Diskussion:Linear optimization: Mathematical formulations of problems presented in the course 5

Introduction:

The introduction is a little bit short. It would be better to have more informations about why it is necessary to formulate a mathematical model and what is needed to do that.

Mathematical Formulation:

It would be better if you would write an explanation for the variables of the restriction directly under the formula and not after the non-negativity conditions. Also your restrictions only allow "smaller than" conditions, while it could be possible for some restrictions to be "bigger than" conditions : "aij*xj => bi".

Approach:

The structured way how you wrote down the approach of formulating a mathematical model is good, but the order of task 2 and 3 should be switched, since the restricions belong to the objective function and not the other way around.

Example 1:

The NNC are false.
