A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs between a measure of robustness and other objectives to be quantified in a heuristic fashion. Significant insights can then be obtained about how uncertainty in parameter values affects other important design objectives. Results are presented for an application to wastewater treatment plant design.
