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

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.
