MATHEMATICAL MODEL FOR DECISION MAKING SYSTEM BASED ON THREE-SEGMENTED LINEAR REGRESSION

Context. The problem of approximation empirical data in the decision-making system safety management.. object study was to verify adequate coefficients mathematical model for using information technology.
 Objective. goal work is creation math-ematical technology on bases analyze different approaches approximating an that can be used predict current state operator flight system..
 Method. A comparative analysis description transformation indicators with a non-standard structure. following models similar visual representation are selected comparison: parabolas second and third order, single regression jumps. It proposed use new approximation, based criterion by Kuzmin Heaviside function. adequacy checked these criteria, which allowed choose describe indicators. stages obtaining were as follows: determining minimum sum squares deviations all simultaneously; function; optimization abscissa axis certain areas; linearity test. obtained adequately describes process indicators, will allow forecasting changes medical biological operators performance professional duties aviation, one methods human factor proactive approach safety.
 Results. results during construction this kind.
 Conclusions. Experimental studies have suggested recommending three-segment linear jumps formalize structure practice build predicting dysfunction causes adverse events aviation.
 Prospects further research may multiparameter violation functional informative parameters, well experimental wide range practical problems nature dimension.
