Abstract(s)
Devido ao crescimento populacional e ao aumento da competitividade nos mercados, a nível global, os japoneses da Toyota desenvolveram e aperfeiçoaram o Toyota Production System, entre 1940 e 1970, que lhes permitiu uma articulação adequada com tais mercados, de forma a sobreviver ao constante dinamismo e às exigências que os caracterizam, principalmente durante uma das crises mais marcantes na história da indústria - a crise do petróleo. Esta forma de trabalho inovadora, mais tarde denominada por Lean, permitiu a esta empresa evitar ao máximo a ocorrência de falhas durante os processos, e de garantir que todos estes agreguem valor ao produto ou serviço final.
A filosofia Lean foca-se na redução dos desperdícios, sem comprometer a qualidade dos produtos e a satisfação do cliente. Esta filosofia, que é suportada por diversos métodos e ferramentas, é apresentada numa vasta gama de trabalhos científicos, tanto de cariz puramente académico, como incluindo estudos de caso realizados em ambiente industrial. Assim, este trabalho de investigação tem como principal objetivo, apresentar uma análise quantitaiva sobre os estudos que têm sido realizados nas última duas décadas, sobre o Lean. Pretendem-se analisar os tipo e fontes de informação que a comunidade científica tem reunida sobre o pensamento Lean, em termos de artigos científicos existentes em sites, que fornecem acesso baseado em assinaturas a várias bases de dados, como é o caso da Web of Science. Posto isto, de modo a organizar a informação sobre a temática do pensamento Lean e com o objetivo de apurar como, quando, e por quem este é abordado em ambiente académico e industrial, foram considerados 194 artigos referentes a estudos de caso, onde é evidente a sua aplicabilidade prática.
Como resultado do estudo em causa, concluiu-se que de uma forma geral os métodos e ferramentas, quando empregues aos diversos tipos de indústria, levam à obtenção de ganhos significativos para as organizações que os implementam, o que comprovou que o Lean é uma filosofia universal, devido à sua versatilidade e aos benefícios que dela advêm.
Due to the population growth and the increase in the competitiveness in the markets at a global level, the Japanese of Toyota developed and perfected the Toyota Production System, between 1940 and 1970, which allowed them an adequate articulation with such markets, in order to survive the constant dynamism and the demands that characterize them, especially during one of the most striking crises in the history of the industry - the oil crisis. This innovative way of working, later called Lean, allowed this company to avoid as much as possible the occurrence of failures during the processes, and to ensure that all these add value to the final product or service. The Lean philosophy focuses on reducing waste, without compromising product quality and customer satisfaction. This philosophy, which is supported by several methods and tools, is presented in a wide range of scientific works, both of a purely academic nature and including case studies carried out on industrial environment. Thus, the main objective of this research work is to present a quantitative analysis on the studies on Lean, which have been carried out in the last two decades. The aim is to analyze the types and sources of information that the scientific community has gathered about Lean thinking, in terms of scientific articles existing on websites, which provide subscription-based access to various databases, such as the Web of Science. That said, in order to organize the information on the theme of Lean thinking and with the objective of ascertaining how, when, and by whom it is approached in an academic and industrial environment, 194 articles referring to case studies were considered, where it is evident its practical applicability. As a result of the study in question, it was concluded that, in general, methods and tools, when used in different types of industry, lead to significant gains for the organizations that implement them, which proved that Lean is a philosophy universal, due to its versatility and the benefits that come from it.
