An overview of the software packages for technological modeling used for petroleum refineries is given. An optimization criterion, that allows determining the maximum yield of light oil products is received, as well as restrictions on the process parameters are established. The adequacy assessment of the initial data dependence according to the Fisher criterion is given. A mathematical model of the petroleum distillation process for low-capacity installations is obtained. The model can be useful at optimizing the variable composition and consumption of raw materials (petroleum) according to the selection criterion for light oil products, taking into account seasonal requirements for the quality of petroleum products. The use of the proposed optimization criterion and the mathematical model on small-capacity oil distillation units improves the efficiency of process units.\u0000\u0000Keywords\u0000sectional model, petroleum product, quality indicators, optimization, boiling point, potential fraction content, selection","PeriodicalId":309803,"journal":{"name":"Automation.

The results of numerical simulations show that the BP neural network optimized by the genetic algorithm can effectively eliminate a local minimum defect, which is easy to find in the original BP neural network, and has the advantages of fast convergence rate and high accuracy.\u0000\u0000Keywords\u0000BP neural network; genetic algorithm; local minimum defect; optimization","PeriodicalId":309803,"journal":{"name":"Automation.

The proposed mathematical model includes an information model of the ground and airborne segments operation for the approach system. The mathematical model of the ground segment implements the calculation of the CGS radio signals power level at a given point in space — the position of the UAV. The mathematical model of the onboard segment implements the determination of the UAV getting into the radio beacon coverage area and the calculation of the UAV deviation angles from the glide path line. The UAV dynamics model is considered as a set of pre-obtained trajectory points.
