Controle pela carga de trabalho de um sistema flexível de manufatura

Abstract

O objetivo deste artigo foi calcular tempos de atravessamento e inventário médios em um sistema de manufatura flexível, que atende muitas ordens, de tamanho e mix variado. Foi aplicado o workload control (controle por carga de trabalho) para o cálculo da situação atual, e simulação computacional (software ProModel) para avaliar duas situação alternativas: aumento na demanda e redução na demanda. O método de pesquisa foi a modelagem quantitativa. Os resultados apontam que atualmente há excesso de inventário, provocado por desequilíbrio entre demanda e entrega da manufatura, o que é típico em sistemas de filas. Seria necessário sincronizar melhor entradas e saídas. Os cenários simulados apontam que a manufatura não suporta aumento de carga, crescendo continuamente o inventário, até a operação tornar-se inviável. Para estabilidade do inventário, seria necessário reduzir a demanda, se for mantido o atual regime de trabalho, com entradas aleatórias e independentes.
