The monograph is devoted to the problem of objective assessment of the company competitiveness for strategic decisions choice. Various approaches to its measurement, not always expedient in concrete business conditions, are offered in theory and practice. Key features of the telecommunication companies’ activity, influencing its competitiveness, are systematized in the research. Analytical tools of its assessment, including the matrix analysis and method of the analysis of hierarchies, are proved, adapted and applied. The existing and potential competitive positions of PJSC MegaFon are specified. Viable investments are proved, taking into account a condition of various segments of the company business. The recommendations about improvement of an assessment technique and mobilization technique of competitive advantages of the telecommunication companies are offered.

According to the researcher one of the aims of geometrodynamics is to eliminate the concept of mass as a fundamental property. The author presents a promising approach to achieving this end. In order to do this, the researcher considers the interface between different solutions of the Einstein field equations, and constructs an extension of these equations and their solutions. This forms the basis of a metric-dynamic model of particles of varying sizes, including virtually all elementary particles that are part of the Standard Model.

The monograph states that one of the stages of machine-hardware complex development at the enterprise as a set of technical objects is the design of process scheme, selection and justification of the applied equipment. One of criteria of efficiency of the project is the total cost of equipment and operations including, as a special factor, the associated costs for its creation. Associated costs are calculated as a percentage of the cost of the new equipment, calculated on the basis of the empirical power function model with adequate for further use accuracy.
