Abstract
In this paper, we propose a reactive Kanban system for the unstable changes of product demand. In the proposed system, the exponentially weighted moving average chart is utilized for detecting the unstable changes of product demand, and the appropriate number of Kanbans is calculated on the basis of the detected changes. By adjusting the number of Kanbans dynamically to the changes, the proposed system is able to respond to the changes. The performance of the proposed system is analyzed by simulation experiments, and it shows the effectiveness of the proposed system.
