ICCPN: Interval-based Conditional Colored Petri Net

Nowadays, rules make part of any software system including real-time applications and games, meanwhile an event can trigger many different rules according to the conditions controlling these rules. Although rules are core part to many kinds of systems, its maintenance and update are not easy without affecting the whole application. Hence, many systems have presented rules as a separate layer from the application; such as: SAMOS, Sentinel, Snoop, SnoopIB and CCPN. CCPN is a model that was used in an Amplified CDBB-500 architecture; which is a system supporting active database within its architecture. In this paper, we propose some extensions on CCPN to be able to present rules as a separate layer from the application, to support time-based events, and to add other important features which were agreed and implemented in other systems such as: Snoop and SnoopIB.
