Analytical Methodology For Atm Control Panel Design, Donald C. Johnson Dec 1991

Analytical Methodology For Atm Control Panel Design, Donald C. Johnson

Theses

This thesis presents a methodology for control panel design and layout along with a case study of an automated teller machine (ATM). A predictive model of human endurance and fatigue is developed from anthropometric, biomechanical and kinematics research. The layout problem is formulated to assign controls to locations to minimize the fatigue imposed on an operator performing a known set of tasks. A family of optimal and near-optimal layouts are found using conventional algorithms. The final hardware design refinements are suggested by human factors concerns. Ergonomic guidelines are also proposed for software aspects of the design. The methods and guidelines …

A Modified M/G/1/N System And Its Application, Bernice Annette Figueroa

Theses

We study a single server queueing system with finite buffer, Poisson arrivals and exceptional service requirements for the first customer in each busy period. The system is studied as a Markov Chain and the limiting probability distributions are obtained. The explicit form sorution for the queue length distribution, blocking probability, waiting time distribution as well as the busy period are derived through the Laplace-Stieltjes transform method. These results are then applied to a tandem system with a finite buffer in front of the first station and no intermediate buffer between the two stations. Finally, similar results are obtained for the …
