O presente trabalho foi desenvolvido durante um período de estágio, em contexto industrial, na empresa Continental Mabor – Indústria de Pneus, S.A., incorporado na Direção de Engenharia Industrial e surge pela necessidade de se efetuar um estudo aos processos de Recuperação de pneus (vulcanizados) e de melhorar o processo de avaliação das limpezas industriais. O estudo aos processos de Recuperação de pneus teve como principal objetivo a determinação e atualização dos tempos-padrão dos respetivos processos, os quais foram obtidos através da análise de métodos e estudo dos tempos. A atualização dos tempos-padrão permitirá quantificar com maior precisão a capacidade e eficiência dos processos, assim como as necessidades de mão-de-obra e de equipamentos, atividades pelas quais a Direção de Engenharia Industrial é responsável. Foram determinados os tempos-padrão dos quatro tipos de processos de Recuperação de Pneus existentes na empresa, com um nível de confiança de 95% e um erro de 10%. O estudo desenvolvido envolveu a condução de uma metodologia para a obtenção desses tempos, a qual permitiu ter em consideração e pesar todas as variantes existentes dentro de cada processo. A melhoria do processo de avaliação das limpezas industriais teve como objetivo uma redução significativa do tempo despendido pelos técnicos que a efetuam. Para o efeito foi desenvolvida uma solução em linguagem Visual Basic for Aplications (VBA) e que foi incorporada nas atuais ferramentas (MS Excel®) que servem de suporte a este processo. A solução implementada permitiu alcançar o ganho de tempo atribuído à execução deste processo de 25,9% e um ganho de tempo diário total na carga de trabalho destes trabalhadores de 12,27%.
The present work was developed during an internship period, in an industrial context, carried out in the company Continental Mabor – Indústria de Pneus, S.A., incorporated in the Board Unit of Industrial Engineering and arises from the need to carry out a study on the processes of tire recovery (vulcanized) and to improve the evaluation of industrial cleaning process. Tire recovery processes study had as main objective the determination and updating of the standard times of the respective processes, which were obtained through the analysis of methods and time study. The updating of the standard times will allow to quantify with greater precision the capacity and efficiency of the processes as well as the needs of manpower and equipment, activities for which the Directorate of Industrial Engineering is responsible. The standard times of the four types of Tire Recovery processes in the company were determined, with a confidence level of 95% and a 10% error. The study involved the conduction of a methodology to obtain these times which allowed to take into consideration and to weigh all the variants existing within each process. The improvement of the evaluation of industrial cleaning process had as goal a significant reduction of the time spent by the technicians who carry it out. For this purpose, a Visual Basic for Applications (VBA) language solution was developed and incorporated into the current MS Excel® tools that support this process. The implemented solution allowed to achieve the gain of time attributed to the execution of this process of 25.9% and a total daily time gain in the workload of these workers of 12.27%.
