An assembly line is to be designed to operate 13 hours per day and supply a steady demand of 325 units per day. Here are the tasks and their performance times:

TASK	PRECEDING TASKS	PERFORMANCE TIME (SECONDS)	TASK	PRECEDING TASKS	PERFORMANCE TIME (SECONDS)
a		48	g	d	43
b		58	h	e	38
c		73	i	f	23
d	a	63	j	g	33
e	b	88	k	h, i	53
f	c	23	l	j, k	67

b. What is the workstation cycle time?

c. What is the theoretical minimum number of workstations? (Round up your answer to the next whole number.)

d. Assign tasks to workstations using the longest operating time. (Leave no cells blank - be certain to enter "0" wherever required.)

e. What is the efficiency of your line balance? (Round your answer to 1 decimal place.)

f. Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 13 hours per day in regular time. (Round your answers to the nearest whole number.)
