Haulage in open-pit mines allocates half of operational costs. Improvement in this system has significant effects in decrease of costs and increase of efficiency. Productivity in mines is a mixture of machinery efficiency and implementation of production strategies. In this paper after classifying dispatching models in open-pit mines, a new mathematical model will be introduced, to execute at the beginning and also during the working shift. Execution of the model before shift start creates a general vision of production parameters and grade control according to production strategies. Also execution of model during the shift with real-time information tries to keep the results near the standard deviation of initial results. This model can be used to develop heuristic models and truck dispatching simulation softwares
