• Catch-Up Scheduling for Childhood Vaccination AI翻译

  摘要：In this paper, we outline the development of the core optimization technology used within a decision support tool to help providers and caretakers in constructing catch-up schedules for childhood immunization. These schedules ensure that a child continues to receive timely coverage against vaccine-preventable diseases in the likely event that one or more doses have been delayed. This project was undertaken as part of a collaborative effort between the Centers for Disease Control and Prevention...
• Selfish Drug Allocation for Containing an International Influenza Pandemic at the Onset AI翻译

  摘要：Recent epidemiologic studies have suggested that the prophylactic use of antiviral drugs could slow down the spread of an influenza epidemic. Because drug stockpiles are presently scattered in different countries, the outbreak of an epidemic gives rise to a game in which each country must make decisions about how best to allocate its own stockpile in order to protect its population. We develop a two-period multivariate Reed-Frost model to represent the spread of the epidemic within and across ...
• A Deterministic Smart Market Model for Groundwater AI翻译
  作者：Raffensperger, John F.; Milke, Mark W.; Read, E. Grant

  摘要：Efficient management of water requires balancing environmental needs, externality considerations, and economic efficiency. Toward that end, this paper presents a deterministic linear program that could be used to operate a smart spot market for groundwater. The market design uses the existing hydrological programs MODFLOW and GWM along with standard linear programming methods. In principle, a market could be set up anywhere that a MODFLOW model is available. The market design has parallels to ...
• Dynamics of New Product Introduction in Closed Rental Systems AI翻译

  摘要：We study a rental system where a fixed number of heterogeneous users rent one product at a time from a collection of reusable products. The online DVD rental firm Netflix provides the motivation. We assume that rental durations of each user are independent and identically distributed with finite mean. We study transient behavior in this system following the introduction of a new product that is desired by all the users. We represent the usage process for this new product in terms of an empiric...
• End-of-Period vs. Continuous Accounting of Inventory-Related Costs AI翻译
  作者：Rudi, Nils; Groenevelt, Harry; Randall, Taylor R.

  摘要：This paper investigates the effect of using an end-of-period accounting scheme for inventory-related costs when costs actually accrue in continuous time. Using a simple model, we show that (i) the end-of-period scheme results in higher than optimal order-up-to levels and inventory cost if the cost and demand parameters are unchanged, and (ii) it is possible to replicate both the optimal base-stock level and its cost by selecting the values of the cost or demand parameters judiciously. The cost...
• Multiattribute Utility Copulas AI翻译
  作者：Abbas, Ali E.
  作者单位：University of Illinois System; University of Illinois Urbana-Champaign
  摘要：We introduce the notion of a multiattribute utility copula that expresses any (i) continuous; (ii) bounded multiattribute utility function that is (iii) nondecreasing with each of its arguments, and (iv) strictly increasing with each argument for at least one reference value of the complement attributes, in terms of single-attribute utility assessments. This formulation provides a wealth of new functional forms that can be used to model preferences over utility-dependent attributes and enables...
• A Decomposition Approach for a Class of Capacitated Serial Systems AI翻译
  作者：Janakiraman, Ganesh; Muckstadt, John A.
  作者单位：New York University; Cornell University
  摘要：We study a class of two-echelon serial systems with identical ordering/production capacities or limits for both echelons. Demands are assumed to be integer valued. For the case where the lead time to the upstream echelon is one period, the optimality of state-dependent modified echelon base-stock policies is proved using a decomposition approach. For the case where the upstream lead time is two periods, we introduce a new class of policies called two-tier base-stock policies, and prove their o...
• Inventory Centralization Games with Price-Dependent Demand and Quantity Discount AI翻译
  作者：Chen, Xin
  作者单位：University of Illinois System; University of Illinois Urbana-Champaign
  摘要：Consider a distribution system consisting of a set of retailers facing a single-period price-dependent demand of a single product. By taking advantage of the risk-pooling effect and the quantity/volume discount provided by suppliers or third-party carriers, the retailers may place joint orders and keep inventory at central warehouses before demand realization, and allocate inventory among themselves after demand realization to reduce their operating costs. Under rather general assumptions, we ...
• Dynamic Pricing Without Knowing the Demand Function: Risk Bounds and Near-Optimal Algorithms AI翻译
  作者：Besbes, Omar; Zeevi, Assaf
  作者单位：University of Pennsylvania; Columbia University
  摘要：We consider a single-product revenue management problem where, given an initial inventory, the objective is to dynamically adjust prices over a finite sales horizon to maximize expected revenues. Realized demand is observed over time, but the underlying functional relationship between price and mean demand rate that governs these observations (otherwise known as the demand function or demand curve) is not known. We consider two instances of this problem: (i) a setting where the demand function...
• The Impact of Oligopolistic Competition in Networks AI翻译
  作者：Cominetti, Roberto; Correa, Jose R.; Stier-Moses, Nicolas E.
  作者单位：Universidad de Chile; Universidad de Chile; Columbia University
  摘要：In the traffic assignment problem, first proposed by Wardrop in 1952, commuters select the shortest available path to travel from their origins to their destinations. We study a generalization of this problem in which competitors, who may control a nonnegligible fraction of the total flow, ship goods across a network. This type of games, usually referred to as atomic games, readily applies to situations in which the competing freight companies have market power. Other applications include inte...
