Aspect-Oriented Formal Specification for Real Time Cyber Physical Systems

This paper proposes an approach for specifying real time cyber physical systems based on aspect-oriented formal specification, which exploits the diversity and power of existing formal specification languages. There is no requirement that different aspects of a system should be expressed in the same language. So the different aspects can be specified by one formal specification technique or different formal specification techniques. In this paper we provide some ideas for aspect oriented formal specification of real time cyber physical systems. real time cyber physical systems can be divided into different aspects, each aspect can be specified independently. After each aspect has been accomplished, it can be woven back to the system. This aspect oriented formal specification method simplifies the requirement analysis process of Real Time Cyber Physical Systems. A case study illustrates the specification process of aspect-oriented formal specification for real time cyber physical systems.
