Application of the combined tactic of AHP and gray relation analysis in the evaluation of ornamental pepper fruit appearance quality
[Objective] T he purpose of present study was to evaluate the combined technology of A HP and gray relation analysis in the appearance quality determination of ornamental pepper fruits .[M ethods] Twelve different ornamental pepper fruits were selected as the research material .T he appearance quality of the ornamental pepper fruit was synthet‐ically analyzed by the method of analytic hierarchy process and gray relation analysis .T he ornamental pepper fruit ap‐pearance quality evaluation system was built up ,which included 3 levels (target layer ,constraint layer ,and index lay‐er) and 13 indexes (fruit shape ,fruit transverse diameter ,fruit profile ,fruit shape index ,fruit shoulder diameter , fruit maturity color ,fruit discoloration color ,single fruit weight ,flesh thick ,number of ventricles ,fruit birth mode , fruit table and length of fruit stalk ).[Results] T he results showed that five species ,including Q6 ,W1 ,Q1 ,Q4 and W4 were superior in appearance quality ,and the other four materials ,including B3 ,Q5 ,S1 and Q2 were good in ap‐pearance quality ,and the three materials ,named W6 ,B7 and Q3 ,were poor in appearance quality .[Conclusion] T he combination of analytic hierarchy process and gray relational analysis can be used to evaluate the appearance quality of ornamental pepper fruit conveniently ,effectively and quickly .
