Research On Aspect-oriented Requirement Analysis Method Of C~4 Isr System

C4ISR System Requirements Engineering is an important part of the building of military information technology, requirements analysis is an important part of the building of Requirements Engineering. It is the basis for building a C4ISR system which has a direct impact on the design and development work of the follow-up. This thesis mostly researches on the method of requirement analysis and framework.First the paper introduces the background of C4ISR system requirements analysis, proposes C4ISR system requirements development problems, and summarizes the status of domestic and foreign Requirements Engineering, requirement analysis methods research, as well as the status of aspect-oriented requirements analysis method. Put forward the application of aspect-oriented requirements analysis method based on the traditional requirements analysis methods which lays a sound foundation for later elaboration.The paper brings the aspect-oriented technology into the field of C4ISR system requirements for the development, in a second innovation in the field. The paper re-elaborates the concept of aspect-oriented technology, combining the characteristics of C4ISR system requirements development that provides a core theoretical basis for the latter approach.The paper puts framework based on capability as the basis for analysis. It builds the CMCA framework which includes Concept layer, Mission layer, Capability layer, and Activity layer, and then it anlyses the characteristics of CMCA framework, and concludes that aspect-oriented technology is suitable for analysis CMCA framework.In the aspect-oriented requirements analysis process, the paper adopts improved methods of Theme. Find aspect requirements among the requirement elements and aspect requirements will be packaged into a module for maintenance, reuse and understand. Through aspect-oriented requirements analysis specification of requirements become more structure-clear and modularity further improved.Finally, the paper verifies the rationality of the method through the case of air defense operational command information system.
