Assessment of the national DSM potential in mine underground services
(North-West University, 2003)ESKOM is moving towards a price structure for electricity which reflects, as far as possible, the real cost of generation. It is called real time pricing (RTP). ESKOM developed this cost structure to coax customers to ... -
A column generation approach for product targeting optimisation within the banking industry
(North-West University (South Africa)., 2023-10)Product targeting optimisation within the financial sector is becoming increasingly complex as optimisation models are exposed to an abundance of data-driven analytics and insights generated from a host of customer ... -
Decongestion of the distribution grid via optimised location of PV-battery systems
(IET, 2017)In order to achieve the energy targets for 2020, further integration of renewable energy sources is required. Hence, there was a need to investigate possible solutions to achieve a reliable network without loss of production. ... -
Design and optimisation of a solar thermal powered Aqua-Ammonia diffusion-absorption heat pump cycle under seasonal variance for residential use
(North-West University (South Africa)., 2021)The diffusion-absorption refrigerator was patented by Von Platen and Munters (1926). The conventionally low coefficient of performance and the high driving temperature have been the focus of most research since its ... -
Design optimisation and experimental evaluation of a grain vibration screen
(2016)Mechanical screening is an important process which is used in a wide range of industries. This study focused on screens in the agricultural industry used for cleaning and classifying of grain. Mathematical models were ... -
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 ... -
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 ... -
An energy efficient mass transportation model for Gauteng
(North-West University, 2011)Public transportation in South Africa is characterized by little or no consideration for energy efficiency and use of cleaner fuels. In the case of transport planning in South African cities, no assessment of the economic ... -
Evaluating complex mine ventilation operational changes through simulations
(Univ Cape Town, 2018)Increasing the profitability of the mining industry is contingent on its ability to improve operational efficiency. Mine ventilation networks typically represent 25-50% of a mine’s energy consumption and, therefore, ... -
Evaluation of sub- and supercritical Rankine cycle optimisation criteria
(North-West University (South Africa) , Potchefstroom Campus, 2017)The main purpose for this study has been to model an advanced real Rankine cycle for sub and super-critical boilers with all the components as encountered in the industry mathematically and to optimise each cycle. First ...
