The article is devoted to modelling of process of decision-making in difficult systems in the conditions of total uncertainty. The problem is formulated on the basis of synthesis of concepts of the control theory and decision-making, the theory of fuzzy sets and the fuzzy logic, the theory of hierarchical multilevel systems, the utility theory and the theory of games. The given concept expands possibilities of the account uncertainty the various nature, typical to mathematical description of the surrounding validity. Problems of search of decisions in an fuzzy hierarchical control system are designated. The way of the description and finding of alternative decisions in multilevel difficult systems is offered in given article. The algorithm is based on information processing in the form of fuzzy intervals taking into account two kinds the politician conservative and aggressive on the basis of criteria «maxmin» and «minmax». The method of projection on individual interval is used for comparison of the fuzzy intervals presented on various dimension scales. The example showing work of algorithm of a choice of two groups of alternatives is resulted: optimistic and pessimistic on a level of hierarchies of the purposes in the conditions of total uncertainty.

Keywords: Difficult system; decision making, fuzzy interval, the control decision; total uncertainty

This paper proposes criteria for the optimal choice of a database management system (DBMS), based on the requirements to this system. Empirically assessed criteria and method of analytic hierarchy process for decision making were used to carry out the comparative analysis of several DBMSs, implementing relation data model and having similar functionalities. The obtained matrixes of pair-wise comparison are examined for concurrence by calculating indices described in the article. As a result, the database management system for the own project is rationally chosen.

Thermal treatment of Fe-Co-V as an instrument to improve soft-magnetic material devices quality
The process of optimizing the thermal treatment Fe-Co-V alloys used in the magnetic torque motors is studied in order to improve the magnetic properties. It is shown that to achieve high and stable magnetic properties of the alloy it must be annealed in vacuum using inactive coatings. Regime of the annealing process depends on the quality of the original alloy. Quality verification is carried out by measuring the magnetic properties of the control samples . Identifying optimal annealing regime is based on the analysis of a phase diagram of Fe-Co alloy. In connection with that the research of influence of the heating rate , maximum temperature and holding time , cooling rate on the behavior of the magnetic parameters of the control samples is carried out. It was found that the improvement of the magnetic properties is achieved by increasing the exposure time to 6h at the cooling rate of 100 °/hr. As a result a reduction of the coercive force (60 ÷ 50 ) A / m to (28 ÷ 32 ) A / m and increased magnetic induction of technical saturation from (2,0 ÷ 2,10) Т to (2,20 ÷ 2.26 ) T. for Fe-Co-V alloy are achieved. Research of the exposure time and the cooling regime caused a decrease in coercive force of the Fe-Co alloy.
