Abstract
The methods of standard deviations,maximizing deviations,entropy weight and their improved methods were applied to solve the objective weight determination problem of multivariate indexes in performance evaluation.It made the weight determination selection more comprehensive.The conflict of the indexes was introduced to take account of the correlation between indexes.The case study was implemented in VOIP network.The samples used to compute weights were obtained by simulation.Six weight computing methods were compared for selecting more objective weight determination method.The results show that Criteria Importance Through Intercriteria Correlation(CRITIC) method can get better objective weights.
