In the extant supply-risk management literature, most research assumes the manufacturer is as knowledgeable about supply disruption risk as its suppliers. In practice, however, a supplier often has better information about its likelihood of experiencing a disruption than the manufacturer it...

This dissertation discusses substitution effects on retail pricing problems. In the presence of substitutable products, the inventory levels and prices of different products interact in complicated ways and, therefore, insights developed in the context of single-product pricing problems do not...

Companies in a broad range of industries and economies rely heavily on external sources to finance their operations. But, external financing could be expensive and/or difficult to obtain due to imperfections in real capital markets. I focus on cash-constrained manufacturers that rely on external...

The first essay considers a service center with two stations in accordance with independent Poisson processes. Service times at either station follow the same general distribution, are independent of each other and are independent of the arrival process. The system is charged station-dependent...

This dissertation examines global groups at work through an intensive study of cross-national student teams and case studies of exemplar companies that work across boundaries. We consider the role of transactive memory systems (TMS) as a way to create effective team processes. A TMS is a...

Graphical user interfaces (GUIs) are being increasingly used in the classroom to provide users of computer simulations with a friendly and visual approach to specifying all input parameters and increased configuration flexibility. In this study, the authors first describe a number of software...

In this paper, we consider a multiple-stage tandem production/inventory system producing a single product. Processing time at each stage is assumed to have a general stationary processing time distribution. The cost of holding work-in-process (WIP) inventory is different at each stage....

We consider a make-to-stock production/inventory system consisting of a single deteriorating machine which produces a single item. We formulate the integrated decisions of maintenance and production using a Markov Decision Process. The optimal dynamic policy is shown to have a rather complex...

We consider M transmitting stations sending packets to a single receiver over a slotted time-multiplexed link. For each phase consisting of T consecutive slots, the receiver dynamically allocates these slots among the M transmitters. Our objective is to characterize policies that minimize the...

A simple, eclectic approach for solving discrete alternative multiple criteria decision problems is presented. It is based on the concept of the level of aspiration, and draws on ideas of various researchers. It assumes that the user has a set of alternatives with each alternative having a score...
