Methods of analysis by the criterion of functional completeness long been successfully applied in
various domains. However, never before this technology is not used for comparison sites of searching
for wholesale suppliers. These investigations have produced unique results and make evidencebased
conclusions very useful for market participants of wholesale deliveries. The solution to the
problem of selecting the best from the variety of Internet sites search wholesale suppliers is a difficult
task. In article on the basis of real evidence about the realized functional operations analysis
and the choice of optimal business solutions. Compiled a list of the functions available on the market
sites search wholesale suppliers. Systematic information on the composition and functional completeness
of existing sites search wholesale suppliers and their projects. It is possible to quantify the
degree of conformity of a particular system requirements to functional completeness. Ranked sites
search wholesale suppliers according to the criterion of functional completeness. Excluded from the
scope of software products, which are not implemented the required functions. There are groups
of software systems, such as ongoing functions. Provided support to select the desired component

This article explores the differences of traditional CRM (Customer Relationship Management) systems
from their network analog — cCRM (Cloud Customer Relationship Management). It considers
features of the «cloud solutions» related to the traditional management systems of interactions with
customers. The history of marketing relationship with customers was also considered in it. The article
was focused on solving the following tasks. The demarcation of the concepts CRM and cCRM was
realized. The specificity of the cloud customer relationship management was investigated. Trends in
the use of network CRM-systems were analyzed. Deploying activity on the use of cCRM — system
in enterprises was conducted. The life cycle of the cCRM concept realization process on the enterprises
was considered. Elements of the cloud customer relationship management strategy were
highlighted. VCRM (virtual customer relationship management) features were analyzed. The levels
of cCRM systems’ implementation in enterprises were taken into account. The steps and factors for
a successful integration of cCRM-system were considered. The estimation algorithm of CRM — system
and the way of cCRM integration were proposed by the authors. Also this article carries out the
analysis of ERP systems (enterprise resource planning systems) and analyzes the advantages and
disadvantages of their integration with business entities. The authors consider the transformation of
enterprises’ business models, which related to the growth of business processes’ electronization.

Also in the gas industry introduced information-measuring system of gas distribution point. The
system provides data acquisition from geographically distributed points on the following parameters:
the gas pressure high or medium pressure at the inlet pipe, flow, pressure and temperature of the
gas dispensed to consumers, gassed object, control and emergency operation of unauthorized access
to the facility. Based on the results in the thesis organized serial production of a new generation
of cabinet distribution points at Novomoskovsk factory of «Elektrotsentrmontazh.»
Developed and implemented information-measuring system crane nodes, implemented with regard
to the crane in service nodes of the Moscow ring pipeline branch of «Gazpromregiongaz.» Implementation
of information-measuring system crane nodes allowed to increase security of supply
by the operation status control valve stations, which had previously been tested through periodic inspections
and removal of process parameters staff in manual mode. The validity of the use of GSMcommunication
due to the distribution valve stations over a large territory and the absence of any
other means of communication. In addition, the task was complicated by the fact that most of the
valve stations of the Moscow ring gas pipeline network has no power. This required the development
of intelligent information-measuring unit with a small power supply and solar powered.

Integration of information and production technology has reached such a level that it is often impossible
to understand where one ends and another begins. In many organizations, the scale and
pace of investment growth in the IT consistently higher than investments in all other spheres of life,
with the result that not infrequently the IT assets of organizations are beginning to dominate the productive
assets. This scale and dynamics of development of information technologies requires proper
organization of management. Process development, adoption and implementation of administrative
decisions in the field of information technology have a certain specificity, due to a high degree
of virtual object management, multi-stakeholder in the implementation of administrative procedures,
which are used at the same time their professional languages. As a result of management decisions
produced in this industry are highly subject variability, uncertainty and unforeseeable consequences.
This article discusses the features of IT in modern conditions, and proposes an approach to the assessment
of the level of organization and management processes in the context of the latest achievements
of economic science in organizational management.

This article presents the results of research evaluating the positions of the Moscow State University
and the Saint Petersburg State University in the world university rankings by 2020, which is based
on the use of the neural network methods of clustering. The relevance of the chosen research topic
due to implementation of the May 7th, 2012 Presidential Decree N 599 which requires that 5 Russian
universities were join the world’s leading 100 by 2020. The method of clustering based on the selforganizing
Kohonen maps allowed to obtain the following results. The development program of the
SPbSU from the point of view of getting into the top 100 world universities has an insufficient value
of performance indicators and does not include a number of indicators that affect moving up in the
international rankings. The program of the MSU gives some chances to get into the top 100 but it is
necessary to fulfil additional recommendations, developed on the base of clustering model, which
can improve the performance of MSU. In particular MSU recommended to increase indicator Res income
/ Acad staff by 50 thousand USD relative to targets, specified in the development program.

The article is devoted to one of the problems associated with finding reliable information using
authoritative sources on the Internet — the SPSU Business Informatics’ students are training to solve
similar. The examples show that the effective solution of this problem requires the using of different
scientometric services: both the domestic eLIBRARY. RU and its Russian Science Citation Index,
and the Google Scholar as an alternative. At the time the work was sent to the Journal of Applied
Informatics the comparison was not in favor of the domestic resource. However, due to the RSCI
project within a short period the eLibrary’s tools for building database of scientific publications have
grown significantly and the opportunities to improve the quality of scientometric information become
real — see Yurkov A. V. APPLIED SCIENTOMETRICS: eLIBRARY. RU vs GOOGLE // Vestnik RUDN,

techniques of information systems’ software configuration to customize them for the field of implementation.
The main object of study is the data model of typical corporative information system. The
basic method for analysis and data presentation is object-oriented approach. There methods and
technologies to tune up the different software components are described according to the formal description
of their structure and interaction. The article is illustrated by UML-diagrams, tables and visual
schemes of object model’s elements. There are practical examples of the popular modern information
systems are presented. The elements of user management policy’s rules are discussed. The aspects
of the interfaces’ design and tools to enhance information systems’ functionality are analyzed. Some
attention is paid for COM-technology as a method to deal interaction between desktop information
systems based on Windows-platform. There is a discussion of the criteria to choose tools for software
development in case of realization new functions. There typical list of obligatory and optional components
and services of multiuser corporative information system is presented. This material could
be used as the practical guide to prepare for processes of software design and implementation.

Article uses XML-processing documents in situationally-oriented databases based on dynamic
DOM-objects for the task of generating personalized documents. The paper proposes a dynamic
model SOBD providing specifications and new elements to create a finished electronic documents
based on the Office Open XML blanks prepared by means of word processors. In the states of the
dynamic model blanks are generated using information from XML documents SOBD server web application.
The model in this paper allows the specification of routine operations to generate documents
at a higher level of abstraction, using the syntax model SOBD. The article shows the graphical
equivalents, and text tools introduced in the dynamic model and interpreted using the interpreter
embedded dynamic models for solving the problem of generation of documents. Interpreter embedded
dynamic models works with documents Office Open XML, using the technology of dynamic
DOM-objects, while the resulting documents have ways of representing docx and vdx. The work
looks at ways to specification of sources and processing XML-based data dynamic DOM-objects
bound to the states of the dynamic model. Proposed to implement the model on the platform PHP
using blanks docx and vdx.

Information security |

Although, both malware and security software already exists for several decades, there are still
no correct definitions for «malware» and «anti-virus».
Sometimes existing standards and regulators’ documents show completely opposite approach
to terminology in this field. A fundamental difference between «anti-virus» and «anti-virus protection
system» has not been defined — as a result, the anti-virus is assigned functions which this subsystem
cannot perform even theoretically.
Lack of proper terminology makes it impossible to work out the requirements to the anti-virus protection
system in whole as well as its components — current standards contain points, which at least
do not raise the level of security, but increase expanses of companies and organizations.
As a result, statistics shows that about 19 of 20 companies do not know anything either about the
role of the anti-virus in security system or the requirements that must be met by products which are
supposed to use — when drawing up requirements for the anti-virus subsystem, IT specialists rely
on set myths (e.g., claiming that all malware is created by anti-virus authors).
This paper attempts to develop requirements for the anti-virus protection system and directly to
the anti-virus as a part of the anti-virus protection system. The proposed requirements will allow companies
and home users to implement a reliable protection against the latest threats.

We consider the method of conditional optimization of solving of multi-objective task about appointments
on the assumption that the number of candidates is equal or more than the number of vacant
positions. Whereas eligibility assessments of task is unclear and is based on the judgment of experts we
must use elements of fuzzy sets theory and the fuzzy mathematical programming. In our problem the
optimization with interval parameter is supposed the solving of two tasks of mathematical programming
with upper and lower value boundaries. In both tasks, as the objective functions are used the total score
penalty for non-compliance of subjects (candidates) and objects (appointments) for each criterion.
The meet of two solving is general solving of optimization problem. In this paper we use interval
analysis and interval discrete optimization with Boolean variables, which determine appointment matrix.
The Hungarian Method for the assignment problem was used for solving of optimization problems.
An appointment matrix must provide the minimum of value of difference between requirements
to candidates for appointments and requirements to appointments. It should be noted that it is not
always the intersection of the sets of solutions to both problems, and then the task has no decision.
In this case the problem should be solved on the basis of indistinct intervals, but the solving will be
received in the form of an indistinct appointment matrix.
The results of solving of optimization problems are compared with results, which are received on
base of fuzzy binary relations ( (max-min) — composition and (max-prod) — composition).
This comparison is necessary for more reliable conclusions about the selection of candidates

The analysis of social engineering systems allowed to build fuzzy cognitive model of assessment
of its man-made elements to arrive at an informed judgment about the need for control actions to
bring the State of the social subsystem to the specified level. The set of control actions is implemented
through the use of institutional mechanisms, motivation and information management. You must
ensure that the level of motivation is not greater than the optimum value, and the intensity of institutional
measures was below critical. To calculate the value of concepts at the lower levels of the hierarchy
model can be used as an additive vector measure up, because in this case, the values of some
concepts can be offset by other values. For the top level of appropriate application of convolution,
because the multiplicative if at least one of the concepts of {«level of motivation “; «Psychophysical
capabilities; «Competence»} «variable linguistic factor» is set to «Low», then the integral evaluation
of the level of effectiveness of the man-made element should be taken as equal to «Low». Evaluation
of the concept of “ Level motivation» may correspond to the values of the negative term-many
of the linguistic variable. Assessment of the status of the subject in this case will also take «negative
» values. Content that can be interpreted as the potential destructive impact of man-made element
on the system-«insider threat».

Develop and implement programs of industrial production is a step by step procedure perform one
or more processes. Demand program is executed on the basis of both the actual statistical data and
simulation results. Modeling is necessary due to the fact that not all the parameters of governmental
processes are known with a satisfactory level of significance. It uses various methods of modeling.
Most process design engineers are not able to create a mathematical model for the process analysis.
In such cases, combined models are used: a simulation model of discrete control systems engineers
is used, and the physical, chemical and other create products processes are represented
by analytical mathematical model. Both are components of a complex model, and performed in the
same virtual time. As a result of simulation obtained all the missing process parameters are measured
their confidence intervals. Next, engineers must choose the optimization method for the production
program created, and can two opposite situation. First: the response surface obtained in the simulation
can be approximated with reasonable certainty by means of linear or nonlinear mathematical
form. Then, it is theoretically possible to use linear programming, nonlinear programming and gradient
methods. Second: the response surface did not found in the simulation. However, there are
simulation results that can be used to produce versions of the program. In this case remains one
method available: dynamic programming. This article describes the combined using of simulation
and dynamic programming to optimize production programs.
