SISTEMA DE GESTIÓN DE INVENTARIOS PARA COMPAÑÍAS DE HARDWARE - CASO DE ESTUDIO

Abstract

Some hardware assembly and marketing companies do not apply proper inventory management, causing failures in the product records, which can lead to shortages if there is an unexpected high demand, affecting the costs of ledgers and generating the need for an inventory management system. For this purpose, a methodological process was carried out, starting with the diagnosis, identifying the main factors that need to be improved concerning the management of merchandise, such as lack of inventory policies or reorder level, found through tools such as the SWOT, Ishikawa Diagram and Vester Matrix. Subsequently, an ABC classification was made, in which 1664 products are ordered and 118 of them belong to category A and applying goodness-of-fit tests. Then, the system is characterized and the mathematical models that adjust to the proposed conditions are selected: CEP without shortages and discount by suppliers, which is validated with a simulation. As a result of this process, the policy is established and a 95% improvement in the information quality is observed as a result. Variables part of the models are proposed and developed in the simulation and improve the system by 20% because they impact several products which are the most essential for the company.
