    «Possibilistic mathematical programming tasks stability»
    Problems of sensitivity to perturbations in possibilistic programming problems were considered. For the solution set mapping and for the optimal value function, stability results are derived in general case [Yazenin, 1987, 1996]. Example shows the necessity of the formulated conditions and illustrates sharpness of the results in the respective settings.

    «On solution method for the maximization of fuzzy goal achievement possibility task in case of mutually Tw-related parameters»
    Task of maximization of fuzzy goal achievement possibility in case of mutually Tw-related parametes is investigated. Indirect solution method based on construction of equivalent deterministic analogue is proposed.

    «Multicriterial analysis of fuzzy objects with experts' fuzzy estimations clustering»
    The article represents a multicriterial alternatives' ranging method involving a set of the experts' fuzzy estimations. The experts' fuzzy estimations clustering method based upon the fuzzy criteria weights is also given in the article.

    «Oil wells interaction analysis based on hybrid clustering of wells productivity time series»
    In the article hybrid clustering is used in order to analyze interaction between different oil wells. Hybrid clustering helps to solve two problems: detect oil wells that belong to the same collector and detect wells that probably belong to different collectors but are interconnected by means of ground water.
