Stochastic TransportationInventory Network Design Problem
(200201)In this paper, we study the stochastic transportationinventory network design problem involving one supplier and multiple retailers. Each retailer faces some uncertain demand. Due to this uncertainty, some amount of safety ... 
Solving symmetric indefinite systems in an interiorpoint method for second order cone programming
(200201)Many optimization problems can be formulated as second order cone programming (SOCP) problems. Theoretical results show that applying interiorpoint method (IPM) to SOCP has global polynomial convergence. However, various ... 
Design and Optimization of Complex Systems
(200201)Truely optimal solutions to system design can only be obtained if the entire system is considered. In this research we consider design of commercial aircraft, but we expand the system to include a family of planes. A ... 
Finite Element Output Bounds for a Stabilized Discretization of Incompressible Stokes Flow
(200201)We introduce a new method for computing a posteriori bounds on engineering outputs from finite element discretizations of the incompressible Stokes equations. The method results from recasting the output problem as a ... 
Pup Matching: Model Formulations and Solution Approaches
(200201)We model Pup Matching, the logistics problem of matching or pairing semitrailers known as pups to cabs able to tow one or two pups simultaneously, as an NPcomplete version of the Network Loading Problem (NLP). We examine ... 
Reliable RealTime Solution of Parametrized Elliptic Partial Differential Equations: Application to Elasticity
(200201)The optimization, control, and characterization of engineering components or systems require fast, repeated, and accurate evaluation of a partialdifferentialequationinduced inputoutput relationship. We present a technique ... 
Acceleration of Gas BubbleFree Surface Interaction Computation Using Basis Preconditioners
(200201)The computation of gas bubblefree surface interaction entails a timestepping algorithm whereby a linear system is solved at each timeiteration. In our investigation, the linear systems are derived from a desingularized ... 
Bounds on Linear PDEs via Semidefinite Optimization
(200201)Using recent progress on moment problems, and their connections with semidefinite optimization, we present in this paper a new methodology based on semidefinite optimization, to obtain a hierarchy of upper and lower bounds ... 
Design and Analysis of Printed Circuit Boards Using FDTD Method for The 20H Rule
(200201)With the increasing demand of higher operating frequencies for electronic circuits, the printed circuit board designers face more electromagnetic radiation problems than ever. Some “rulesofthumb” are employed to help the ... 
RealTime Optimal Parametric Design of a Simple InfiltrationEvaporation Model Using the AssessPredictOptimize (APO) Strategy
(200301)Optimal parametric design of a system must be able to respond quickly to short term needs as well as long term conditions. To this end, we present an AssessPredictOptimize (APO) strategy which allows for easy modification ... 
MultiDisciplinary Analysis in Morphing Airfoils
(200301)Fully morphing wings allow the active change of the wing surface contours/wing configuration in flight enabling the optimum wing design for various flight regimes. These wing shape deformations are obtained by using smart ... 
Structural Topology Optimization Using a Genetic Algorithm and a Morphological Representation of Geometry
(200301)This paper describes an intuitive way of defining geometry design variables for solving structural topology optimization problems using a genetic algorithm (GA). The geometry representation scheme works by defining a ...
