Analysis Of Scheduling For Low Cost Part Task Trainers, William Fellows Jul 1983

Analysis Of Scheduling For Low Cost Part Task Trainers, William Fellows

Retrospective Theses and Dissertations

This study develops a methodology for the analysis of Part Task Trainer (PTT) refresh scheduling used in conjunction with large simulators. A human performance model is defined through the development of descriptive equations and system random variables. PTT scheduling calculations are performed by employing a computer program simulation. The computer algorithm generates a set of random vectors to represent the learning characteristics of a sample group of individual trainees. The relationships between simulator scheduling time, PTT frequency training, and model variables are demonstrated to be user interactive. This will allow the PTT refresh scheduling program to be used as an …


Computer Simulation Of Cavity Filling During Injection Molding Process, Sumit Banerjee May 1983

Computer Simulation Of Cavity Filling During Injection Molding Process, Sumit Banerjee

Theses

A numerical technique is proposed for the simulation of cavity filling process during injection molding of glass-bead filled polypropylene. The mold cavity is of cylindrical shape. Marker And Cell (MAC) method is utilized for solving the transient flow phenomena, after a mathematical simulation of the flow model is carried out by using the relevant continuity and-momentum equations governing the system. The complexity of the equations involved, results in the simplifying assumption of incompressible and isothermal flow process. A computer program is written on the basis of finite-difference equations developed during the application of MAC method under the prevailing conditions.

Simulation Of Naval Student Flow Using Pipeline Management Model, Mary L. Sankey Jan 1983

Simulation Of Naval Student Flow Using Pipeline Management Model, Mary L. Sankey

Retrospective Theses and Dissertations

The U.S. Navy's training system is an extensive, complex system of interrelated and interacting components. This paper presents the results of several approaches to the problem of modeling this system and developing computer programs to simulate and analyze its operation. Two programs using special-purpose simulation languages, SLAM and GASP, are described briefly. The PMM inter-active system is described and analyzed in the greatest detail. Possible future utilization of this PMM system for experimentation and forecasting is also briefly discussed.
