摘　　要：研究了权重已知、各指标值是区间数的多指标决策问题.以投影原理作为依据,通过确定区间型理想点,考虑各方案在理想点上的投影来对所有方案进行排序,最后用该决策方法分析了一个实际问题,并取得了满意的结果.In this paper, the multi-attribute decision-making problem with known weight and the attribute values of interval numbers was discussed. First, the interval ideal point was defined, and based on the projected method, the most desirable alternative was found by confirming the projection on the interval ideal point. Finally, an example was given and the result obtained was satisfactory.

关 键 词：多指标决策 理想点 投影 区间数 权重
