On Best Corrected Mixture Problems in Metallurgy: A Case Study

الملخص EN

We consider three simple mixture problems occurring in metallurgy.

The first problem considered is the classic minimum cost mixture problem.

For the second problem, we consider finding a correction to a given mixture, a premix, without considering the cost of this premix.

We only consider the cost and the weight of the quantity used as a correction.

We show that the minimum cost correction does not correspond to the minimum weight correction, and we built the Pareto curve that gives all intermediate solutions between these two extreme solutions.

Finally, the third problem is the correction problem for a nonfree premix.

The correction is done to obtain a minimum cost corrected mixture.
