For the bilevel decision problem with multiobjective, this paper discusses its decision mechanism from the decision makers preference relationship: semi-cooperation and pure independence, we show that their noninferior solution sets can be represented by using the augmented weighted Tchebycheff norm problems.
针对一类多目标两层决策问题，从上、下两层决策者之间的偏好关系出发，探讨了问题的决策机制：半合作决策机制与纯独立决策机制，说明了可以利用增广加权Ｔｃｈｅｂｙｃｈｅｆ范数问题来有效地表示它们的非劣解集，据此设计辅助这类多目标两层决策问题的交互式决策方
