Kovalyov S.M., Kovalyov V.M. Modern methodologies of business processes description

Classical DFD and WFD standards include a set of symbols or notation to describe a business process. Many other business process description languages and procedures currently exist worldwide. Despite their differences (determined basically by diagram names and the available object types) they are practically identical and demonstrate slight modifications of the classical schemes. The paper discusses modern languages for business processes description such as IDEF 0 and DFD in Gane & Sarson and Yourdon-De Marco notation, IDEF 3, ORACLE, and BAAN.

Pertsovsky M.I., Yevtikhov M.G. Complementary type virtual instruments, protocol analyzers and `visual defaults`

The paper classifies virtual instruments and discusses their programming concepts. The ideas are exemplified in a VI extending the functionality of C9-8 oscilloscope. TstKop software is discussed that is a utility for supporting the general use channel controller`s driver. The ideas presented are quite simple but they concern the underlying concepts of VI programming and imply future development. The paper addresses the analysts who design measurement automation systems, VI programmers, and everyone else interested in VI problems.

Pavlyuchenko A.D. Manufacturing processes analysis based on Invensys Wonderware InTrack toolkit

The paper discusses 3 variants of analytical industrial applications design using Invensys Wonderware InTrack toolkit and IndustrialSQL Server real-time database for MES-level systems development.

Borzakova M.S. Longhorn platform from Ampro Computers, Inc.

The global market of embedded computer systems for critical applications is extremely small, and the number of participants is limited. Important application areas such as transportation, chemistry, aircraft instrumentation, and power industry where the highest quality and reliability are to be ensured with a small number of manufactured and purchased modules and systems become nowadays a battlefield of embedded system vendors. The paper discusses a new Ampro Computers, Inc. product line based on the Longhorn uniform hardware platform.

Vorkunov O.V., Takhavutdinov R.G. Sensor`s complementary error reduction in an automated temperature measurement system

The paper analyzes the effect of shape, material, and mounting of an intelligent temperature transmitter with an embedded ADC on the complementary measurement error in the conditions of free convection beside a vertical thermal pane. An automated measuring system is developed that displays sensor temperature and heating element`s power in real time. Numerical solution of fundamental impulse and thermal energy transport equations allows to build temperature and velocity fields for free convective air motion. The investigation undertaken results in the optimal sensor shape that ensures minimum heat flow deformation.

Shevelev Yu.V. Calibration equipment for contact temperature measuring devices

The paper presents the products of ETALON Scientific and Production Company for contact temperature measuring devices calibration. It shows that the whole spectrum of products enables to complete a high-performance calibration laboratory of industrial temperature measurement facilities for the whole contact thermometry range.

AAEON BOXER & Elipse E3 fanless control computer - a novel process control node concept

Industrial automation is gradually penetrating to small-scale production sectors who are not ready to buy expensive process control solutions or fail-safe industrial application servers. For this market segment, Rodnik Soft presents a new approach to lower level process control system design, a ready-assembled tested fanless AAEON BOXER control computer, and Elipse E3 preinstalled process visualization software.

Titov N.N., Prokhvatilov V.Yu., Krivonosov A.I., Trubitsin V.V., Tikhovsky V.M. Dispatcher`s Advisor software system for operating trunk power systems

The design concept of Dispatcher`s Advisor software system for operating trunk power systems is described. The system was developed by Khartep Company and applied since December 2003 as a part of the operation informational complex in the Automated Supervisory Control System of the North Ukrainian Power Grid.

Dianov R.S., Protalinsky O.M. A neuron network-based decision-making support system for gas condensate fields

During gas condensate field development it is often necessary to intensify gas discharge. The decision-making process to take place when planning the necessary steps is rather difficult and has no precise mathematical description. In view of this, an informational decision-making support system based on neuron networks was designed. A Kohonen network is used for selecting the intensifying action. The decision efficiency is predicted with the help of a three-layered perceptron on formal neurons with a single hidden layer. Neuron network architectures are developed, learning algorithms are described, and the NN models are validated. The developed decision-making support system enabled significant improvement of specialist labor productivity and the quality of decisions made.
