Computer modeling

Modeling & Simulation

A computer model is an abstract mathematic representations of a real-world event, system, behavior, or natural phenomenon. A computer model is designed to behave just like the real-life system. The more accurate the model, the closer it matches real-life.  

A computer model is a translation of objects or phenomena from the real world into mathematical equations.

Thanks to https://www.igcseict.info for the content below. A model might be used:

• To test a system without having to create the system for real (Building real-life systems can be expensive, and take a long time)
• To predict what might happen to a system in the future (An accurate model allows us to go forward in virtual time to see what the system will be doing in the future)
• To train people to use a system without putting them at risk (Learning to fly an airplane is very difficult and mistake will be made. In a real plane mistakes could be fatal!)
• To investigate a system in great detail (A model of a system can be zoomed in/out or rotated. Time can be stopped, rewound, etc.)

Constructing a model

Model Construction Principle: Problems must be designed to allow for the creation of a model dealing with:

• Elements
• Relationships and operations between these elements
• Patterns and rules governing these relationships

Do I have a model?

1. I have identified important features of whatever events I hope to represent.
2. I identified rules that control those features and their relationships.
3. I have expressed those rules with math.
4. I have adjusted for how likely each factor is.

Standards

• Define the term computer modelling.

Give an expected result of an upcoming action or event.

Observe, study, or make a detailed and systematic examination, in order to establish facts and reach new conclusions.

Give the precise meaning of a word, phrase, concept or physical quantity.
