AI总结:

针对资金受限线上零售商的多产品库存问题,构建含订单贷款的随机规划模型,结合情景树与约简技术求解,验证了模型优于确定性模型且明确了贷款使用的适用场景。

摘要:

本文研究了一类多产品随机库存问题,其中资金受限的线上零售商可采用中国部分电商平台提供的order-based loan(订单贷款),加快递延收益的资金回笼速度。我们首先为该问题构建确定性模型,随后建立对应的随机规划模型,以最大化零售商在规划周期内的期望利润。客户需求的不确定性通过情景树刻画,当情景树规模过大时,采用情景约简技术求解问题。我们基于从某线上店铺爬取的真实数据开展数值测试。结果表明,随机模型的表现优于确定性模型,尤其在零售商资金受限程度较低时优势更明显。此外,当零售商初始可用资金较少,或面临较长的收款延迟周期时,更倾向于选择使用订单贷款。

英文摘要:

This paper investigates a multi-product stochastic inventory problem in which a cash-constrained online retailer can adopt order-based loan provided by some Chinese e-commerce platforms to speed up its cash recovery for deferred revenue. We first build deterministic models for the problem and then develop the corresponding stochastic programming models to maximize the retailers' expected profit over the planning horizon. The uncertainty of customer demand is represented by scenario trees, and a scenario reduction technique is used to solve the problem when the scenario trees are too large. We conduct numerical tests based on real data crawling from an online store. The results show that the stochastic model outperforms the deterministic model, especially when the retailer is less cash-constrained. Moreover, the retailer tends to choose using order-based loan when its initial available cash is small or facing long receipt delay length.
