摘　　要：在定义三参数区间数的基础上,给出了三参数区间数的运算关系;然后将权重为区间数的多指标决策问题转化为指标取值为三参数区间数的多指标决策问题;在三参数区间数理想方案点定义的基础上,给出了权重为三参数区间数的逼近理想点法;最后将其应用于某城市公交线网的优化调整中。结果表明,该法科学合理、切实可行。This paper studied interval numbers of three parameters by using system knowledge. Based on interval numbers of three parameters, it gave the definition of ideal plan of multiple attribute decision-making problem with interval numbers of three parameters, by which it gave TPOSIS to multiple attribute decision-making problem with interval valued weight. Thus it provides another reasonable and effective method for the multiple attribute decision problems.

关 键 词：多指标决策 三参数区间数 逼近理想点法
