摘要：Firms that sell products over a limited selling season often have only imperfect information about (a) the exact timing of that season, (b) the demand volume to expect, and (c) the temporal distribution of demand over the selling season. Given these uncertainties, firms must determine not only how much inventory to stock but also when to make that inventory available to customers. We thus ask: What is a firm's optimal inventory quantity and timing for products sold during a stochastic selling ...

摘要：This work explores the admission and capacity allocation for a leasing system with two types of equipment and three kinds of batch demands: elementary specified, premium specified, and unspecified demands. The demands arrive following mutually independent Poisson processes, and the rental duration of equipment follows a negative exponential distribution. The lessor can satisfy partially the specified demands with the required type of equipment and satisfy partially the unspecified demands with...

摘要：We study a finite horizon, single product, periodic review inventory system with two supply sources and a salvage option. These supply sources are typically capacitated and capacity levels often need to be reserved or installed in advance of the operational planning horizon. The supply sources may thus be differentiated by their lead times, capacities, and fixed and variable order costs. Salvage options allow for inventory reductions and incur fixed cost and variable revenues. We first analyze...

摘要：Large-scale production of a new vaccine, such as the COVID-19 vaccine, is characterized by evolving demand and production yield uncertainties. Further, following its FDA approval for efficacy and safety, a vaccine may not even be manufacturable due to its low production yield and the resulting lack of profitability. To deal with those challenges in practice, a vaccine manufacturer can (stochastically) increase the uncertain yield of a vaccine prior to launching large-scale production by learni...

摘要：One of the most popular ways of shopping in an omnichannel retailing environment is buy-online-pickup-in-store (BOPS). Retailers often promise BOPS shoppers short in-store pickup ready times. We study fulfillment scheduling decisions of BOPS orders destined for a single store of a retailer. There are two fulfillment options for BOPS orders: they can be either processed at a fulfillment center (FC) and delivered to the store or processed at the store without needing delivery. There are two type...

摘要：R&D projects in small biotechnology firms frequently involve knowledge from multiple technical fields and research in different problem domains. An increase in project knowledge scope, defined as the number of technical fields an R&D project covers, can be challenging for resource-constrained small firms. These firms often rely primarily on their principal investigators (PIs), who act as heavyweight project managers in guiding project ideas to successful R&D outcomes. PIs also work concurrentl...

摘要：As the ongoing battle between brick-and-mortar stores and e-commerce shops escalates, managers of the former are becoming more cautious regarding their strategic store site selection and decoration decisions, particularly if foreseeable competition from rival companies exists. This paper investigates a bilevel competitive facility location (BCFL) problem, where two companies, a leader and a follower, plan to enter a market sequentially. Each company has a budget to open and design facilities. ...

摘要：Strategic customers typically patronize service systems at a higher rate than the socially optimal one. Much literature has focused on inducing customers to join such systems at this latter rate. This entire literature considers nonidling policies that are the focus of queueing theory. We demonstrate that strategically imposing delays into service systems can improve the social welfare using the M/G/1 queue with orbit. This versatile queueing model has been extensively studied from a performan...

摘要：This paper studies whether risky borrowing will induce a supplier to expand capacity and thus mitigate a capacity underinvestment problem in supply chains. It demonstrates that the relationship between capacity and capital structure is not as simple as the existing literature suggests. If the supplier is very powerful, it will use a mixed capital structure and build less capacity than if it were equity financed. If the buyer is very powerful, the supplier will use all debt financing and overbu...

摘要：The shipping industry touches approximately 90% of all international trade, producing roughly one billion tons of greenhouse gases each year. Changes in the operations and coordination of global-shipping vessels can have a substantial impact on vessel's carbon emissions, but these efforts need to fulfill the service expectation of individual firms receiving consignments. We examine the associated gains (or losses) in operational efficiencies and environmental benefits (if there are any) from v...
