Major studies on cell production have put the emphasis on technical factors (machine order/layout, family part grouping, workflow sequence, etc.), it is still insufficient to investigate how workers' aptitude affect the productivity of production cells. In this paper, we make an experimental study on the impact of workers' aptitude in cell production(More)
In this paper, we deal with the vehicle routing problem where vehicles have finite capacities and demands of customers are uncertain. We represent the uncertain demands by triangular fuzzy numbers and interpret them as possibility distributions. According to the same consideration as the stochastic programming with recourse, we treat the influence of the(More)
This paper analyze the relationship between the cycle time and the configuration factors of a rotary rack system consisting of a rotary rack and a conveyor, by using the cycle time as our criteria for evaluation. Using the queue theory of an M/G/1 model, which has a simpler theoretical formula than that of a GI/G/1 model, to compare the cycle time between(More)
