Aplicação de uma Metodologia de Lógica Fuzzy à Gestão de Estoques: Um Estudo de Caso em uma Instituição Pública

Abstract

This paper presents a proposal for implementing a fuzzy logic approach to inventory management of a public institution of the federal administration, located in Manaus-AM. Initially, a review of the literature on logistics and supply management is conducted. They are then discussed issues relating to inventory management. After that, we discuss issues related to the fuzzy logic. The proposed methodology will allow a better control over inventory, since it will replace traditional quantitative methods of inventory management. The data were collected directly from the warehouse of the institution under study, and refer to the movement of stock of a particular item during the year 2009. The use of fuzzy logic has attracted increasingly more attention from researchers in different areas of knowledge, being, however, that the great challenge posed to them is the modeling of the data collected, due to its computational support needed application. The interaction with the observed values, operated by the rules of fuzzy logic allows a better control of stock in a warehouse, such as service, parts and tender, since it deals with uncertainty and subjectivity. The methodology appears to be able to indicate a better performance of the quoted shares, being able to operate on an automated tracking and inventory management.
