All Rights Reserved. 27 Or you could do both: get rid of some of the balls and increase the output rate The black ball exits in two/fifths of a second.

The black ball now exits in seven seconds. Adding priority red balls slows down the black ball. OneSecond Actuator Understanding Dynamic Cycle Time PROPRIETARY 169。 1988 Thomas Group, Inc.

Dynamic Cycle Time Example Beginning board inventory 4600 Ending board inventory 3600 Boards out to stock 31500 = .13 (30 days/month) = days Average Work in Process Process Speed = (Beg. Inv. + End. Inv.) / 2 OUTS dCT = = = (4600 + 3600) 2 4100 31500 Month 31500 PROPRIETARY 169。 1988 Thomas Group, Inc.
