A wide distribution of valid alternative designs is obtained that establishes optimized tradeoff among all relevant conflicting merit objectives. Therefore, structural engineers have much broader view of the entire optimized design space and thus more flexibility to select, through an explicit tradeoff decision-making process with valuable engineering experiences, the most desirable cost-effective design solution that balances different merit aspects in a preferred manner.
