 The article deals with a three-objective optimization of slotted filter geometry produced by an innovative method of deforming cutting. This method was developed by Professor N.N. Zoubkov from BMSTU. The multiobjective problem is solved by using the interactive PREF method proposed by the authors. This method is based on the assumption that a decision maker (DM) is able to provide, in some form, preference information related to various solutions proposed by multiobjective optimization software. The DM’s utility function is approximated by a neural network. This work presents a three-objective optimization problem statement of filter design, a short description of an interactive method and its software implementation along with results of computational experiments. 

A direct adaptive method of multicriteria optimization based on neuro-fuzzy approximation of decision maker’s function is considered in this paper. Some results of the investigation of the efficiency of the method for solving two- and three- criteria test problems are presented.

The paper discusses a parameterized three-dimensional model of internal combustion engine mechanical subsystem as an element of computer aided system of engines.  The model consists of some units which makes it possible to build a model of engine with various construction schemes. The problem is solved by using software PRADIS for analysis of dynamic systems.
