a.                  What is the assigned cycle time (in minutes)?

b.                  What is the maximum output rate of this line in mixers per hour?

c.                  What is the total idle time per cycle?

d.                  What is the assembly line\'s efficiency?

Solution

a. Cycle time is 4 minutes which is governed by stations 3 and 4.

b. Maximum output is 60/4 =15 units per hour.

c. idle time per cycle = 1.0+0.5+0.0+1+1.5+0 = 4 minutes

d. efficiency is 20.0/24.0 = 83.3%
