Abstract:Based on the market prices of 28 kinds of agricultural products in cities,the price level of agricultural products was comprehensively evaluated by means of grey evaluation based on the triangle withenization weight function.The cities were ranked by comparison of market prices of agricultural products.The accuracy of grey evaluation is improved because of the improvement of mean generation and the selection of evaluation indexes.
Keywords:compound mean generation  synthetic ratio price triangle whitenization function  synthetic clustering coefficient
