Prof. Xiaoqiang CaiChinese University of Hong KongTalk: Optimization and Coordination of Supply Chains of Fresh Products Requiring Long-distance TransportationAbstract:Fresh-food supply chains have the distinct feature that the production and the market are often vastly separate. As a consequence, long distance transportation is usually inevitable, during which the product may suffer both quali...

Prof. Fangruo ChenColumbia UniversityTalk: Warranty Costs Sharing in a Supply ChainAbstract:We consider a supply chain where a buyer (manufacturer) sources a component from multiple suppliers. The buyer uses the component to make a product that she sells to end customers. When the component fails in the field, warranty costs are incurred. We are interested in understanding how the way the warra...

Prof. Hong ChenUniversity of British Columbia and China Europe International Business SchoolTalk: Joint Pricing and Inventory Control with General Additive DemandAbstract: We study a periodic-review, discounted-expected-profit maximization problem for a firm who faces price-sensitive random demand over a finite horizon. Any unsatisfied demand is backlogged. The inventory cost is quasi-convex. W...

Prof. Albert HAHong Kong University of Science and TechnologyTalk: Information Sharing in Supply Chains under CompetitionAbstract: We will present the results of some current research on information sharing in supply chains under competition. We will consider two supply chain structures. The first one concerns with two supply chains each consisting of one manufacturer selling to one retailer an...

Prof. Retsef LeviMassachusetts Institute of TechnologyTalk: Approximation Algorithms for Multistage Stochastic Control ModelsAbstract:Multistage stochastic control models arise in various application domains, including central areas of operations management, such as inventory control, supply chain management and revenue management. Unfortunately, it is usually computationally very hard to find ...

Prof. Qian LiuHong Kong University of Science and TechnologyTalk: Dynamic Pricing Competition with Strategic Customers under Vertical Product DifferentiationAbstract:We consider multi-period dynamic pricing competition between two sellers offering vertically differentiated products to strategic customers that are inter-temporal utility maximizers. Our model can be viewed as an extension of the ...

Prof. Özalp ÖZERThe University of Texas at DallasTalk: Forecast Information Sharing: The Role of Contracts, Behaviors and TimingAbstract:In this presentation, we will focus on the problem of a supplier soliciting forecast information from a manufacturer. We will show that a wholesale price contract leads to a forecast communication that is non-binding, non-verifiable and costless (also known as...

Prof. Georgia PerakisMassachusetts Institute of TechnologyTalk: Price of Price-only Contracts in Competitive Supply Chains when Pricing is EndogenousAbstract:In this work, we investigate a two-tier supply chain in which there is a supplier who proposes a simple price-only contract to several sellers who are competing in the market through selling differentiated products to customers. The goal i...

Prof. Max Zuo-Jun ShenUniversity of California at BerkeleyTalk: Decision Making with Limited InformationAbstract:I will discuss two recent papers, both of which have something to do with decision making with limited information. In the first half of the talk, I will present a dynamic assortment optimization. Given the limited store capacity, a retailer must decide which products to offer to cus...

Prof. Biying ShouCity University of Hong KongTalk: Managing supply uncertainty under chain-to-chain competitionAbstract:We study the competition of two supply chains with supply uncertainty. We examine the supply chain decisions at three different levels. At the operational level, we show that retailer should order more (less) if its competing retailer has a less (more) reliable supply. At the ...

Prof. Melvyn SimNational University of SingaporeTalk: Dual representation of choice and aspirational preferencesAbstract:We consider choice over a set of monetary acts (random variables) and study a general class of preferences. These preferences favor diversification, except perhaps on a subset of sufficiently disliked acts, over which concentration is instead preferred. This structure encompa...

Prof. Jeannette SongDuke UniversityTalk: Supply StreamsAbstract:A supply stream is a continuous version of a supply chain. It is like a series inventory system,  but stock can be held at any point along a continuum, not just at discrete stages. We assume stationary parameters, and we focus on stationary echelon base-stock policies, which are known to be optimal for discrete stages. We show that...
