Managing Product-Reusability Under Supply Disruptions
研究了企业在供应中断风险下如何通过翻新策略管理产品可重复使用性，发现高风险时增加可重复使用性有利，但超过阈值后降低可重复使用性反而更盈利。
We analyze product reusability, executed through refurbishment, amid supply disruptions. Consumers trade in used units, which can later be refurbished and sold. Using a three-period model, we determine the optimal reusability level, trade-in and refurbishment policies, trade-in fee, and the prices of new and refurbished units. Our analysis provides a useful framework to understand the interaction between a firm's choice of product reusability and the possibility of supply disruptions. First, we establish a threshold refurbishment policy: the firm refurbishes more as reusability increases but avoids refurbishment at low reusability. When both consumer valuation of used units and supply disruption probability are high, the firm builds a safety-stock of traded-in units, which it refrains from refurbishing when there is no supply disruption, unless the product reusability level is sufficiently high. Second, we find that it benefits to increase product reusability as the supply disruption risk increases until a certain threshold. Beyond this threshold, it is advantageous for the firm to reduce reusability and save on design costs to be profitable, contrary to popular belief. Our numerical examples reveal that the firm reduces reusability when production cost is high due to narrow margins. Finally, we demonstrate that the firm shares the benefits of higher product reusability with its consumers through higher trade-in fees and lower refurbished unit prices. This results in a “Pareto-efficient” win for the firm, its trade-in customers, and purchasers of refurbished units. Thus, our analysis offers insights for product designers on how supply disruption influences reusability choices in products.
