A Visualization Framework of Pareto Optimization for Decision Making

Achieving the best tradeoffs is difficult when multicriteria involved. Pareto optimal is a common way to balance the multi-objective tradeoffs. However, when the number of criteria increases, it is difficult for users to make the decision since the balance is not that clear or intuitive. We propose a framework to visualize the Pareto optimization such that the tradeoffs are clearly seen and easily turned into decision. Since the number of criteria is large, we first divide the criteria into 2-pair groups. This could assist users to make better comparison. To obtain more broader view and make more correct decision, we divide the criteria into 3-pair groups and then visualize them with a 3D surface. Finally, with the case studies, it turns out our framework is useful for the multi-criteria decision making.
