摘要：The chaotic response of the US Strategic National Stockpile to COVID-19 during 2020 highlighted the inadequacy of the inventory-based approaches to disaster response. This paper examines the integration of stockpile inventory, backup capacity, and standby capability to meet the disaster-related surge in demand in the future. We present a two-period model of such an integrated system for consumable items with uncertain demand that follows a general probability distribution. Our model incorporat...

摘要：Buy-one-get-one-free (BOGOF), a ubiquitous sales promotion scheme by which consumers get two items for the price of one, encourages consumers to buy and waste food. An alternative promotional scheme is one where consumers receive a coupon for a second item available for free at a later time. Our work is motivated by British supermarkets which, facing criticism from lawmakers for running BOGOF promotions on perishables, started a BOGOF Later campaign with the claim that it would reduce the amou...

摘要：We consider an inventory system with Poisson demand arrivals arising from multiple classes. Restocking epochs are specified by a given sequence. At each epoch, we can place an order for any number of items for immediate delivery. We have to decide the inventory dispensation policy, which determines whether we should satisfy a demand, or reject it, or backlog it until the next restocking epoch. We allow class-dependent rejection and backlogging costs. We also incorporate holding costs and procu...

摘要：Auto-delivery is a subscription model widely employed in supply chains, whereby a supplier delivers products to a buyer (or multiple buyers) according to the buyer's choice of a constant shipping quantity to be delivered at prescheduled dates. The buyer enjoys a discount for the auto-delivery orders and other benefits, including free subscription and cancellation. Because these benefits seem to all accrue to the buyer at the supplier's expense, the rationale for the supplier's decision to offe...

摘要：This paper proposes price cannibalization as a growth strategy despite prior findings that suggests avoiding it. We focus on a multiclass, capacity-constrained pricing problem in which each of the product classes has a price range. Specifically, we examine the effects of price range overlaps and introduce it as a revenue-maximizing pricing strategy. Price cannibalization happens when sales in some product classes decrease due to the existence of overlaps between the price ranges. We employ a m...

摘要：We study the design of crowdsourcing contests in settings where the outputs of the contestants are quantifiable, for example, a data science challenge. This setting is in contrast to those where the output is only qualitative and cannot be objectively quantified, for example, when the goal of the contest is to design a logo. The literature on crowdsourcing contests focuses largely on ordinal contests, where contestants' outputs are ranked by the designer and awards are based on relative ranks....

摘要：Fixed costs of ordering items or setting up a production process arise in many real-life scenarios. In their presence, the most widely used ordering policy in the stochastic inventory literature is the (s, S) policy. Optimality of (s, S) policies and (s, S)-type policies have been examined for various inventory models, including those with the inventory level being reviewed in every period or continuously, finite and infinite horizons, discounted-cost and average-cost criteria, backlogging and...

摘要：Our research investigates a joint inventory replenishment and pricing problem, where a seller controls the price of a leading product while restocking for all the products. We demonstrate that the seller's expected value functions present an L-(sic)-concave structure, recommending an optimal order-up-to inventory-level and list-price policy. Our findings reveal divergent economic relationships between products from the seller's and customer's perspectives, suggesting managers broaden their str...

摘要：We study the robust production and maintenance control for a production system subject to degradation. A periodic maintenance scheme is considered, and the system production rate can be dynamically adjusted before maintenance, serving as a proactive way of degradation management. Optimal control of the degradation rate aims to strike a balance between the risk of failure and the production profit. We first consider the scenario in which the degradation rate increases linearly with the producti...

摘要：This paper introduces the general philosophy of the Operational Data Analytics (ODA) framework for data-based decision modeling. The fundamental development of this framework lies in establishing the direct mapping from data to decision by identifying the appropriate class of operational statistics. The efficient decision making relies on a careful balance between data integration and decision validation. Through a canonical decision making problem under uncertainty, we show that the existing ...
