Annotation: Boolean algebra is a widely known algebraic method in logic. This algebra is a counterpart of the propositional calculus. To model the predicate calculus, Lindenbaum-Tarski algebra, polyadic Halmos algebra and other algebras were proposed. However, these algebras are too abstract and complicated for algorithmization. In the given paper, we describe our n-tuple algebra that can be thought of as a generalization of mathematical theory of relations.

Annotation: Thi sarticle demonstrates theinfluence of scale on results of complex decisions in methodology Analytic Hierarchy Process (AHP) by Tomas L. Saaty. Investigate questions of transitions to different scales for solving direct and inverse Saaty problems. The results of transitions are demonstrated for solving problem of verify classification.

Annotation: This paper presents an approach of estimation of the control objects and emergency sources based on the integration of OLAP and Expert systems technologies. OLAP-models for multi-dimensional analysis of monitoring data and dynamic analysis of principal parameters of control objects are presented. The criteria of emergency risk estimation using expert knowledge about critical levels of danger are suggested. The implementation of proposed solutions in automated systems that provide a comprehensive safeness of Krasnoyarsk region.

Annotation: This paper proposes an approach for the analysis of data of geo- and hydrophysical monitoring for operational tsunami hazard assessment. Computational methods for estimating the parameters of earthquakes and recovering the form of tsunami source by mareogramms at the nearest DART stations were developed. Parallel version of the computational system for different types of parallel computing systems was implemented.

Annotation: The algorithmic scheme of use of the device of logical decision functions is developed for an assessment of danger of floods.
