In this paper, a new formalism called Engineering Functional Analysis
(EFA) is presented. This formalism results in higher degrees of decent
ralization for engineering system optimization than is otherwise possi
ble. By decentralization, it is meant that the improvement or optimiza
tion of individual components by themselves (i.e., components which ar
e isolated economically from the rest of the overall system) serves to
improve or optimize the system as a whole (within some degree of erro
r, which defines the degree of decentralization). Higher degrees of de
centralization are important in that they provide a more stable econom
ic environment for individual components, thus permitting more rapid s
ynthesis and greater system improvement than could otherwise be obtain
ed.
