Interesting question when you are more a biologist than a mathematician (too many complicated equations!!!) And as most of your team members were biologists/biochemists, we tried to explain the model easily for everyone.

Definitions:

A model is a symbolic representation of an object’s or phenomenon’s aspects in the real world.

“All models are false. Some are useful.” Georges Box

Modeling is the process that allows the development of a model. It’s taking into account:

• The phenomenon to represent
• A specific formal system (equation, diagram..)
• Objectives (what we want to do with the model)
• Data (for variables) and knowledge (relation between variables) available or accessible by experimentation or observation

The tasks to obtain the model depend on the biological situation and the formal system chosen. Nevertheless, it must:

• have a formalization work, which is the model writing
• Manipulate the model in the formal system to make it "usable" and to study its properties
• Objectives (what we want to do with the model)
• Establish relationships with other representations (computer program, graph function)
• Interpret and compare different representations obtained in the formal world with the biological reality (often that reality is seen through experimental data
)
