Description: The problems of modeling economic safety of machine-building enterprises in the face of uncertainty. An improved model of estimation of economic security, as well as its form of interval for the case where some of the functional criteria are vague. The description of the interaction of information technology information flows, processes and tools for modeling and diagnostics of economic safety engineering enterprise in the face of uncertainty. The proposed models, methods and algorithms are tested on the basis of data on the activities of SJSHC "Artem".
Keywords: functional criteria, adaptive sampling, interval number, information flows, stimulating factors
