Análise do processo produtivo com foco nos desperdícios do Lean Manufacturing: um estudo de caso em uma empresa de artefatos de concreto

Abstract

Lean manufacturing aims to increase process efficiency and eliminate waste, allowing companies to restructure themselves to face market competition. In this sense, the objective of this work was to analyze the production process of a concrete artifacts company focusing on the seven wastes of lean manufacturing in order to propose improvement actions for the company. To develop this research, the case study structure developed by Miguel (2007) was used as a basis. Bibliographic searches and a review of the existing literature were carried out first to define a theoretical conceptual framework for the work, in order to result in a mapping of the literature on the subject. Visits to the company were carried out between June 1, 2024 and June 29, 2024. Data collection was based on a set of open interviews, direct observations, on-site verifications of the phenomenon studied, photographs, notes and videos. The interviews addressed issues related to the principles of lean production and were carried out with workers from the company's production unit at all hierarchical levels. The main problems identified were low productivity, lack of a preventive or predictive maintenance plan, lack of qualified labor and ergonomic conditions. Based on the analysis of the process, an initial action plan was drawn up to improve the process. As a starting point, it is suggested to implement a 5S program in the company.
