Implementación de un modelo de administración del inventario para una empresa importadora de vidrios y materiales para el sector automotriz e industrial

Abstract

This thesis arises of the need to improve the current service level delivered to the customer and costs associated with inventory management in a commercial company, using for this purpose the operations management, once identified that the company has not a management formal and structured system that allows efficient inventory control. To meet the objective of implementing an inventory management system, first it was classified the articles through the methodology ABC and focus our study on the items type A, after it was studied demand and product behavior, then it is conducted time series analysis and the forecasting method was selected. The periodic review system was defined for the implementation of inventory management model, because it is better suited to a probabilistic demand and the restrictions of the company. Monte Carlo simulation was used to predict the behavior of the real system implemented, with a review time of two months and a service level of 85%. Using metrics and performance indicators is evident that the fill-rate was improved by 4.95% and the annual cost of inventory were reduced by 23.93 %, these model results were obtained by simulation, where compliance is demonstrated of the project objectives.
