est: Problems Help Save & ExitSut Lazer Technologies Inc. (LTI) has produced a total of 20 high-power laser systems that could be used to destroy any approaching enemy missiles or aircraft. The 20 units have been produced, funded in part as private research within the research and development arm of LTI, but the bulk of the funding ceme from a contract with the U.S. Department of Defense (DoD) Testing of the laser units has shown that they are effective defense weepons, and through redesign to add portability and easier field maintenance, the units could be truck-mounted DoD has asked LTI to submit a bid for 100 units. The 20 units that LTI has built so far cost the following amounts and are listed in the order in which they were produced: Use Exhibit 6.4 and Exhibit 6.5 COST UNIT NUMBER MILLIONS) CoST UNIT NUMBER ( MILLIONS) $14.0 10.9 $6.3 6.2Explanation / Answer
a. 80 ± 1
You can estimate the learning percentage by averaging the learning between the 1st and 2nd units, the 2nd and 4th units, the 4th and 8th units, and the 8th and 16th units.
In this case that would be: (10.9/14.0 + 8.7/10.9 + 7.1/8.7 + 5.7/7.1)/4 = 80%.
b. 371,980,000 ± 1000
You can figure this out by using the cumulative factors in Exhibit 6.5. You want to find the time needed for the 21st through 120th units. That is equal to the time for all 120 units minus the time for the first 20. So take the cumulative factor for 120 units, subtract off the cumulative factor for 20 units, and multiply the result by the first unit’s production time.
c . 2,997,400 ± 1000
You can figure this out by using the unit factors in Exhibit 6.4. You would simply take the unit factor for the 120th unit and multiply by the time for the first unit.
You can estimate the learning percentage by averaging the learning between the 1st and 2nd units, the 2nd and 4th units, the 4th and 8th units, and the 8th and 16th units.
In this case that would be: (10.9/14.0 + 8.7/10.9 + 7.1/8.7 + 5.7/7.1)/4 = 80%.
