanderperre, E.J.; Yadavalli, Venkata S. Sarma; Makhanov, S.S. (Southern African Institute for Industrial Engineering, 2004)
    Gaver’s parallel system (and its variants) has received considerable attention in the literature. The Laplace-transform (LT) of the survival function, corresponding to the underlying systems, has been derived by various ...
  • On some optimisation models in a fuzzy-stochastic environment 
    Luhandjula, M.K.; Joubert, Johan W. (Southern African Institute for Industrial Engineering, 2010-12)
    This paper is on fuzzy stochastic optimisation, an area that is quickly coming to the forefront of mathematical programming under uncertainty. An even stronger motivating factor for the growing interest in this area can ...
  • On the capacitated step-fixed charge and facility location problem : a row perturbation heuristic 
    Oyewole, Gbeminiyi John; Adetunji, Olufemi (Natural Sciences Publishing, 2018-09)
    The Classical Transportation Problem (TP) Tableau which utilizes continuous variable cost has been used to model and solve distribution problems. However, many real distribution problem decisions which require various ...
  • Ontwikkeling van 'n parametriese model vir die sny van ruimtes soos die van margarienbakkies 
    Lubbe, Andre J. (South African Journal of Industrial Engineering, 1990-12)
    When three dimensional machining is performed with a numerically controlled milling machine, then it is necessary to make use of cutter centre point programming because radius correction for these machines is possible in ...
  • The open solution methodology approach to problem solving 
    Janse van Rensburg, Antonie C.; Claasen, S.J. (Schalk Johannes) (Southern African Institute for Industrial Engineering, 1997)
    The Open Solution Methodology is a generic problem solving methodology which is used to solve system related problems through the application of problem solving techniques. The focus of the application of this methodology ...
  • An operational management model for a coal mining production unit 
    Visser, Rene; Claasen, S.J. (Schalk Johannes) (Southern African Institute for Industrial Engineering, 2004)
    The coal mining industry faces increased pressure for higher quality coal at lower cost and increased volumes. To satisfy these requirements the industry needs technically skilled first line supervisors with operational ...
  • An operations research and simulation-based study on improving the efficiency of a slurry drying tower
