MATHEMATICAL MODELLING OF PREFERED SOLUTIONS CHOICE FUNCTION FOR TUBULAR GAS HEATERS BY EXPERIMENTAL INFORMATIONS

The article deals with choice functions building of preferred solutions by experimental information for tubular gas heater working on fuel granules - pellets.Further choice functions using for making technical solutions by tubular gas heaters construction and designing. Recently research analysis. There are works about choice functions construction by separate presents are examined. But full chose functions building by separate presents are not examined. Aims and tasks. There are setting aim to develop full choice functions mathematical model on separate presents by authors. The expert are connect to primary experimental data's evaluation that estimates separate results by output functions (criteria). Its evaluations issue in experimental points paired comparison's table form. Thus, there are necessary construct binary choice relations presents on experimental “points” set by expert that then using for full choice function's constructing. Conclusions. There are choice function's construction's sequence are sets. There are posed point comparison results that characterized tubular gas heater's condition with expert's evaluation using. Also posed output functions comparisons by which can be characterized improving tubular gas heater's performance or vice versa.
