Desenvolvimento de ferramenta para avaliação de projeto de produto com fim de vida sustentável baseada em modelo stage-gate aperfeiçoado com abordagem set-based

Abstract

There are several methods to manage a Product Development Process, all with the same purpose: to organize the activities and information flow. Among these methods, Stage-Gate appears to be one of the most adopted. In the other hand, the challenge to develop sustainable products grows bigger as resources grow smaller and Lifecycle Assessment arises to evaluate all phases of a product, from manufacture to disposal. Many products nevertheless are designed without consider its posterior reuse. This research has aimed at a way to evaluate environmental impact of a product’s end-of-life during a PDP, using a Stage-gate model improved with the insertion of Toyota’s Set-based approach and more than sixty end-of-life strategies, distributed over development stages. The result was the preliminary prototype of a tool, to be used by product designers. A case study was carried out to test the effectiveness of the proposed tool where, in the end of the development process, a Lifecycle Assessment is performed to an actual seat and the resulting seat alternatives. It was possible to verify improvements in the environmental performance mainly in product’s end-of-life destination, which was the target of this research. Also, improvements are highlighted concerning SimaPRO’s interface and the tool itself.
