Checking the consistency of Object-Z formal specification based on theorem proof

A software formal specification is useful if and only if it is consistent or non-conflictive. However, checking the correctness or consistency of a formal specification is a difficult task. This paper proposes a method to prove its consistency or correctness by generating relevant theorem proofs. Checking the correctness and consistency of Object-Z formal specification is the main goal, which can make the specifier to get confident. Because Object-Z has inheritance property, this paper discusses it from different aspects, and focuses on the reuse of theorem proof. Finally, theorem prover Z/EVES is used to analyze and verify the Object-Z theorem proofs (semi-)automatically.
