Object Oriented Petri Nets in Business Process Modeling

Abstract

Business systems have to adapt to changing requirements coming from their environment. The rate is continuously increasing and leads to massive use of computer based systems. To specify the systems in a way that allows for adaptability and exibility adequate techniques are necessary. The disadvantages using traditional modeling techniques are partially overcome by Business Process Petri nets (BPP-nets) which are informally introduced in this contribution. The key concepts are an object oriented structure of the net models, allowing to partition the model according to an application and also to follow a process centered approach. Workflows within the system can be modeled in separate objects and thus allow the dynamic adaptation of the system if the environment requires a behavioral change.
