The relationship of isometric strength to peak dynamic hand forces during submaximal weight lifting
(Elsevier, 1992-01)
Reports have indicated that approximately one third of the US workforce is presently required to exert significant strength as part of their jobs. In addressing the prevention of these types of injuries, the assessment of ...
Modeling and analysis of multi‐stage transfer lines with unreliable machines and finite buffers
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-01)
This paper models and analyzes multi‐stage transfer lines with unreliable machines and finite buffers. The machines have exponential operation, failure, and repair processes. First, a mixed vector–scalar Markov process ...
A Finite Algorithm for Solving Infinite Dimensional Optimization Problems
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-01)
We consider the general optimization problem ( P ) of selecting a continuous function x over a σ-compact Hausdorff space T to a metric space A , from a feasible region X of such functions, so as to minimize a functional c ...
A novel modeling approach for express package carrier planning
(Wiley Subscription Services, Inc., A Wiley Company, 2008-10)
Express package carrier networks have large numbers of heavily-interconnected and tightly-constrained resources, making the planning process difficult. A decision made in one area of the network can impact virtually any ...
An analysis of experts' ratings of ergonomic stress
(Elsevier, 1988-08)
Experts in the field of industrial ergonomics are frequently called upon to visit workplaces in order to evaluate and rate ergonomic stressors which may cause fatigue, discomfort, or injury. The objective of this study was ...
A simple proof of a primal affine scaling method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
In this paper, we present a simpler proof of the result of Tsuchiya and Muramatsu on the convergence of the primal affine scaling method. We show that the primal sequence generated by the method converges to the interior ...
Stochastic scheduling of parallel queues with set-up costs
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1995-12)
We consider the problem of allocating a single server to a system of queues with Poisson arrivals. Each queue represents a class of jobs and possesses a holding cost rate, general service distribution, and a set-up cost. ...
Call Center Staffing with Simulation and Cutting Plane Methods
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-03)
We present an iterative cutting plane method for minimizing staffing costs in a service system subject to satisfying acceptable service level requirements over multiple time periods. We assume that the service level cannot ...
The primal power affine scaling method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
In this paper, we present a variant of the primal affine scaling method, which we call the primal power affine scaling method. This method is defined by choosing a real r >0.5, and is similar to the power barrier variant ...
Shoulder postural fatigue and discomfort : A preliminary finding of no relationship with isometric strength capability in a light-weight manual assembly task
(Elsevier, 1990-03)
Does greater strength capacity in the shoulder-complex afford increased protection against regionalized fatigue and discomfort induced by sustained awkward arm postures in light-weight manual assembly environments? This ...
