The goal of the article lies in approbation of the hierarchical model of assessment of the level of innovation development of an industrial enterprise on the basis of instruments of fuzzy logic on the basis of the engineering enterprise Zavod Krasilovmash LLC. By means of analysis of the works of domestic and foreign scientists the article considers main modern approaches to the quantitative assessment of the level of innovation development and its components. In the result of the study the article builds a hierarchical model of assessment of the level of innovation development of the Zavod Krasilovmash LLC with the use of the Fuzzy Logic Toolbox component and GUIDE environment of the Matlab 8.0 environment. The conducted study shows that the model of assessment of innovation development of an enterprise and its components could be used for further adjustment of the process of managerial decision making with respect to formation of the enterprise strategy. The prospect of further studies in this direction is development of managerial recommendations on elimination of bottlenecks of innovation development detected in the result of use of the developed model.
