An assembly line is to be designed to operate 8.5 hours per day and supply a steady demand of 275 units per day. Here are the tasks and their performance times:

TASK	PRECEDING TASKS	PERFORMANCE TIME (SECONDS)
A		60
B		28
C		20
D	A	50
E	B	55
F	C	58
G	D	30
H	E	60
I	F	10
J	G	25
K	H, I	67
L	J, K	30

What is the workstation cycle time required to meet the desired output rate?

In seconds per unite?

What is the theoretical minimum number of workstations required to meet the desired output rate?

Note: Round up your answer to the next whole number.

Assign tasks to workstations using the longest task time.

Note: Leave no cells blank - be certain to enter "0" wherever required.

What is the efficiency of your line balance, assuming it is running at the cycle time determined in part b?

Note: Round your answer to 1 decimal place.

Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 8.5 hours per day using regular time.
