Lean Manufacturing e Tecnologias da Indústria 4.0 em Pequenas e Médias Empresas para Eficiência Operacional

Abstract

Lean Manufacturing combined with Industry 4.0 (I4.0) technologies proposes a new perspective for industrial advancement. However, several aspects still require investigation, especially in the context of small and medium-sized enterprises (SMEs). The objective of this research is to present guidelines that support the implementation of Lean 4.0 in SMEs in the pursuit of operational efficiency. This work conducted a systematic literature review and collected empirical evidence through field research, focused on the integration between Lean Manufacturing and I4.0 technologies as a means of achieving greater operational efficiency in SMEs. The results obtained from the systematic literature review were analyzed from articles in the Web of Science and Scopus databases. The PRISMA methodology was adopted to select publications based on predefined criteria. The R® software was used to analyze the growth of publications by country, application areas, journals, among others, and the Vosviewer® software was used to map the main keywords and their connections. The results allowed for the identification of the tools most frequently associated with Industry 4.0 technologies in SMEs and the resulting benefits of this integration. Field research allowed for the evaluation of the results of digitizing Lean Manufacturing, Just-in-Time, Kanban, and 5S tools in Software as a Service (SaaS). Reductions in waste due to overproduction, unnecessary deliveries, decreased setup time, and a more organized work environment were observed. Furthermore, it was possible to assess the main guidelines in the Lean 4.0 implementation process in the company studied.
