摘要：Our research question is motivated by a real problem faced by an existing demand aggregator. The aggregator represents multiple advertisers, each of whom signs one of two types of contracts with the aggregator for bidding on an RTB (real-time bidding) platform. A quality contract occurs on a cost-per-impression (CPM, i.e., cost per thousand impressions) basis. The advertiser is promised a minimum number of impressions and pays a CPM that is a function of the targeting quality as measured by th...

摘要：In this paper, we examine a data-driven optimization approach to making optimal decisions as evaluated by a trained random forest, where these decisions can be constrained by an arbitrary polyhedral set. We model this optimization problem as a mixed-integer linear program. We show this model can be solved to optimality efficiently using pareto-optimal Benders cuts for ensembles containing a modest number of trees. We consider a random forest approximation that consists of sampling a subset of ...

摘要：Testing for COVID-19 is a key intervention that supports tracking and isolation to prevent further infections. However, diagnostic tests are a scarce and finite resource, so abundance in one country can quickly lead to shortages in others, creating a competitive landscape. Countries experience peaks in infections at different times, meaning that the need for diagnostic tests also peaks at different moments. This phase lag implies opportunities for a more collaborative approach, although countr...

摘要：At the onset of the COVID-19 pandemic, hospitals were in dire need of data-driven analytics to provide support for critical, expensive, and complex decisions. Yet, the majority of analytics being developed were targeted at state- and national-level policy decisions, with little availability of actionable information to support tactical and operational decision-making and execution at the hospital level. To fill this gap, we developed a multi-method framework leveraging a parsimonious design ph...

摘要：Product evaluation is an essential business process, and digital innovation has made it possible for companies to immediately process available information. We develop a model where a company continuously assesses information that follows a doubly stochastic Poisson process with a mean-reverting and stochastic intensity. Accordingly, the company faces a two-dimensional optimal stopping problem in which the company continues to evaluate the product if and only if the product reputation and info...

摘要：Sharing economy platforms are pressed to rapidly grow user bases at the early stage by aggressively targeting potential users through competitive actions. Due to the volatile nature of the sharing economy and its disruption to industry norms, these platforms encounter legitimacy challenges that impede user base growth. This paper integrates competitive repertoire and institutional legitimacy theories to develop a research model that explains early-stage user base development in the sharing eco...

摘要：In 2021, access to clean drinking water was still a luxury for millions of people worldwide. Building new water projects, such as handpumps and small piped systems, is the primary operational response by many nongovernmental organizations (NGOs) to bring people their first access to clean water in rural areas of developing countries. Based on knowledge gained from our collaboration with a local NGO and an international NGO and field research in Ethiopia, our research studies where to build new...

摘要：Nowadays, a transportation station has the possibility to provide its potential passengers with information regarding the arrival times of the successively arriving facilities, the congestion in the station and the space availability of future facilities. Such information influences the behavior of the passengers who think strategically and consequently the throughput and the welfare that are generated by the system. In the present work, we consider a general model of a transportation station ...

摘要：Traditionally, manufacturer encroachment is investigated under an integrated organizational structure where online business decisions are made at the whole firm level. However, with the establishment of a specific e-commerce division, the manufacturer has the flexibility to delegate the decision-making of the online business to its e-commerce division to maximize the online revenue under a decentralized structure. We study manufacturer encroachment in a supply chain, where a manufacturer sells...

摘要：What makes a technology valuable? Characterizing the value as the degree of impact on subsequent technology development and focusing on the rareness as a composite measure of novelty and conventionality representing the relative position of a technology in a technology space, we advance a theory on the relationship between the rareness and value of a technology as well as the moderating role of search basis in shaping the relationship. We build our theory exploiting the fundamental trade-off b...
