Propostas de melhorias para o setor de planejamento e controle da produção através dos princípios lean: um estudo de caso em uma empresa de pré-fabricados

Abstract

The growth and economic importance of the construction industry in Brazil is indisputable. Despite its continuous progress over decades, low productivity still persists, highlighting the growing need for rationalization. Companies in this field are constantly looking for ways to achieve greater productivity, quality and efficiency in the management. In this context, the use of prefabricated elements has emerged as a viable alternative for a more efficient implementation of rationalization. However, the industry of prefabricated elements requires rigorous studies and the application of continuous and efficient methods to achieve productivity and quality. Therefore, efficient Manufacturing Planning and Control (MPC) is imperative. In this sense, the concept of Lean Construction, based on the principles and techniques of Lean Production, has become an essential management tool for increasing the productivity of the MPC sector, focusing on the best use of resources and, above all, eliminating waste. This study analyzes manufacturing planning over nine weeks, where it was used the Percentage of Completed Plans indicator from the Last Planner system to measure and monitor the efficiency of short-term planning, along with the waste associated with the manufacturing process. Finally, suggestions were made for Lean tools and practices to help improve the efficiency of the MPC sector and processes, avoiding the recurrence of the problems identified in this study.
