In this thesis entitled “APPLICATION OF MATHEMATICAL MODELS TO IMPROVE UNITARY LOADING AND CARRYING OPERATIONS IN AN OPEN PIT MINE IN SOUTHERN PERU.“ Two mathematical models are presented, the first linear programming with a special case that is the Hungarian method, which consists of an arrangement of rows and columns that seeks to minimize the objective function, explained to the optimal designation of operators of auxiliary equipment in a mine. open pit, this with the objective of improving production, reducing costs, improving operational safety, among others; On the other hand, the following mathematical model is the dynamic programming model applied to the estimation of the truck fleet for excavators based on costs; where the fleet that needs to be assigned to a shovel will be determined based on the costs applied in dynamic programming; these mathematical models are part of operations research which has an infinity of mathematical models applicable to mining, the applied software is the tora, to solve the systems of equations. As a conclusion, it was reached that an optimal designation of the equipment, would mean that the operators do not have so many errors reported during the month, which will result in the care of the components of the equipment and therefore the operating costs will be reduced; On the other hand, when calculating the number of trucks that a shovel should have based on cost, we notice that there is a turning point in which we must make the decision to increase more equipment and generate queues or take the optimal number of trucks, in this second part. The analysis was also seen from the time it takes to carry out a cycle taking into consideration 4 haul routes, choosing the route in which the time is minimum in order to increase the number of trips and with it the production. In the annexes, the resolution of the system of equations with the Tora software of the 40-variable equation system is presented, as well as the summary of the feasible result, as well as the simulation in the Talpac software of the number of trucks.
