Abstract

Focus on the evaluation index system for customer orders are too complicated and the evolution weights are too subjective, this paper presents a method. On the basis of the original data, the indexes are reduced based on the rough set theory according to the importance of the indexes, objective weights of reduced the indexes are, the priority sequence of multiorders is assessed by constructing an object close to the ideal point of degree programs on a number of priority assessments. A case study shows that this method is effective to assessment orders.
