Robust production scheduling in open-pit mining under uncertainty: a box counterpart approach
Open-Pit Production Scheduling (OPPS) problem focuses on determining a block sequencing and scheduling to maximize Net Present Value (NPV) of the venture under constraints. The scheduling model is critically sensitive to the economic value volatility of block, block weight, and operational capacity. In order to deal with the OPPS uncertainties, various approaches can be recommended. Robust opti...
متن کاملA genetic algorithm approach for open-pit mine production scheduling
In an Open-Pit Production Scheduling (OPPS) problem, the goal is to determine the mining sequence of an orebody as a block model. In this article, linear programing formulation is used to aim this goal. OPPS problem is known as an NP-hard problem, so an exact mathematical model cannot be applied to solve in the real state. Genetic Algorithm (GA) is a well-known member of evolutionary algorithms...
متن کاملA new algorithm for the open-pit mine scheduling problem
For the purpose of production scheduling, open pit mines are discretized into threedimensional arrays known as block models. Production scheduling consists in deciding which blocks should be extracted, when they should be extracted and how each extracted block should be processed. Blocks which are on top should be extracted first, and capacity constraints limit the production each time period. ...
متن کاملA Multistage Stochastic Programming Approach to Open Pit Mine Production Scheduling with Uncertain Geology
The Open Pit Mine Production Scheduling Problem (OPMPSP) studied in recent years is usually based on a single geological estimate of material to be excavated and processed over a number of decades. However techniques have now been developed to generate multiple stochastic geological estimates that more accurately describe the uncertain geology. While some attempts have been made to use such mul...
متن کاملAn imperialist competitive algorithm for solving the production scheduling problem in open pit mine
Production scheduling (planning) of an open-pit mine is the procedure during which the rock blocks are assigned to different production periods in a way that the highest net present value of the project achieved subject to operational constraints. The paper introduces a new and computationally less expensive meta-heuristic technique known as imperialist competitive algorithm (ICA) for long-term...
