Bell Computer is planning to launch a new high-end server. Nine steps or tasks are required to assemble this computer. Daily demand is expected to be 84 units and there are three 8-hour shifts available each day to meet this production quota.

Task	Req'd Time (in minutes)	Predecessor
A	15	None
B	11	A
C	5	B
D	4	B
E	13	A
F	3	C, D
G	9	F
H	13	E
I	5	G, H

 

What is the total time (in minutes) to produce one server?

 

What is the total time (in minutes) for this production line? (Round your answer to one decimal place.)

What is the theoretical minimum number of workstations required for this production line? (Round up your answer to the nearest whole number.)

 

After assigning task A to workstation 1, which task (or tasks) should you assign to workstation 2?

 

		B
		C
		D
		E
		B or E
		C and D

Suppose you assign task B to workstation 2, which task (or tasks) should you then assign to workstation 3?

		E
		E (by itself), or C, D and F
		E and H
		C and D
		C, D and F

Assume you assign tasks C, D, and F to workstation 3, and task E to workstation 4, which task (or tasks) should you assign to workstation 5?

		H
		G and H
		H and I
		G and I

Given your task assignments to workstations, what is the actual number of workstations required?

What is the cycle time (in minutes) for this production line?

What is the combined idle time (in minutes) for this production line?

What is the overall efficiency for this production line? (Write your answer as a percentage, and display your answer to two decimal places.)
