Evaluating Sheet Metal Nesting Decisions
(1998)
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. ...
Gradient Estimation of Two-Stage Continuous Transfer Lines Subject to Operation-Dependent Failures
(1998)
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, ...
A User Interface for Discrete Optimization-Based Tradeoff Analysis
(1998)
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 ...
A System to Test Rescheduling Algorithms
(1998)
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 ...
A Computationally Efficient Feasible Sequential Quadratic Programming Algorithm
(1998)
The role of optimization in both engineering analysis and designis continually expanding. As such, faster and more powerful optimization algorithms are in constant demand. In this dissertation, motivated by problems from ...
A Primal-Dual Interior-Point Method for Nonconvex Optimization with Multiple Logarithmic Barrier Parameters and with Strong Convergence Properties
(1998)
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 ...
A Lower Bounding Result for the Optimal Policy in an Adaptive Staffing Problem
(1998)
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 ...
Wireless Services for Telemedicine via AIN
(1998)
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. ...
A Computationally Efficient Feasible Sequential Quadratic Programming Algorithm
(1998)
A Sequential Quadratic Programming (SQP) algorithm generatingfeasible iterates is described and analyzed.What distinguishes this algorithm from previous feasible SQP algorithms proposed by various authors is a drastic ...
