Considering Dynamic s-Pareto Frontiers in Decision Making

摘要

Considering how the resolution of conflicts changes over time is an aspect of mul-tiobjective optimization that is not commonly explored. These considerations embody changes in both the preferences that dictate the selection of Pareto designs, and changes in the Pareto frontier itself over time, or s-Pareto frontier when a set of disparate design concepts are considered. As such, this paper explores the idea of dynamic s-Pareto frontiers and preferences. Specifically, this paper presents a dynamic multiobjective optimization problem formulation that provides a framework of identifying the s-Pareto frontier for a series of time steps. The application of the presented dynamic formulation is illustrated through a simple aircraft design example.
