Business information systems

Author: A. Volkov

Revue of aspects of implementation of process management in IT companies; the aims and requirements for technology modeling business processes, are considered a means of describing busi‑ ness processes. The examples of internal processes of IT companies and the processes of «cross‑linking» activities. Shown, how its optimization significantly affects the efficiency of the company, the process approach allows creating new and effective mechanisms, to reduce costs.

The task of the business process management system readiness level to informatization are proposed. It is proposed the verbal description of stages maturity with the multitude of partial quantitative criteria to reflect for this it propose the multicriterial examination by experts to take. The generalized methodics on base of multicriterial expert estimate are proposed that make possible the business process management system elements readiness level uniform to estimate.

Project management

Author: A. Mikheev

The article discusses the application of process management to financial management. The decentralized management of financial institution financial resources with the help of process approach is described. Traditionally, process management and financial management were considered as the independent areas of research. In this paper the recently appeared kind of process management which involves direct execution of business processes in a computer environment is applied to financial management area.

Performance management

In this article considered the application of methods of qualitative data analysis for creation of a research conceptual framework, specification of research purposes, tasks and questions, which it has to answer. This approach is applicable for a wide range of researches, well proves to be in the conditions of indeterminacy, capable to help with communication of scientists and customers, to plan the purposes of further researches.

Software engineering

Algorithmic efficiency

The article presents the results of development of models and algorithms of calculation of technical devices intended to reduce the vibration impact of the working medium on the piping of reciprocating compressor units. Models differ in that they contain the information structure of a piston compressor, the working medium, the physical properties of gases and allow via algorithms presented in this article automate the calculation of the design characteristics buffer capacities and diaphragms smoothing the pulsation of the working medium. Using the developed models and algorithms will allow to reduce expenses on designing systems for pipeline binding of reciprocating compressor units and will contribute to improving the quality of their expert assessment in the period of operation.

Information security

Models and methods

The basic principles for combining test checks of individual modules constituting the digital device into a single test program are described. Association of checks is conducted under incomplete information concerning reactions of the faulty device. Properties of optimum ordered sequence of checks in the test are formulated. Heuristic checks ordering algorithms are offered.

Currently an enormous number of databases on inorganic substances and materials properties exist that contains multidirectional information. The article is devoted to questions of accumulated data usage to find out regularities by means of pattern recognition methods that allow predicting formation of not synthesized substances and estimating its properties.

Simulation

Theory and practice

This article describes a software package for the large‑block construction of ships technological processes modeling for the possibility determination purpose of the production program and search «bottlenecks». Developed software package designed to create simulation models covering plant enlargement and saturation blocks, slipways production in shipbuilding companies and holding them for complex experiments. The tasks to be solved by using a complex, as well as tools of the initial data, the formation of a simulation model are described. There are ways to specify the experimental conditions provided to the user via the user interface. Some computational problems and conditions that affects on simulation results are rewied.

Actor modeling

The complex processes simulation, some dynamic characteristics of which are necessary to test not only in time but also in space, it is impossible without the use of topographical information pro‑ viding models and precise positioning of all test points to complex spatial objects on the Earth’s sur‑ face. The easiest task, which is solved by using computational geometry methods, is the definition of the object area. However, recognition of the items appearing in the modeling process belong to the list of these objects — is a dynamic task for which solving there are no universal methods. Below we consider some of such problems solutions.

Laboratory

Decision support systems

The problems of modeling tools create a decision support system for management of the budget for computer processing characteristics of the budget, expressed in the form of logical structures of natural language and representation of linguistic variables. Automaton constructed economic and mathematical models to solve the problem of generation of chains, which give qualitative assessment of the revenues and expenditures, as well as their recognition in a given formal grammar.

Mathematical models in economy

Author: Ye. Popova

This paper discusses the factors that are defining for the of human capital level. The study is based on time series. The regression function are represented for the main factors of human capital. In the future, these regressions used to predict the human development index. Some dependencies provide the possibility of scientific prediction; the time period makes it possible to verify. The functions typology is performed on the basis of regression types and determination coefficients. Some factors considered for groups of countries that use the same social model. The paper discusses the Continental and Scandinavian social model.

Point of view

Methodology of science

In this article the features of non‑uniform knowledge reflected in construction of models in the field of an artificial intellect are considered, and the description of the mechanism of a location on their structure is offered. It allows to express further work of the corresponding mechanism of a logic conclusion at program level.
