Fuzzy evaluation of IP network running quality using WOWA

For comprehensive evaluating network running status the network running quality metrics were designed to reflect the network quality. The grade of membership vectors were used to compute metrics´ statistic value which can definitely reflect the metrics´ ranks in the period of statistics. The fuzzy comprehensive evaluation method based on the Weighted Ordered Weighted Averaging operator (WOWA) was presented for evaluating the network running quality. The method considered the importance of the metrics and decision-maker´s preference. The case study shows that the method can not only get the right evaluation results, but also be more flexible in comparison with the normal fuzzy evaluation method.
