群决策向量方向合成法在项目评价中的应用

The Method of Vector Direction Composition Through Multi-Group Decision-making and It's Application in Project Appraisal

论证了群决策特征根法[1,3]存在的缺陷.考虑到权重决策向量只与方向有关,而与大小无关,提出一种群组决策向量方向合成法,指出用该方法所确定的集结规则H满足公平性,其决策结果满足群组团体影响力的和最大并且是唯一的,较好地解决了该问题.最后,举例予以说明.

This paper demonstrates that there is a bugin the method of multigroup decisionmaking latent root. Regarding that onweighted decisionmaking vector is not relevant to its magnitude but only to it's direction, a new method of vector direction composition through multigroup decisionmaking is put forward. And the collective rules H determinated by the method meet the equity, the result decisionmaked by it ensures that the summation of multigroup influence is maximum and unique. A sample is showed in the end.
