Input: suspected congestion link set and decision matrix Output: sorted set of suspected congested links 1. Standardize the decision matrix according to formula (12) to obtain a standardized decision matrix . 2. Based on formula (13), the weight of the index is substituted into to obtain a weighted standardized decision matrix . 3. Use formula (14) to calculate attribute ideal point , and use formula (15) to calculate attribute negative ideal point . 4. For each suspected congested link in the set of suspected congested links, use formula (18) to calculate its distance to the ideal point , and use formula (19) to calculate its distance to the negative ideal point . 5. Use formula (20) to calculate the congestion probability value of each suspected congestion link . 6. Based on the value of the link, sort all the suspected congested links in descending order to obtain the set .
