Sovereign Credit Risk Assessment with Multiple Criteria Using an Outranking Method
Algorithm 1
Routine for PROMETHEE II.
Step 1. Determine the deviations based on pairwise comparisons. | | Where denotes the difference between the consequences of the alternatives and for each criterion j. | Step 2. Apply the preference function. | | Where denotes the preference of alternative of over the alternative , for each criterion j, based on the deviation | . | Step 3. Calculate the outranking degree. | | When the outranking degree of the alternative over the alternative is the weighted sum of the set of preference functions of | the form because of the weights of the criteria, represented by . | Step 4. Calculate the positive and negative flows regarding the partial ranking of PROMETHEE I | | | Where e denote, respectively, the negative and positive flows of alternative . | Step 5. Calculate the net flow with regard to the complete order of PROMETHEE II | | Where denotes the net flow with regard to alternative |
