Process Step Problems

Using the Simple Process Step Calculator solve the following problems:

Problem 1

Considering the default process:

a) Plot the outgoing cost and yield as a function of the incoming cost and yield.   

b) Why doesn't the incoming cost have any effect on the outgoing yield?  Similarly, why doesn't the incoming yield have any effect on the outgoing cost?

c) What type of step would have to be added to this process for the incoming yield to effect the outgoing cost?

Problem 2

Considering the default process:

a) What effect does the lifetime quantity of parts have on the outgoing cost and yield from the process?   

b) What property or properties of the process steps could be set to zero to make the results independent of the lifetime quantity of parts?

Problem 3

Does step order make any difference?  In other words, if you interchange step 1 and step 2 do you get the same result?  Why or why not?
