摘要：Problem definition: Appointment scheduling problems under uncertainty encounter a fundamental trade-off between cost minimization and customer waiting times. Most existing studies address this trade-off using a weighted sum approach, which puts little emphasis on individual waiting times and, thus, customer satisfaction. In contrast, we study how to minimize total cost while providing waiting time guarantees to all customers. Methodology/results: Given box uncertainty sets for service times an...

摘要：Problem definition: Many shared resources, such as hotel rooms or rental cars, require cleaning, charging, or some other operation to turn around the resources between successive customer uses. We study staffing and shift planning decisions for the turnaround service capacity in order to minimize the sum of customer waiting and staffing costs. Stochastic customer arrival and departure patterns, coupled with worker shifts with breaks, add to the managerial challenge. Methodology/results: Using ...

摘要：Problem definition: We study the problem of finding the optimal assortment that maximizes expected revenue under the decision forest model, a recently proposed nonparametric choice model that is capable of representing any discrete choice model and in particular, can be used to represent nonrational customer behavior. This problem is of practical importance because it allows a firm to tailor its product offerings to profitably exploit deviations from rational customer behavior, but at the same...

摘要：Problem definition: We consider a newsvendor problem with unknown demand distribution, where we distinguish ambiguity under which the newsvendor does not differentiate demand distributions of common characteristics (e.g., mean and variance) and misspecification under which such characteristics might be misspecified (because of, e.g., estimation error and/or distribution shift). Methodology/results: The newsvendor hedges against ambiguity and misspecification by maximizing the worst-case expect...

摘要：Problem definition: Interest rates on loans are often influenced by market prospects. Under asymmetric information, firms may attempt to signal strong prospects to lenders by over-borrowing. However, publicly revealing confidence in the market can also intensify competition. Motivated by these observations, we examine a firm's financing and information disclosure strategy. Methodology/results: We develop a game-theoretical model where a firm with private information about the market prospect c...

摘要：Problem definition: How should online retailers make demand predictions or operational decisions with limited relevant data? Motivated by conventional data aggregation approaches, we develop a flexible data aggregation (FlexDA) framework to adapt to different degrees of heterogeneity across products, thereby striking a better balance between the bias and variance of data-driven predictions and decisions. Methodology/ results: Under the FlexDA framework, we propose aggregating the individual da...

摘要：Problem definition: Rational analysis predicts that the cost of queuing depends on the remaining wait time, but research suggests that other parameters such as queue length, service speed, experienced length, and elapsed wait also matter. However, it is challenging to isolate the distinct contribution of these parameters on a monetarily translatable metric because of uncertainty, missing controls in analyses that may lead to omitted variable bias, and differences in outcome variables across ex...

摘要：Problem definition: We examine moviegoers' choices between consuming content via legal theatrical channels and illegal piracy channels. We focus on how two important factors affect this choice: the picture quality of piracy sources (a function of studio security investments) and the costs associated with legal channels, including consumer transportation costs (a function of screening volumes) and ticket prices. Methodology/ results: We formulate a structural model and conduct counterfactual si...

摘要：Problem definition: This paper considers the operations management problems under a newly proposed choice model referred to as a focal multinomial logit (FMNL) model. It generalizes the famous multinomial logit (MNL) model and various well-studied consideration-set choice models and can effectively capture irrational choice behaviors such as the context effect, halo effect, and choice overload, as well as the effect of focality. Methodology/results: We focus on the threshold focal set and vari...
