A company is designing a product layout for a new product. It plans to use this production line eight hours a day in order to meet the projected demand of 480 units per day. The tasks necessary to produce this product:

Task	u	v	w	x	y	z
Predecessor	-	u	u	w	x	v,y
Time (seconds)	30	30	6	12	54	30

What is the expected minimum output for this new product if the production line will use the 8-hour day shift?
