Abstract: the article is devoted to the issue of increasing the efficiency of earth-moving machines by combining the control loops of various processes through the formation of a complex criterion that allows one to evaluate the simultaneous influence of various parameters on the efficiency of the working process of an earth-moving machine using the example of a chain trench excavator. The working process of a chain trench excavator with an automated device for controlling the position of the working body in the transverse plane is considered. The contours of control of the position of the working body in the transverse plane and the speed of movement of the chain trench excavator corresponding to the considered work process are presented. As a result, the factors influencing the efficiency of the working process are considered and the efficiency criterion is substantiated, which makes it possible to determine the optimal parameters of the operating body control device in the transverse plane. The result of the research was the analysis of the compiled simulation model of the working process and the theoretical research carried out. Any model is a kind of dependence representing the output value on the input input. The need to improve the device for controlling the position of the working body in the transverse plane has been confirmed; it should be confirmed by comparing the values of the output parameters of the investigated mathematical model with and without using the device for controlling the position of the working body of a chain trench excavator in the transverse plane.
