The main graphic notations describing business processes are discussed. Advantages and disadvantages of these notations are indicated and recommendations on the efficient use of the notations and supporting tools under certain conditions are given.

The article concerns various ways of information systems acquisition. The authors investigate opportunities of using the service oriented approach for IT-architecture constructing. They apply fuzzy sets to account for the uncertainty arising when selecting IT-services within a service oriented architecture.

There is considered algorithms and methods of evaluation of best order of requirements implementation in software development from point of maximization of profit from the project. Software where are used the methods is considered. Algorithms and methods for calculating the best order of implementation of the requirements for software development in terms of maximizing the profits from the project are considered and the software тthat implements these methods is described.

Information management organizing features in service company environment are discussed. In terms of small business information management that can be interpreted both as in a broad and in a narrow sense is an important specificity due to the role and place of the owner in the control system. The features of information management in a small software business are identified.

Methodological bases of construction of structural and functional model of the entity organization are considered. Described and scientifically justified requirements for all types of accounting (financial, accounting, nomenclature) entity. The basic principles of operation and re-engineering the structure of the entity during the transition to the use of new technologies are determined.

IT education development technology based on standardized curricula at the international level is discussed. The analysis of the current state of international standards for training programs for bachelor’s and master’s degrees in information technology as well as recommendations on the use of foreign experience in the development of domestic IT-education system are given.

Each of approaches to developing programming curriculum has its merits and demerits. Even before the planning we should define whom we actually name «programmer »: what kind of work is he doing, how chooses vacancies, how defines his own profession? The «paradigm of the specialist» approach helps to answer these questions regardless of the specific technologies popular at present, employers and the historical period.

The conference was held at the Faculty of Computational Mathematics and Cybernetics (CMC) of Moscow M. V. Lomonosov State University. Issues discussed covered the areas of methodology and methodological provision of IT education, e-learning technology and modern IT in education, educational resources and best practices of IT education, scientific software in education and science.

This research examines the problem of input text on mobile devices with touch screen by people with visual disabilities. Existing methods analyzed and a new solution is suggested. The mathematical model of the input method is examined. The results of a comparative testing of the proposed method and the best of the existing input methods are presented.

The paper describes a new Internet-based environment developed and applied to study needs in further training of the teaching staff of schools of St. Petersburg in the 2010 – 2011 academic year.

The current state of halogen incandescent lamps and their features are discussed. The mathematical model of heat transfer and programming model for analysis and modeling of processes in halogen incandescent lamps are described.

The article deals with the basic concepts of spectral analysis to obtain a graphic image of an audio signal and especially the restoration of the distorted audio. Figurative analysis elements are used to reconstruct the signal as well as the comparative method of processing the current standard and graphic images.

CAD / CAE software for technological processes modeling is analyzed. The behavior of nanoscale materials in the complex channel dies was modeled with the help of software package Ansys taking into account the dynamic load factor. Computer simulation was used to predict the compaction process of new, little-known materials under the influence of applied loads.

We consider all pairs of groups G and H under the condition that their orders are not greater than 12. For Abelian group H, we obtain (up to isomorphism) via computer modeling, first, the group of homomorphisms of G to H and, second, the subgroup in H which is a union of the images of all homomorphisms. For non-Abelian H, we consider the similar constrictions, but this case is more difficult.

A method of of a domain model constructing when building a knowledge based system is presented. This model is based on theory of Birkgoflattices, and is formed in recent logic-algebraic approach known as formal concept analyses. The method was applied to the structuring and formation of logical rules for assessing water quality.
