基于“奖优罚劣”的区间数多指标灰色关联决策模型

With respect to the decision character of multiple attribute decision making with interval numbers, in initializing the attribute data, a new linear changing operator in [-1,1], which is easy to compute and be applied, is proposed. Then the positive ideal point and negative ideal point are defined. A new decision making model was proposed for multiple attribute decision making with interval numbers, which is based on the method of Grey Relational Analysis (GRA). All of the above provide a scientific and applied decision method for multiple attribute decision making with interval numbers. Lastly, this method is demonstrated to be scientific and effective with a practical example.
