摘要:

We study a multilocation newsvendor model with a retailer owning multiple retailing stores, each of which is managed by a manager who decides its order quantity for filling random customer demand of a product. The store managers and the retailer are all risk-averse while the managers are more risk-averse than the retailer. We adopt conditional value-at-risk (CVaR) as the performance measure and consider two alternative strategies to improve the performance of the system. First, the retailer centralizes the ordering decisions. Second, the managers still decide the order quantity for their own store whereas their inventories are pooled together. We compare the optimal order quantities and the resulting CVaR values of the systems and study their comparative statistics. We find that when there is no inventory pooling, each store has a higher inventory level in the centralized system than in the decentralized system. More interestingly, centralization brings positive benefits to the retailer as long as some store manager(s) is strictly more risk-averse than the retailer. When there is inventory pooling, if the store managers are sufficiently more risk-averse than the retailer or the demands are very heavy-tailed, we find that inventory pooling brings less benefit than centralization. In our numerical study, we first employ data from an online retailer in China to validate our analytical results. Then we use simulated data to further show that both the benefit of centralization and the benefit of inventory pooling increase as the product price, the number of stores, or the demand variance increases; for positively correlated demands, it is more likely that centralization brings more benefit than inventory pooling; and centralization and inventory pooling could be either strategic complements or substitutes. This is joint work with Zhenyu Hu (NUS) and Chaolin Yang (SUFE)
