摘要：We consider a resource allocation problem that combines three general features: complex resource constraints, weak priority rankings over the agents, and ordinal preferences over bundles of resources. We develop a mechanism based on a new concept called competitive stable equilibrium. It has several attractive properties, commonly captures two different frameworks of one-sided and two-sided markets, and extends them to richer environments. Our framework also allows for an alternative and more ...

摘要：In this work we present an equilibrium formulation for price impacts. This is motivated by the Buhlmann equilibrium in which assets are sold into a system of market participants, for example, a fire sale in systemic risk, and can be viewed as a generalization of the Esscher premium. Existence and uniqueness of clearing prices for the liquidation of a portfolio are studied. We also investigate other desired portfolio properties including monotonicity and concavity. Price per portfolio unit sold...

摘要：We study how retailers can use data aggregation and clustering to improve demand prediction. High accuracy in demand prediction allows retailers to effectively manage their inventory as well as mitigate stock-outs and excess supply. A typical retail setting involves predicting demand for hundreds of items simultaneously. Although some items have a large amount of historical data, others were recently introduced and, thus, transaction data can be scarce. A common approach is to cluster several ...

摘要：In this paper, monetary risk measures that are positively superhomogeneous, called star-shaped risk measures, are characterized and their properties are studied. The measures in this class, which arise when the subadditivity property of coherent risk measures is dispensed with and positive homogeneity is weakened, include all practically used risk measures, in particular, both convex risk measures and value-at-risk. From a financial viewpoint, our relaxation of convexity is necessary to quanti...

摘要：Testing a large variety of different product concepts is an integral part of nearly all new product development initiatives???especially in the concept selection phase, where firms seek to identify the most promising concept for further development. Test results are usually collected by agents, who must be incentivized not only to exert effort in testing the concepts but also to report their findings truthfully. We ask: How should a firm structure its concept testing processes when testing eff...

摘要：The growing popularity of bike-sharing systems around the world has motivated recent attention to models and algorithms for their effective operation. Most of this literature focuses on their daily operation for managing asymmetric demand. In this work, we consider the more strategic question of how to (re)allocate dock-capacity in such systems. We develop mathematical formulations for variations of this problem (either for service performance over the course of one day or for a long-run-avera...

摘要：We consider the problem of online job scheduling on a single machine or multiple unrelated machines with general job and machine-dependent cost functions. In this model, each job has a processing requirement and arrives with a nonnegative nondecreasing cost function and this information is revealed to the system on arrival of that job. The goal is to dispatch the jobs to the machines in an online fashion and process them preemptively on the machines to minimize the generalized integral complet...

摘要：We study the revenue volatility of a monopolist selling a divisible good to consumers in the presence of local network externalities among consumers. The utility of consumers depends on their consumption level as well as those of their neighbors in a network through network externalities. In the eye of the seller, there exist uncertainties in the network externalities, which may be the result of unanticipated shocks or a lack of exact knowledge of the externalities. However, the seller has to ...

摘要：We consider the data-driven newsvendor problem in which a manager makes inventory decisions sequentially and learns the unknown demand distribution based on observed samples of continuous demand (no truncation). We study the widely used sample average approximation (SAA) approach and analyze its performance with respect to regret, which is the difference between its expected cost and the optimal cost of the clairvoyant who knows the underlying demand distribution. We characterize how the regre...

摘要：We propose a new approach for the vehicle routing problem with stochastic customer demands revealed before vehicles are dispatched. We combine ideas from vehicle routing and manufacturing process flexibility to propose overlapped routing strategies with customer sharing. We characterize the asymptotic performance of the overlapped routing strategies under probabilistic analysis while also providing an upper bound on the asymptotic performance that depends only on the mean and standard deviatio...
