Abstract(s)
A melhoria do processo produtivo é um objetivo continuo das organizações. O Lean Seis
Sigma (LSS) pertence ao último leque de metodologias de melhoria contínua e surge da
simbiose entre o pensamento Lean e a abordagem Seis Sigma (SS), com o intuito de
colmatar as fraquezas de ambas as estratégias. O LSS foca-se na eliminação do desperdício
e redução da variabilidade do processo, através da aplicação da ferramenta de cinco etapas
Define, Measure, Analyse, Improve, Control (DMAIC) com o intuito de resolver problemas
que afetam o processo produtivo das organizações.
O objetivo desta dissertação é a melhoria do processo produtivo através da implementação
do LSS a um caso de estudo, a Haco Etiquetas S.A. Para tal, ocorre uma caracterização e
desenvolvimento de um ciclo DMAIC com o intuito de dar reposta à problemática
levantada.
Inicialmente é definido o problema da organização que queremos ver resolvido. No caso
em estudo, a problemática incide na produção de etiquetas com defeitos, resultando em
desperdício. De seguida ocorre uma mensuração do mesmo. A fase seguinte consiste numa
análise causa-efeito ao principal motivo de defeitos, estipulado na fase de análise.
Posteriormente, são apresentadas propostas de melhoria, uma relacionada com a
mudança da estratégia de manutenção e a outra sobre a implementação de um sistema
Andon aos teares. Por último, a fase de controlo surge como o términus deste ciclo.
O LSS é uma abordagem de melhoria de processos, abrangente e contínua, pois fornece
ferramentas tais como o ciclo DMAIC, que capacitam a organização a resolver problemas
identificados de uma forma estruturada, cimentando as etapas até se alcançar o objetivo
da sua implementação.
Improving the production process is an ongoing objective for organizations. Lean Six Sigma (LSS) belongs to the latest range of continuous improvement methodologies and arises from the symbiosis between Lean Thinking and the Six Sigma (SS) approach, to address the weaknesses of both strategies. The LSS focuses on eliminating waste and reducing process variability, through the application of the five-step tool Define, Measure, Analyze, Improve, Control (DMAIC) to solve problems that affect the productive process of organizations. The objective of this dissertation is to improve the production process through the implementation of the LSS to a case study, Haco Etiquetas S.A. To this end, there is a characterization and development of a DMAIC cycle to respond to the problem raised. Initially the problem of the organization that we want to be solved is defined. In the case under study, the problem focuses on the production of defective labels, resulting in waste. Then there is a measurement of it. The next phase consists of a cause-effect analysis of the main reason for defects, stipulated in the analysis phase. Subsequently, proposals for improvement are presented, one related to the change in the maintenance strategy and the other on the implementation of an Andon system to the looms. Finally, the control phase appears as the end of this cycle. The LSS is a process improvement approach, comprehensive and continuous, as it provides tools such as the DMAIC cycle, which enable the organization to solve identified problems in a structured way, cementing the steps until the objective of its implementation is achieved.
