摘要：In revenue management research and practice, demand models are used that describe how demand for a seller's products depends on the decisions, such as prices, of that seller. Even in settings where the demand for a seller's products also depends on decisions of other sellers, the models often do not explicitly account for such decisions. It has been conjectured in the revenue management literature that such monopoly models may incorporate the effects of competition, because the parameter estim...

摘要：The 2007-2009 financial turmoil highlighted the need for more active management of credit portfolios. After measuring portfolio credit risk, an important step toward active risk management is to measure risk contributions of individual obligors to the overall risk of the portfolio. In practice, value-at-risk is often used as a risk measure for credit portfolios, and it can be decomposed into a sum of the risk contributions of individual obligors. Estimation of these risk contributions is compu...

摘要：A Searcher seeks to find a stationary Hider located at some point H (not necessarily a node) on a given network Q. The Searcher can move along the network from a given starting point at unit speed, but to actually find the Hider she must pass it while moving at a fixed slower speed (which may depend on the arc). In this bimodal search game, the payoff is the first time the Searcher passes the Hider while moving at her slow speed. This game models the search for a small or well hidden object (e...

摘要：We consider the problem of efficiently allocating the capacity of a number of service facilities (prone to congestion) to a set of users with private information regarding their willingness to pay for different combinations of throughput versus latency. Auction mechanisms can be used to schedule the service capacity of available facilities. However, the interdependency of users' valuations implies that simple uniform price adjustment processes (e.g., tatonnement) either fail to effectively cle...

摘要：Theoretical studies of process flexibility designs have mostly focused on expected sales. In this paper, we take a different approach by studying process flexibility designs from the worst-case point of view. To study the worst-case performances, we introduce the plant cover indices (PCIs), defined by bottlenecks in flexibility designs containing a fixed number of products. We prove that given a flexibility design, a general class of worst-case performance measures can be expressed as function...

摘要：In today's business environment, unpredictable economic and noneconomic forces can affect firms' operational costs and discount factors, as well as demand. In this paper, we incorporate these uncertainties into a single-product, periodic-review, finite-horizon stochastic inventory system by modeling operational costs, discount factors, and demands as stochastic processes that evolve over time. We study three stockout protocols and establish conditions under which (s, S) inventory policies are ...

摘要：This paper reports a new test of intransitive choice using individual measurements of regret-and similarity-based intransitive models of choice under uncertainty. Our test is tailor-made and uses subject-specific stimuli. Despite these features, we observed only a few intransitivities. A possible explanation for the poor predictive performance of intransitive choice models is that they only allow for interactions between acts. They exclude within-act interactions by retaining the assumption th...

摘要：This paper addresses two concerns with the state of the art in network revenue management with dependent demands. The first concern is that the basic attraction model (BAM), of which the multinomial logit (MNL) model is a special case, tends to overestimate demand recapture in practice. The second concern is that the choice-based deterministic linear program, currently in use to derive heuristics for the stochastic network revenue management problem, has an exponential number of variables. We ...

摘要：Queueing networks models typically assume that the arrival process is exogenous and unaffected by admission control, scheduling policies, etc. In many situations, however, users choose the time of their arrival strategically, taking delay and other metrics into account. In this paper, we develop a framework to study such strategic arrivals into queueing networks. We study the population game wherein users strategically choose when to arrive at a parallel queueing network and upon arrival, whic...

摘要：We examine the interplay between two important decisions that impact environmental performance in a production setting: inspections performed by a regulator and noncompliance disclosure by a production firm. To preempt the penalty that will be levied once a compliance violation is discovered in an inspection, the firm dynamically decides whether it should disclose a random occurrence of noncompliance. Anticipating this, the regulator determines inspection frequency and penalty amounts to minim...
