Abstract(s)
Devido à globalização da economia, à constante procura pela melhoria da qualidade dos produtos juntamente com a redução dos custos e tempos de produção torna-se imperioso a implementação de metodologias que otimizem os processos de produção. Esta dissertação aborda uma das mais promissoras metodologias de otimização de processos, a engenharia concorrente, a qual tem vindo a ser utilizada por um número crescente de organizações no desenvolvimento do processo do produto. Trata-se de uma ferramenta que assenta no princípio de tarefas paralelas/simultâneas, com vista a uma redução do lead time do produto bem como a uma melhoria da qualidade do mesmo, confiando no agendamento paralelo das atividades ao longo do ciclo de vida do produto. Este método fomenta o trabalho em equipa dando grande destaque ao papel da comunicação entre os diferentes membros. Este estudo, aplicado numa indústria de cabos elétricos, mais concretamente ao ramo de alta tensão, que tem como base um processamento sequencial, tem como principal objetivo analisar o impacto da implementação duma estrutura organizacional de Engenharia Concorrente no tempo de desenvolvimento do produto, na sua qualidade e no seu lead time. Com a implementação de um Projeto Piloto de Engenharia Concorrente no setor dos cabos de alta tensão, foi obtida uma redução de 70,8% no tempo total de projeto. Consequentemente à redução do processo inicial de projeção do cabo e de respostas às consultas requeridas, estima-se uma redução do lead time do produto na ordem dos 20%. A qualidade dos produtos finais é também influenciada pela nova estrutura organizacional com uma melhoria estimada na ordem dos 50 aos 83%, o que revela uma diminuição de 15.813 no número das fichas de defeito, com resultante redução de 7.350.287,46€ nos custos, num horizonte temporal de cinco anos. Neste mesmo período é previsível uma redução de 9.097 operações, no que toca aos retrabalhos, o que representa em média uma diminuição de 3.769.873,78€.
Due to the globalization of the economy, the constant search for improving the quality of products together with the reduction of costs and production times, it is important to implement methodologies that optimize production processes. This study addresses one of the most promising process optimization methodologies, concurrent engineering, which has been used by an increasing number of organizations in the development of the product process. It is a tool based on the principle of parallel/simultaneous tasks, with a view to reducing the lead time of the product as well as improving its quality, relying on the parallel scheduling of activities throughout the product's life cycle. This method encourages teamwork, giving great emphasis to the role of communication between different members. This study, applied in an electrical cable industry, more specifically to the high voltage division, which is based on sequential processing, has as main objective to analyze the impact of the implementation of an organizational structure of Concurrent Engineering in the time of product development, in its quality and its lead time. With the implementation of a Project Pilot in Concurrent Engineering in the high voltage cable sector, a reduction of 70.8% in the total project time was obtained. As a consequence of the reduction in the initial cable projection process and in the response to the required queries, it is estimated that the product lead time will be reduced by 20%. The quality of the final products is also influenced by the new organizational structure with an improvement in the order of 50 to 83%, which reveals a decrease of 15,813 in the number of defect files, with a resulting reduction of 7,350,287.46 € in costs, in a five years period. In the same period, a reduction of 9,097 operations is expected, with regard to rework, which represents, on average, a decrease of 3,769,873.78 €.
