摘要：We study the effects of rescheduling on no-show behavior in an outpatient appointment system for both new and follow-up patients. Previous literature has primarily focused on new patients and investigated the role of waiting time on no-show probability. We offer a more nuanced understanding of this costly phenomenon. Using comprehensive clinical data, we demonstrate that for follow-up patients, their no-show probability decreases by 10.9 percentage points if their appointments were rescheduled...

摘要：Problem definition: We study the practice-motivated problem of dynamically procuring a new, short-life-cycle product under demand uncertainty. The firm does not know the demand for the new product but has data on similar products sold in the past, including demand histories and covariate information such as product characteristics. Academic/practical relevance: The dynamic procurement problem has long attracted academic and practitioner interest, and we solve it in an innovative data-driven wa...

摘要：We study a newsvendor problem with profit risk control using value-at-risk (VaR) constraints. When a firm's demand correlates with the price of a tradable financial asset, both financial tools (derivatives) and operational tools (inventory) can be used for profit risk management. Such integrated risk management (IRM) approaches have been studied using various optimization frameworks to reflect the risk aversion of decision-makers. To the best of our knowledge, we are the first to study IRM in ...

摘要：Problem definition: Inspired by new developments in dynamic spectrum access, we study the dynamic pricing of wireless Internet access when demand and capacity (bandwidth) are stochastic. Academic/practical relevance: The demand for wireless Internet access has increased enormously. However, the spectrum available to wireless service providers is limited. The industry has, thus, altered conventional license-based spectrum access policies through unlicensed spectrum operations. The additional sp...

摘要：Ticket queues are prevalent in service industries. They enhance customer satisfaction by eliminating physical lines but may compromise efficiency. Existing studies offer mixed results on the cause and magnitude of such inefficiency. These results, however, are based on simplistic customer behaviors. Taking a holistic approach, we examine how realistic customer behaviors drive ticket queue performance. Our empirical studies reveal that (i) customers are capable of adapting their patience to the...

摘要：Problem definition: We analyze a new model of crowdfunding recently introduced by Bolstr, Localstake, and Startwise. A platformacts as a matchmaker between a firm needing funds and a crowd of investors willing to provide capital. After the firm is funded, it pays back the investors using revenue-sharing contracts, with a prespecified investment multiple (investors will receive M >= 1 dollars for every dollar invested) and a revenue-sharing proportion, over an investment horizon of uncertain du...

摘要：Problem definition: Inpatient beds are usually grouped into several wards, and each ward is assigned to serve patients from certain primary specialties. However, when a patient waits excessively long before a primary bed becomes available, hospital managers have the option to assign her to a nonprimary bed. although it is undesirable. Deciding when to use such overflow is difficult in real time and under uncertainty. Relevance: To aid the decision making, we model hospital inpatient flow as a ...

摘要：Problem definition: How to dynamically replenish inventory from two supply sources or shipping modes with general lead times. The fast source is more expensive than the slow source. Academic/practical relevance: Dual sourcing provides supply chain flexibility to mitigate demand and supply risk. Despite its relevance in practice, characterizing the optimal dual sourcing policy is extremely challenging, and the optimal stochastic policy for nonconsecutive lead times has been unknown for over 50 ...
