The questions of the trajectory choice in the of Smart-education environment are discussed. The authors give the approximate content of a possible education trajectory. The article offers the technique of the education trajectory choice based on the decision-making support methods. The specified technique allows using both expert’s knowledge and experience in various fields of the organization and ensuring educational process, and the requirements of students. The article considers both group and individual decision-making methods. The authors prove the method choice for the task solution. The article shows an example of the minimum distance method application for the expert’s opinions coordination while choosing the alternative educational trajectories. The example of the hierarchy analysis method application while choosing one of the alternative educational trajectories recommended by experts is shown. The offered technique allows to automate the process of the most rational education trajectory choice and to reduce decision-making time and costs.

The local networks development is one of the most frequently solved today tasks in the field of information technologies. The article considers the main stages of the local computer network development as a number of separate multicriteria partial solutions of selection tasks. We propose a new approach for the base project variant selection and for private solutions, based on the methods of the decision-making theory. The authors detail the decision of these problems on the basis of the analytical hierarchy method and the ELECTRE method. The article describes two usage examples of these methods for the solution of a problem of types of communication lines selecting on user's criteria.

The paper shows an incompleteness of theoretical foundations of the Computational Semantics branches called Semantic Role Labeling and Frame-Semantic Parsing. This situation is a consequence of a seeming lack of a semantic formalism allowing to describe semantic structures of complex sentences and discourses pertaining to arbitrary application domains. It is concluded that the theory of K-representations (knowledge representations) provides a formalism of the kind, determining a new class of formal languages — the class of SK-languages (standard knowledge languages). Some new expressive mechanisms of SK-languages are illustrated. The central ideas of a method of semantic parsing of natural language (NL) texts proposed by the theory of K-representations are set forth. The method employs the class of SK-languages for constructing semantic representations of texts. The final part of the paper considers the application of the method to designing NL-interfaces for software management. A file manager with a NL-interface NLC-1 (Natural Language Commander — Version One) has been developed, the system is implemented with the help of the functional programming language Haskell.
The paper focuses on simulation of complicated projects, associated with developing of socio-economic, organizational and technical systems. Few types of complicated projects are determined: projects with few possible outcomes, repeatable projects, and projects with few possible ways of implementation. Combined cases with certain combination of the factors of complexity may also be considered. The purpose of the research is to determine key characteristics of complicated projects, and to develop recommendations in the field of their discrete-event simulation. For illustration of practical application of the models, Arena software, as a popular and approved tool of discrete-event simulation, is applied. A set of models for different types of complicated projects are presented. Each of the models include detailed description of appropriate Arena modules, their functions in the model and their relevant parameters. The models and related recommendations advanced in the paper are applicable for assessment of implementation terms and consequences of development programs with complicated projects.
This article aims at the improvement of the engineer training quality in the field of "computer Science and engineering" using on-line and blended learning technology. We consider studying of modern computers architecture as an example. The complexity of the modeling object, the multi-faceted process of studying the computer architecture, the limited period – are the factors that determine the difficulty of the problem. A computer simulator allows you to explore the stages and features of the calculation process in dynamics with the necessary detail. It can't be done any other way. Also, computer modeling creates a risk-free environment that allows you to safely and repeatedly apply and analyze possible scenarios, decomposition of computer nodes and configuring its components for different modes of operation. This is either impossible to perform on real devices or may result in computer failure under students’ inept actions. The paper discusses the problems of the computer units and devices simulating, the requirements for models in terms of solving educational and research problems. We propose a structure of the simulating complex, visualization methods of computer architecture components and principles of computer system device’s operation, algorithms descriptions of the modeling programs.
Since the computer architecture implies a whole complex of concepts, including functional and structural organization, software and hardware interaction algorithms, the considered simulating complex consists of several simulators: step-by-step operation of the superscalar processor core; cache coherence protocols in multiprocessor (multi-core) systems; algorithms for fast address translation with the help of Translation Lookaside Buffer (TLB); various technologies for multithreaded data processing; pipeline processing of the machine instructions stream; memory paging algorithms; cache mapping algorithms; cache replacement algorithms; etc. The main functions and features of each model are considered. An important advantage of the proposed simulating complex is the ability to vary the parameters of models of specific computer devices, which makes it possible to explore the resource/time characteristics of data processing by computer system devices.
