Formal methods have been widely used in computer science and being improved day by day. Towards finite relation models, this paper advances a new formal method used by sextuple based on symbolic logic. It can use simple formal normative language to depict the relation between the modules in model exactly. With logical reasoning, it can analyse the models with theorem proving and model checking. In...
