Computational behavior of a feasible direction method for linear programming
(Elsevier, 1989-06-15)
We discuss a finite method of feasible directions for linear programs. The method begins with a BFS (basic feasible solution) and constructs a profitable direction by combining the updated columns of several nonbasic ...
Data-Driven Three-Phase Fundamental Diagram for Traffic Modeling
(2016-05-30)
Macroscopic traffic flow models are widely used to estimate traffic status on a freeway, and the fundamental diagram (FD), that establishes a relationship between density and flux, is essential for these models to be ...
Supplier dependence and innovation: a contingency model of suppliers' innovative activities
(Elsevier, 1990-09)
The management of innovation is a complex task and the management of suppliers' innovative activities is especially so because it involves managing technological factors across the traditional boundaries of the firm. This ...
A linear programming approach to constrained nonstationary infinite-horizon Markov decision processes
(2013-03-06)
Constrained Markov decision processes (MDPs) are MDPs optimizing an objective function while satisfying additional constraints. We study a class of infinite-horizon constrained MDPs with nonstationary problem data, finite ...
An evaluation of the effect of a training program on worker lifting postures
(Elsevier, 1986-12)
Though worker training is often chosen as a means to reduce the risk of low back pain if involved in lifting activities, the effect on a worker's lifting posture is rarely reported. This paper describes a video analysis ...
Estimating the throughput of an exponential CONWIP assembly system
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1993-03)
We consider a production system consisting of several fabrication lines feeding an assembly station where both fabrication and assembly lines consist of multiple machine exponential workstations and the CONWIP (CONstant ...
Evaluation of a new work seat for industrial sewing operations : Results of three field studies
(Elsevier, 1989-03)
A newly developed work seat for industrial sewing operations was compared with a traditional sewing work seat to evaluate the effectiveness of design features. The new seat was designed with special seat-pan and backrest ...
Examination of the effect of tool mass and work postures on perceived exertion for a screw driving task
(Elsevier, 1993-08)
Eighteen subjects with industrial work experience drove screws into perforated sheet metal at three vertical (64, 114 and 165 cm) locations with a pistol-shaped tool, and at two horizontal (13 and 63 cm) work locations ...
A biomechanical evaluation of five lifting techniques
(Elsevier, 1986-03)
Five lifting methods which cover the range of techniques recommended by various back schools have been biomechanically analysed with a static sagittal-plane computer model. The analysis was performed with two load-types ...
