| |Q, search Help Save & E 3 a pilot run of 10 units of a major product and found the processing time for each unit was as follows Use 4A5 and Exhibit 4A 6. 5 points 840 820 760 740 725 710 iate calculations, Round your a. According to the pilot run, what would you estimate the learning rate to be? (Do not round i answer to the nearest whole percent.) b. Based on (a whole number.) ). how much time would it take for the next 190 units, assuming no loss of learning? (Round your answer to the nearest Prey 3of3 Next De Type here to search DOLL

Solution

(a)

* 840 / 970 = 0.86597938; ** 760 / 840 = 0.9047619

So, the approximate learning rate is 90%

(b)

For 90% learning curve, from the exhibit 6.5

Improvement factor for 200 units = 105.0
Improvement factor for 10 units = 7.994

So, time required for the next 190 parts = 970 x (105 - 7.994) = 94,096 hours

(c)

From exhibit 6.4, for learning rate of 90%,

TIme required to produce 1000^th part = 970 x 0.3499 = 339 hours
