基于确定初始库存的改良品开售时机决策研究

Selling Opportunity Decision Strategy for Ameliorating Items with Definite Initial Inventory

改良品的开售时间影响售罄时间,并决定其单位时间利润.本文以改良品的开售时间为研究对象,考虑改良率、变质率、顾客需求率等因素,分别建立产品在最佳口感期结束时刻、结束之前、结束之后售罄的改良品最佳售卖时机决策模型.求解最佳开售时间和最大单位时间利润.通过具体算例,比较初始库存量一定时,各模型的最优解,为改良品开售时间的选择提供参考依据.对改良率和初始库存量进行敏感性分析,研究它们对单位时间利润的影响.

Selling opportunity of ameliorating items affects the selling out time and profit per unit time.The research object is the selling opportunity.It establishes 3 models.They are of the products sold out on,before and after the end of the best taste period,withconsidering the amelioration rate,deterioration rate,customer demand rate and other factors.By solving nonlinear equations and nonlinear programming problems to get the optimal selling time and the maximum average profit.The model is numerically illustrated with comparing the optimal solutions of the 3 models when the initial inventory is fixed.It provides a reference for the selling opportunity decision.The sensitivity analysis of profit per unit time with respect to amelioration rate and initial inventory is presented.It shows that improving amelioration rate can effect ively increase the profit per unit time.
