Lazorenko V. Modeling the assessment of financial sustainability of the service sector enterprise

The dissertation is devoted to theoretical substantiation and development of methodical approaches and practical recommendations for modeling the estimation of financial stability of the enterprise sphere of services. In the dissertation the complex research of the problem of financial stability assessment was conducted and new methodical approaches to the decision of the financial sustainability evaluation of the service sector were implemented. The essence of the concept of "financial stability" is investigated and the concept of "financial stability of the enterprise sphere of services" is systematized. The formalization of the seasonality estimation with the help of a linguistic variable-tuple, which is a generalization of the fuzzy set, is proposed. The regional distribution coefficient is proposed to be considered as a random variable distributed according to the normal law, where the center of the location defines the mathematical expectation, and the mean square deviation characterizes the distance from the object to the center of the location. The economic-mathematical model of the financial stability assessment process is developed by calculating the integral index of financial stability of the service sector enterprise.
