Abstract

L'invention concerne un outil et un procédé permettant la simulation d'une installation technique avec au moins une instance de simulateur (1, 10) qui comprend plusieurs éléments (2...8, 15, 16, 18) réalisés chacun au moins sous forme d'une application. Plusieurs éléments (3...8, 15, 18) exécutent un calcul, cyclique et basé sur un modèle, de leurs nouvelles valeurs de sortie en fonction des valeurs d'entrée respectives. Pour éviter une commande centralisée du déroulement, le déroulement est commandé orienté par le flux de données par le fait qu'à chaque entrée d'un élément est attribuée une cellule de mémoire par le biais de laquelle il est affiché si une nouvelle valeur d'entrée est déjà traitée ou non. Des valeurs d'entrée nouvellement calculées sont transmises, selon le flux de données en arrière-plan, aux entrées des éléments seulement lorsque ces valeurs se trouvent dans l'état « traité ». D'une manière avantageuse, une mise en parallèle et, en particulier, une exécution efficiente des calculs sont rendues possibles du fait que des éléments peuvent être répartis entre des calculateurs locaux et/ou des calculateurs dans un réseau.
