The study on the example of the choice of SAP UI Technology for the development of a subsystem of planning and actual time tracking has shown the proposed method of selecting one of the available technologies for construction of a subsystem based on a particular platform. The developed method includes the analysis of the features, advantages and disadvantages of each of the possible technologies and then a well-formalized decision-making process of choosing one of the technologies based on the analytic hierarchy process.

The paper proposes a model system for managing the process of formation of professional skills of trainees during exercise using a computer simulator. A distinctive feature of the proposed system models is the opportunity for the shortest time to achieve a high degree of quality development and skills by computing the integrated assessment exercise learners based on a number of quality indicators with different physical nature (using fuzzy set theory and the analytic hierarchy process) as well as full control of the dynamics of the development of skills in view of the gradual development of skills with repeated exercises under repeatability conditions (using mathematical models of iterative learning).

In this paper we propose a model to automatically obtain a comprehensive assessment of the level of formation of professional skills of operators of industrial-technological system, scientific novelty which, compared with existing, is the ability to relate the quality of some exercises on a computer simulator with different physical nature (time, distance etc.) with coefficients of development, are dimensionless quantities and therefore suitable for further processing. On the basis of the proposed model in the near future plans to implement algorithms, software and information support automated training system operators of industrial and technological processes.

In this paper we propose a model, the hallmark of which is the ability to automatically obtain a comprehensive assessment of the level of formation of professional abilities of operators, called a complex coefficient was calculated in the development and completion of learning exercises as a weighted average based on the weights of quality indicators used in this exercise, and the coefficients of development according to indicators of quality. Detail the features of the application of the analytic hierarchy process, which is calculated using the weights needed to calculate the complex factors of development. In the short term plan to implement algorithms, software and information support automated training system in accordance with the proposed model.

The paper proposes a model, based on which the automatic control of the dynamics of the development of skills based on the principles of iterative learning that provides the gradual formation of skills trained at repeated the exercise on a computer simulator under repeatability conditions. This is achieved by calculating the automated training system intermediate threshold of the complex coefficient with the development of mathematical models using iterative learning. The value of this ratio affects the formation of the control actions. In the short term plan to implement algorithms, software and information support automated training system in accordance with the proposed model of calculating the intermediate complex coefficient threshold of development.
