Resumo

Os intercãmbiadores de calor de placas soldadas são equipamentos fundamentais para os processos de esterilização na indústria farmacêutica, por isso é crucial desenhar planos de manutenção eficazes para evitar falhas que possam comprometer a confiabilidade desses processos. O objetivo desta pesquisa foi determinar, através da simulação de Monte Carlo, uma política ótima de manutenção para estes intercãmbiadores. Utilizou-se metodologia descritiva, aplicada e transversal baseada em desenho de campo. Foram estudados sete intercãmbiadores de calor em uma planta farmacêutica, servindo tanto como população quanto como amostra. Os instrumentos de coleta de dados incluíram a revisão dos registros existentes e validação pelos especialistas. O estudo demonstrou que a distribuição Weibull é uma ferramenta útil para modelar os tempos de falha dos intercãmbiadores de calor em uma planta e revelou que o tempo ideal de substituição é de aproximadamente 1,7 anos, com um custo mínimo associado de US$ 2.139. Estas constatações são essenciais para um planejamento eficaz da manutenção e substituição de equipamentos, bem como para a otimização de recursos económicos. Contudo, reconhece-se a necessidade de uma amostra maior e de mais dados para reforçar estas conclusões.
