Selection of Design Solutions at the Optimization Stage under Conditions of Uncertainty on the Basis of a Functional-Parametric Approach
The paper considers the problem of circuit design of analog technical devices and systems taking into account random processes of changing their parameters and requirements of reliability. The difficulties that arise when using a functional-parametric approach with a problem area in the form of optimal parametric synthesis in conditions of a shortage of initial information are analyzed. The possibility of reducing the computational complexity through the use of preliminary analysis of the source data, parallel and distributed computing technology is evaluated. The evolutionary synthesis algorithm under the existing conditions is described, some ways to overcome the difficulties that arise at the optimization stage are proposed. The possibility of using evolutionary computations with the probabilistic nature of the optimality criterion, the nonlinearity of the objective function and the restrictions on it is estimated.
