Simulation- Infotech in global economy
Chapter -Simulation – (InfoTech in a global economy) Simulation quality depends on simulation process
Three different simulation views
Standard:
*Verification - Validation - Do the outputs resemble observations of the target?
* Relies on the observability of reality - Must be able to compare simulation output to reality
*Standard view may suffer from under-determination -Multiple incompatible theories may result from the same data
Constructionist:
• Compares -What you observe in the real world with, - What you observe as simulation output
• Seems similar to Standard view, right? -Constructionists view all observations as constructions
• Evaluation is not possible - Even observations of reality lack the ability to pass validation
User community:
• Evaluation is carried out - Using the observations of the affected user community
• Not just based on prior knowledge
• Closer to “real” results
• Often, results are influenced by multiple related factors
