Optimal resource allocation in Virtual Network Embedding
(North-West University (South Africa), 2019)
Optimal resource allocation has become a focus in the technological environment due to the high costs associated with physical infrastructure and space. Furthermore, Network Operators (NO)s have to keep up with the rate ...
Developing a digital twin for addressing complex mine ventilation problems
(North-West University (South Africa), 2021)
The ventilation system of a deep-level mine is complex and dynamic, which makes it challenging to identify changes in such a system and even more so to predict the effect of these changes with conventional approaches. An ...
Optimisation of mine secondary fan systems
(North-West University (South Africa)., 2020)
The rising cost of electricity in South Africa has driven deep-level gold mines to save on costs. The optimisation of mine ventilation systems has shown significant potential for energy savings. A literature study showed ...
Mine ventilation characterisation through simulations
(North-West University, 2018)
The profitability of the mining industry is contingent on the industry’s ability to improve upon the status quo of operational efficiency. If the archaic operating methods of mines are altered to embrace and incorporate ...
Performance optimisation of vertical spindle coal pulverisers
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Coal pulverisers’ performance optimisation is an important process in power generation plants. Pulveriser operation is costly; reliability and availability is key to power generation and cost reduction is achieved by the ...
Incremental FTTH deployment planning
(North-West University (South Africa) , Potchefstroom Campus, 2016)
The use of optical fibres is favoured due to its desirable physical properties and especially
for its high bandwidth transmission capability. The challenges faced in the
design of fibre-based networks, specifically FTTH ...
Improving energy cost performance of steel production mills
(North-West University, 2018)
The global steel supply capacity is more than the demand. This has caused an increase in competition and imports to some countries. South Africa is one of the affected countries and the effects have been seen in the closing ...
Exact approaches towards solving generator maintenance scheduling problems
(North-West University (South Africa), 2019)
The holistic management of a national power system is faced with multiple long and short-term scheduling challenges. One of the key long-term scheduling problems is referred to as the generator maintenance scheduling problem ...
Resource allocation and scheduling within the context of fibre network deployment
(North-West University (South Africa), 2019)
The Resource-constrained Project Scheduling Problem (RCPSP), where a schedule must obey the resource constraints and precedence constraints of various activities over time, is one of the most studied scheduling problems. ...
Development of a lean optimisation plan for a wire manufacturing process
(North-West University (South Africa), 2019)
The growing demand for maximum operational efficiency has driven organisations towards implementing lean manufacturing as a management philosophy. However, a gap still exists between the available information on lean ...
