MATHEMATICAL INTERPRETATION OF RISK-MANAGEMENT METHODOLOGY FOR NATURAL-ECONOMIC SYSTEMS

It is in-process well-proven that risk-management naturally-economic systems to the number of which the united territorial communities (OTСs) belong, must take into account their specific. It is predefined that in practice of evaluation of the economic phenomena and processes in naturally-economic systems of the use of traditional methods it is not always possible. The use of tool of fuzzy set theory is for this reason offered. It is shown that the search of optimum mechanisms of adjusting of investment processes at regional level remains an urgent necessity. Above all things it touches territorial societies, as traditional mechanisms of management investment resources, as practice shows, do not provide necessary efficiency. Well-proven expedience for the estimation of the real investment projects which are offered the incorporated territorial societies, to use the mathematical vehicle of fuzzy set theory, when experts can estimate certain part of parameters of project. It is set that in the modern terms of reformation of administrative-territorial device and decentralization of power in Ukraine need the special attention of problem of management a housing-municipal services, as his maintenance is provided by local public authorities and created in the process of reformation the united territorial communities (OTСs). It is suggested to use the theory of fuzzy set theory at the estimation of quality of housing-municipal services. Conclusions. In-process the well-proven expedience of development of new tool of acceptance and estimation of decisions is taking into account the features of process of decentralization of power in Ukraine. It is set that the use of mathematical vehicle of fuzzy set theory is in relation to the estimation of investment projects, will be instrumental in the increase of authenticity of prognosis calculations in relation to economic and social efficiency of the programs and projects of management territories. The well-proven expedience of the use of fuzzy set theory for the estimation of quality of housing-municipal services. It will allow to take into account simultaneously quantitative and high-quality indexes that will be instrumental in the increase of level of efficiency of functioning of housing-municipal services in the united territorial communities.
