This means that we cannot expect sophisticated supports for checking consistency among analysis models and validating/verifying their appropriateness. As quality of analysis models determines that of succeeding design and implementation phases, formalization of the analysis phase is very important. In this paper, we propose a formal approach to analysis phase, consisting of (1)formal analysis models, (2)uni cation of the models, (3)an axiom system for consistency veri cation and (4)veri cation environment.enText/Conference Paper1617-5468
