Analizar y comparar la gestión de inventarios de materia prima clásica, versus el modelo (s, Q), con demanda y nivel de servicio definido, para la industria metalmecánica. Caso: “Metalmecánicos del Ecuador”.

Abstract

This research work had the goal of analyzing and comparing two inventory management models applied at “Metalmecánicos del Ecuador”, a metal-mechanic company where the current model will be contrasted with a new proposal. The data will be collected at the organization with the goal of identifying opportunities for financial improvement and reducing inventory management costs, since opportunities to boost the company´s profitability have been identified. The metal-mechanic sector in Ecuador has been affected by constant variations in Steel prices, its main raw material, since Price fluctuations depend on the international stock market and thus do not allow Ecuadorian companies to have continuous and controlled resupply due to the uncertainty generated by variable prices. This study used the assessed company, which is part of one of the country´s most important strategic sectors, to test a controlled resupply model in which the demand is known and the level of service required by the company is defined prior to inventory management. After assessing both models, we will conduct an analysis of the costs generated by each one of them, comparing them and verifying which option generates the best results in this economic sector.
