Abstract

With the evolution of business, increasing competition and with increasingly demanding consumers, organizations are forced to worry about the production of their products and services offered as well as the availability of them. Designing the demand to identify the necessary quantity of the products is fundamental for the organization, with it the company manages to better manage its stocks avoiding the lack of the products for the customer service. This work aims to propose a model of inventory management for the company Polo Industrial Electronics that helps in reducing the unavailability of the products in its stock. Inventory management studies seek to optimize inventory investments, since stocking stands for money standing still. The present research refers to an applied research with quantitative approach. Regarding the objectives the research is characterized as descriptive, and as to the procedures for research the research is classified as bibliographical, documentary and a case study. For the data collection, a report was used to move inventory of the products of the company under study, also information on orders of service performed and purchase orders issued by the company was used. In order to obtain the results, we first identified the product unavailability index in the stock, then the two demand forecasting methods were tested so that the necessary demand could be projected. For the two prediction models we calculated the prediction errors that served to identify the method that best suits the reality of the company, resulting in the choice of the additive method of decomposition of time series. Subsequently, it identified the inventory management systems presented in the literature, and based on the characteristics of the company, the continuous review method to be applied for inventory management was selected. In order to better manage the company's inventory, we performed the safety inventory, order point, economic purchase lot and maximum inventory calculations so that the company will make better use of its financial resources and customers will be served promptly. Finally, it was suggested that the company carry out the inventory of rotating inventory, thus avoiding divergences between the physical quantities and the quantities presented in the management system.
