“…After that, the model was modified (Fig. 6) for further research, namely, to find the values of the coefficients of the PI controller [23], [24], [25] which bring the transient process of a real system with a transport delay as close as possible to the transient process of a system in which there is no transport delay [26,27]. Taking into account the peculiarities of the control object, the search for optimal coefficients of the PI controller, which would provide the desired characteristics of transient processes, is proposed to be performed by minimizing the deviation of the real transient process from the target.…”

Today, automation occupies a leading place in most branches of modern society, in almost all types of industry and economy. One of the main tasks of designing modern automatic control systems is the realization of high indicators in terms of accuracy, control range, and speed, taking into account the features of the control object itself. The purpose of the work –researching the microprocessor system of automatic control of the liquid level by means of computer modeling, taking into account the transport delay, the nonlinearity of the control characteristic of the pump and the presence of an insensitivity zone. To achieve the goal, the following tasks were solved: a computer model of a closed microprocessor system for automatic control of the liquid level wasdeveloped, taking into account the nonlinearity of the characteristics of the pumping unit and transport delay; a number of experiments were conducted to find the values of PI-regulator coefficients that bring the transient process of a real system with a transport delay as close as possible to the transient process of a system in which there is no transport delay; search for optimal values of the coefficients of the PI controller by minimizing the functional of the root mean square deviation of the real from the specified transient processes. As a result of research, it was established that the minimum points of the functional for the control signal and the liquid level do not coincide. At the same time, at the minimum point of the functional for the liquid level, a larger amplitude of oscillations of the control signal is observed, and at the minimum point of the functional for the control signal –an increase in the duration of the transient process. Therefore, the final decision should be based on the selection of priorities or optimal ratios between the speed and wear of the equipment, which is due tothe instability of the control signal.

Nowadays, information technology plays a significant role in increasing the efficiency of any company by focusing its attention on market trends, reducing and increasing competition for maximum profit. Based on the results of the analysis of scientific works, the author concluded that the existing information technologies in project risk management can be partially applied to manage the risks of IT projects, taking into account threats and opportunities. Therefore, this study is dedicated to solving the scientific and practical problem of developing information technology for risk management in such projects, which would consider the impact of threats and opportunities. The developed structure of the information base of the integrated management of threats and opportunities in the IT project will make it possible to implement risk management models and methods toensure the accumulation of statistical and expert information on the management of threats and opportunities. The structure of the information technology of integrated management of threats and opportunities in the IT project, as well as the scheme of its implementation, have been developed, which in turn will enable the project manager and his team to implement the relevant models and methods developed by the author in order to ensure the successful and timely implementation of the project to meet the needs of project stakeholders. The given algorithm for filling the information technology of integrated management of threats and opportunities in the IT project will allow managing risks taking into account threats and opportunities in accordance with the developed models and methods of integrated management of threats and opportunities in the IT project, which differs from modern approaches to risk management in project management methodology and programsand will reduce negative impacts and take into account positive impacts in such project. Thus, the obtained results make it possible to increase the effectiveness of risk management in IT projects, taking into account the impact of threatsand opportunities on them.
