. "This paper establishes three essential classes of unexpected situations (UX1, UX2, UX3), and concentrates attention on UX3 detection. The concepts of a special Model of System of Situations (MSS) and a Model of a System of Faults (MSF) are introduced. An original method is proposed for detecting unexpected situations indicating a violation of a proper invariant of MSS (MSF). The presented approach offers a promising application for starting and ending phases of complex processes, for knowledge discoveries on data and knowledge bases developed with incomplete experience, and for modeling communication processes with unknown (disguised) communication subjects. The paper also presents a way to utilize ill separable situations for UX3 detection. The paper deals with the conceptual background for detecting UX3, situations, recapitulates recent results in this field and opens the ways for further research." . . . "2"^^ . . . "P(2B06023)" .
