The purpose of this study is to describe a methodology to assess the financial viability of radio frequency identification (RFID) applications and the main contributions of this technology. The impact of RFID technology on supply chain processes was assessed using an Internal Rate of Return analysis. An extensive, six-month discussion and refinement process with the logistics and supply chain managers of the company under study was conducted to validate the procedure and to collect the necessary data. Such technology enables inventory control, tracking of parts/products and customer satisfaction. The viability of using RFID technology for inventory control and product tracking was confirmed. Among the benefits obtained: the reduction of one worker from the inventory team, reduction in the costs for replacing a component and reduction in the costs incurred with defective components were found. This is one of the few attempts to quantify RFDI technology’s contribution.Keywords: Economic Engineering. RFID. Radio Frequency Identification. Financial Viability Analysis. Internal Rate Of Return.

Este artigo tem como objetivo fazer uma proposta de aplicação da tecnologia RFID-Radio Frequency Identification (Identificação por Radiofreqüência), em empresas montadoras de microcomputadores, para o controle de estoque e rastreabilidade de insumos/produtos. Para justificar a vantagem da aplicação da tecnologia RFID, utilizou-se a Análise dos Modos de Falha e seus Efeitos (FMEA-Failure Modes and Effect Analysis) com foco específico em FMEA de Processo. A proposta de integração da tecnologia RFID foi apoiada na análise FMEA de Processo de uma montadora de microcomputadores, para identificar e avaliar as falhas potenciais, e propor ações de melhorias utilizando a tecnologia RFID, considerando a realidade das empresas do Pólo de Informática de Ilhéus/BA. Neste estudo, foi possível comprovar a viabilidade da tecnologia RFID para o controle de estoque e rastreabilidade do produto. Tal comprovação foi obtida pelos seguintes aprimoramentos do processo produtivo: (a) redução de um posto de trabalho na expedição; (b) redução dos custos de substituição por componente com equivalência superior; e (c) redução do tempo de leitura do pallet de produto acabado. Outras melhorias foram adicionalmente aportadas à empresa com a utilização da tecnologia RFID. Palavras-chave: RFID; FMEA de processo; site survey; automação de processo; operação. 1. Introdução Segundo Martins (1998), a frequente competição entre empresas força empresários a garantir que as demandas dos consumidores sejam satisfeitas da melhor forma possível, a um custo
This paper presents a methodology for the integration of RFID technology into microcomputer assembly companies. Such a technology enables inventory control, tracking of parts/products and customer satisfaction. The methodology was developed to identify and evaluate the production process in an assembly company and to apply the process FMEA to evaluate potential faults and propose improvement actions for the use of RFID technology. The methodology was validated in a company from the Pólo de Informática de Ilhéus/BA. In this study, the viability of RFID technology for inventory control and traceability of the product was confirmed. Among the benefits obtained were the reduction of one of the workers from the inventory team, reduction in the costs of substituting a component, and reduction in lead-time.
