Abstract: Aiming at the inconsistency problem of appraising conclusions in comprehensive evaluation of multiple configuration alternatives,a combination evaluation model of equipment demonstration is established in this paper. The model uses Kendall correlation to check up the compatibility consistency of individual method. Then fuzzy-borda number method is used to get the combinational result. Finally,the model uses Spearman correlation to make sure the coherence between the combination evaluation result and those original evaluation methods. A case study shows that the model is feasible and effective. It makes comprehensive evaluation of demonstration alternatives better and more reasonable.
