Abstract: The concept of combination evaluation is an important content in the comprehensive evaluation theory and methodology. In this paper firstly defines the term of recombination evaluation is firstly defined and a recombination evaluation approach is proposed based on the previous evaluation results, which mainly deal with the nonuniformity and poor convergence of the first evaluation results derived from different combination evaluation methods, such as fuzzy borda method, copeland method and maximizing deviation decision method. Then, some key processes and operation steps to conduct this approach are detailedly given, which includes description of comprehensive evaluation problem, description of single evaluation method, description of combination evaluation, consistency analysis of different evaluation results, selection of recombination evaluation method based on minimum drift and convergence analysis of the results of recombination evaluation. Finally, from the numerical examples, it can be seen that the result error of the recombination evaluation is far less than result from any single first combination evaluation. Therefore, the conclusion that the recombination evaluation has better combination results and is more effective can be drawn. The recombination evaluation approach can effectively improve uniformity and convergence of of the first evaluation results derived from different combination evaluation methods, and decrease error of the first combination evaluation results. Ultimately, the reliability of the overall evaluation results can be strengthened. The contribution of this paper includes: 1) firstly proposes and defines the term of recombination evaluation; 2) presents a selection rule of recombination evaluation method based on minimum drift and convergence analysis of the results of recombination evaluation; 3) constructs a methodology architecture to carry out this recombination evaluation approach.
