分析了谷物干燥性能指标，并将其分类。运用层次分析法结合专家调查把复杂问题简化，求出了各指标的权重。在层次分析法的基础上采用德尔斐法计算出指标重要程度系数，并进行了比较分析。为计算谷物干燥性能指标的综合效用提供了一种新方法。
Analyzed the grain dryness performance index and classify it. By using AHP and expert investigation, the complex problems are simplified and the weight of each index is calculated. Based on the analytic hierarchy process, the Delphi method was used to calculate the coefficient of importance of indicators, and a comparative analysis was made. It provides a new method for calculating the comprehensive utility of grain dryness index.
