Abstract

La présente invention concerne des systèmes et des procédés de suivi, dans le temps, de données enregistrées dans des systèmes. Les techniques décrites ici comprennent la possibilité de détecter et de classer des activités des systèmes et de produire des indicateurs de fonctionnement normal des systèmes et de détection d'anomalies. Les systèmes et procédés selon la présente invention peuvent représenter des activités se déroulant dans le système contrôlé d'une manière telle que les caractéristiques temporelles des activités puissent être enregistrées et servir à la détection, au classement et/ou à la détection d'anomalies, ce qui peut être particulièrement utile quand on a affaire à des systèmes et/ou des activités complexes.
