Proposta de metodologia para implementação de ferramentas do Lean Manufacturing para redução do Lead Time produtivo em uma empresa do ramo eólico: um estudo de caso

Abstract

One of the main challenges of organizations today is to adapt quickly to the constant changes in the organizational scenario and the growing demand of society for products of good quality and compatible price. In order to remain competitive, companies must build intelligent and flexible teams capable of developing alternatives to improve their processes and minimize their waste, and consequently their costs. Lean manufacturing appears as a great alternative in this context, since it eliminate any unnecessary process keeping only the activities that add value. Thus, the general objective of this study is to propose, to gather and to implement a set of tools based on Lean Manufacturing in a company of the wind energy sector to enable the identification and elimination of waste, implementation of improvements and reduction of the lead time of production process. For the implementation of the proposed model, the steps of the Kaizen method, defined by Liker (2005), and the principles of the PDCA, defined by Imai (2014). Through the application of this method in one of the sectors of the company, it was possible to identify and implement improvements that allowed the elimination of activities that did not add value, the reduction of the productive lead time of the sector by 14%, the increase in productive capacity and significant gains in the 5S of the areas.
