摘要：A software system is built by a number of concerns where a concern is composed by one or several functional requirements or non-functional requirements or both. In the software system development one of the essential principles is separation of concerns. Generally in the software system, separation of concerns is the process of breaking into many modules with meager overlapping each other. On account of that there may be few specific concerns which are not to be located into a single module which are said to be crosscutting concerns. Aspect-oriented programming (AOP) provides techniques for managing cross-cutting concerns into a single manageable module called, Aspect. AOP is used to solve many problems such as tangling and scattering representations. But the identification and specification of crosscutting concerns and considering it as aspects is not a trouble-free job. This proposed method uses colored Petri Nets for defining the concerns and its requirements and also for executing the final modeled software system which monitors transitions based on that it will determine the join-points in a desired moment ¨CBefore, After, Around and Replace operators by the action of Aspect module. Fan in analysis techniques is used for finding the dominant aspect in the system
