Hello,
I am enjoying your book, thank you very much. However there is at typo after the third table, it reads : "The next step is to formulate an objective function describing that describes how..." --> Here one of the describe is redundant.
Moreover there is a mix-up in the constraints, it should be :
y_u + y_v <= x_a labor A
2*y_u + y_v <= x_b labor B
Indeed it requires 2 hours of labor B for version U, not 2 hours of A. Either change this in the table (easy) or in the model (which would require changing the code as well).
