Ceyber-physical systems are advanced today. They represent the integration of physical objects and information systems using various types of detectors and sensors. The information obtained from such systems can be used to forecast the future state of the system, which makes it possible to predict the load or detect its decrease. This allows to make a decision on expanding the system capacity and elicit any problems during the operation of the cyber-physical system.

The paper proposes a technique for modeling a surge — the compressor line self-oscillating operational mode. The technique of constructing gas-dynamic characteristics of centrifugal compressors, artificially extended to the area of low flow rates, is described. The paper offers an example of computer simulation of the surge phenomenon in a natural gas pumping compressor line for the case when the operating mode is within the ascending section of the gas-dynamic characteristic plot.

Process mining is a promising method for investigating the various sequences of events that can be considered a process. When monitoring a large number of parameters, it becomes difficult to select parameters to assign them to the attributes of the event log format. The accuracy and information content of the resulting model and, as a consequence, the quality of the process analysis and detection of anomalies depend on the correctness of the comparison of attributes. The article discusses the features of the formation of event logs when processing data from heterogeneous sources.

The article discusses the problem of optimizing the characteristics of microelectronic objects in the transition from abstract virtual layout models of cells to their layout drawings in real design rules. Optimization of the characteristics of microelectronic objects is provided by an original layout compaction algorithm based on a virtual coordinate grid, which simulates the actions of a layout designer to reduce parasitic parameters.

The paper considers methods for determining the parameters of approximating distributed links used to describe the static and dynamic characteristics of hydrolithospheric processes, in which the filtration coefficients for spatial coordinates have different values. Using approximating links, the problem of determining the optimal number of wells is solved.

A frame model is described, which underlies moisture content operational assessment system functioning during its drying in drum drying installations. Drying plant equipment includes a variety of sensors that monitor the drying process. Failure of one or several sensors can have a negative impact on the drying process information content, but won't bring any effect on the dried alcohol stillage quality. Therefore, sensors groups are identified in a way to correspond states classes: failure-free operation, soft failures, medium failures, and sensors' hard failures. The frames of the created model describe equipment drying plant functioning states classes, and specific properties of each class are reflected in the slots containing the attached procedures for neural networks implementation that allow moisture content material estimation. The frame model allows to create adaptive sensors for material's moisture content operational assessment, taking into account equipment operation various states, making up the drying unit and its operating modes. The use of an adaptive sensor makes it possible to estimate alcohol stillage moisture content for all operating states with an error less than 2 %.

Paper presents the problem of parametric identification of processes of technological thermophysics based on the solution of inverse heat conduction problems under conditions of random disturbances. The solution of the boundary inverse heat conduction problems is sought, for which the method of parametric optimization of physically substantiated desired characteristics on compact sets of polynomial functions is used. The proposed approach is based on the alternance properties of optimal trajectories, optimizes the solution in a uniform estimation metric (using the minimax functional), and is the algorithmically accurate method. An increase in the intensity of disturbing factors causes difficulties in the direct application of alternance properties. An algorithmically accurate method has to be combined with additional algorithms that provide adequate results under conditions of bounded uncertainty of disturbances. As possible approaches, preliminary smoothing of information, control of an ensemble of trajectories satisfying the conditions of interval uncertainty, and the method of artificial intelligence are used. Using an exact analytical model, the combination of the minimax optimization method with algorithms operating under conditions of information uncertainty leads to regular solutions of the inverse heat conduction problem that are satisfactory inaccuracy.

The aim of the study is to develop a mathematical model of the methanol stripper as an object with distributed parameters. The relevance of this topic is due to the use of this technology in the process of low-temperature separation in order to reduce the loss of an expensive inhibitor of hydrate formation. As a result of the study, the correct assumptions, boundary and initial conditions were determined, a mathematical model of the object was developed in the form of partial differential equations. The transition from a continuous model to a discrete-continuous one is presented.
