非立即损耗和存货影响销售下的高科技农产品订货策略

摘要

Scientific and technological innovation is an important approach to achieve modernization of agriculture.Making great efforts to develop high technology produce has a significance for increasing the yield,and improving the quality and safety of products and promoting sustainable development of agriculture.Considering that high technology products have an obvious phenomenon of stock-dependent selling rate and non-instantaneous deterioration,an ordering model of high technology produce with two-level stock-dependent selling rate and non-instantaneous deterioration is established.Numerical simulation is calculated by mathematica 5.0 software and the effect of key parameters such as stock-dependent selling rate,product deterioration rate and quality guarantee period on ordering policy and average profit are analyzed.It shows that the factor of stock-dependent selling rate and the deterioration rate have a greater impact on the ordering policy than that of other factors ; the factor of stock-dependent selling rate and the critical point of stock-dependent selling rate have a greater effect on the average profit than that of others.The two factors should be considered to make order policy for distributors.%科技创新是实现农业现代化的一个重要手段,大力开发高科技农产品,对增加农产品产量,提高其品质和安全水平,以及促进农业长期可持续发展具有十分重要的意义.考虑高科技农产品存在明显的存货影响销售和非立即损耗现象,建立一个两阶段存货影响销售的非立即损耗产品订货模型.利用Mathematica5.0软件进行数值仿真计算,分析存货影响销售、产品损耗和产品保质期对订货策略和平均利润的影响.研究结果表明:存货影响销售率因子和产品损耗率对订货策略影响较大,而存货影响销售率因子和存货影响销售临界点对平均利润影响较大,在制定订货策略时必须考虑这两大因素.
