    Conradie, D.G.; Joubert, Johan W. (Southern African Institute for Industrial Engineering, 2004-11)
    Operations Research is perceived to be on the verge of demise as a decision support tool in industry. However, this is not true, since the relevancy and interdisciplinary nature of Operations Research makes it an indispensable ...
  • Evaluating or selecting a suitable information system development methodology : a case study 
    De Vries, Marne (Southern African Institute for Industrial Engineering, 2004-11)
    Information system development methodologies have been applied by numerous organisations since the mid-1980s in an attempt to improve the efficiency and effectiveness of designing and developing new information systems. ...
  • Stochastic model for common cause failures and human error 
    Yadavalli, Venkata S. Sarma; Bekker, Andriette, 1958- (Southern African Institute for Industrial Engineering, 2005-05)
    A consistent asymptotic normal (CAN) estimator and confidence limits for the steady-state availability of series and parallel systems subject to unit failures, common-cause shock (CCS)failures and human error are studied. ...
  • Distributed control architecture of an omni-directional autonomous guided vehicle 
    Tlale, Nkgatho S. (Southern African Institute for Industrial Engineering, 2005-11)
    Omni-directionality is the ability of a mobile robot to move instantaneously in any direction. This paper describes the wheel and controller designs of a Mecanumwheeled, autonomous guided vehicle (AGV) for reconfigurable ...
