Análisis del impacto de la incertidumbre en la gestión de inventarios en una empresa que opera en el sector petrolero y propuesta de un sistema de control de ítems agrupados

Abstract

This research project analyzes the incidence of uncertainty in inventory management in a company that operates in the oil sector. In the first instance, the suppliers and products of greatest relevance to the company are established, using the Analytic hierarchy process (AHP), in which three criteria for suppliers and four criteria for products were considered, defining two categories, one for purchasing products. national and another for international purchase products. With the established suppliers and products, the historical demand data is consolidated, with which the coefficient of variation was calculated, and the type of demand managed by the company was established. Other relevant data in the study are delivery time, ordering costs, service levels and unit value. The data acquired allows the calculation of exchange curves, in which the current situation of the company was analyzed and what would be the optimal scenario by comparing the relevant total cost at each point of the curve. The final part of this work allows proposing an inventory control system considering the effect of uncertainty and based on the relevant total cost.
