Solodovnikov A. Information technology of the synthesis of information system software architecture based on graph model

The thesis is devoted to solving scientific and practical task - developing model, methods and informational technology of structural synthesis of information system software architecture in terms of changing end-user requirements. The work improved multilevel graph model of information system software architecture that is used to adapt the software architecture to the changeable requirements of the end-user. Based on the multilevel graph model of information system software architecture, author proposed methods for reducing the structural and functional complexity of information system software architecture, including the method of union nodes of graph model and method for assessing the functional complexity of software architecture. Also author proposed method of automatic verification of constraints to software that is formed. Based on the developed methods, author proposed information technology and instrumental software for structural synthesis of information system software architecture.
