An approach to animate Object-Z specifications using C++

An approach to animating Z specifications

Generating Object-z Specifications

The importance of use cases has been growing for the last few years. We believe they are important to help developers capturing requirements. The work presented here formalises use cases using basic temporal logic to define history invariants within Object-Z class schemas. This is accomplished by proposing a set of formal frameworks integrated within a process.

Refactoring Object-Z specifications

This paper describes an approach to transferring techniques of refactorings to formal methods. We use syntactical rewriting rules to express refactorings on Object-Z specifications. In contrast to programming languages here refactorings can be formally proven to preserve the behaviour of the specification. We give an outline of such a proof of behaviour preservation.

Reasoning about Object-Z Specifications

This paper presents a method of reasoning about Object-Z speciications. The approach utilises the modularity inherent in Object-Z speciications to simplify proofs. Properties proved for a class in isolation can be used when that class is either inherited by another class or instantiated as part of a system of interacting objects. Proofs using structural induction and the notion of object integr...

Refinement of Object-Z Specifications Using Morgan-s Refinement Calculus

Morgan’s refinement calculus (MRC) is one of the well-known methods allowing the formality presented in the program specification to be continued all the way to code. On the other hand, Object-Z (OZ) is an extension of Z adding support for classes and objects. There are a number of methods for obtaining code from OZ specifications that can be categorized into refinement and animation methods. A...
