摘要 为了对果实品质进行更全面的评价,从而更合理地选择优良果实品种。该研究以16个果园的"莱阳茌梨"为试材,运用MATLAB软件,确定了距离贴近度和灰色关联贴近度,并基于博弈论思想,计算出贴近度的组合系数,进而求得综合贴近度,构建GC-ITOPSIS果实评价模型。结果表明:样本1的综合贴进度最大,果实品质最佳,即第1个果园的"莱阳茌梨"果实品质最佳。在此基础上,该研究实现了对果实品质的定量预测,建立了果实品质的BP预测模型,预测精度在7%以内。GC-ITOPSIS模型和BP预测模型相结合,不仅实现了果实品质的定量预测,而且提高了果实品质评价的便利性和准确性。 In order to make a more comprehensive evaluation of fruit quality and select better fruit varieties more reasonably.In this study, ‘Laiyangchili’of 16 orchards were used as the test materials, and the distance closeness degree and grey relational closeness degree were determined by MATLAB software.Based on the idea of game theory, the combination coefficient of closeness degree was calculated, and then the comprehensive closeness degree was obtained, and the GC-ITOPSIS fruit evaluation model was constructed.The results showed that the comprehensive pasting progress of sample 1 was the largest,and the fruit quality was the best,the fruit quality of‘Laiyangchili’in the first orchard was the best.On this basis,this study realized the quantitative prediction of fruit quality,established the BP prediction model of fruit quality,and the prediction accuracy was less than 7%.The combination of GC-ITOPSIS model and BP prediction model not only realizes the quantitative prediction of fruit quality,but also improves the convenience and accuracy of fruit quality evaluation.
