SD Work Related to NASA

Colleagues: One of my students is interested in any system dynamics work that has been done in the area of budgeting and management at NASA (the National Aeronautics and Space Administration - USA). If any of you know of anything, please e-mail me. Thanks. Mike Radzicki ^~^~^~^~^~^~^~^~^~^~^~^~^~^~^...

Simulation of road accident

Hi Arif: One stream-of-consciousness response that comes to mind upon reading your problem statement below is that the structure of a simple traffic system in which one driver is following another (and even better, if several drivers are following one another in line) is similar (at least at first p...

IS-LM model or a like macroeconomic models

Branko: Nathan Forresters dissertation titled: "A Dynamic Synthesis of Basic Macroeconomic Theory: Implications for Stabilization Policy Analysis" (available from MIT) presents the IS-LM model (extended through aggregate supply and demand) via system dynamics. Also, I have created a series...
