In the article the features of application of logistic approaches of the organization of movement of the cable cars, as well as the method of selecting the cable car and the slopes at various characteristics of the operation of the complex. The results of experimental research on the network of cable cars of the mountain resort "Rosa Khutor"are offered. The paper uses the methods of monitoring the movement of passengers on cable cars by means of identification by ski pass and GPS

The process of profiling tubes with rollers was considered. The method of solving the problem was considered. The stress-strain state of the metal in this process was determined, the equations of relative deformations was given, the shear strain intensity in cylindrical coordinates are given for the case of a plane homogeneous deformed state. The stress state index was defined
Keywords: Pipe profiling, deformation, stress, flat pattern, mathematical model, stress concentration, stress-strained state, stress state index
