An approach of using of the DSM-platform MetaLanguage for integration of various modeling systems is presented. This tool allows to design visual domain-specific modeling languages and to create domain models with developed languages. The MetaLanguage system includes components for describing transformations of models from one formal notation to another. Domain-specific modeling permits various specialists to use concepts from different domains at creating and analyzing of models. An integration of DSM-platforms with tools of models analysis allows to involve domain experts, end-users in the process of constructing and analyzing of models; to reduce the complexity of models development; to fulfill research of models from various points of view with usage of various methods and tools.

At the process of creation and maintenance of information systems the model-based approach to the software development is increasingly used. This approach allows to move the focus from writing of the program code with using general purpose language to the models development with automatic generation of data structures and source code of applications. However at usage of this approach it is necessary to transform models constructed by various categories of users at different stages of system creation with usage of various modeling languages. An approach to models transformation in DSM platform MetaLanguage is considered. This approach allows fulfilling vertical and horizontal transformations of the designed models. The Metalanguage system support “model-text” and “model-model” types of transformations. The component of transformations is based on graph grammars described by production rules. Transformations of model in Entity-Relationship notation are presented as example.

The approaches based on applying of metamodeling and domain-specific languages are widely used in software engineering. There are many different tools for creating visual domain-specific modeling languages with a possibility of determining user’s graphical notations. However, these tools possess disadvantages. The article presents an approach to the development of language workbench that allows to eliminate some restrictions of existing DSM-platforms. The MetaLanguage system is designed for creation of visual dynamic adaptable domain-specific modeling languages and for models construction with these languages. It allows executing transformations of the created models in various textual and graphical notations. Basic metalanguage constructions of this system are described. The formal description of modeling languages metamodel used in MetaLanguage is given. The architecture of MetaLanguage toolkit is presented.

The paper describes an approach to semantic indexing of electronic documents based on ontology that describes the structure, type of document and its contents. In addition, existing ontology descriptions of documents are considered and the differences between the proposed multidimensional ontology from them are described. The solution of the problem of analysis of administrative regulations is described as an application of the approach. An algorithm for implementing semantic indexing based on multi-agent paradigm is proposed.

Creature questions of the mathematical, informational and programming support for the practice network community control are considered. Community mathematical model is proposed. This model utilization as basis for realization of the control system principal functions in the context of the participant interaction improvement and object community regions forming is considered.

These are the proceedings of the International Workshop on Petri Nets and Software Engineering (PNSE’13) and the International Workshop on Modeling and Business Environments (ModBE’13) in Milano, Italy, June 24–25, 2013. These are co-located events of Petri Nets 2013, the 34th international conference on Applications and Theory of Petri Nets and Concurrency.

PNSE'13 presents the use of Petri Nets (P/T-Nets, Coloured Petri Nets and extensions) in the formal process of software engineering, covering modelling, validation, and veriﬁcation, as well as their application and tools supporting the disciplines mentioned above.

ModBE’13 provides a forum for researchers from interested communities to investigate, experience, compare, contrast and discuss solutions for modeling in business environments with Petri nets and other modeling techniques.

Measuring the value of IT is always a challenge for investors. Market share for service oriented Information Systems (IS) is constantly growing and it creates the demand for methods of measuring the value of SOA-based IS projects. This research is aimed at adopting existing IT Project assessment methods to this growing demand. The work proposes the method that considers the fact that SOA-based IS deployment and evolution could be split in separate flows, one per service. It will allow usage of individual discount rate values per service since project risk values should be different for different services. It should make project value assessment more accurate comparing to existing methods which use the single flow for the entire project. This research also proposes Real Options for calculating the flexibility fraction of the value. The developed method was verified using own simulation model. Both developed method and the simulation model were applied to value assessment of a real-world project.

The proposed training manual is designed to prepare undergraduate students in "Computer Science" and in "Computers, complexes, systems and networks." The manual is designed to prepare students principles of computer networks and technologies used in local area networks. The principles of the construction of computer networks and telecommunications systems interconnection model systems used for networks, data bases, organization channels of analog and digital communication lines via wired and wireless environments principles transmission control information, coding and data compression technology of modern local organizations networks (Ethernet, Token Ring, FDDI, Fast Ethernet, Gigabit Ethernet, 100VG-AnyLAN), network equipment LANs. The manual can be used by students to prepare for the performance of laboratory and practical work on the course "Computer Networks and Telecommunications", "Networking" and "Administering Network Systems".

A general description is given of software products designed for econometric studies. Software packages Microsoft Excel, Stadium, SPSS, and MATLAB are considered in detail.

We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.

We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
