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</em></span> معادن روباز، توزیع کامیون، مدل های ریاضی، بهره وری تولید Open-pit mines, Truck Dispatching, Mathematical Models, Productivity 81 92 http://ijiepm.iust.ac.ir/browse.php?a_code=A-10-1-147&slc_lang=fa&sid=1 Ahmad Makui amakui@iust.ac.ir 180031947532846001041 180031947532846001041 Yes Ebrahim Teimoury 180031947532846001042 180031947532846001042 No Arbie Sarkissian 180031947532846001043 180031947532846001043 No
