This paper proposes a new approach to the evaluation of investment attractiveness of innovative projects in the linguistic uncertainty caused by the nature of qualitative criteria to be applied. The authors propose an economic and mathematical model that supports decision-making about the level of investment attractiveness of the project that is based on the use of the mathematical apparatus of the theory of fuzzy algebra and implemented with specialized package Fuzzy Logic Toolbox in the system MATLAB. The advantage of using this model is the ability to formally describe the knowledge of experts and professionals in selecting strategic guiding economic and production structures, in addition to evaluating the economic benefits of the project semi-structured assessment of social utility and environmental safety.безопасности.

The article considers the numerical solution of multicriteria optimization problem of capital structure, which was formulated in the previously published article authors. Model of the problem is modified to suit different scenarios of financial and economic activities of the organization in the forecast period. On the basis of the data of real financial statements algorithm its solutions implemented in the Maple using the guaranteed result in the normalization criteria.

The article discusses the construction of an effective management system IT outsourcing company. Flow method traditionally used the organization of processing customer requests; however, in conditions of diversity of IT infrastructure requires a clear allocation of roles and responsibilities within the company. Shows the adaptation of ITIL process models for specific queuing customers and developed a system of motivation.

The paper discusses the problem, arising in the educational process of training on Information Technology — is it possible to choose the «optimal» programming language, suitable for all programming tasks, easy to learn and use, and guarantees excellence? Professional tasks that require programming skills for specialists in Applied Computer Science are considered. Programming languages and development environments (or specific implementations of languages) that must be included into a «set of optimal programming tools» for specialists in applied computer science are compared.

The problem is to construct the differences of LaTeX documents. Each document is represented as a parse tree whose nodes are called tokens. All of the text is splitted into fragments whose boundaries correspond to tokens. The map of the text fragments and the corresponding map of characters is constructed. Tokens, that chars are all deleted, or all inserted, or all not changed, are selected. The map for the trees formed with other tokens is built using Zhang-Shasha algorithm.

The completeness and accuracy of the information content obtained by means of topographic maps, allow to solve a variety of regional economic, technical and environmental objectives and the civil protection tasks. System analysis of the rapidly changing situation in the solution of such problems requires to use powerful simulation tools. One such tool is a general-purpose simulation system Actor Pilgrim, which, unlike the other is uniquely modeling the financial and economic processes, and it does not need to acquire specialized geographic information systems. Technological properties of the GIS software modeling system presented in this article.

This approach proposed to the study of social-engineering systems to meet all their basic features. Blurred structure of social engineering system reflects the fuzzy cognitive model; Fuzzy connection effectively evaluated using weights Fishburne; «blur» element values system and its functioning is overcome by introducing linguistic variables and their term-set fuzzy classifiers.

Currently an enormous number of databases on inorganic substances and materials properties exist that contains multidirectional information. Modern multifunctional devices development requires knowledge of a diverse set of materials properties. That makes the integration task of databases in the problem domain of great importance. The article is devoted to questions of integrated information system on inorganic material properties creation.

In November 2013 marks the 50th anniversary of birth of the term «informatics» in Russian the scientific literature. Professor of the Moscow Power Engineering Institute Fedor E. Temnikov published the article “Informatics“ as a polemical notes. The informatics seemed to him as integral scientific discipline that consists of three parts: 1) the theory of information elements, and 2) information processes theory, and 3) information systems theory.

The article describes the main characteristics of the scientific direction «artificial intelligence» and considered them the values that define this research area. Some ways to clarify and formalize the boundaries of scientific research directions are suggested. Formulated conclusions, which, according to the authors, restrict the flow of scientific research in this direction.
