The hierarchical Detailed Value Chain Model and the Elementary Management Cycle model of educational domain knowledge content updating are formally described in this paper, wherein computerized process measures are also proposed. The paper provides a method for updating the knowledge of the analyzed domain, referred to as the “enterprise domain,” based on enterprise modelling in terms of management information interactions. A method was designed, the formal DVCM and EMC descriptions of which are provided in the BPMN notation, allowing to develop a two-level (granular) model for describing the knowledge of educational domain management information interactions. In implementing this model and its algorithms in technological terms, a subsystem of enterprise knowledge has been created in a knowledge-based CASE system (computerized knowledge-based IS engineering), which performs the function of a domain knowledge database.

The problem of constructing an intelligent system for diagnosing heart valve disease is considered. It is shown that the diagnosis is established on the basis of the results of a standard examination, which includes anamnesis, laboratory data, electrocardiogram, echocardiography and Doppler examination. The use of hybrid neural networks of ensemble topology is substantiated for solving the problem. In order to show that the appropriate neural networks for composing an ensemble can be effectively selected from a set of available neural networks, an algorithm for structural-parametric synthesis of hybrid neural networks of ensemble topology is proposed. As for training component neural networks it is used Bagging approach. Accuracy and diversity were used as criteria. The structure of the diagnostic system for recognition of valvular heart disease is presented. The results of research of the developed software are presented. As for training component neural networks, the Baging approach is used. The structure of the diagnostic system for recognition of valvular heart disease is presented. The results of the study of the developed software are presented.

The paper deals with the problem of the requirements enhancement related to a particular problem domain. New requirements related with problem domain (user, customer study program) are elicited and compared with the old requirements which are documented before. The modified Value Chain Model (VCM-based) framework for the refinement of new requirements, assessment and enhancement of old system requirements is developed and discussed. Enterprise management information interaction is specified as an Elementary Management Cycle (EMC), linking enterprise management function and process by a feedback loop. A modified Value Chain and Elementary Management Cycle model was created to describe management knowledge updating process. Proposed hierarchical modified Value Chain Model and Elementary Management Cycle model allows to structure domain knowledge identification and updating processes.

The hierarchical Detailed Value Chain Model and Elementary Management Cycle model of educational domain knowledge content updating is formally described and computerized process measures are proposed. The paper provides a method for updating the knowledge of the analyzed domain, referred to as "enterprise domain", based on enterprise modelling in terms of management information interactions. A method, whose formal DVCM and EMC descriptions are provided in BPMN notation, was designed, allowing to develop a two-level (granular) model for describing knowledge of educational domain management information interactions. In implementing this model and its algorithms in technological terms, a subsystem of enterprise knowledge has been created in a knowledge-based CASE system (computerized knowledge-based IS engineering), performing the function of a domain knowledge database. This method is suitable to discover content related to the business enterprise activities and enterprise software development. The main outcome of enterprise modeling approach is the effectiveness of discovering of the deep knowledge, when education domain frameworks are applicable. A computerized management knowledge measure was created that can be applied not only in chosen subject area updating, but other areas as well, such as: the creation and updating of business knowledge bases, the development of BI measures by implementing knowledge bases, the evaluation of the fullness of accumulated repositories' content.
