基于优势关系的粗糙集应用研究

Research of the Application of Rough Set Based on Dominance Relations

目前,在价值工程系数评价方面所具有的确定方式已经有较多种,并能够较好地应用到实践当中。对于这部分方式来说,其都能够对决策者的属性判断进行良好的反映。通过价值工程中粗糙集理论的引入,则能够根据其属性重要性对对相关功能属性的权重情况进行确定,同传统方式相比,其不仅能够对权重确定的主观性进行克服,也能够获得更为客观的处理效果。在本文中,将就基于优势关系的粗糙集应用进行一定的研究。

At present, there are many kinds of confirmation prescription in factor evaluation of value engineering, and all of them can be well applied to the practice. This part of methods can well reflect the property judgement of decision makers. The introduction of rough set theory of value engineering can determine the weights of attributes of the related functions according to the importance of attributes.Compared with the traditional way, it can overcome the subjectivity of determining weights and get more objective treatment effect. This paper stuides the application of the rough set based on dominance relations.
