Application of conjugate-gradient method for industrial enterprise efficient management

The present paper considers the industrial enterprise efficient management procedure that includes econometric (in Excel) and graphical (in Maple) plotting of the target function as well as searching of this function minimum though the application of conjugate-gradient method. The stepwise minimization of the function of losses in two-factor space of controlled variables was performed in Excel. The confidence of nonlinear target function and optimal solution error were estimated.
