摘要:

时装零售商需要提前近一年对下一季进行准确的需求预测,以便进行需求管理和供应链规划。准确的预测对于确保零售商的盈利能力和减少处理未售出库存造成的环境破坏非常重要。这是具有挑战性的,因为大多数产品是新的,在一个季节,并有很短的生存周期,巨大的销售变化和较长的交货期。在本文中,我们提出了一种新的产品年龄为基础的预测模型,其中产品年龄是指自推出的周数,并表明它优于现有的模型。我们通过一家拥有300多家商店、35 k件商品和大约40个类别的跨国时装零售商的真实用例展示了该方法的强大性能。这项工作的主要贡献包括产品属性值的独特和重要的特征工程,提前6-12个月的准确需求预测,并扩展我们的方法来推荐下一季的产品发布时间。我们使用我们的时装分类优化模型来产生下一季将在商店中列出的物品的列表和数量,以最大化总收入并满足业务约束。我们发现,与零售商的计划相比,我们的框架收入提高了41%。我们还比较了我们的预测结果与现有的方法,并表明它优于现有的模型。我们的框架导致更好的订购,库存规划,分类规划和整体增加利润的零售商的供应链。

英文摘要:

Fashion retailers require accurate demand forecasts for the next season, almost a year in advance, for demand management and supply chain planning purposes. Accurate forecasts are important to ensure retailers' profitability and to reduce environmental damage caused by disposal of unsold inventory. It is challenging because most products are new in a season and have short life cycles, huge sales variations and long lead-times. In this paper, we present a novel product age based forecast model, where product age refers to the number of weeks since its launch, and show that it outperforms existing models. We demonstrate the robust performance of the approach through real world use case of a multinational fashion retailer having over 300 stores, 35k items and around 40 categories. The main contributions of this work include unique and significant feature engineering for product attribute values, accurate demand forecast 6-12 months in advance and extending our approach to recommend product launch time for the next season. We use our fashion assortment optimization model to produce list and quantity of items to be listed in a store for the next season that maximizes total revenue and satisfies business constraints. We found a revenue uplift of 41% from our framework in comparison to the retailer's plan. We also compare our forecast results with the current methods and show that it outperforms existing models. Our framework leads to better ordering, inventory planning, assortment planning and overall increase in profit for the retailer's supply chain.
