Ievlanov M. Models, methods and information technology of complex information systems architecture design based on functional requirements

Purpose of study - to solving actual scientific and applied problems of methodological bases, models, methods and information technologies to form a rational option description information system architecture created with the greatest possible satisfaction of functional requirements for suppliers and consumers and minimal costs to sell. The object of study - the process makroproektuvannya information systems, which includes requirements definition process owners, requirements analysis and design system architecture. Subject of study - methodological foundations, models, methods and information technologies for the realization of an architectural framework makroproektuvannya information systems. Thesis is devoted to the development of scientific and applied problem of creation of models, methods and information technology that generate the creating information system (IS) architecture description variant, the most efficient in terms of meeting the functional requirements of the Provider and the Consumer and requires minimal cost to implement. An improved service approach to the creation of IS, a concept and a set of mathematical models describing the set of system requirements at different stages of their formation, a mathematical model of pattern design of the IS requirements are proposed. On the basis of these results, models and methods to automate the work on formation of architectures of created IS describe variants are developed. Namely, the model of the architectural framework of macro design of IS, models complex that describe the syntax and semantics of the description of requirements for IS at the level of information and knowledge; model of formulated functional requirements for the IS at the level of knowledge; methods of forming representations of the functional requirements for the systems on the level of information and knowledge; the method of synthesis options descriptions of the created IS architecture and the model to describe the synthesis of rational architecture of the system. To estimate the amount of work on the creation of an IS based on the description of its rational architecture designed ontological points model and method for forming ontological points descriptions. The information technology of forming and analyzing of requirements for IS as a set of unified within the framework of the proposed model of the architectural methods, techniques and methods of using the complex of automation based on knowledge. The questions of the practical implementation of the proposed methods and models considered, their reliability and efficiency have proved.
