2.2.5 Modelling and Simulations

Paper One and Two may require you to evaluate the social and ethical issues involved in the use of Modelling and Simulation software, you should have an understanding of the following related technological concepts:
 

Read all of this article - THIS IS IMPORTANT!

Social and Ethical Issues:

• What is the reliability of predictions based on computer models, for example, weather, global warming?

• What are the economic effects of the use of models to design and test new products?

• What are the security issues involved in military simulations?

• What is the social impact of reliance on simulations to examine issues of public policy?

• What is the responsibility of the designer for accuracy of assumptions underlying the model?

• What are the ethical considerations involved in deciding when to use models or simulations to ensure human safety?

Knowledge of Technology:

• computer model

• computer simulation

• feedback loop

• faulty or hidden assumptions

• extent and effect of the simplification of reality

• extent to which the phenomenon being modelled is understood

• processing power needed to create complex models

• visualization of information

• correspondence of the model with reality.

	Do you understand these issues and terms?  If you don't then do some research - find out what it ALL means.

Developing new medicines is usually a long and costly process. Now, methods are being developed at Norwegian University of Science and Technology – that allow some of the testing required in drug development that normally take years to complete to be done in just a fraction of the time. With the help of mathematical calculations and computer simulations, researchers can quickly find out if a substance has the qualities and characteristics of an effective drug before it is tested in the real world.

1. A well constructed drug testing simulation would include feedback loops. Define feedback.

2. Distinguish between a computer model and simulation.

3. Explain why a drug company might be concerned about using drug simulations.

4. Discuss two social and/or ethical issues that arise from the use of computer models and simulations to test new drugs.
