Abstract: The system values the abnormal situations of work and makes a decision choosing among three possible alternatives: Shot of the relé · Alarm. · Blocking the relé The method used to create this system consists on the formulation of rules of the Diffuse Logic. The antecedent of these rules contains the comparison operation among the mensuration of each flaw indicator and the relé shot conditions expressed by means of diffuse groups with adjusted membership according to the experience of the experts. The final conversion to the conventional logic is carried out by means of the NOT operation of threshold.

Resumen: El sistema valora las situaciones anormales de trabajo y toma una decisión escogiendo entre tres alternativas posibles:disparo del reléalarma. loqueo del relé El método utilizado para crear este sistema consiste en la formulación de reglas de implicación de la Lógica Difusa. El antecedente de dichas reglas contiene la operación de comparación entre la medición de cada indicador de falla y las condiciones de disparo del relé expresadas mediante conjuntos difusos con membresía ajustada según la experiencia de expertos. La conversión final a la lógica convencional se realiza mediante la operación NOT de umbral.
