1. A group decision method on ranking of a large number of alternatives, which is operated in a computer system including an input module for receiving information of multiple alternatives, a database module for storing the information of multiple alternatives, an output module, and a processing module coupled to the input module, the database module and the output module for executing the group decision method by performing a decision computation and outputting a decision result via the output module, the group decision method comprising the steps of:
(A) initializing an iteration index to be one; (B) when the iteration index is equal to one, randomly dividing multiple alternatives into subgroups, and when the iteration index is not equal to one, re-grouping the multiple alternatives into subgroups; (C) ranking each alternative in every subgroup based on information of each alternative to generate a ranking number for each alternative in every subgroup; (D) determining a normalized score for each alternative in every subgroup; (E) when the iteration index i is not equal to a pre-determined number of iterations, incrementing the iteration index and executing step (B), and when the iteration index is equal to the pre-determined number of iterations, executing step (F); and (F) generating an average normalized score for each alternative and sorting all of the alternatives by the average normalized scores of all of the alternatives to generate a final overall ranking result. |
