PROPOSTA DE UM MÉTODO DE AVALIAÇÃO PARA SELEÇÃO DE PROJETOS DE MELHORIA DO FLUXO PRODUTIVO USANDO A ÁRVORE DE PERDA E TEORIA DAS RESTRIÇÕES

Abstract

The aim of this paper is to propose a software evaluation for selection of projects to improve the production flow, which allows simulations creating scenarios involving product demand and efficiency of equipment, through the index of OEE (overall equipment effectieness). The theoretical basis of the proposed evaluation method was constructed from the Theory of Constraints (TOC - Theory of Constraints) and analysis of the reduction potential of the conversion cost (cost take out) that provide projects to be selected, based on the tree losses valued. In this context the selection of projects to improve the production flow that provides positive impact on the prospects of meeting the demand, utilization of manufacturing resources and reducing the cost of conversion includes the expected result from the use of the proposed evaluation method, demonstrated in this Article from an application example.
