  • A two-stage mutation stochastic model of carcinogenesis driven by a two level random environment 
    Yadavalli, Venkata S. Sarma; Udayabaskaran, S.; Pravina, C.T.; Sreelakshmi, S. (IJMEMS, India, 2020)
    In this paper, we present a two-stage stochastic model of carcinogenesis in a two level random environment. The random environment switches between two levels, say, 1 and 2 alternately. When the environment is in level ...
  • Empirical evaluation of a new DEMO modelling tool that facilitates model transformations 
    Gray, Thomas; De Vries, Marne (International Conference on Conceptual Modeling, 2020-11)
    The engineering methodology for organizations (DEMO) incorporates an organization construction diagram (OCD) and transaction product table (TPT) to depict a consolidated representation of the enterprise in terms of ...
  • Activity-based travel demand generation using Bayesian networks 
    Joubert, Johannes Willem; De Waal, Alta (Elsevier, 2020-11)
    While activity-based travel demand generation has improved over the last few decades, the behavioural richness and intuitive interpretation remain challenging. This paper argues that it is essential to understand why people ...
  • Analysis of the jam signal effect against the conical-scan seeker 
    Malatji, Tsholofelo M.; Du Plessis, W.P. (Warren Paul); Willers, Cornelius J. (Society of Photo-optical Instrumentation Engineers, 2019-02)
    There remains a wide proliferation of second-generation frequency-modulated conical-scan seekers in the hands of irregular forces while the understanding of what makes a jam signal effective remains unclear. It is generally ...
  • The moderating effect of industry clockspeed on lean manufacturing implementation in Zimbabwe 
    Maware, Catherine; Adetunji, Olufemi (Emerald, 2019-12)
    PURPOSE : The purpose of this paper is to analyze the moderating impact of industry clockspeed (IC) on the relationship between Lean Manufacturing (LM) practices and operational performance. A model for evaluating the ...
  • Economic order quantity model for growing items with incremental quantity discounts 
    Sebatjane, Makoena; Adetunji, Olufemi (SpringerOpen, 2019-12)
    Certain inventory items are living organisms, for example livestock, and are therefore capable of growing during the replenishment cycle. These items often serve as various saleable food items downstream in supply chains. ...
  • Large expert-curated database for benchmarking document similarity detection in biomedical literature search 
    Brown, Peter; Joubert, Johannes Willem; Zhou, Yaoqi; RELISH Consortium (Oxford University Press, 2019-10)
    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that ...
  • Lean manufacturing implementation in Zimbabwean industries : impact on operational performance 
    Maware, Catherine; Adetunji, Olufemi (Sage, 2019-06)
    The impact of Lean Manufacturing (LM) implementation on organizational performance is an ongoing discussion. The effect of implementing LM tools on operational performance across various industries in Zimbabwe, a country ...
  • Inventory management for growing items in multi-echelon supply chains 
    Sebatjane, Makoena (University of Pretoria, 2020)
    Growing items have, in recent years, emerged as a distinct class of items within inventory modelling, similar to perishable or repairable items, for example. This class of items includes livestock, crops and fish, to name ...
  • Analytical structural model for implementing innovation practices in sustainable food value chain 
    Sharma, Rashi; Darbari, Jyoti Dhingra; Yadavalli, Venkata S. Sarma; Agarwal, Vernika; Jha, P.C. (Springer, 2020)
    In the current scenario, sustainability is asserting a profound effect on the global Food Supply Chain (FSC). It is driven primarily by growing consciousness of consumers who want healthy food and at the same time, they ...
  • Optimal scheduling policy for a multi-upgraded software system under fuzzy environment 
    Anand, Adarsh; Das, Subhrata; Agarwal, Mohini; Yadavalli, Venkata S. Sarma (ITB Journal Publisher, 2019)
    Many reliability growth models related to the concept of multi upgradation have recently been proposed. This concept has helped software developers to develop a competitive edge over competitors by regularly introducing ...
  • Supply chain micro-communities in urban areas 
    Viljoen, N.M. (Nadia); Joubert, Johannes Willem (Elsevier, 2019-01)
    An increase in urban freight transport is inevitable as growing urban populations require more goods, more conveniently. A deeper understanding of the geography and trends of urban freight transport must recognise that it ...
  • Modelling receiver logistics behaviour 
    Bean, Willemiena Lodewika; Joubert, Johannes Willem (Elsevier, 2019)
    There is a need for collaborative urban freight planning and appropriate decision and planning support tools are lacking, resulting in inadequate understanding of how urban freight agents should collaborate and what benefits ...
  • An agent-based evaluation of transit network design 
    Nnene, Obiora A.; Joubert, Johannes Willem; Zuidgeest, Mark H.P. (Elsevier, 2019)
    This article presents the design and evaluation of transit networks using a route expansion heuristic and agent-based travel demand simulation. The route expansion mechanism is a type of constructive heuristic algorithm ...
  • Having a crack at bottle scuffing using agent-based mobility 
    Dempers, Clemens A.; Joubert, Johannes Willem (Elsevier, 2019)
    Recent advances in large-scale mobility models have shown that much system-level insight can be gained when modelling at the disaggregate, individual level. Although the focus is often on the movement of vehicles and/or ...
  • Using MATSim to test sensitivity towards vehicle ban enforcement 
    Joubert, Johannes Willem (Elsevier, 2019)
    In recent years many authorities have considered heavy vehicle restrictions, or complete bans, in certain parts of the city to alleviate both congestion and other externalities. But such restrictions are often implemented ...
  • Solving the buffer allocation problem using simulation-based optimisation 
    Kotze, Dirk Jacobus (University of Pretoria, 2020-01-14)
    This dissertation solves the BAP, using SBO. Chapter 1 describes the role buffers play within a production line. Buffer is allocated to decouple stations and reduce the effect station failure and differing process times ...
  • Modelling rhino presence with Bayesian networks 
    Van der Laarse, Maryn (University of Pretoria, 2020)
    Modelling complex systems such as how the white rhinoceros Ceratotherium simum simum uses a landscape requires innovative and multi-disciplinary approaches. Bayesian networks have been shown to provide a dynamic, easily ...
