Object-oriented real-time database design based on Petri nets

Abstract

This paper introduces extensions in an Object ColouredPetri Net model named G-CPN to model a real-time control and database system. These extensions allow the designer to apply an unified approach to model the control objects and the database objects of a real-time system. Syntactic and semantical constraints are considered for realtime database objects. The semantical constraints can be mapped to Petri net constructions. An example based on a manufacturing cell is shown.

Object-oriented Real-time Database Design based on Description Logics

“…The G-CPN (Perkusich et al, 1995) model allows the modeling of syntactical and semantical features related to the objects in a real-time database. The semantical features can be mapped to Petri net constructions.…”

“…Elementary descriptions of description language are atomic concepts and atomic roles (Baader et al, 2003). In defining the concept name by DL, it (Lee et al, 1994) × × × × × G-CPN (Perkusich et al, 1995) × × × × × × RODAIN (Taina and Raatikainen, 1997) × × × × BeeHive (Stankovic and Son, 1998) ×…”

“…Thereby, the real-time database community has migrated towards object-oriented technology. Several research projects have proposed object-oriented data models for real-time databases (Prichard et al, 1994), (Lee et al, 1994), (Perkusich et al, 1995), (Taina and Raatikainen, 1997), (Stankovic and Son, 1998), (Idoudi et al, 2010), and (Louati et al, 2011).…”

RTO-RTDB: A Real-Time Object-Oriented Database Model

“…In [13], Perkusich et al describe the G-CPN model which is based on object-oriented concepts and colored Petri nets. The G-CPN notations incorporates the notions of module and system structures in Petri nets.…”
