基于升值期和贬值期时间变化的补货策略与定价决策

本文考虑时间对价格和需求量的影响,对产品在供应链环境下,分别以升值期和贬值期为时间周期作了供需关系及其补货与定价决策的定量研究。通过分别建立供需双方的利润函数模型并导出供方的最优定价和需方的最优订货量。在升值期中,供需双方在各补货周期内的利润随时间推移而增加,且产品价格和需求量也呈上升趋势;而在贬值期中,供需双方在各补货周期内的利润随时间推移而减少,且产品价格和需求量也呈下降趋势。最后,通过实例证实了上述结果。

Ordering Policy and Its Price Decision-making Based on the Change of Appreciation and Devaluation Time

This paper considers the influence which time on the price and the demand quantity, as to products in the supply chain, take the appreciate time and the devalue time as one time cycle. We do the quantitative investigation on the relations between supply and demand, and its making up the goods and the price decision - making. We could derive the supplier's optimum price and the consumer's optimum ordering quantity through separately establishing the profit function models of both sides of the supply and demand. In the appreciate time, the profits of both sides of supply and demand are increased by the time going in each period, the product price and the demand quantity also assume the trend of escalation. But in the devalue time, the situation is just opposite. Finally, we explain the results through the computation example. The paper in the research on the inventory management of products in the appreciate time and the devalue time has the very strong reality and significance.
