The paper considers a new approach to group classification of objects, which are described with many qualitative attributes and may exist in several versions. New options of the multi-attribute objects’ aggregation and features of the classes generated are discussed. Clustering and sorting techniques are based on the theory of multiset metric spaces.

Keywords: group classification, clustering, sorting, multi-attribute objects, multiset metric space

The paper considers approach to hydroacoustic field on the basis of intelligent geoinformation system (IGIS). The composition and structure of such special IGIS are proved. We give the example practical realization of system of hydroacoustic calculations (SHC) on the basis of IGIS possessing the expanded possibilities in comparison with known decisions.

An approach to a sensitivity analysis of the set of non-dominated objects is proposed. It is shown that the sensitivity analysis of the choice under multiple criteria made on the base of the criteria importance theory may be effectively executed with the help of linear programming techniques.

Keywords: sensitivity analysis, partial preference relation, non-dominated variants, multi-criteria problems, coefficients of importance, weights of criteria.

Approximate heuristic for multicriteria multiple choice knapsack problem is suggested. Results of computing experiments for comparison of the suggested algorithm and exact enumerative algorithm are examined. Influence of parameters (number of elements, number of element groups) to algorithm efficiency is considered. Importance of resource constraints to algorithm efficiency and results is considered as well. Computational results are based on various initial data sets. Recommendations for the use of the suggested approximate algorithm in real problems are presented.

Keywords: combinatorial optimization, multicriteria multiple choice knapsack problem, heuristics, enumerative algorithms, dynamic programming, computing experiment

Basic steps of solving a problem in electrodynamics may be represented as following: to formulate the problem with formalized fundamental terms (to construct up a physical model); to formulate the problem mathematically (to construct up a mathematical model); to formulate the problem with differential and integral equations; to define value boundary conditions for differential equations; to evaluate parameters of mathematical model and selection criteria for optimal solution; to solve electrodynamics problem with the assistance of analytical and numerical methods (possibly with mathematical software packets); to select analogues; verification of the solution; analysis of the solution. Thus the construction of a computer system to support the selection of models, methods and algorithms for solving mathematical physics problems, incl. electromagnetic, is of paramount importance.

Keywords: computer system, electrodynamics problem, selection control, decision making.
