本文提出了一个反应式准时制（JIT）订货系统的多阶段生产系统的不稳定变化的需求，不仅在均值，而且在方差。针对准时化订购系统，即看板系统，提出了缓冲区大小的反应式控制器。在所提出的系统中，不稳定的变化的平均值和方差的需求可以检测指数加权移动平均图的平均值和方差，并在每个库存点的缓冲区大小控制作为一个反应，检测到的不稳定的变化。通过仿真实验分析了该系统的性能。
This paper proposes a reactive just-in-time (JIT) ordering system for multi-stage production systems with unstable changes in demand, not only in the mean but also in the variance. For a JIT ordering system, that is, the Kanban system, a reactive controller of buffer size is proposed. In the proposed system, unstable changes in the mean and variance of demand can be detected by exponentially weighted moving average charts for mean and variance, and the buffer size at each inventory point is controlled as a reaction to the detected unstable change. The performance of the proposed system is analyzed by simulation experiments.
