Resumo
A complexidade do planejamento e da programação de linhas de montagem de multimodelos de produtos, aliada ao seu comportamento dinâmico e à natureza estocástica dos tempos de montagem, sugere uma abordagem baseada na simulação para uma programação mais efetiva. Este trabalho utilizou a simulação para analisar a necessidade e alocação de mão-de-obra, considerando diferentes cenários, em função do número de montadores, do arranjo dos montadores na linha, da forma de trabalho dos montadores, da utilização das relações de paralelismo entre as atividades e da forma de entrada dos motores na linha. O estudo foi realizado em três linhas de sub-montagem de motores, de uma empresa do setor automobilístico, caracterizadas pela demanda diária variável, com data definida de entrega do produto acabado.

Abstract
The complexity of planning and scheduling of multi-model assembly lines, joined to the dynamic behavior of these lines and the stochastic nature of the assembly times make a simulation based approach more effective to support the line scheduling. This work uses the simulation to analyze the manpower need and allocation, in different scenarios considering the number of operators, the operator's distribution on the workstations, the use of concurrency relationship of activities and the arrival sequence of engines in the line. This study was accomplished in three engines subassembly lines in a company of the automotive sector, characterized by a variable daily demand with defined delivery date for the finished products.
