Abstract:  Nowadays, fuzziness is still a problem for many existing multiindex evaluation methods, which brings some negative effects to the evaluation results. However Intermediation Theory is good at dealing with fuzziness. Combined with Analytic Hierarchy Process (AHP), a multiindex evaluation method based on Intermediation Theory is proposed. An application of this method in evaluating software process performance is given, in which Weighted Average Method, TOPSIS and Entropy Weight Method are compared with this method. The application results show that Mediation Weighting Method can be well applied to software process evaluation.

Key words: intermediation theory, multi-index, the medium weighting method
