Aplicación de modelos matemáticos para la optimización de costos logísticos dentro de la cadena de suministro en el sector de comercialización del gas licuado de petróleo en la provincia del Azuay, año 2016

Abstract

This research studies the commercialization of Liquefied Petroleum Gas in the province of Azuay. It takes reference to information obtained from the year 2016. It has been accessed to 135 distribution warehouses and 1 collection center. They allow to determine that logistic costs are not adequately managed. Then, a structure and composition of logistics costs is proposed. It helps to determine that the costs that are the most relevant in this sector are: transportation, inventory and order processing costs. A general cost optimization model is proposed. This model is solved through Solver. Also, it has been obtained an optimum order quantity with restrictions. The research as well presents a comparison between current costs and optimized costs. Thereby demonstrating the benefit and contribution of the optimization of logistics costs in the studied sector. Some factors of inefficiency have also been identified. These factors influence the increase of logistics costs. Finally, are recommended some improvement actions
