Creation of the rules of multiphysical similarity by a trawl complex
Currently, one of the most important applied industries is commercial fishing. With the development of the fishery complex of the Russian Federation, the challenge arises of processing large data (this is the forecast of fishing, the exploitation of fishing gears, the behavior of hydrobionts, etc.). This article discusses the first steps to create a mathematical base and rules of multiphysical modeling to the trawl complex to develop methods for controlling the trawl complex using predictive modeling on a trawl complex. To solve this problem, we synthesized physical modeling of the control processes of the trawl complex using predictive modeling. Predict the operation of the trawl complex, namely the trawl in a difficult situation (storm conditions, side currents, emergency), or establish a schedule for the control systems, anticipate the behavior of hydrobionts in the area of the trawl's action - it is possible to use predictive modeling to solve these and many other problems. This article presents the scale of similarity of physical quantities - the mathematical base for performing dynamic similarity of a complex technical system - a deep-sea trawl and a fishing vessel (trawl vessel).
