WebSep 1, 2009 · Reference points consist of aspiration levels reflecting desirable values for the objective functions. This is a natural way of expressing preference information and lets the DM express hopes about his/her most preferred solutions. In multi-objective optimization, the Pareto front (also called Pareto frontier or Pareto curve) is the set of all Pareto efficient solutions. The concept is widely used in engineering. It allows the designer to restrict attention to the set of efficient choices, and to make tradeoffs within this set, rather than considering the full range of every parameter. monarch french
