In the current research the control variables and their interacting into the loading and hauling fleet are analyzed, which are monitored and controlled in the dispatch system included the time of the productive process of each equipment and their activities. The equipment activities are into the timeline, each equipment has 24 hour per day the 365 or 366 days per year (in leap year) and it is mainly distributed by 3 parts, first it is the time available by operation, second it is the time for equipment maintenance and the last is the time used for overhauling or assemble the equipment The timeline is considered fixed in a stipulated period (as sample one day has 24 hours or 86,400 seconds) in term of the activities of the production cycle, considering that they are independent processes, the control variables contribute inversely to the final value of production, which It means that if the equipment achieve their cycles in less time the production rises. The problem consists of the impact generated by individual practices of the shift crew and the plans changes without previous analysis and to determine which variables are the most relevant and to set this analysis it is necessary modeled the fleet cycle based on the principle of fleet capacity balance usually called “fleet match“ where those capacities are equivalent. The surplus production capacity is reduced adding delays time up to set within the minor production capacity to balance each other, as example, if the loader fleet capacity is higher, it is necessary to add as truck waiting time, in contrast, if the hauling fleet capacity is higher, it is necessary to add as queue time at the loader fleet. The production process model was developed and simulated with Montecarlo’s method to determine the impact for each control variable and the result obtained as sensitivity analysis, each variable it is powered by the impact expressed in tonnages and their weighted geometric mean of those highest impact factor it is represents the key performance indicator (KPI) proposed. Finally, the model was tuned for each sceneries proposed and compared against each real production, which is demonstrated that those practices proposed are the best option for production process.
