  • Parametric optimization and statistical evaluation of a spray dryer for the evaporation of caustic soda solution 
    Olufemi, B.A.; Ayomoh, Michael Kweneojo (Elsevier, 2019-07)
    Optimum evaporation of a 50% w/w caustic soda solution with a spray dryer was investigated in this work to enhance performance and statistically evaluate process parameters. Application of suitable model with validation ...
  • A people-centred view on paratransit in South Africa 
    Woolf, S.E.; Joubert, Johan W. (Elsevier, 2013-12)
    Paratransit provides a valuable service offering as a flexible and substitutional mode between formal transit and private car. When it evolves to compete with more formal transit modes, efforts are made to formalise it. ...
  • Performance evaluation of the supply chain system of a food product manufacturing system using a questionnaire-based approach 
    Makinde, Olasumbo; Mowandi, Tebogo; Munyai, Thomas; Ayomoh, Michael Kweneojo (Elsevier, 2020)
    Effective management of the end-to-end process of a food industry is vital for the achievement of the key strategic objectives of this organisation. However, various factors have limited the performance and productivity ...
  • 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 ...
  • Phase‐conjugating retrodirective cross‐eye jamming 
    Du Plessis, W.P. (Warren Paul) (Wiley Open Access, 2020-09)
    A cross‐eye jammer based on a phase‐conjugating (PC) retrodirective array is proposed. Such PC cross‐eye jammers eliminate the delay inherent in traditional Van‐Atta (VA) cross‐eye jammers and induce errors in radars that ...
  • The philosophy-tool continuum: providing structure to Industrial engineering concepts 
    Van Dyk, Liezl (Southern African Institute for Industrial Engineering, 2001)
    Industrial Engineering concepts are often referred to as either a tool, technique, method, approach or philosophy. These terminologies can be positioned on a continuum according to their meaning as defined by the Oxford ...
  • Planning empty container relocations under uncertainty 
    Bean, Willemiena Lodewika; Joubert, Johan W. (Southern African Institute for Industrial Engineering, 2010-05)
    Reusable packaging often accumulates downstream in supply chains, resulting in non-revenue-earning relocations. This paper presents a reliable optimisation model under supply and demand uncertainty. Instead of using ...
  • The power of one : Benford's law 
    Kruger, P.S. (Paul Stephanus), 1944-; Yadavalli, Venkata S. Sarma (Southern African Institute for Industrial Engineering, 2017-08-31)
    The concept of Benford’s law, also known as the first-digit phenomenon, has been known to mathematicians since 1881. It is counter-intuitive, difficult to explain in simple terms, and has suffered from being described ...
  • 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. ...
  • Privacy-preserving data mining of cross-border financial flows 
    Sekgoka, Chaka Patrick; Yadavalli, Venkata S. Sarma; Adetunji, Olufemi (Cogent OA, 2022)
    Criminal networks continue to utilize the global financial system to launder their proceeds of crime, despite the broad enactment of anti-money laundering (aml) laws and regulations in many countries. Money laundering ...
  • Probability management and the flaw-of-averages 
    Kruger, P.S. (Paul Stephanus), 1944-; Yadavalli, Venkata S. Sarma (Southern African Institute for Industrial Engineering, 2016-12-06)
    Uncertainty is ever-present and is an integral part of life. Recognising the existence of uncertainty and its possible effects on decision-making may be important for the profitability, financial success, or even survival ...
  • Production mix problems : formulation and solution strategies 
    Warren, Graeme (Southern African Institute for Industrial Engineering, 2001)
    This paper examines the sub-optimality of generalized greedy heuristics for solution of a certain well-known production mix problem formulation. The drawbacks of not modelling routing in the mix problem formulation are ...
  • Proposed business process improvement model with integrated customer experience management 
    Botha, G.J. (Gesina Jozina); Janse van Rensburg, Antonie C. (Southern African Institute for Industrial Engineering, 2010-05)
    In these modern times it is more and more difficult to become and stay competitive in the business environment. Customers have increasingly more products to choose from and more channels through which they can satisfy their ...
  • Quality systems in the fresh fruit export industry 
    Netterville, R.; Adendorff, Kris (Kristian) (Southern African Institute for Industrial Engineering, 2002)
    The fresh fruit export industry has traditionally relied heavily on end point inspection to achieve quality. In response to several changes in international markets and concerns over the inability of end point inspection ...
