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：Uncertainties involved in decision making often impose challenges to our ability of modeling and analyzing the reality. The purpose of this study is to demonstrate how one can go beyond the conventional optimization thinking, via taking a stochastic viewpoint, to push the boundaries of the analysis. We review the basic notions of stochastic orders and stochastic functions, with which the conventional (deterministic) way of modeling can be generalized. Based on the orders among distribution fun...

摘要：Parallel imports of gray products across markets are a worldwide concern for manufacturers. Extant research has focused on parallel imports of regular goods that do not provide status value. In this paper, we investigate parallel imports of conspicuously consumed status goods. We consider a manufacturer who directly sells a status product to consumers in two markets that value the product differently and a gray marketer that can import the product across markets. Our analysis shows that, thoug...

摘要：A common feature to electricity markets with derivative contracts is that the traded contracts are almost only futures and that they are traded multiple times the overall electricity demand. To understand why this occurs in practice, we study the efficiency of risk aligning in the competitive energy industry through derivative contract trading. We derive conditions that need to hold for a contract to provide the most efficient risk aligning, among all possible derivative contracts imaginable. ...

摘要：Two field case studies uncover information discounting in supply chains, which manifests in the form of schedule padding and order inflation. Buyers often exaggerate the urgency and quantity of their needs (crying wolf). However, both buyers and suppliers eliminate old, inflated orders from their behavioral ordering/supply system implicitly (knowing wink) even though they exist in the hyper-rational ordering system represented by the ERP system. This behavior results in (and from) low credibil...

摘要：Textile waste is one of the most pollutant items globally, being strongly affected by fast fashion (FF) products. Public pressure has made many FF firms voluntarily collect a small fraction of their preowned items and export them to developing countries for reuse. However, some developing countries are launching import bans on second-hand clothes. In addition, FF firms may soon be forced by extended producer responsibility legislation to collect more preowned items for reuse and recycling. To ...

摘要：The number and impact of open source projects is increasing. We examine the impact of competition from open source software (OSS) on proprietary software providers by analyzing three cases: (i) proprietary software as a monopoly, (ii) mixed duopoly competition between proprietary software provider and OSS, and (i) duopoly competition between two proprietary software providers. We use an analytical model to capture two important features of OSS: (i) its zero licensing price and (ii) its lower u...

摘要：Accessibility of electric vehicle (EV) charging stations is an important factor for adoption of EV, which is an effective green technology for reducing carbon emissions. Recognizing this, many governments are contemplating ideas for achieving EV adoption targets, such as constructing extra EV charging stations directly or offering subsidies to entice automakers to construct more EV charging stations. To achieve these targets, governments need to coordinate with automakers to ensure that the to...

摘要：We consider a general joint pricing and inventory management model with delayed differentiation, in which a firm serves a market with multiple products made from a generic one. The firm holds inventory for the generic product which is produced using multiple resources. Moreover, the market size, the attractiveness of each product, the firm's productivity, and the procurement cost of each resource all evolve over the planning horizon driven by an exogenous Markov process. Comparative statics an...

摘要：The role of artificial intelligence (AI) in augmenting healthcare is expected to grow substantially in future decades. Current research in medical AI focuses on developing, validating, and implementing point-level AI applications in an ad hoc manner. To harness the full power of AI to improve the patient experience and outcomes at a societal scale, however, requires a gestalt shift-with a systematic understanding of AI in the context of healthcare-and so results in its widespread adoption. Thi...
