On the Introduction of an Agile, Temporary Workforce into a Tandem Queueing System
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2005-10)
We consider a two-station tandem queueing system where customers arrive according to a Poisson process and must receive service at both stations before leaving the system. Neither queue is equipped with dedicated servers. ...
An Incomplete Cholesky Factorization for Dense Symmetric Positive Definite Matrices
(Kluwer Academic Publishers; Swets & Zeitlinger ; Springer Science+Business Media, 2000-09)
In this paper, we study the use of an incomplete Cholesky factorization (ICF) as a preconditioner for solving dense symmetric positive definite linear systems. This method is suitable for situations where matrices cannot ...
An Integrated Model of a Fixture-Workpiece System for Surface Quality Prediction
(Springer-Verlag London Limited, 2001-05)
A Hit-and-Run approach for generating scale invariant Small World networks
(Wiley Subscription Services, Inc., A Wiley Company, 2009-01)
Hit-and-Run is a well-known class of Markov chain algorithms for sampling from essentially arbitrary distributions over bounded regions of the Euclidean space. We present a class of Small World network models constructed ...
Lean job design and musculoskeletal disorder risk: A two plant comparison
(Wiley Subscription Services, Inc., A Wiley Company, 2009-07)
This study examined the relationship between lean job design and work-related musculoskeletal disorder (WMSD) risk factors. Repetition, force, and posture were assessed for a sample of 56 production jobs across departments ...
Prolonged median sensory latency as a predictor of future carpal tunnel syndrome
(John Wiley & Sons, Inc., 2001-11)
The purpose of the study was to determine whether abnormal median sensory nerve conduction among asymptomatic workers was predictive of future symptoms suggestive of carpal tunnel syndrome (CTS). This was a prospective ...
On simulating human reach motions for ergonomics analyses
(Wiley Subscription Services, Inc., A Wiley Company, 2002)
Many existing job analysis tools for ergonomics have concentrated on the potential adverse effects of force, posture, and repetition, as these appear to be traditionally recognized risk factors in the workplace. Recent ...
A Reach and Bound algorithm for acyclic dynamic-programming networks
(Wiley Subscription Services, Inc., A Wiley Company, 2008-08)
Node pruning is a commonly used technique for solution acceleration in a dynamic-programming network. In pruning, nodes are adaptively removed from the dynamic programming network when they are determined not to lie on an ...
Condition number complexity of an elementary algorithm for computing a reliable solution of a conic linear system
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-09)
A conic linear system is a system of the form¶¶(FP d )Ax = b ¶ x ∈ C X ,¶¶where A:X ? Y is a linear operator between n - and m -dimensional linear spaces X and Y , b ∈ Y , and C X ⊂X is a closed convex cone. The data for ...
Rank-Cluster-and-Prune: An algorithm for generating clusters in complex set partitioning problems
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
Clustering problems are often difficult to solve due to nonlinear cost functions and complicating constraints. Set partitioning formulations can help overcome these challenges, but at the cost of a very large number of ...
