在我国国民经济中,发展现代农业必须依靠高端科学技术。大力开发高科技农产品,对增强农业综合生产能力,增加农产品产出量,提高农业经济效益有着十分重要的意义。考虑高科技农产品市场需求受产品新鲜度、价格和库存水平的影响,建立了一个新鲜度、价格和库存水平影响需求的高科技农产品订货模型。利用mathematica8.0版仿真软件进行数值计算,分析了价格和时间敏感因子、库存水平影响需求因子、销售价以及新鲜度衰减因子等对高科技农产品订货策略和平均利润的影响。研究结果表明：当价格和时间敏感因子、库存水平影响需求因子和初始新鲜度增大时,销售商应延长产品有现货时间,缩短缺货时间；当新鲜度衰减因子和新鲜度临界点增大时,应缩短有现货时间,延长缺货时间；当需求价格敏感因子增大时,销售商应延长有现货和缺货时间。

It must be rely on high-end science and technology to develop modern agriculture in our national economy. It has very important practical significance on strengthening comprehensive agricultural production capacity, increasing agricultural output and improving agricultural economic benefits through developing high-tech produce vigorously. Considering the market demand of high-tech produce is affected by freshness, price and inventory level, an ordering model of high-tech produce which the demand is affected by freshness, price and inventory level is generated. The effect of key parameters, such as price and time sensitive factor, inventory level dependent demand factor, freshness attenuation factor and the selling price on order policy and average profit of distributors is analyzed by numerical simulation through mathematica8.0 software. It shows that the in stock time should be extended and the stockout time should be shortened when the price and time sensitive factor, inventory level dependent demand factor and the initial freshness increases. The in stock time should be shortened and the stockout time should be extended when the freshness attenuation factor and the critical point increases.The in stock and stockout time should be extended when the demand price sensitive factor increases.
