  • A model to optimize payloads at PFG Building Glass 
    Brits, R.; Conradie, Pieter J. (Southern African Institute for Industrial Engineering, 2003)
    While improving customer service by allowing user definable mixed load orders of their plate glass product, PFG Building Glass was confronted with a problem of calculating the feasibility and optimum load layout for ...
  • 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 ...
  • A perishable product inventory system operating in a random environment 
    Yadavalli, Venkata S. Sarma; Van Schoor, Christiaan de Wet (Southern African Institute for Industrial Engineering, 2004)
    A model of a perishable product inventory system operating in a random environment is studied. For the sake of simplicity, the stochastic environment is considered to alternate randomly over time between two states 0 and ...
  • The design of a simulation generator 
    Janse van Rensburg, Antonie C. (Southern African Institute for Industrial Engineering, 1993-12)
    Successful simulation studies depend on a variety of expertise such as statistics, computer programming, systems analysis and design techniques. Unfortunately these requirements limit the availability of competent simulation ...
  • Optimisering van logistieke steun 
    Claasen, S.J. (Schalk Johannes) (Southern African Institute for Industrial Engineering, 1992-06)
    Die verwantskap tussen stelselprestasie en die omvang van logistieke steun wat 'n stelsel ontvang, word kortliks bespreek. 'n Teoretiese optimum vlak van logistieke steun word gedetinieer en daar word getoon dat die ...
  • The concept of age in systems analysis 
    Dubi, A.; Gurvitz, N.; Claasen, S.J. (Schalk Johannes) (Southern African Institute for Industrial Engineering, 1993-12)
    This paper discusses the mathematical concept of ageing. It is shown that while in most cases a probabilistic definition of age is sufficient, in some cases a calendaric definition must be added in order to preserve the ...
  • A framework for the implementation of e-procurement 
    Jooste, M.V.; Van Schoor, Christiaan de Wet (Southern African Institute for Industrial Engineering, 2003)
    e-Procurement is a sound solution for companies to initiate e-business initiatives since it promises several distinct benefits, such as process cost and lead time reduction, improving strategic sourcing of commodities and ...
  • Betroubaarheids-, beskikbaarheids- en logistieke steunanalise 
    Claasen, S.J. (Schalk Johannes) (Southern African Institute for Industrial Engineering, 1991-06)
    AMIR en SPAR is Monte Carlo-gebaseerde rekenaarprogrammatuur waarmee betekenisvolle analise ten opsigte van die betroubaarheid, beskikbaarheid en logistieke steunbaarheid van komplekse stelsels uitgevoer kan word. Dit ...
  • Mathematical basis for three dimensional circular interpolation on CNC machines 
    Lubbe, Andre J. (Southern African Institute for Industrial Engineering, 1997)
    The control units of numerically controlled manufacturing machines allow the programmer only a limited number of mathematical functions with which programmes can be written. Despite these limitations it is now possible ...
  • The development of a laser based local positioning system 
    Lubbe, Andre J.; Buhrmann, T. (Southern African Institute for Industrial Engineering, 2001)
    There is no cheap, accurate device available with which the position of a slow moving object , such as a lawnmower cutting lawn, can be determined. If such a positioning system were available it would be possible to ...
  • The development of a computer driver jigsaw 
    Lubbe, Andre J.; Raath, H. (Southern African Institute for Industrial Engineering, 2003)
    With a jigsaw, sharp inside corners can only be sawn out if the blade of the jigsaw is lifted out of the material and the corner is approached from two different sides. For the blade to be able to re-enter the material no ...
  • Jumping the curve 
    Pellissier, Rene; Kruger, P.S. (Paul Stephanus), 1944- (Southern African Institute for Industrial Engineering, 1999)
    This paper explores the notion of jumping the curve,following from Handy 's S-curve onto a new curve with new rules policies and procedures. It claims that the curve does not generally lie in wait but has to be invented ...
  • Praktiese driedimensionele sirkel-interpolasie vir numeriesbeheerde masjiene 
    Lubbe, Andre J. (Southern African Institute for Industrial Engineering, 1992-12)
    Numerically controlled manufacturing machines provide for machining circles only in two dimensions. As a result of this limitation a wide variety of shapes can only be machined by making use of computer-aided design. ...
  • Beyond re-engineering: de-engineering the corporation 
    Pellissier, Rene; Kruger, P.S. (Paul Stephanus), 1944- (Southern African Institute for Industrial Engineering, 2000)
