Abstract(s)
Cada vez mais, existe uma maior competitividade entre organizações, surgindo novos concorrentes diariamente a um nível nunca visto. Para que as organizações consigam sobreviver face a estas condições, necessitam de agir continuamente na redução de custos e em simultâneo aumentar o seu nível de eficiência e eficácia, no entanto nem sempre esta tarefa é fácil de se realizar. O conhecimento da filosofia Lean e a sua aplicação nas empresas, tem-se revelado uma grande ajuda nesta tarefa, uma vez que permite às organizações, reduzirem o seu nível de desperdício, conseguindo desta forma reduzir custos aumentando em simultâneo a sua eficiência. No entanto, antes da aplicação de qualquer ferramenta Lean, é necessário perceber em que patamar as empresas se encontram, ou seja, deve-se primeiro medir, para que depois se possa atuar. O presente documento, apresenta a construção de um modelo que tem como objetivo, medir o nível Lean de uma organização, permitindo, segmentar a mesma em várias partes, conseguindo perceber em simultâneo quais os departamentos dentro da organização com níveis Lean inferiores ao desejado. A ferramenta apresentada, tem por base a utilização do modelo fuzzy logic, ou lógica difusa, uma vez que o Lean é um tema muito subjetivo. Para a construção do modelo utilizou-se a ferramenta Matlab e o seu módulo “fuzzy”. O caso de estudo foi realizado na empresa Vision-box, podendo se ter concluído que a mesma atingiu um nível lean.
Increasingly, there is greater competition between organizations, with new competitors appearing daily at a level never seen before. In order for organizations to survive in the face of these conditions, they need to act continuously to reduce costs and at the same time increase their level of efficiency and effectiveness, however this task is not always easy to accomplish. The knowledge of Lean philosophy and its application in companies, has proved to be a great help in this task, since it allows organizations to reduce their level of waste, thus managing to reduce costs while simultaneously increasing their efficiency. However, before applying any Lean tool, it is necessary to understand what level the companies are at, that is, one must first measure, so that one can then act. This document presents the construction of a model that aims to measure the Lean level of an organization, allowing it to be segmented into several parts, being able to simultaneously perceive which departments within the organization have Lean levels below the desired. The presented tool is based on the use of the fuzzy logic model, since Lean is a very subjective theme. To build the model, Matlab tool was used, and its “fuzzy” module. The case study was carried out in the company Vision-box, and it can be concluded that it reached a lean level.
