Methodological aspects of an approach for verification of object-oriented programs

Generalized nets (GN) are created as a tool for modeling and controlling real processes. The mathematical tools which GNs have make them an effective and convenient instrument for software modeling. Models of software systems can be created by means of GN; specifications of properties, connections between software modules, relations between classes and member functions of classes can be defined; properties of software systems can be proven. The paper describes an application of the GN for building models of programs, for defining specifications, describing properties and relationships between program units, for verification of object-oriented programs (OOP). An approach for verification of OOP is presented from methodological point of view. The approach is intended for research and educational purposes.
