The Judging Process For Sym Bowl : A High School System Dynamics Modeling Competition, Wayne W. Wakeland Jul 1998

The Judging Process For Sym Bowl : A High School System Dynamics Modeling Competition, Wayne W. Wakeland

Wayne W. Wakeland

This “paper” describes the judging process used to determine the winners in SymBowl, a high school system dynamics modeling competition held in Portland, Oregon the past three years. SymBowl was created by Ed Gallaher, a medical researcher at the Portland VA Hospital and Associate Professor at Oregon Health Sciences University.
The judging criteria and judging process were developed by Wakeland, who has served as the judging coordinating for past three years, overseeing the process, compiling results, etc. Wakeland is an Adjunct Professor of System Science at Portland State University where he teaches graduate-level modeling and simulation classes.
For SymBowl 98, …

Blending Top-Down And Bottom-Up Approaches In Conceptual Design, Janis P. Terpenny, Bartholomew O. Nnaji, Jan Helge Bøhn Jan 1998

Blending Top-Down And Bottom-Up Approaches In Conceptual Design, Janis P. Terpenny, Bartholomew O. Nnaji, Jan Helge Bøhn

Janis P. Terpenny

In recent years, there has been significant attention given to improved methods and tools for engineering design. While advances for the latter stages of design have been impressive, this has not been the case for the early stages of design. In general, advances have provided for either a top-down or a bottom-up approach to design; ignoring the requirements for both abstraction and detail in a concurrently engineered development process. This paper describes an integrated conceptual modeling framework for a blended methodology. The utility and extensibility of this framework are considered in discussion and by way of examples.
