传统经济数学模型,通常用于分析稳定价格因素,不能解决大幅度农产品价格波动导致农产品价格稳定性降低和价格定位偏差大的问题。数学模型稳定性较低,不能对农产品价格进行准确的预测,采用改进“蛛网模型”获取生产农产品的稳定性条件,实现定位偏差修补,实现农产品价格优化。研究农产品批发价、同类产品价发生波动以及商品的供求矛盾突出情况下,农产品的综合价格波动量,得到农产品价格波动同销售利润间的关系,构建农产品价格波动时动态价格的连续型数学模型,分析农产品最优动态定价问题,实现农产品价格的准确预测。实验结果表明,所提方法可针对大幅度波动农产品价格构建稳定数学模型,具有较高的控制精度。
傳統經濟數學模型,通常用于分析穩定價格因素,不能解決大幅度農產品價格波動導緻農產品價格穩定性降低和價格定位偏差大的問題。數學模型穩定性較低,不能對農產品價格進行準確的預測,採用改進“蛛網模型”穫取生產農產品的穩定性條件,實現定位偏差脩補,實現農產品價格優化。研究農產品批髮價、同類產品價髮生波動以及商品的供求矛盾突齣情況下,農產品的綜閤價格波動量,得到農產品價格波動同銷售利潤間的關繫,構建農產品價格波動時動態價格的連續型數學模型,分析農產品最優動態定價問題,實現農產品價格的準確預測。實驗結果錶明,所提方法可針對大幅度波動農產品價格構建穩定數學模型,具有較高的控製精度。

Traditional economic mathematical model, are normally used for analysis of stability factors of price, doesn't solve the sharp swings in prices for agricultural products, agricultural products price stability is lower and the problem of large price position deviation, the mathematical model of stability is low, can't accurate projections for agricultural commodities prices, with the improved "cobweb model"for the condition of the stability of agricultural production, achieve localization deviation repair, realize the optimization of agricultural prices, the wholesale price of agricultural products, similar products price volatility and the obvious contradiction between supply and demand situation of goods, agricultural comprehensive price fluctuations, get the relationship between the price fluctuation of agricultural products with sales profit, build agricultural prices fluctuate, a mathematical model of continuous dynamic pricing analysis of the optimal dynamic pricing problem of agricultural products, realize agricultural prices accurately forecast. Experimental results indicate that the proposed method can be to large fluctuations in agricultural prices, build stable mathematical model, has higher control precision.
