  摘要：We consider two competing supply chains, each consisting of supplier, a manufacturer, and a retailer. The suppliers exert effort to improve product quality, and the retailers sell products competitively. Each manufacturer chooses one of the three strategies: forward integration, backward integration, or no vertical integration. We seek for a subgame perfect Nash equilibrium and study the resulting market structure. Moreover, we characterize the effect of vertical integration on profitability, ...
• Quality Testing and Product Rationing by Input Suppliers AI翻译

  摘要：Quality testing by suppliers has significant ramifications for downstream supply chain participants and retail consumers. This article focuses on such implications accounting for the fact that suppliers often enjoy discretion in quality testing and reporting. Under a discretionary testing and reporting environment, we show that a supplier can improve the market's perception of product quality by engaging in self-imposed production cuts. Production cuts dampen supplier incentives to engage in e...
• The Design and Introduction of Product Lines When Consumer Valuations are Uncertain AI翻译

  摘要：This article presents a model of the design and introduction of a product line when the firm is uncertain about consumer valuations for the products. We find that product line introduction strategy depends on this uncertainty. Specifically, under low levels of uncertainty the firm introduces both models during the first period; under higher levels of uncertainty, the firm prefers sequential introduction and delays design of the second product until the second period. Under intermediate levels ...
• Supply-Chain Research Opportunities with the Poor as Suppliers or Distributors in Developing Countries AI翻译

  摘要：Many social enterprises and some companies have developed supply chains with the poor as suppliers or distributors to alleviate poverty and to create revenues for themselves. Such supply chains have created new research opportunities because they raise issues fundamentally different from those examined in the existing operations management literature. We report this phenomenon of supply chains with the poor as suppliers or distributors in developing countries and identify operations management...
• Is Safe Production an Oxymoron? AI翻译

  摘要：This research examines how organizations simultaneously manage their operations and occupational health and safety. Although both safety and operations scholars conduct research in the same operational settings, they have reached different, yet untested, conclusions about the relationship between creating a safe workplace and creating a productive workplace. The results from a series of 10 case studies show that it is possible to create safe and productive workplaces, but that many facilities ...
• Assessing Trade-offs among Multiple Objectives for Humanitarian Aid Delivery Using Expert Preferences AI翻译

  摘要：Humanitarian aid agencies deliver emergency supplies and services to people affected by disasters. Scholars and practitioners have developed modeling approaches to support aid delivery planning, but they have used objective functions with little validation as to the trade-offs among the multiple goals of aid delivery. We develop a method to value the performance of aid delivery plans based on expert preferences over five key attributes: the amount of cargo delivered, the prioritization of aid ...
• Committed Versus Contingent Pricing Under Competition AI翻译

  摘要：Should capacitated firms set prices responsively to uncertain market conditions in a competitive environment? We study a duopoly selling differentiated substitutable products with fixed capacities under demand uncertainty, where firms can either commit to a fixed price ex ante, or elect to price contingently ex post, e.g., to charge high prices in booming markets, and low prices in slack markets. Interestingly, we analytically show that even for completely symmetric model primitives, asymmetri...
• Designing Efficient Infrastructural Investment and Asset Transfer Mechanisms in Humanitarian Supply Chains AI翻译

  摘要：We analyze the efficacy of different asset transfer mechanisms and provide policy recommendations for the design of humanitarian supply chains. As a part of their preparedness effort, humanitarian organizations often make decisions on resource investments ex ante because doing so allows for rapid response if an adverse event occurs. However, programs typically operate under funding constraints and donor earmarks with autonomous decision-making authority resting with the local entities, which m...
• Integrality in Stochastic Inventory Models AI翻译
  作者：Chen, Wei; Dawande, Milind; Janakiraman, Ganesh

  摘要：We study several finite-horizon, discrete-time, dynamic, stochastic inventory control models with integer demands: the newsvendor model, its multi-period extension, and a single-product, multi-echelon assembly model. Equivalent linear programs are formulated for the corresponding stochastic dynamic programs, and integrality results are derived based on the total unimodularity of the constraint matrices. Specifically, for all these models, starting with integer inventory levels, we show that th...
• Randomization Approaches for Network Revenue Management with Customer Choice Behavior AI翻译
  作者：Kunnumkal, Sumit

  摘要：In this study, we present new approximation methods for the network revenue management problem with customer choice behavior. Our methods are sampling-based and so can handle fairly general customer choice models. The starting point for our methods is a dynamic program that allows randomization. An attractive feature of this dynamic program is that the size of its action space is linear in the number of itineraries, as opposed to exponential. It turns out that this dynamic program has a struct...
