Framework for Modeling C~4ISR Requirements

There has been no mature model for expressing needs and expectations of people within the area of national defense,and it is considered as the most important business in C4ISR requirement analysis.In order to cope with this problem,an approach has been put forward in the paper.Firstly,basic concepts were analyzed,the concept of C4ISR requirement system was put forward based on concept analysis,and the idea of modeling C4ISR requirements was presented.Secondly,elements of C4ISR requirements model were studied. Metaclasses in the domain of C4ISR requirements and relationships among the metaclasses were distilled and defined.Therefore,C4ISR requirements models were designed on purpose to solve C4ISR requirement problems.Lastly,the paper provides the process of modeling C4ISR requirements based on element analysis. What C4ISR requirement models require and how to build the models are clarified.The approach elaborates what the real C4ISR requirements are and it can serve as the guideline of modeling C4ISR requirements.
