Problem 4-1

AlwaysRain Irrigation, Inc., would like to determine capacity requirements for the next four years. Currently two production lines are in place for making bronze and plastic sprinklers. Three types of sprinklers are available in both bronze and plastic: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. Management has forecast demand for the next four years as follows:

	YEARLY DEMAND
	1 (IN 000s)	2 (IN 000s)	3 (IN 000s)	4 (IN 000s)
Plastic 90	33		42		54		51
Plastic 180	14		15		18		17
Plastic 360	51		54		61		68
Bronze 90	6		6		5		14
Bronze 180	4		4		6		12
Bronze 360	10		12		14		17

Both production lines can produce all the different types of nozzles. The bronze machines needed for the bronze sprinklers require four operators and can produce up to 15,000 sprinklers. The plastic injection molding machine needed for the plastic sprinklers requires five operators and can produce up to 240,000 sprinklers. Three bronze machines and only one injection molding machine are available.

What are the capacity requirements for the next four years? (Assume that there is no learning.) (Enter the demand values in thousands. Round your answers to 2 decimal places.)
