QoS modeling of cyber physical systems by the integration of AADL and aspect-oriented methods lichen zhang

Abstract

This paper proposes an aspect-oriented QoS modeling method based on AADL. Aspect-Oriented development method can decrease the complexity of models by separating its different concerns. In model-based development of cyber physical systems this separation of concerns is more important given the QoS concerns addressed by Cyber physical Systems. These concerns can include timeliness, fault-tolerance, and security Architecture Analysis and Design Language (AADL) is a standard architecture description language to design and evaluate software architectures for embedded systems already in use by a number of organizations around the world. In this paper, we present our current effort to extend AADL to include new features for separation of concerns., we make a in-depth study of AADL extension for QoS. Finally, we illustrate QoS aspect-oriented modeling via an example of transportation cyber physical system. © Springer Science+Business Media Dordrecht 2014.
