| Research Abstract |
In this study, we considered a limited-cycle problem in multi-period with a balancing approach. A limited-cycle problem in multi-period is systematically classified to non-reset model and reset model. In non-reset model, first we considered controlling the production process by switching to a faster processing rate at a given period (period-based) or a station (station-based). Next, the mathematic formulations of the total expectation for the above were proposed. Finally, the property of an optimal switching period and an optimal switching station were investigated in detail through numerical experiments. Meanwhile, in reset model, first the mathematic formulation of the total expectation was proposed. Then the problem of workers' assignment to each station was considered. When two kinds of worker exist, properties of workers' optimal assignment which can take a minimized total expected cost of the production process were proposed under a relation between distribution of workers' processing time and costs. Finally, some properties of which three kinds of worker exist were given by numerical experiments.
