Production Scheduling with uncertain supply a new solution to the open pit mining problem
Optimization and Engineering, 2013Co-Authors: Salih Ramazan, Roussos DimitrakopoulosAbstract:The annual Production Scheduling of open pit mines determines an optimal sequence for annually extracting the mineralized material from the ground. The objective of the optimization process is usually to maximize the total Net Present Value (NPV) of the operation. Production Scheduling is typically a Mixed Integer Programming (MIP) type problem containing uncertainty in the geologic input data and economic parameters involved. Major uncertainty affecting optimization is uncertainty in the mineralized materials (resource) available in the ground which constitutes an uncertain supply for mine Production Scheduling.

The influence of deposit uncertainty on mine Production Scheduling
International Journal of Surface Mining Reclamation and Environment, 1999Co-Authors: Martin L. Smith, Roussos DimitrakopoulosAbstract:A variety of algorithms are available for short-term mine Production Scheduling. All assume that the key characteristics of the deposit model are smooth and that a unique representation of the orebody exists. Is the current approach to Production Scheduling valid if these assumptions are violated? Both a stochastic orebody model based on conditional simulation and an estimated model based on kriging are used as input to a math programming-based scheduler. Deviations in resulting schedules are presented in terms of the impact of geologic uncertainty on Production, the efficacy of the traditional approach and suggestions for integrating stochastic models into the Production Scheduling framework.

Framework of Open-pit Mine Production Scheduling System Based on Multi-Agent Technology
Journal of University of South China, 2020Co-Authors: Wu Chang-zhenAbstract:Considering the characteristics of complex nonlinear and processes over a broad area of the open-pit mine Production Scheduling system,the multi-agent technology with distributed management features is introduced to establish the Production Scheduling system of open-pit mine,which is based on multi-agent technology.The Production Scheduling system is composed of tasks agent,Production Scheduling agent,blasting agent,transportation agent,crushing agent and resource agent.The ANFIS with the stronger nonlinear curve fitting capability is used to model the local and global system.The model is optimized by particle swarm optimization algorithm,and then the optimal Production Scheduling program is obtained.The program provides certain reference value for the enactment of the actual mine Production Scheduling program.

A hierarchical open-pit mine Production Scheduling optimisation model
International Journal of Mining and Mineral Engineering, 2020Co-Authors: Hesameddin Eivazy, H. Askari-nasabAbstract:A hierarchical open-pit mine Production Scheduling methodology linking the optimal strategic open pit mine plan to the optimal medium-term Production schedule is presented. The main objective of this paper is to develop, implement, and verify a mathematical programming framework for the optimal medium-term open-pit mine Production Scheduling using Mixed Integer Linear Programming (MILP). The objective of the medium-term mine Production schedule is to minimise operating costs, including waste rehabilitation, processing, mining, haulage, and rehandling costs. To verify the proposed hierarchical model, an iron ore case study is presented. The results are interpreted and analysed to verify the applicability of the model in terms of mining practice. The main contributions of the medium-term Production Scheduling optimisation model are: multiple destinations modelling including stockpiles, processing plants, and waste dumps; decision making on selection of routes/ramps to minimise the haulage costs; and modelling stockpiles using MILP.

Robust stochastic mine Production Scheduling
Engineering Optimization, 2010Co-Authors: Mustafa KumralAbstract:The Production Scheduling of open pit mines aims to determine the extraction sequence of blocks such that the net present value (NPV) of a mining project is maximized under capacity and access constraints. This sequencing has significant effect on the profitability of the mining venture. However, given that the values of coefficients in the optimization procedure are obtained in a medium of sparse data and unknown future events, implementations based on deterministic models may lead to destructive consequences to the company. In this article, a robust stochastic optimization (RSO) approach is used to deal with mine Production Scheduling in a manner such that the solution is insensitive to changes in input data. The approach seeks a trade off between optimality and feasibility. The model is demonstrated on a case study. The findings showed that the approach can be used in mine Production Scheduling problems efficiently.
