The paper describes the relevance of using software simulators in the operator training process. There is a problem of developing a multi-user software simulator based on web technologies in the paper. The set of requirements proposed for the developed solution, which are necessary for learning how to perform technological process operations and developing appropriate action sequences both in the instructor presence and without supervision.

The paper analyzes the available solutions and proposes the developed system architecture, presents its ER-diagram with key description points that affect its operation.

There is a simulator used by a teacher and a learner. There are differences between the training modes, including a mode, designed to learn emergency handling. To show the system capabilities, the authors implemented a few exemplary control panels for training in performing process operations.

The proposed solution has been tested as the «Gazprom Classes» project part. The main advantages of the proposed solution are the development simplicity and the capability to design the control panes with a visual interface.

Pattern control system

G.P. Vinogradov ( Tver State Technical University, Research Institute “Centerprogramsystem” (Professor, Head of Laboratory), Tver, Russian Federation, ph.d;

The intellectualization requirement of the artificial entities’ behavior makes us reconsider the logical
and mathematical abstractions underlying the construction of their onboard control systems.

The problem of developing such systems based on pattern theory is actual. It is shown that this ensures the effective experience transfer and ensures the theological approach compatibility and the causal approach.

There is a survey of the identifying problem and building pattern models’ one. There is a proposal to use four information processing positions for this purpose, and there is a development of logical inference method on patterns.

Computerized servicing of management systems and equipment according to their real situation is an actual line of research.

The implementation of such developments at the productions allows us to keep costs down to the preventive protective service and also to protect the afore-precaution of possible unscheduled downtimes. The key role
in solving this problem is supervision over the technical condition of a production technique, machinery, equipment. This implies the creation of a fundamentally new paradigm for building the monitoring system of the state assessment and industrial control. Incidentally, the use of artificial intelligence methods gives its efficiency factor.

The paper summarizes the description of the construction principle of the information monitoring system for condition monitoring of machinery and the industrial plant equipment. The paper substantiates the general requirements for monitoring systems.

There are the use case diagrams, namely: deployment diagrams, state diagrams, information model diagrams, and component diagrams in the paper.

The authors determine the basic software requirements for the designed monitoring system.

Implemented monitoring system software for an abstract industrial enterprise.
