It takes 60 hours to make the first unit of a product and a 95% learning curve applies. How long will it take to make the second and third units?
【参考答案及解析】
Average time for first 2 units = 60 × 95% = 57 hours Total time for first two units = 57 × 2 = 114 hours Time for 2nd unit = 114 – 60 = 54 hours. Total time for first 3 units = 3 × 55.315 hours = 165.945 hours Time to make 3rd unit = (165.945 – 114) = 51.945 hours = 52 hours approximately.
