Department of Decision Sciences


The Department of Decision Sciences remains, together with the other departments of the School of Economic and Financial Sciences, at the forefront of research in the College of Economic and Management Sciences. The research done in the Department reflects the interdisciplinary approach typical of operations research and related subjects.

Research groups

Although a considerable amount of research is conducted in staff members' personal capacity, the following groups operate in the Department.

  • Computability and Complexity in Decision Sciences (CCDS)

The research group Computability and Complexity in Decision Sciences (CCDS) at the University of South Africa (Unisa) in Pretoria is one of South Africa’s pre-eminent centres for research in theoretical computer science (including foundations of quantum computing) as well as being at the forefront of research into computational and fractal properties of sample paths of Brownian motion (BM) and images of sets under BM. The group has also investigated computational and constructive aspects of economic models and was the main South African partner in a project funded under the South Africa-Hungary Science and Technology Agreement (NRF UID: 62110) entitled Computers and Algorithms in Mathematical Economics and Finance.  The group currently participates in the Computing with Infinite Data project, funded by the European Union.

  • Research Group in Modelling and Optimisation

The main focus of the group is on modelling, algorithmic and practical aspects of optimization. It also aims at exposing itself to wide frontiers in the field of mathematical programming and to meet new challenges Optimization Theory has in the overlap of several disciplines. The group seeks to strike an optimal balance between contributing to the progress of knowledge and increasing of the value of research outcomes by applying them to solving, effectively and efficiently, concrete real life problems.

  • Quantum Information and Computation (QuIC) Research Group

The Unisa QuIC group has been active for several years, and has collaborated on research problems to do with the universality and programmability of quantum computers, as well as other related topics. The work is truly multi-, inter and trans-disciplinary (MIT), straddling the disciplines of quantum physics, computer science and mathematics and engineering.

  • Tuition Reflexive Research Workgroup

The Decision Sciences Tuition Reflexive Research Workgroup focuses on projects related to the improvement of the tuition efforts of the Department.

  • Publications and research outputs

Information about Publications are available under staff members' personal pages.
