The analysis of numerical methods in combustion theory considered in this paper allows us to find the optimal solution of systems of differential equations of kinetics of complex chemical reactions and provides an opportunity to obtain information on: - options for solving mechanisms at known values of velocity constants for various stages of a complex reaction; - on the concentration values of all components as a function of time throughout the reaction for each of the considered mechanism. Therefore, a comparison of calculated and experimental concentration values is possible for any component and any time intervals available for the experiment. The degree of sensitivity of the mechanism to changes in the rate constants of individual reaction stages and their various groups, as well as the degree of sensitivity to variations in reaction conditions (temperature, pressure, initial composition, etc.) of the mathematical model corresponding to the mechanism under consideration. It is essential that such a study can be conducted without any additional experimental data.
