摘要
Methods and systems are described for integrating Multi-Objective Optimization (MOO) with a Constraint Management System (CMS) so as to rapidly and flexibly search large design spaces and focus on “interesting” designs as determined by user-specified criteria. An exemplary method embeds the value of a trade space and its trade-off envelope within the same CMS network used to calculate the values of the points in the trade space itself. The exemplary method supports automatic variation of the resulting trade-off analyses in response to variations in upstream parameters, assumptions, and/or requirements not explicitly used in the optimization problem but which nevertheless impact the results. When mathematically feasible, the CMS can back-solve for values of one or more of the upstream parameters so that one or more selected attributes of the trade-off envelope achieve user-specified values. The coupled use of a CMS with multi-objective optimization avoids the extremely laborious procedure of generating a very large set of permutations of inputs and factors and then restricting the analysis to those that have desired outputs or of having the user manually “reformulate” the equation set so that it solves in the desired direction.
