Abstract: For capturing static and dynamic aspects of an application domain on a conceptual level THM-Nets being based on semantic data model and Petri net concepts have been proposed. In this paper THM-Nets are generalized to Timed THM-Nets thus providing modeling concepts for capturing physical and logical time aspects of a slice of reality. These modeling concepts are based on an appropriate notion of physical and logical time within the semantic data model THM.
Keywords: time model; timed THM-net; physical (and) logical >time aspects; temporal hierarchic data model.
