5. (12 points) A production that was halted for six months is ready to recommence operations. a (4 points) Given the following information calculate the percentage of learning lost in each of the five categories. b. (4 points) Given the following information determine the lost learning factor. Use your learning lost calculations from part a above. c. (4 points) Assume that after the break they use the retrograde method to determine their costs. Prior to the break they produced 400 units and were using an 90% learning curve that is still valid. The first unit cost was 300 man hours. The first lot produced after the break will contain only 100 units and the estimated learning lost due to the break is 100 man hours. Find F and L, the retrograded first and last units for this new lot. 5.
