An assembly line operates 7.5 hours per day with a demand of 200 units per day. The activities and their task times that go into the production of a unit are as follows:

Activity	Precedent	Activity Times (minutes)
A		5
B	A	4
C	B	9
D	B	10
E	C	3
F	E	2
G	D	6
H	G	5
I	F, H	3

1. Draw the precedence diagram. What is the process task time? What is the total labor content for a unit of product?
2. What is the Cycle time (takt time) for the demand of 200 units per day? Interpret this number.
3. What is the theoretical minimum number of workstations?
4. Assign tasks to workstations using the longest operating time.
