针对工程机械企业对知识产权产品选择困难的问题，提出一种基于一致性与共识的工程机械知识产权产品推荐群决策方法。在知识产权产品推荐决策过程中考虑了决策专家的一致性与共识水平，结合这两个指标来判断专家是否达到一定的一致性／共识水平。在一致性／共识水平不高的情况下利用反馈机制修正专家偏好。当一致性／共识水平达到一定程度时，采用量词引导优势度与非优势度方法对知识产权产品进行选优。最后，通过一个算例验证了该方法的有效性与实用性。“,”Aiming at the problem that it is difficult for construction machinery enterprises to choose intellectual property products,we propose a group decision making method for construction machinery intellectual proper-ty product recommendation based on consistency and consensus.We consider the consistency and consensus level simultaneously during the recommendation decision-making process and combined to judge whether the consistency/consensus level of experts reach a certain level.Using the feedback mechanism to change the preferences of experts when the consistency/consensus level is not high.When the consistency/consensus lev-el reaches a certain level,we use the quantifier guided dominance degree (QGDD)and quantifier guided non-dominance degree (QGNDD)to select the suitable intellectual property product.Finally,we use an ex-ample to verify the validity and practicability of the method.
