Development of a goal programming model for optimization of truck allocation in open pit mines
Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) model presented by Michalakopoulos and Panagiotou is developed to determine an optimal truc...
متن کاملSwarm –Based Truck-Shovel Dispatching System in Open Pit Mine Operations
The dispatch of trucks and shovel has always been an important component in the success of open pit mine operations. Dispatch systems have evolved from manual to today automatic with almost no human intervention. Although dispatching systems available today are “pseudo real time” and efficient, the optimal dispatching is realized over subsets of the fleet when dealing with large fleets. This ap...
متن کاملAn Approach to Locate an in Pit Crusher in Open Pit Mines
Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....
متن کاملA Chance Constrained Integer Programming Model for Open Pit Long-Term Production Planning
The mine production planning defines a sequence of block extraction to obtain the highest NPV under a number of constraints. Mathematical programming has become a widespread approach to optimize production planning, for open pit mines since the 1960s. However, the previous and existing models are found to be limited in their ability to explicitly incorporate the ore grade uncertainty into the p...
متن کاملA Mixed Integer Programming Formulation for the Heterogeneous Fixed Fleet Open Vehicle Routing Problem
The heterogeneous fixed fleet open vehicle routing problem (HFFOVRP) is one of the most significant extension problems of the open vehicle routing problem (OVRP). The HFFOVRP is the problem of designing collection routes to a number of predefined nodes by a fixed fleet number of vehicles with various capacities and related costs. In this problem, the vehicle doesn’t return to the depot after se...
