Hi Sir
The first batch of a new product took six hours to make and the total time for the first 16 units was 42.8 hours, at which point the learning effect came to an end.
Calculate the rate of learning
I got the equation 42.8 = 6*16*$4
Sir how to use the calculator if \i want to work with log as its easier for me.6
the equation for the answer is 42.8 = 16 x (6 x r4), why as it should start with 6?
How do you estimate the learning rate and learning effect
I don’t understand where you got your first equation from!
The average time per unit for 16 units is 42.8 / 16 = 2.675
The average time for 1 unit is 6 hours.
If the learning rate is r, then the average time for 2 units is 6 x r
Average time for 4 units is 6 x r^2
Average time for 8 units is 6 x r^3
Average time for 16 units is 6 x r^4
so 6 x r^4 = 2.675
r^4 = 2.675 / 6 = 0.44583
so r = 0.817
Goodness thanks Sir. you make F5 almost easier than F6. Again THANKS
r^4 = 2.675 / 6 = 0.44583
so r = 0.817
which button on the calculator to use
i used Ln 0.44583/ Ln 4 but its not working
