A solution which meets both requirements is robotization of production processes, i. e. replacing human labour with the work of industrial robots on the positions where tasks are monotonous, onerous or dangerous. The paper presents the economic analysis of the use of robots in production processes, as well as its technological conditioning. On the example of robotization of processes in the enterprise producing semi-trailers, the method of calculating the re-turn on investment was presented and an analysis of the labor costs of the worker and the robot at a given workplace was made.
