A verification method of software acceptability

Software requirements validation is one of the hot problems of software engineering field, for the formal verification of software acceptability, this paper presents a formal verification software acceptability method. This method uses the 4-variable model to character the software system requirements and the software behavior, and gives a formal description of the 4-variable model based on the generic model of Tabular expression, and converts the Tabular expression into predicate logic knowledge base to verify the software acceptability. The analysis shows that the proposed method is effective, and the software acceptability can be verified.
