Оптимальний вибір параметрів радіоелектронних систем за умовним критерієм максимуму економічної ефективності

Abstract

The method of optimal choice of radio-electronic system parameters according to the measure of maximum efficiency under the predetermined reliability has been considered. Optimization is intended for the estimation of technical and economic expediency of creating of modernizing radio-electronic systems at the stage of real designing system parameters under the known structure and preset signal.The search for optimal functional elements with the required parameters in the broad marketing database or according to the known technical and economic statistics allows increasing economic efficiency of such optimization at the predetermined reliability of the system substantially.The results of the task allow us to determine assured service life and maximum efficiency according to predetermined safety and system cost.The objective function in the task is linearized as in the method of Wolf. This allows transforming the task into separable programming in order to obtain the solution in analytical form. This solution is valuable due to its ability to be used as an iterative formula at any convex nonlinear objective function. It is much easier than Wolf’s solutions and is universal concerning the shape of the objective function and what is more it eliminates the multidimensionality problem and converge quickly.
