Invariant approximation and its application for integration of data-domain knowledge into metamodels
Changes of professional environment, caused by introduction of new technologies and techniques, create a necessity in continuous education and development of professional competences. In these conditions, managers and other company employees face the choice of methods and tools of personnel training. A business game is one of the most productive tools of business-education This paper elaborates the ideas embodied previously, which considered the conceptual approach to a toolkit creation for active training techniques in a form of competence-based business game studio. Competence-based business game studio is an ergatic system for development of professional competences, which are required to ensure organization’s business processes. Business game control is performed with the help of automate module, which executes the interpretation of expressions in algorithm logical scheme language. Unified business process is the input data for automate model construction. Unified business process is acquired from the information about company’s real business processes, represented in poorly formalized ways. Unified business process transforms into unified training business process, which includes possible business game trainee actions and information about input, output, administrative data and business process operation execution mechanism. The next step to automate model is the construction of scenario graph, which represents a more formalized description of unified training business process. Next, the administrating algorithm of the business game in algorithm logical scheme language is built. The paper considers the algorithms of transition between models that allow to automate the process of acquiring algorithm logical scheme in order to implement the business games scenario.
The article presents the guidelines of the competency modeling methodology invariant to subject domain, type of activities and psycho-pedagogical platform. The core of this methodology is systematics of the expandable metamodels adaptable to application conditions by profiling mechanism. The methodology is aimed at creating conditions for interoperability of systems and services that make up a digital education, dealing with competency description due to possibility of flexible selection of such interaction level, good information structuring and formalization, selection of competency description units repeatedly used in various contexts, as well as ontological approach. One more purpose of the methodology is preparation of grounds for realization of smart features of digital education technologies: adaptation, inferring, self-learning, anticipation.
The technologies based on applying a metamodeling and domain-specific languages are widely used at information systems developing. There are many different tools for creating graphical domain-specific language editors with a possibility of determining user’s graphical notations. However they possess disadvantages. The MetaLanguage system is designed to eliminate some of these shortcomings. MetaLanguage is a language workbench which provides creation of visual dynamic adaptable domain-specific modeling languages used in the development of information systems. In paper the approach to development of MetaLanguage DSM-platform is considered. Basic metalanguage constructions of this system are described. The mathematical multilevel domain model with usage of pseudo-metagraphs is constructed. Definitions of the graph and metagraph are given. The algorithm of vertical models transformations is described. The architecture and implementation of the development environment of MetaLanguage toolkit is presented.
One of the challenging issues of Enterprise Architecture (EA) in large companies is organizing processes of baseline EA development and change management under conditions of steady change that implemented and changed IT solutions introduce. The research paper describes the approach of developing and keeping relevant baseline EA description together with IT project teams using Solution Architecture models. The method is in process of implementation in one of the leading Russian oil and gas companies Surgutneftegas
The paper suggests a formalized business game description technique, based on the information about company’s business process. The technique include sequential building of a model set that enables to acquire business game execution scenario.
