2.2.5 Modelling and simulations** // Students must study and evaluate the social and ethical issues involved in the use of modelling and simulations. These may include:
 * Social and ethical issues** //

• reliability of predictions based on computer models, for example, weather, global warming

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

• security issues involved in military simulations

• social impact of reliance on simulations to examine issues of public policy

• responsibility of the designer for accuracy of assumptions underlying the model

• ethical considerations involved in deciding when to use models or simulations to ensure human safety.

// **Knowledge of technology** // In order to study and evaluate the social and ethical issues involved in the use of modelling and simulations, the student must have an understanding of related technological concepts. These may include: • key terms—model, 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.


 * Key Terms**

Model- Uses computers to create abstract models of objects, organisms, organizations, and processes.

Simulation- Creating a mathematical model of a real system, too see how the system works and by creating variables, make predictions about the system will change.

Feedback Loop- The casual path that leads from the initial generation of the feedback to the subsequent modification of the event.

GIGO- Garbage In, Garbage Out; when something is entered wrong then the results will be wrong all the time.

Illusion of Infallibility- When a person relies on a machine to give all the answers when what the computer is feeding out is wrong.

Faulty or Hidden Assumption- - No risk practice - Economy - Projections - Predictions - Visualisations - Repeated tests can be done - Tests may give a better variety of results to find the best one - People will not try - Economy misses out - Illusion of infallibity - Hidden assumptions - Faulty assumptions - Unable to have real assumption - People will act differently in real life
 * Faulty- Wrong information is not known and you think its fine but it goes all wrong in real life.
 * Hidden- When something is not seen or not found then it goes wrong.
 * Benefits**
 * Limitations**
