Formalization of implementing a release cycle of electronic periodicals
Engineering Education # 11, November 2013
DOI: 10.7463/1113.0658430
This article presents analysis of a typical process related to implementation of a release cycle of electronic periodicals in a publishing house of a higher educational establishment. A set of main components that represent various parts of the publisher’s organizing structure and affect the operating behavior was determined. A process of maintaining queries from users by editors, reviewers, and bibliographers was considered. As a result of the conducted investigations, it was shown that the law of inflow of publication queries in an electronic periodical was the simplest one. Parameters of that simplest inflow of users’ queries were also determined. A formalized scheme represented in the form of a closed-loop querying system was proposed for description of a typical process of the release cycle of electronic periodicals.
Approach to calculation of weighting coefficients of experts’ rank assessments when selecting a development option for an information system
Engineering Education # 08, August 2013
DOI: 10.7463/0813.0580272
An approach to calculation of weighting coefficients of experts’ rank assessments, which is aimed at improvement of processing results of an expert survey, was proposed. This approach was designed to increase the concurrence level of experts’ opinions within a formed working group. Weighting coefficients are calculated either considering known numerical values of experts’ experience levels or on the basis of experts’ rank assessments produced from a test assignment. Recommendations on formation of a competent working group of experts who belong to the same school of sciences, as well as rules for using the normalized rank system, are at the heart of this approach. An example that illustrates efficiency of the proposed approach was presented in this paper.
Approach to increasing the level of consistency of expert opinion when selecting the variant of development of the data processing system
Engineering Education # 06, June 2013
DOI: 10.7463/0613.0574220
The authors propose a new approach aimed at formation of an expert group and improvement of polling organization for this expert group in order to obtain relevant information when selecting the best variant of development of the data processing system. The specified approach is based on the recommendations on the formation of a competent working expert group; rules for using a standardized rank system; recommendations on organization of expert-polls; rules for processing results of these polls; recommendations on result adjustments for certain experts of the working group aimed at the increase in the level of consistency of expert opinions. An example that illustrates efficiency of the proposed approach was presented in the article.
Approach to selection of a way to upgrade a LAN server
Engineering Education # 02, February 2013
DOI: 10.7463/0213.0535392
This article describes methods of decision-making theory which allow the decision maker to analyze various promising ways of upgrading a LAN server in detail and chose the best one; these ways are selected by a working group of experts. Recommendations are proposed on use of given methods in practice. A wide range of server’s operating parameters is taken into account along with nameplate engineering data. Practical guidelines on numerical composition of initial promising variants of upgrading a LAN server are also given. An example that demonstrates potentials of the proposed method is provided in the article.
77-30569/380497 Analysis of approaches to password system selection for protection of LAN servers when connecting Net users
Engineering Education # 03, March 2012
This article deals with the analysis of approaches to the formation of password system for protection of LAN server when connecting user network. Based on the demands of information security, main functions of password system for protection of server were identified. Set of main components of password system was determined; it consisted of length of password, password’s alphabet, password’s expiration date, unicity of password and variants of password’s blocking modes. Analytical expression for evaluating the required length of password, which guaranteed the certain given level of probability of guessing password considering speed and time of guessing, and also the alphabet of password, was presented in the article. In order to provide the required level of information security, practical recommendations on the formation of password system for protection of LAN server when connecting user network were given.
Analysis of approaches to formation of expert group membership focused on preparing and making decisions.
Engineering Education # 05, May 2012
DOI: 10.7463/0512.0360720
 The article considers the analysis of existent approaches to formation of quantitative and qualitative membership of decision-making working group. The author presents a review of approaches focused on selection of quantitative membership of expert working group. Analytical expression allowing to determine boundary values of quantitative membership of expert working group was obtained by way of this review. Estimation of competence of both single expert and the whole group was considered and a set of overall indexes for competence estimation was proposed.  The author gives recommendations on organization of expert groups producing coordinated, high technology and cost effective decisions.
