Large System Optimization Using Decomposition With Soft Specifications

Abstract

<p>The problem considered is that of obtaining an optimum solution to large nonlinear engineering system by coordinated optimum solutions of smaller sub-systems. The technique produces a way of displaying graphically and numerically the trade-offs between each sub-system design objective and the sub-system joint design specifications. A nonlinear multi-variable fitting model is developed to represent the trade-off hypersurface. Shape, potential and advantages of the trade-off surfaces also are illustrated.</p>
