4) Assembly line of factory Z consists of 6 tasks (A, B, C, D, E, F) and they require 4, 8, 8, 12, 16 and 20 minutes for assembly, respectively. Total daily production time is 10 hours in factory Z and Workstation-Task allocation in its assembly line is as follows: Workstation 1: A

Workstation 2: B, C, D Workstation 3: E Workstation 4: F

a) Determine the bottleneck of the system. Calculate the minimum cycle time of this

system.

b) What is the output capacity of the factory?

c) Assume now that daily down time percent is 40% and the factory operates with

70% performance. What is the output capacity of the factory?

d) Explain how you can increase the output capacity of the factory by redesigning the

system. Can you increase the corresponding capacity by 100%?
