A Fuzzy Logic Approach Towards Truck Dispatching Problem in Surface Mines
This paper presents a mixed integer linear programming model to solve truck dispatching problem in surface mines. Although, all thus far developed models in the literature approach to the truck dispatching as a deterministic problem, we believe that most of the input parameters for truck dispatching are uncertain. To account for the parameters’ inherent uncertainties, we implemented a fuzzy approach to solve the developed mathematical model. The developed model is implemented on a surface mining case study and results are compared against a benchmark model implementation on the same case. The results show that the model developed in this paper requires smaller fleet of trucks to meet the production requirement of the mine in comparison to the benchmark model.
