摘要：We study a risk-averse newsvendor problem where demand distribution is unknown. The focal product is new, and only the historical demand information of related products is available. The newsvendor aims to maximize its expected profit subject to a profit risk constraint. We develop a model with a value-at-risk constraint and propose a data-driven approximation to the theoretical risk-averse newsvendor model. Specifically, we use machine learning methods to weight the similarity between the new...

摘要：Uncertainties involved in decision making often impose challenges to our ability of modeling and analyzing the reality. The purpose of this study is to demonstrate how one can go beyond the conventional optimization thinking, via taking a stochastic viewpoint, to push the boundaries of the analysis. We review the basic notions of stochastic orders and stochastic functions, with which the conventional (deterministic) way of modeling can be generalized. Based on the orders among distribution fun...

摘要：A common feature to electricity markets with derivative contracts is that the traded contracts are almost only futures and that they are traded multiple times the overall electricity demand. To understand why this occurs in practice, we study the efficiency of risk aligning in the competitive energy industry through derivative contract trading. We derive conditions that need to hold for a contract to provide the most efficient risk aligning, among all possible derivative contracts imaginable. ...

摘要：Consider a single-product, make-to-stock, risk-averse company that manages its finished goods inventory by a basestock policy. Item demand is modeled as a Poisson process, and unit production time is modeled as an exponential random variable. Annual cost is equal to the sum over one year of the inventory-holding and back-ordering costs. The company wants to minimize the annual cost conditional value-at-risk by an appropriate basestock selection called the optimal basestock. After offering evid...

摘要：In some stockout situations, a retailer may be better off declining to fulfill some demand even though it could have been backordered. We study the conditions under which endogenous (retailer-driven) partial backordering is the cost-minimizing strategy in an infinite horizon periodic review inventory system with dual sourcing. At the beginning of each period, the retailer can place two orders. The first order (with higher unit purchase cost) is delivered immediately from the fast supplier and ...

摘要：Business rivals often collaborate on specific aspects of their operations in order to achieve cost efficiency. To better understand and manage such an operational collaboration, we formulate a multi-stage duopoly competition model to study the strategic and welfare implications of a cost-reducing cooperation between competing firms. Without any additional agreement beyond the collaborative effort in deterministic cost reduction, we characterize intuitive conditions under which there exists a u...

摘要：Motivated by several industry examples, we study the interaction between a technology provider introducing a new technology and downstream manufacturers adopting the new technology into their products. The manufacturers, once decided on their adoption timing, both cooperate in making demand-boosting investments to promote the technology and compete in price in the product market. Our main objective is to explore the important question of how the technology provider manipulates manufacturers' a...

摘要：This paper investigates how the optimization of policymaker interventions against an epidemic disease is affected by contextual factors related to (i) a cost-centered approach to countering the epidemic, (ii) eventual correlative popular discontent, and (iii) growing social fatigue engendered by nontherapeutic interventions. Three nontherapeutic policies-mobility restrictions (MR), securing social interactions (SSI), and a combination of both (MR + SSI)-are compared in terms of effectiveness a...

摘要：We study a special class of cooperative games with transferable utility (TU), called m-attribute games. Every player in an m-attribute game is endowed with a vector of m attributes that can be combined in an additive fashion; that is, if players form a coalition, the attribute vector of this coalition is obtained by adding the attributes of its members. Another fundamental feature of m-attribute games is that their characteristic function is defined by a continuous attribute function pi-the va...
