How layout design differ for service organisation as compared to manufacturing organisation. Dr. Lori Baker, operations manager at Nesa Electronics, prides herself on excellence assembly- line balancing. She has been told that the firm needs to complete 96 instruments per 24- hour days. The assembly- line activities are:

Task	Time (min)	Predecessors
A	3	-
B	6	-
C	7	A
D	5	A,B
E	2	B
F	4	C
G	5	F
H	7	D,E
I	1	H
J	6	E
K	4	G,I,J
	50

1. Draw the precedence diagram
2. If the daily (24 hour) production rate is 96 units, what is the highest allowable cycle time?
3. If the cycle time after allowances is given as 10 minutes, what is the daily (24 hour) production rate?
4. With a 10- minute cycle time, what is the theoretical minimum number of stations with which the line can be balanced?
5. With a 10- minute cycle time and six workstations, what is the efficiency?
6. What is the total idle time per cycle with a 10-minute cycle time and six workstations?

What is the best work station assignment you can make without exceeding a 10- minute cycle time and what is the efficiency?
