Knowledge oriented technologies utilize historical activities as cases for later decision-making such as Case-based Reasoning. This article proposes an available method of CBR referring to historical multi-person decision making processes for rigid reasoning to overcome the defect of traditional MCGDM in which the process of linguistic evaluation data and collective consistency analysis are performed. And the example given shows its availability.
