摘要：We consider the classical appointment scheduling problem that does not have a session length constraint. The decision is to determine job allowances to minimize total expected weighted costs of waiting times of jobs and idle times of the service provider. In particular, we study a simple yet effective scheduling policy-the so-called constant policy, which allocates a constant job allowance for each appointment. Prior studies on appointment scheduling suggest a dome-shaped structure for the opt...

摘要：In laboratory experiments, we compare the performance of short-term and long-term contracts in a two-period supplier-buyer dyad with asymmetric cost information. We find that buyers tend to reject offers if the payoff inequality increases from one period to the next. We coin this dynamic form of inequity aversion as ratcheting aversion. We show that under short-term contracting, the buyer's ratcheting aversion limits the supplier's leeway to exploit information revelation in earlier periods be...

摘要：In this study, we examine whether it is optimal to use electric vehicles (EVs) in the car sharing market and investigate the environmental impact of pulling the EVs from the market. We develop a model consisting of a profit-maximizing car sharing company (CSC) and a population of utility-maximizing customers. The CSC sets the number of EVs, the number of fuel vehicles (FVs), and the rental price jointly to maximize its profit. Customers decide whether to use EVs, FVs, or public transportation ...

摘要：Initial deployment decisions are critical to humanitarian organizations as they pre-position resources and prepare for predictable disasters, such as hurricanes, floods, and wildfires. Deploying too few resources results in unmet demand, bad publicity, and unhappy donors. However, deploying a large number of resources can also result in bad publicity and unhappy donors due to high costs and wasted resources when disasters do not occur as expected and deployed items are not managed efficiently....

摘要：Motivated by dual sales channel operations in cross-border e-commerce, we analyze an e-tailer's strategic waiting decision for channel disruption information in a global supply chain. The e-tailer operates two sales channels: a bonded-warehouse channel with products prestocked before channel disruption for demand fulfillment; and a direct-shipping channel with products delivered directly from an overseas supplier. The direct-shipping channel is exposed to disruption risk that might be caused b...

摘要：Popular tariffs in the telecommunications market, such as three-part tariffs and flat-rate plans, specify an allowance below which customers enjoy a free and high-quality service. When they consume beyond the allowance, customers either need to pay for the overage (under three-part tariffs) or receive a degraded service (under flat-rate plans), thus experiencing an overage disutility. Some network service providers have recently begun to allow data trading among their subscribers, who can now ...

摘要：We consider a periodic-review perishable inventory system with multiple demand classes, each characterized by a different lost-sales cost and the least freshness requirement. Demands of different classes in the same period could be correlated, while demands across periods are independent but not necessarily identical. In each period, the firm jointly makes the decisions regarding demand fulfillment, production/ordering, and disposal. The objective is to minimize the total discounted expected c...

摘要：We consider a surgical case scheduling problem with the objective of minimizing the expected time span of the schedule subject to a prespecified upper bound on the expected waiting time for each patient. The problem is challenging due to its combinatorial and nonlinear nature, and we focus on developing approximate methods to solve the problem. Specifically, we study two approximation methods. In the certainty equivalent method, we approximate the expected time span of the cases by assuming th...

摘要：Recent advancements in Information Technology have provided an opportunity to significantly improve the effectiveness of inventory systems. The use of in-cycle demand information enables faster reaction to demand fluctuations. In particular, for the newsvendor (NV) system, we exploit the newly available data to perform an additional review (AR) of inventory at an endogenously determined, a priori set time during the sales period, and perform an additional replenishment if necessary. We impleme...
