摘要：A buyer faces a two-dimensional mechanism design problem for awarding a project to one among a set of contractors, each of whom is privately informed about the contractor's cost and the contractor's estimate of an a priori random noncost attribute. The winning contractor realizes the noncost attribute upon the project's completion and may manipulate it in a costless manner (if such a manipulation is beneficial to the contractor). The noncost attribute inflicts a disutility cost on the buyer. T...

摘要：Sales and operations planning processes are used to align production quantities and customer demand. Two key activities of these processes are demand planning and production planning, which are often assigned to individuals in different departments. Production planning requires accurate demand forecasts from demand planning to be able to choose proper production quantities, but demand planners have to invest effort to create accurate demand forecasts. We study the role of social preferences (a...

摘要：Consider a publisher of online display advertising that sells its ad resources in both an up-front market and a spot market. When planning its ad delivery, the publisher needs to make a trade-off between earning a greater short-term profit from the spot market and improving advertising effectiveness in the up-front market. To address this challenge, we propose an integrated planning model that is robust to the uncertainties associated with the supply of advertising resources. Specifically, we ...

摘要：Motivated by the challenges faced by firms entering an unknown market, we study a strategic investment problem in a duopoly setting. The favorableness of the market is unknown to both firms, but firms have prior information about it. A leader invests first by choosing its investment size. Then, in a continuous-time Bayesian setting, a competitive follower dynamically learns about the favorableness of the market by observing the leader's earnings and chooses its investment size and timing. In t...

摘要：We present a formal study of first-look and preferred deals that are a recently introduced generation of contracts for selling online advertisements, which generalize traditional reservation contracts and are suitable for advertisers with advanced targeting capabilities. Under these deals, one or more advertisers gain priority access to an inventory of impressions before others and can choose to purchase in real time. In particular, we propose constant-factor approximation algorithms for maxim...

摘要：Every year, tens of thousands of refugees are resettled to dozens of host countries. Although there is growing evidence that the initial placement of refugee families profoundly affects their lifetime outcomes, there have been few attempts to optimize resettlement decisions. We integrate machine learning and integer optimization into an innovative software tool, Annie (TM) Matching and Outcome Optimization for Refugee Empowerment (Annie (TM) MOORE), that assists a U.S. resettlement agency with...

摘要：This paper is a retrospective look at 68 years of publication output of Operations Research, revealing changes in its publications, its authors, and their impact over time and how these changes might affect researchers and practitioners in the present. A total of 5,440 journal articles from its inception in 1952 to 2019 are used. The analysis initially focuses on the most studied topics and then continues with the top research methods and research problems investigated. The top contributing co...

摘要：We develop a variant of the multinomial logit model with impatient customers and study assortment optimization and pricing problems under this choice model. In our choice model, a customer incrementally views the assortment of available products in multiple stages. The patience level of a customer determines the maximum number of stages in which the customer is willing to view the assortments of products. In each stage, if the product with the largest utility provides larger utility than a min...

摘要：Shi and acute accent Olafsson [(2000) Nested Partitions Method for Global Optimization. Operations Research. 48(3):390-407] proposed the Nested Partitions (NP) method with two different NP backtracking rules-namely, NP I and NP II-for solving global optimization problems. Two of their main results are the properties of the global convergence of the NP method stated in theorems 3 and 4 on pages 398 and 399, respectively. In particular, theorem 3 provides a hitting-probability-based formula to r...

摘要：We investigate the stability condition of redundancy-d multiserver systems. Each server has its own queue and implements popular scheduling disciplines such as first-come-first-serve (FCFS), processor sharing (PS), and random order of service (ROS). New jobs arrive according to a Poisson process, and copies of each job are sent to d servers chosen uniformly at random. The service times of jobs are assumed to be exponentially distributed. A job departs as soon as one of its copies finishes serv...
