Abstract(s)
A Marinha Portuguesa tem vindo a desenvolver vários processos de inovação
abertos e colaborativos, com vista a contornar os desafios que atualmente enfrenta. A
presente dissertação de mestrado constitui-se como um contributo para o âmbito da
inovação e da melhoria contínua, utilizando as metodologias Kaizen e Lean.
O objetivo do trabalho de investigação é a identificação das ferramentas de
melhoria contínua que melhor se adequam à gestão da manutenção dos helicópteros da
Marinha Portuguesa, identificando para isso o estado atual do processo e os desperdícios
do mesmo.
O estudo incidiu sobre quatro das oito oficinas do Serviço de Apoio do
Departamento de Manutenção da Esquadrilha de Helicópteros. O estado atual do processo
encontrava-se com elevados tempo de espera dos materiais necessários à manutenção de
segundo escalão dos equipamentos provenientes do Serviço de Aprontamento, o que
acarretava impacto financeiro para a organização. Com o foco na resolução deste
problema foram ainda encontrados outros desperdícios: o transporte, desperdício do
próprio processo, movimentações e stocks de equipamento inoperacional. O estudo
resultou num plano para reduzir ou eliminar esses desperdícios.
Foram estudadas várias ferramentas de melhoria contínua, sendo as que melhor se
adequam ao processo as seguintes: o ciclo PDCA, o Diagrama-de-Causa-Efeito, a Gestão
Visual, a ferramenta 5Whys, VSM, 5S, 5W2H, FMEA, SIPOC, 4K´s do Kaizen e o
Sistema Pull. Foram ainda recolhidas várias ideias de melhoria de cada encarregado de
oficina alvo de estudo, para um posterior estado intermédio entre o estado atual e o estado
ideal.
Com a presente dissertação de mestrado pretende-se alocar menos recursos ao
processo de gestão da manutenção dos helicópteros da Marinha Portuguesa, ao reduzir ou
eliminar as etapas que não criam valor, libertando esses mesmos recursos, nomeadamente
os recursos humanos, para que os mesmos possam surgir com novas ideias para melhorar
o processo.
The Portuguese Navy has been developing several open and collaborative innovation processes, with a view to overcoming the challenges it currently faces. This master's thesis is a contribution to the scope of innovation and continuous improvement, using Kaizen and Lean methodologies. The objective of the research work is to identify the tools for continuous improvement that are best suited to the maintenance management of Portuguese Navy helicopters, identifying the current status of the process and its waste. The study focused on four of the eight workshops of the Helicopter Flight Maintenance Department Support Service. The current state of the process was with high waiting times for the materials necessary for the maintenance of the second level of equipment from the Finishing Service, which had a financial impact on the organization. With the focus on solving this problem, other wastes were also found: transport, waste from the process itself, movements and inoperative equipment stocks. The study resulted in a plan to reduce or eliminate this waste. Several continuous improvement tools were studied, the following being the ones that best fit the process: the PDCA cycle, the Cause-Effect Diagram, the Visual Management, the 5Whys, VSM, 5S, 5W2H, FMEA, SIPOC, 4K's of Kaizen and the Pull System. Several ideas for improvement were also collected from each person in charge of the workshop being studied, for a subsequent intermediate state between the current state and the ideal state. With this master's thesis, it is intended to allocate less resources to the maintenance management process of the Portuguese Navy's helicopters, by reducing or eliminating the steps that do not create value, freeing these same resources, namely human resources, so that they can come up with new ideas to improve the process.
