摘　　要：基于凸组合和可能度,给出了一种从区间数互补判断矩阵得到区间数优先权重的方法。其中包括检验由区间数互补判断矩阵构造的一族实模糊互补判断矩阵的弱传递性与不一致性以及修正它们的不一致性使之具有弱传递性。通过算例说明此方法的可行性和有效性。Based on convex combination and possibility degree, an approach is proposed to generate interval number priority weights from an interval number complementary judgment matrix. The inconsistency and weak transitivity of a family of real complementary judgment matrices generated by interval number complementary judgment matrix are identified and their inconsistency is repaired to reach weak transitivity. Finally, a numerical example is calculated to demonstrate its feasibility and practicality.

关 键 词：区间数互补判断矩阵 可能度 凸组合 一致性
