2 A. The product is sold at $4.00 per unit. Assume that the cost of a drilling machine (fixed cost) is $30,000 and the company produces 8,000 units per week. Assume that four drilling machines are used for production. If the company had an option to buy the same part at $3.00 per unit, what would be the break-even number of units? (In your calculations, use the two-digit cost per unit from page d-1. Round your answer to the nearest whole number.)

The following diagram represents a process where two components are made at stations A1 and A2 (one component is made at A1 and the other at A2). These components are then assembled at station B and moved through the rest of the process, where some additional work is completed at stations C, D, and E.

Assume that one and only one person is allowed at each station. Assume that the times given for each station represent the amount of work that needs to be done at that station by that person, with no processing time variation. Assume that inventory is not allowed to build in the system.

B. What is the average hourly output of the process when it is in normal operation?

3. A An assembly line is to operate eight hours per day with a desired output of 240 units per day. The following table contains information on this products task times and precedence relationships:

TASK	TASK TIME (SECONDS)	IMMEDIATE PREDECESSOR
A	60
B	80	A
C	20	A
D	50	A
E	90	B, C
F	30	C, D
G	30	E, F
H	60	G

B. What is the workstation cycle time?

C. . Balance this line using the longest task time. (Leave no cells blank - be certain to enter "0" wherever required.)

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

A1 0.3min. B C D E A2 0.75min.0.65min.0.60min.0.55min. 0.4min
