You make steering wheels for Tesla using Kanban cards to authorize movement of incoming parts. In one portion of the system, a work center uses an average of 80 parts per hour while running. The manager has assigned an inefficiency factor of 0.14 to the center. Standard containers are designed to hold 5 dozen parts each. The cycle time for parts containers is 100 minutes. How many containers are needed?
Expert Answer
Demand = D = 80
T = 100/60 = 1.67
C = 12*5 = 60
X = 0.14
We will use the formula, N = DT (1+X)/C
=80*1.67*(1+0.14)/60 = `2.53 or 3
