摘要
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。
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.
