Simulation-based optimization for decision making under uncertainty in opencast mines
1. The complex interaction between the objectives, all mining elements, and the deposit model does not allow for a closed form optimization problem to be formulated. Hence, existing methods tend to oversimplify the dynamics and the stochasticity of the real system. (Dissertation) 2. In continuous coal mining operations, geological uncertainty does not only affect the quality/amount of coal produced, but also affects over and inter-burden management and delays dispatching. (Dissertation) 3.
... ssertation) 3. Simulation techniques, including geostatistical simulation and discrete-event simulation (DES), can be effectively used for decision support in any mining operation. (Dissertation) 4. The Simulation-based Optimization approach leads to significant reductions in downtimes of equipment. (Dissertation) 5. The focus of mining scholars should be on the development of efficient algorithms for the optimization of short-term production scheduling rather than long-term production planning. 6. The traditional Discounted Cash Flow (DCF) valuation method must be replaced by the Real Option Valuation (ROV) method for the calculation of Net Present Value (NPV) of mining projects. 7. PhD Students should not be judged based on their short-term performances, but the long-term achievements. 8. Every PhD Student must be an independent thinker and must not be bound to any limiting constraints. 9. Programmers should first develop their communications skills and then a code.
