In this paper, the mauvais fonctionnement and l'effet des erreurs se propagent par causalite d'une variable a l'autre, en satisfaisant finalement les contraintes du procede en regime permanent.Abstract:
Dans une analyse qualitative le mauvais fonctionnement et l'effet des erreurs se propagent par causalite d'une variable a l'autre, en satisfaisant finalement les contraintes du procede en regime permanent. Les contraintes des series d'equations algebriques, sont representees par des equations de confluence stationnaires. La causalite est representee par le graphe oriente signe etendu (Extended Signed Directed Graph: ESDG)read more
