  • Bayesian energy measurement and verification analysis 
    Carstens, Herman; Xia, Xiaohua; Yadavalli, Venkata S. Sarma (MDPI Publishing, 2018)
    Energy Measurement and Verification (M&V) aims to make inferences about the savings achieved in energy projects, given the data and other information at hand. Traditionally, a frequentist approach has been used to quantify ...
  • Bayesian structural time-series approach to a long-term electricity demand forecasting 
    Mokilane, Paul; Debba, Pravesh; Yadavalli, Venkata S. Sarma; Sigauke, Caston (Natural Sciences Publishing, 2019-03)
    The paper presents an application of Bayesian structural time-series model to forecast long-term electricity demand. Accurate trend specification in long-term forecasting is important; otherwise erroneous forecasts could ...
  • Behavioural sensitivity towards emission concepts 
    Grabe, Ruan Johannes; Joubert, Johan W. (Elsevier, 2021)
    Agent-based simulation lends itself to study emergent behaviour when agents respond autonomously, based on their unique and individual attributes, to external interventions. In transport, the vehicle-specific attribute ...
  • Benchmark dataset for undirected and mixed capacitated arc routing problems under time restrictions with intermediate facilities 
    Willemse, Elias J.; Joubert, Johannes Willem (Elsevier, 2016-07)
    In this article we present benchmark datasets for the Mixed Capacitated Arc Routing Problem under Time restrictions with Intermediate Facilities (MCARPTIF). The problem is a generalisation of the Capacitated Arc Routing ...
  • Betroubaarheids- en instandhoubaarheidstoedeling 
    Lottering, W.A.; Claasen, S.J. (Schalk Johannes) (Southern African Institute for Industrial Engineering, 1988-12)
    Ontwerpdoelwitte vir die betroubaarheid an instandhoubaarheid van substelsels moet so bepaal word dat die gebruikersvereiste ten opsigte van betroubaarheid en instandhoubaarheid van die stelsel behaal word as substelseldoelwitte ...
  • 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 ...
  • Beyond re-engineering: de-engineering the corporation 
    Pellissier, Rene; Kruger, P.S. (Paul Stephanus), 1944- (Southern African Institute for Industrial Engineering, 2000)
    This paper addresses the failure of re-engineering to deliver its promise of better organizational performance through radical change. It looks at the change in Hammer and Champy's own perceptions of what re-engineering ...
  • Business design in the enterprise life-cycle 
    Rottier, Johan; Kruger, P.S. (Paul Stephanus), 1944-; Pretorius, Pieter J. (Southern African Institute for Industrial Engineering, 2001)
    The purpose of this paper is to facilitate systematic management of the design of Enterprises throughout their life-cycle by identifying the events (requirements) which should initiate (re)design. It identifies the high ...
  • Business process re-engineering and agile software development : applying the story-card method 
    Djan, Elijah Kwaku Addae Gyedu; De Vries, Marne (Springer, 2020-04)
    Enterprise designers need to continuously re-design their enterprise, re-evaluating the technologies that are available to digitize their operations. Although light-weight agile software development approaches are favored ...
  • Can complexity analysis support business performance insight? 
    Janse van Rensburg, Antonie C. (Southern African Institute for Industrial Engineering, 2012-07)
    Most people intuitively understand complexity, but being able to analyse it scientifically is not a common practice. For business executives, ‘complexity’ must be one of the most important concepts to understand, as it ...
  • A case study on inter-organisational technology transfer in the defence industry 
    Bezuidenhout, Saija; Bean, Willemiena Lodewika (Emerald, 2022-02)
    PURPOSE : This paper aims to establish a systematically constructed defence offset technology transfer (TT) process description and to identify the process pain points and critical success factors from the supplier ...
  • Centrifugal separation experimentation and optimum predictive model development for copper recovery from waste copper smelter dust 
    Okanigbe, Daniel; Olawale, Popoola; Popoola, Abimbola; Adeleke, Abraham; Ayomoh, Michael Kweneojo; Kolesnikov, Andrei (Cogent OA, 2018)
    This research has presented a three level-two factors full factorial experimental design that investigated the process parameterization of a centrifugal concentrator for the separation of a waste copper smelter dust ...
  • Combining accelerometer data and contextual variables to evaluate the risk of driver behaviour 
    Joubert, Johannes Willem; De Beer, Dirk Johannes; De Koker, Nico (Elsevier, 2016-08)
    Telemetry devices are generating and transferring increasingly more data, with notable potential for decision makers. In this paper we consider the accelerometer and speed data produced by in-vehicle data recorders as a ...
  • A comparative review of the complementary and conflicting nature of lean production and green manufacturing implementation 
    Machingura, Tinotenda; Adetunji, Olufemi; Maware, Catherine (Emerald, 2024)

  • A comparative study of artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) models in distribution system with nondeterministic inputs 
    Okwu, Modestus O.; Adetunji, Olufemi (SAGE Publications, 2018)
    Most deterministic optimization models use average values of nondeterministic variables as their inputs. It is, therefore, expected that a model that can accept the distribution of a random variable, while this may involve ...
  • Complex network approach to understand commercial vehicle movement
