顾客搜索强度影响下短生命周期产品订货决策

Ordering Strategy of Short Life-Cycle Products Under the Influence of the Customers Search Intensity

根据短生命周期产品的特点,考虑与需求相关的顾客搜索强度,在假设溢出需求为顾客搜索强度函数的情况下,建立了考虑顾客搜索强度因素的斜坡型需求模型,分两种情形对模型最优解进行了存在性证明和求解.然后通过数值算例分析了主要参数变化对缺货时间、订货量、库存成本的影响,发现订货量与顾客搜索强度同方向变动,缺货时间与需求变化临界点出现先后的不同,缺货成本、持有成本和变质成本对库存总成本的影响不同.

According to the characteristics of the short life-＇cycle products, and considering the customer search intensity, the ramp-type demanding model is established. The model is based on the assumption that the overflowing demand is a function of customer search intensity.Two cases for the optimal solution to the model have been proved the existence and solution.Then a numerical example is provided to illustrate the the influence of the main parameters on the shortage of time, order quantity and inventory cost.It can be found that the quantity of products changes in same direction with the customers search intensity, Besides, as the difference between the shortage of time and the demand changing point appearing successively, the shortage cost, holding cost and deterioration cost have different influence on the total cost of the inventory.
