In diagnostic services, agents typically need to weigh the benefit of running an additional test and improving the accuracy of diagnosis against the cost of delaying the provision of services to others. Our paper analyzes how to dynamically manage this accuracy/congestion trade-off. To that end,...

We consider a finite-state, finite-action, infinite-horizon, discounted reward Markov decision process and study the bias and variance in the value function estimates that result from empirical estimates of the model parameters. We provide closed-form approximations for the bias and variance,...

Deciding who should receive a mail-order catalog is among the most important decisions that mail-order-catalog firms must address. In practice, the current approach to the problem is invariably myopic: firms send catalogs to customers who they think are most likely to order from that catalog. In...

Two recent papers on managing new product diffusion decisions under production constraints reach somewhat contradictory conclusions. Ho et al. (Ho, T.-H., S. Savin, C. Terwiesch. 2002. Managing demand and sales dynamics in new product diffusion under supply constraint. <i>Management Sci.</i> <b>48</b>(2)...

We consider the problem of allocating a single server to a system of queues with Poisson arrivals. Each queue represents a class of jobs and possesses a holding cost rate, general service distribution, and general set-up time distribution. The objective is to minimize the expected holding cost...

We consider the interrelated problems of (1) quoting a due date to each customer arriving to a production system modeled as a single-server queue and (2) sequencing customer orders once they are in the system. We allow several different classes of customers, each with different preferences for...

We consider a two-location production/inventory model where each location makes production decisions and is subject to uncertain capacity. Each location optimizes its own profits. Transshipment (at a cost) is allowed from one location to another. We focus on the question of whether one can...

We address an assembly problem, motivated by flat panel display manufacturing, where the quality (or performance) of the final product depends upon characteristics of the components to be assembled, which are not constant from component to component. We analyze the tradeoff between the increase...

We consider the problem of quoting customer lead times in a manufacturing environment under a variety of modeling assumptions. First, we examine the case where capacity is infinite. For this case, we derive a closed-form expression for the optimal lead time quote. Second, we consider the case...

We model a CONWIP (CONstant Work-in-Process) production line with deterministic processing times and exponential failure and repair times as a closed queueing network. We derive an approximation for the mean and variance of the output during a specified interval and give computable conditions...
