A mathematical model of the octane number and a method of identification of the octane numbers of the components being mixed using a laser optico-acoustical octane meter are given. For this purpose the inverse problem of petroleum mixture analysis using a genetic algorithm is solved.</p>Laser optico-acoustical octane meteroptimizationcompound-fillingcommercial petroleumidentificationmathematical modelspectral channels of measurementcalibrationЛазерный оптико-акустический октаномероптимизациякомпаундированиетоварный бензинидентификацияматематическая модельспектральные каналы измерениякалибровка
