Center node: "Measuring Complexity of Business Process Models Integrated with Rules"
  Abstract: Complexity assessment is often used in software and knowledge engineering for controlling the quality and improving models. In fact, complexity is one of the main factors affecting the understability and maintainability of models. Although there are many complexity measures that can be used in order to assess the complexity of process models or rule bases, the complexity of the integrated model of processes with rules is not addressed and constitutes a challenging issue. In this paper, we consider a new metric that is suitable for measuring the integrated models and present a short evaluation based on the selected cases of different size.
