Analysts estimate that from 30 to 70% of the companies qualify the results of Enterprise Resource Planning (ERP) system implementation as partly failed (objectives have not been completely gained, terms and budgets of the projects have been exceeded, total cost of ownership of a system turned out unreasonably high, difficult maintenance etc.)
Along with above reasons we can note another two which are not often mentioned, but connected with the realities of operating enterprise:
transformation of the enterprise structure and the rules of its operation, which requires change of ERP-system configuration and consequently significant financial and time costs;
manual data input by the operator.
MES-systems (systems for process control) are intended to reduce or eliminate manual data input to ERP-systems. Such systems are intermediate between SCADA (Supervisory for Control And Data Acquisition) and ERP-systems. When solving the control problems at a certain level (department of power engineer, mechanic, technician, supply etc.) provided interaction with ERP they are able to minimize human factor influence during the data acquisition.
Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment ACS SRSM™ COMPACS® are MES-systems based on automatic acquisition and practical use of diagnostic information on the equipment condition in real-time mode.

Ensuring safe operation of potentially hazardous production facilities is inseparably linked with condition monitoring of equipment, rotating in particular (pump-and-compressor, energy, etc.). Nondestructive testing (NDT) method of vibration analysis is one of the effective and developing methods of condition monitoring of such equipment.
Since 1995 DYNAMICS Scientific & Production Center (SPC) specialists have trained the students of Omsk State Technical University (speciality "Devices, methods of quality control and diagnostics") to vibration analysis method of testing, and since 1999 they train the specialists of vibration analysis method jointly with the Institute of Radio Electronics, Service and Diagnostics.
Experienced specialists and teachers, the signal bases with actual defects, the possibility to control knowledge electronically in a terminal class by the tickets, laboratory facilities based on portable and stand diagnostic systems, and significant methodological groundwork – these facts characterize DYNAMICS SPC as the leading organization in the field of vibration analysis training that has already trained the specialists of more than 25 enterprises of chemical, petrochemical, oil and gas, mining, metallurgical and other industries.

Operation quality of traction electric engines (TEE) and wheel motor units (WMU) of locomotives in the field can be increased by improvement of maintenance systems on the basis of diagnostic activities for the purpose of more objective and reliable condition control of critical parts and assemblies of WMU, such as bearing assemblies, windings insulation, commutator-and-brush assembly.
On the basis of the analysis of influence of external operational actions and deflections of design and process variables of electromagnetic and mechanical character on TEE operation quality a diagnostic model of TEE and WMU operation quality in the field has been formed. In addition, we detected an effective set of most informative and distinctive parameters of condition diagnosing and performability monitoring.
The article presents the requirements for the system of vibration analysis and condition monitoring of TEE and WMU of locomotives in the field. The most efficient methods for equipment condition evaluation are presented, diagnostic features are specified, a block diagram of probing technologies of the locomotive section is presented, basic software modules of the system for vibration analysis of TEE and WMU of locomotives are described.

An adaptive algorithm for measuring and processing of the signals in a wide frequency range, which use pipelining of the channel selection at the lines level, at the level of analog-to-digital converter structure, and paralleling of the measurement processes at different lines, has been developed and realized in the article.
Application of these algorithms enables to increase the productivity considerably and to bring the frequency of measurement and diagnostics within the scope of a certain fieldbus up to 7,5 acts per second in case the selection length equals 400 ms and the hardware is absolutely self-supervisory. Consequently application of these algorithms enables reduction of time of response of statistical delta modulation to the change in diagnosed equipment condition.
Developed algorithms have been applied in the COMPACS® systems used at dozens of Russian enterprises. These systems have established a reputation as fast and high-reliability measurement complexes to solve the problems of diagnostics and monitoring.

Despite normal rotation frequencies and equipment degradation rates are relatively low there is still demand for equipping of mining industry machinery, which is most important for manufacturing process, with the systems for equipment condition monitoring. This demand is determined by the security requirements and significant reduction in costs of maintenance of the machinery equipped with the systems for monitoring and diagnostics.
There is positive experience of operation of stationary systems for equipment condition monitoring in mining and mining-chemical industry. Mining plants are equipped with the systems for condition monitoring including those based on the methods of nondestructive testing. These systems can evaluate technical condition of process equipment during operation and provide the personnel with the information on technical condition of process equipment in real-time mode, as in many enterprises of oil and gas processing industry.
The article deals with the approaches to condition monitoring of working machines of mining industry. As mentioned in the article, the use of technology developed by DYNAMICS Scientific & Production Center (SPC) using the COMPACS® systems enables application of the most significant process and low-charged equipment in the optimum way and cost-effectively. Fail-safety of the enterprise increases along with the decrease in the cost of fixed assets maintenance. That results in capitalization and increase of profitability of the company.

Fan plants for central ventilation of a mine are the most important element that ensures operation and safety of mine production. Long shutdown of the fan is utterly unacceptable because it may cause danger to life and health of the workers at the mine.
Reliable information on technical condition of the fans helps to reduce the probability of their sudden failure. It enables early planning of repair work and stand-by fan starting. Timeliness and reliability of the information helps personnel, which services the fans, to find a proper solution.
The COMPACS® system enables detection of fan plant malfunctions (bearing defects, imbalance, misalignment, unfastening) and violation of operating practices (aerodynamic defects that increase overall level of vibration loading on bearing supports).
Timely detection of developing defects enables to schedule preventive and repair work, which significantly increases level of equipment use. In addition the use of information on the fan condition enables reduction of the probability of a sudden failure and associated emergencies in the mine. Consequently fail-safety of the enterprise increases. All that leads to capitalization and increase of JSC "ALROSA" profitability.

In 1980s a lot of cryogenic tanks with thermo-insulating housing (GHK, CTK, TRZHK types) have been produced. Nowadays most of them have already worked for designated lifetime (20 years). However, it is still possible to operate these items for a long time. And it is important for most companies because new items are rather expensive.
In this connection it is necessary to carry out technical diagnosing and examination of industrial safety (EIS) of the equipment. The cost of technical diagnosing and EIS is much lower than the cost of new item, and their positive results enable extension of operation life of the equipment which has worked for designated lifetime. Therefore the development of the techniques for condition control of the vessels after their repair, after the assigned resource completion and periodically during operation (particularly by acoustic emission method of nondestructive testing) becomes a topical problem.
In terms of the gathered experience a standard program for technical diagnosing of cryogenic tanks and vessels, which determines conditions and basic requirements for acoustic emission control, has been developed. This program provides for pneumatic testing with acoustic emission maintenance and enables not to disturb the hermeticity of thermo-insulating housing. That enables significant reduction of costs of diagnosing, retention of the housing integrity and condition monitoring of the inner vessel on-site.
The developed method of cryogenic tank technical diagnostics enables condition monitoring of the inner vessel during the test and operation of the tanks.

Safe operation of the compressor units with reciprocating compressors (CU with RC) operating on explosive and noxious gases is possible only by continuous monitoring of their technical condition.
At most enterprises of oil-refining industry CU with RC are almost beyond their service life, and it is necessary to make an examination of industrial safety in order to prolong their service life. In addition, schedule-based preventive maintenance and repair are not economically feasible and efficient, and more than once it was proven in practice and examples of centrifugal equipment. The only way out is equipping of CU with RC with condition monitoring systems using various methods of nondestructive testing and process variables and transition to operation, maintenance of reciprocating compressors by their actual technical condition. Therefore, the development of methodology and systems for condition monitoring of CU with RC is a topical problem.
The article gives scientific definitions of condition monitoring, technical diagnostics, technical diagnosis, diagnostic feature; it presents the principles of monitoring system structure, data collection, data analysis and processing, time selection of the signals, spectral analysis, envelope analysis, trends, pattern identification, emergency shutdown and presentation of monitoring results.

The process of coking is widely used for processing of heavy still bottoms. It enables to improve the depth of oil refining and thus increase the enterprise profitability.
21-10/ZM unit releases through the complicated process involving hundreds of units of machine and columned-capacitive equipment. The failure of any element of a technological cycle may not only cause the decrease of quality and output but also result in emergency shutdown.
In order to ensure reliability of production it is necessary to know technical condition of equipment in operation, timely detect assemblies with critical technical condition and prevent emergencies.
Equipping of the machinery of Omsk Refinery with the COMPACS® stationary system enabled accident elimination. So-called sudden failures stopped. 'Suddenness' occurs in case of absence of the supervision over the processes of defects emergence or development, and consequently their growth to a critical level up until the accident.

The necessity of accident-prevention protection of powerful compressors and other unique equipment has never raised doubts of the experts. In order to ensure technological system tolerance for disturbances, including failures of process and pump-and-compressor equipment, it is necessary to trace external and internal factors that influence the system and characterize its technical condition.
In order to manage the system condition it is necessary to take technical and organizational measures. Equipment accidents at Omsk Refinery caused safety decrease, loss of efficiency and downtime of process equipment and thus inflicted economic damage, exacerbated environmental problems.
Under the circumstances in the late 1980s the company administration had decided to implement stationary systems for equipment condition monitoring and first of all stationary vibration analysis of machinery. The specialists of Minaviaprom engine research institute, who developed and implemented the devices and systems for vibration analysis of aircraft units, got involved in the work. Later these specialists formed the main body of Scientific Production Company "Dynamics".
