To assess the achievement of goals in the context of implementing a sustainable development model, we are considering the methodical and applied tools based on the use of the theory of fuzzy sets and the technology of implementing the model of communication between its individual indicators, which should be used in developing scenarios of strategic development of Ukraine

A dynamic system that consists of two subsystems is considered. The influence of defuzzification method on quality indicators of the system is investigated. A comparison of the main defuzzification methods is held

In practice, information on statistical characteristics of series mode interference is available only in certain cases. Moreover, for this or that reason input variables are measured inexactly, and their values can be specified with some uncertainty. The identification task is significantly complicated when the measuring signal passes through a natural channel with unknown statistical characteristics. This is, for instance, the case with well drilling when axial weight on the drilling bit and drilling bit rotations per minute are gauged by above-ground devices.
