This paper describes models that estimate the cost and time of sheet metal punching when nesting (batching) orders. These models help decision-makers plan production and evaluate the impact of changing the nesting policy. ...

This report describes an integrated, distributed fault management (IDFM) system for communication networks. The architecture is based on a distributed intelligent agent paradigm, with probabilistic networks as the framework ...

This paper addresses the gradient estimation of transfer linescomprising two machines separated by a buffer of finite capacity. A continuous flow model is considered, where machines are subject tooperation-dependent failures, ...

The motivation of this thesis is to perform research in the arena of discrete tradeoff analysis. There are two fundamental aspects to the problem domain to be be studied. The first involves modeling the manner in which the ...

As part of the ongoing research in operations research, new reschedulingalgorithms are constantly being invented. Until now, however, the testingand analysis of these algorithms was unstandardized. The method forcomparing ...

In this paper, we address the problem of propagating data updates to alarge number of mobile clients. Typically, mobile clients operateautonomously, i.e., disconnected from data servers, for prolongedperiods of time relying ...

It is observed that an algorithm proposed in the 1980s for thesolution of nonconvex constrained optimization problems is in fact aprimal-dual logarithmic barrier interior-point method closely related tomethods under current ...

The Black & Decker factory in Easton, Maryland, uses parallel, off-line assembly lines to produce multiple models in small, infrequent production runs. The University of Maryland and Black & Decker have implemented an ...

We derive a lower bound for the staffing levels required to meet a projected load in a retail service facility. We model the queueing system as a Markovian process with non-homogeneous Poisson arrivals. Motivated by an ...

This thesis proposes an architecture for wireless services in telemedicine.The scenario visualized is of an ambulance carrying a traumapatient and sending medical data (video, ultrasound, ECG) to itscorresponding hospital. ...
