Abstract:
We consider Multi Criteria Decision Making (MCDM) as the conjunction of three components: search, preference tradeoffs, and interactive visualization. The first MCDM component is the search process over the space of possible solutions to identify the non-dominated solutions that compose the Pareto set. The development of efficient search algorithms has been the goal of Multi-Objective Optimization (MOO), from classical mathematical programming to evolutionary approaches. However MOO's emphasis has been on generating densely sampled, well-distributed Pareto sets, without worrying about the solution selection phase. The second component is the preference tradeoff process to select a single solution (or a small subset of solutions) from the Pareto set. The development of methods to capture and aggregate preferences has been the goal of Bayesian and Fuzzy decision-making techniques. However, their emphasis has been on the aggregation mechanisms to select a solution, rather than the solution generation phase. The third component is the interactive visualization process to embed the decision-maker in the solution refinement and selection loop. We often need to embed the decision-maker in the solution refinement and selection loop. To this end, we need to understand and present the impacts that intermediate tradeoffs in one sub-space could have in the other ones, while allowing him/her to retract or modify any intermediate decision steps to strike appropriate tradeoff balances. We focus on the intersection of these three components and we highlight some research challenges, representing gaps in the intersection. We introduce a requirement framework to compare most MCDM problems, their solutions, and analyze their performances. We focus on two research challenges and illustrate them with two case studies in electric power management and financial portfolio rebalancing.
