Ievlanov M. Methods, models and technology of information systems development under changing of requirements

The thesis is devoted to developing methods, models and technologies of creation of information system and its com-ponents, aimed at changing demands in the system, to reduce the cost of information system development under changing of automated enterprises structures and business processes. For the first time offered: meta models of information system formation; categorical model for the submission of a system-wide information space; model of synthesis operations of information system meta model formation; simulation model of processes of information extension between elements of synthetic meta model; methods of synthesis of information system functional structure configuration option; methods of identified meta model elements inadequacies removing. Op-eration models on information system information space ele-ments are improved. Have been further developed: informa-tion system model module presentation model; models of information system model module configuration option syn-thesis processes submission. The results have been tested during the development and modernization of information management systems of enterprises of various types.
