Approach to Reducing Production Lead Time to 1/20 in Small-scale Corrugated Cardboard Factory

In response to population decline in Japan, the production demand has shifted from mass production to quick production of multiple products in small lot since 2005. In this paper, we delineate the method that conducts production in one-twentieth (1/20) of usual lead time (hereinafter referred to as L/T), which is revolutionary short, is able to respond to the needs of the users concerning delivery, among QCD (quality, cost and delivery). This proposed method is energy efficient, and it is designed for the companies that strive to be the top company in the region. It aims for development of corrugated cardboard makers and optimum efficiency of management.
