A critical assumption in the vast literature on inventory management has been that the current level of inventory is known to the decision maker. Some of the most celebrated results such as the optimality of base-stock policies have been obtained under this assumption. Yet it is often the case...

We study a firm's optimal transshipment problem considering the impacts of setup costs for transshipment and demand distribution shapes. We assume that the demand follows a three-point distribution, which changes from a degenerate distribution, to a unimodal distribution, and to a bimodal...

We analyze a price-setting news-vendor problem with an additive – multiplicative demand. We show that the uni-modality of the news-vendor profit function holds when the underlying random term has an increasing failure rate and the demand functions satisfy certain concavity conditions....

This paper proposes a new methodology to solve partially observed inventory problems. Generally, these problems have infinite dimensional states that are conditional distribution of the inventory level. Our methodology involves linearizing the state transitions via unnormalized probabilities. It...

In the Online-to-Offline (O2O) ecommerce model, one challenge facing the online business is to predict customers' future purchases towards each product or subcategory of products, and consequently, coordinate the large amount of offline businesses involved. The main obstacle in doing that...
