Abstract: The productivity of mechanical and hydraulic excavators is the main indicator characterizing the efficiency of their operation and a tool for planning all kinds of works, in which excavators are involved. There is a considerable quantity of techniques to calculate the productivity of mining machines; despite their general similarity and subordination to the same trend, there are many discrepancies which prevent the use of one or another technique as a universal one or creation of such on its basis. Basically, these discrepancies concern the correction coefficients, characterizing the excavator operating modes. When calculating the technical, and even more, the passport capacity, the methods of their calculation are more or less the same, and certain generalizations can be made about the genesis of a particular factor, but the operational performance is a completely different matter. In this paper, the authors analyze the methods of calculating the capacity of excavators according to the manuals of some foreign manufacturers, as well as reference books on mining. Some discrepancies both in the methods themselves and in the mining terminology are established; priority measures for the elimination of the identified shortcomings are proposed.The current situation in the field of software shows the other side of globalization, which, in fact, has led to monopolization of the Russian market by the Western software companies. The solution to this problem is the transition to domestic software. And this is not only the task of the state, but also that of enterprises interested in the stable functioning of their industries and the growth of qualifications of their employees, because domestic developers rely primarily on the knowledge and experience of Russian specialists, involving them in the innovation process.
