Selling to strategic and loss‐averse consumers: Stocking,procurement, and product design policies 下载免费PDF全文
Motivated by the presence of loss‐averse decision making behavior in practice, this article considers a supply chain consisting of a firm and strategic consumers who possess an S‐shaped loss‐averse utility function. In the model, consumers decide the purchase timing and the firm chooses the inventory level. We find that the loss‐averse consumers' strategic purchasing behavior is determined by their perceived gain and loss from strategic purchase delay, and the given rationing risk. Thus, the firm that is cognizant of this property tailors its inventory stocking policy based on the consumers' loss‐averse behavior such as their perceived values of gain and loss, and their sensitivity to them. We also demonstrate that the firm's equilibrium inventory stocking policy reflects both the economic logic of the traditional newsvendor inventory model, and the loss‐averse behavior of consumers. The equilibrium order quantity is significantly different from those derived from models that assume that the consumers are risk neutral and homogeneous in their valuations. We show that the firm that ignores strategic consumer's loss‐aversion behavior tends to keep an unnecessarily high inventory level that leads to excessive leftovers. Our numerical experiments further reveal that in some extreme cases the firm that ignores strategic consumer's loss‐aversion behavior generates almost 92% more leftovers than the firm that possesses consumers’ loss‐aversion information and takes it into account when making managerial decisions. To mitigate the consumer's forward‐looking behavior, we propose the adoption of the practice of agile supply chain management, which possesses the following attributes: (i) procuring inventory after observing real‐time demand information, (ii) enhanced design (which maintains the current production mix but improves the product performance to a higher level), and (iii) customized design (which maintains the current performance level but increases the variety of the current production line to meet consumers’ specific demands). We show that such a practice can induce the consumer to make early purchases by increasing their rationing risk, increasing the product value, or diversifying the product line. © 2015 Wiley Periodicals, Inc.

In this article, we consider a loss‐averse newsvendor with stochastic demand. The newsvendor might procure options when demand is unknown, and decide how many options to execute only after demand is revealed. If the newsvendor reserves too many options, he would incur high reservation costs. Yet reserving too few could result in lost sales. So the newsvendor faces a trade‐off between reservation costs and losing sales. When there are multiple options available, the newsvendor has to consider how many units of each to reserve by studying the trade‐off between flexibility and costs. We show how the newsvendor's loss aversion behavior affects his ordering decision, and propose an efficient algorithm to compute his optimal solution in the general case with n options. We also present examples showing how the newsvendor's ordering strategy changes as loss aversion rises. © 2014 Wiley Periodicals, Inc. 62:46–59, 2015 相似文献

This article studies operations sequencing for a multi‐stage production inventory system with lead times under predictable (deterministic) yield losses and random demand. We consider various cases with either full or partial release of work‐in‐process inventories, for either pre‐operation or post‐operation cost structures, and under either the total discounted or average cost criteria. We derive necessary and sufficient criteria for the optimal sequence of operations in all cases. While the criteria differ in their specific forms, they all lead to the same principal: those operations with (1) lower yields, (2) lower processing costs, (3) longer lead times, and (4) lower inventory holding costs should be placed higher upstream in the system.Copyright © 2014 Wiley Periodicals, Inc.

船用核动力装置给水减少事件分析与处置研究 总被引:2,自引:1,他引:1
从船用核动力装置蒸汽发生器给水减少事件出发,建立事件树分析模型,在保证核安全的前提下,以确保反应堆不停堆为约束条件,运用Relap5/Mod3程序对事件演变过程中的热工水力参数进行计算分析,筛选出在不同运行条件下处理该事件的最佳方案。分析结果表明,在反应堆低功率运行时,并不是所用的给水减少均会造成反应堆停堆,存在最佳的处理方案及相对较长的处置时间用以恢复反应堆及蒸汽发生器的正常运行状态。 相似文献

减少航程损失的尾流自导新方案 总被引:2,自引:1,他引:1
提出了一种基于三元换能器组的尾流自导导引方案,它对尾流的左右舷判别能力使其可以采用较小的尾流出入角度,从而可以较大程度降低鱼雷航程损失.仿真结果表明,该方案可以在不降低鱼雷末弹道命中概率的前提下,将尾流导引段的航程损失由通常的15%降低到5%左右. 相似文献

热边界层流动中管道的热损失 总被引:4,自引:4,他引:0
在高粘液体管道输送中,利用热边界层减阻需确定热流量的计算。热边界层流动中管道的各种热损失是总热流量的一部分。热损失有管内、管外及保温层三种形式。管外热损失是向周围的空气散发的,通过对流的形式发生。管内的热损失是导热或对流。保温层的热损失主要是导热。利用热边界层理论的成果,给出了各种传热系数和管道热损失的计算公式,并给出了多个计算实例。 相似文献
