Abstract In this paper, we consider the problem of constructing the functional structure of the expert system designed for the decision of problems of business management. We provide a generalized approach to the problem of the establishment of mechanisms and tools based on information technology to support the process of managerial decision-making and the formation on this basis of the functional structure of the expert system. We propos to expand the structure of expert system in order to achieve the availability of user-defined functions through the implementation of additional functionality in the form of modules of knowledge engineering, data bank, training and advising (analysis and interpretation of accepted administrative decisions) blocks. The proposed approach allows to develop tools to support decision making in management on the basis of fuzzy logic methods that ensure the effectiveness of decisions taken and enhancing the stability of functioning of small and medium enterprises in conditions of uncertainty. Area of knowledge, which serves the use of expert systems based on fuzzy logic, is the management of the enterprises of small and middle-sized business. The use of models and methods of solving problems with the use of fuzzy logic is predetermined by objective realities of the existence of the enterprises in conditions of uncertainty, fuzziness of initial data and the complex spatiotemporal situation.
