Assessing the impact of new technology on complex sociotechnical systems

Author: Oosthuizen, Rudolph ; Pretorius, L Date: Aug 2016 In complex sociotechnical systems, cognitive and social humans use technology to make sense of situations for decisions. These elements make sociotechnical systems difficult to develop. A modelling and assessment methodology for systems ... Read more
Assessment methodology for air defence control systems

Author: Oosthuizen, Rudolph Date: Sep 2013 In Command and Control, humans have to make sense of the situation to support decision making on the required action. Development of an Air Defence Control system through a Systems Engineering process starts with assessment of existing systems ... Read more
Bibliometric analysis of technology management research topic trends

Author: Oosthuizen, Rudolph ; Pretorius, L Date: Sep 2020 Published research is a good indicator on the trends and maturity of a scientific discipline. Bibliometric analysis is a valuable tool to assess published research. Since Technology Management is still a growing discipline, it requires a ... Read more
A bibliometric approach to support redefining management of technology for the post-digital world

Author: Oosthuizen, Rudolph Date: Sep 2021 Management of Technology (MoT) has evolved since its inception in the 1980s and definitions from the 1990s. However, the field's definition may not be keeping up with the ever-increasing changes in our world. This paper implements bibliometrics, ... Read more
A bibliometric method for analysis of systems engineering research

Author: Oosthuizen, Rudolph ; Pretorius, L Date: Jul 2020 Since systems engineering is still a relatively young and growing discipline, it requires a periodic analysis, taking into account past research to derive the requirements for future growth. Published research provides a good indication on ... Read more
Boundary management and integration framework for a joint cyber defence capability for military forces: analysis and synthesis from a through-life capability management perspective

Author: Roodt, JHS ; Oosthuizen, Rudolph ; Jansen van Vuuren, JC Date: Apr 2010 This investigation was launched firstly to direct current Information Warfare definition and capability management activities toward establishing a Require Operational Capability (ROC) statement for a JCD capability, and secondly to provide ...

Credible defence capability: command and control at the core

Author: Oosthuizen, Rudolph ; Roodt, JHS Date: Oct 2008 In the acquisition environment, smart systems and equipment represent the tip of the proverbial iceberg – it takes much more to realise a credible defence capability, that is, one that comprises all components of a user system to enable a ... Read more
Cyber security investment cost-benefit investigation using system dynamics modelling

Author: Oosthuizen, Rudolph ; Pretorius, L ; Mouton, Francois ; Molekoa, Malinkeng M Date: Feb 2019 As cyber-attacks pose a major threat to organisations, security measures are required to protect networks and information. Defence against these attacks requires substantial resources and investments from organisations. The level of perceived ... Read more
Describing joint air defence within operations other than war context as a complex system

Author: Oosthuizen, Rudolph Date: Oct 2009 The objective of Joint Air Defence (JAD) is to defend own assets against all types of hostile aerial attack. This may even happen within the context of Operations Other Than War (OOTW). Like general warfare, OOTW is a complex environment where ... Read more
Design of the M&S acquisition support effort of the SANDF GBADS acquisition programme

Author: Nel, JJ ; Roodt, JH ; Oosthuizen, Rudolph Date: Jun 2007 The Ground Based Air Defence System (GBADS) acquisition programme, of the South African National Defence Force (SANDF), provided an opportunity to apply Modelling and Simulation (M&S), at a system of systems level, for acquisition risk ... Read more
Establishing a methodology to develop complex sociotechnical systems

Author: Oosthuizen, Rudolph ; Pretorius, L Date: Feb 2013 Many modern management systems, such as military command and control, tend to be large and highly interconnected sociotechnical systems operating in a complex environment. Successful development, assessment and implementation of these systems ... Read more
A framework for implementing a data science capability in a military intelligence system

Author: Van 't Wout, Magdalena C ; Ball, Shaun V ; Oosthuizen, Rudolph Date: Oct 2019 Modern day conflicts give rise to complex problems that traditional military intelligence approaches and tools struggle to resolve. There is a need for prediction and/or forecasting in the military domain based on effective intelligence ... Read more
Framework to investigate emergence in system engineering

Author: Oosthuizen, Rudolph ; Roodt, JH ; Pretorius, L Date: Sep 2011 System Engineering is the process of identifying, implementing and maintaining solutions to real world problems. Some problems tend to be messy with no single solution or set of effective and accurate requirements, often resulting in ... Read more
Implementing bibliometric analysis and topic modelling to inform curriculum development for engineering management

Author: Oosthuizen, Rudolph ; Grobbelaar, S Date: Oct 2021 This paper aims to inform the course curriculum development for a master's degree in Engineering Management. Implementing a bibliometric analysis with topic modelling performed on relevant publications in the field ... Read more
Implementing model based systems engineering in South Africa

Author: Oosthuizen, Rudolph Date: Oct 2017 In Systems Engineering (SE), modelling is applied to capture and represent the mental models of the systems’ stakeholders. These models, consisting of various viewpoints on the system structure and behavior, can be used to derive requirements ... Read more
Implementing UPDM to develop command and control systems

Author: Oosthuizen, Rudolph ; Venter, C Date: Sep 2016 Systems engineering is an established approach to develop systems, including complex sociotechnical systems such as Command and Control (C2) Systems.
