• Mixed-model assembly lines with variable takt and open stations AI翻译

  摘要：Industry trends such as product customization, radical innovation, and local production accelerate the adoption of mixed-model assembly lines (MMALs) that can cope with a widening gap between model processing times and true build to order capabilitiy. The existing high work content deviations on such assembly lines stress production planning, especially the assembly line sequencing. Most manufacturers set the launching rate for all assembly line products to a fixed launching rate resulting in ...
• A survey of stochastic inventory models with fixed costs: Optimality of (s, S) and (s, S)-type policies-Continuous-time case AI翻译

  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 lo...
• Games of supplier encroachment channel selection and e-tailer's information sharing AI翻译

  摘要：We consider an e-tailer's upstream supplier who wants to encroach into retailing to earn additional revenue. The supplier needs to decide whether or not to enter the retail market by either selling to consumers on the e-tailer's platform by paying commission fees (agency encroachment) or opening an independent online/offline retail store (direct encroachment). The e-tailer has private demand information and decides whether or not to share it with the supplier. Two leadership scenarios-the supp...
• How incumbents beat disruption? Evidence from hotel responses to home sharing AI翻译

  摘要：As the sharing economy continues to disrupt incumbent services, whether and how incumbents respond to the competition remains largely unknown. We investigate how incumbents can utilize management responses-a managerial intervention to guest reviews-to exploit performance improvement opportunities in guest reviews and sustain competitive advantage facing increased competition from home sharing. Our method integrates quasi-experiments, topic modeling, and deep learning techniques to not only est...
• Sourcing and pricing decisions under upstream competition with a financially distressed supplier, endogenous bankruptcy risk, and a backup supply option AI翻译

  摘要：To maintain future supplier competition, manufacturers may support financially distressed suppliers by sourcing from them, even if they are less efficient than competitors, and by procuring larger quantities from them at higher prices. We analyze these strategies in a model in which a manufacturer decides for one of two available suppliers, supplier bankruptcy risk is endogenous, and financial distress can lead to internal or external reorganization. Following bankruptcy, the remaining supplie...
• Gaining by ceding - bounded wholesale pricing for information sharing in a supply chain AI翻译

  摘要：The extant research on supply chain information sharing under wholesale pricing often assumes a model where the manufacturer can unilaterally set any wholesale price, and the retailer decides retail quantity or price while taking the wholesale price as given. Whereas this model may actually reflect the relative market power in some situations, its implementation misses out on certain win-win opportunities that could arise from information sharing. We propose a new wholesale pricing mechanism t...
• Peer-to-peer sharing platforms with quality differentiation: Manufacturer's strategic decision under sharing economy AI翻译

  摘要：As peer-to-peer sharing platforms emerge in the downstream market, upstream product manufacturers may build their exclusive sharing platform, seeking benefits from the sharing market. To study the profit and welfare implications of the emergence of sharing economy and manufacturer's platform-building strategy, we employ a vertically differentiated duopoly setting and consider three scenarios: no-sharing benchmark, a single third-party platform emerged, and manufacturer-built platform co-existi...
• Competitive multiproduct contracting under multinomial logit demand AI翻译
  作者：Shao, Lusheng
  作者单位：University of Melbourne
  摘要：Despite the prevalence of multiproduct firms in many industries, the supply chain contracting literature has predominantly focused on problems where an upstream player offers only one product. This paper studies multiproduct contract design for competing manufacturers each with several products to sell via a common retailer. We consider two contracting schemes under multinomial logit demand (MNL): individual contracting, in which the manufacturers set a wholesale price for each of their produc...
• COVID-19: A multiwave SIR-based model for learning waves AI翻译

  摘要：One of the greatest challenges of the COVID-19 pandemic has been the way evolving regulation, information, and sentiment have driven waves of the disease. Traditional epidemiology models, such as the SIR model, are not equipped to handle these behavioral-based changes. We propose a novel multiwave susceptible-infected-recovered (SIR) model, which can detect and model the waves of the disease. We bring together the SIR model's compartmental structure with a change-point detection martingale pro...
• Risk-sensitive Markov decision processes with long-run CVaR criterion AI翻译
  作者：Xia, Li; Zhang, Luyao; Glynn, Peter W.
  作者单位：Sun Yat Sen University; Stanford University
  摘要：CVaR (Conditional value at risk) is a risk metric widely used in finance. However, dynamically optimizing CVaR is difficult, because it is not a standard Markov decision process (MDP) and the principle of dynamic programming fails. In this paper, we study the infinite-horizon discrete-time MDP with a long-run CVaR criterion, from the view of sensitivity-based optimization. By introducing a pseudo-CVaR metric, we reformulate the problem as a bilevel MDP model and derive a CVaR difference formul...
