中文摘要：

给出区间值相似度集合的概念，并基于区间值相似度集合详细研究了多规则近似推理模型及其推理算法，讨论了基于区间值相似度集合的简单近似推理模型的还原性．最后，通过1个实例验证了推理模型和推理算法的有效性．

英文摘要：

Interval valued similarity measure set of interval valued fuzzy sets was introduced andmathematical model of multiple rules approximate reasoning and its reasoning algorithm were proposed and investigated in detail. One numerical example was used to illustrate the proposed algorithms reasonable.
