Introduction to fuzzy logic

The concepts introduced by fuzzy mathematics are of interest to all engineers, wherever formal or probabilistic measurements are not possible.

Such cases can be found in many techniques:

• or because there is no antecedent history;

• or because it involves man-machine interactions;

• especially when we have to implement new scientific developments for which only a few experts are able to provide data; these data are not always numerical and are often obtained through knowledge expressed by semantics, whose level of truth we seek to qualify.
