Abstract
Approximation, Adaptation and Automation (AAA) concepts have been developed in this paper for sizing large-scale structures modeled using finite elements. Four main constituents of AAA concepts have been suggested and described in this paper which can be potentially very effective in reducing the number of analysis cycles. They are based on several innovative principles and considerations which increase efficiency and/or promote independency of the design iteration cycles with respect to one or more of the following: (i) number of design variables; (ii) number of active constraints; (iii) forms of design variable linkings; (iv) types of constraints; (v) types of finite elements used in modeling; and (vi) size and types of structures involved.
