The line operates 24 hours each day without breaks. a) Calculate the needed number of Kanban cards if each station will be controlled by Kanban. Use 10% safety factor. b) If the entire line is to be controlled by Conwip system what should be the number of cards needed. For this, use 10% safety factor, and assume the card travel time from machine 6 to machine 1 is 12 minutes. c) Which machine is the bottleneck machine on this line? Why? 2.
