Commonly models are generated to have a realistic and much more simplified illustration of something mentioned above. Models are highly used in architecture. It allows investors to select from a range of models according to what suits them the best, which is definitely better than investing large sums of money and then determining that the product does not fit the needs.

Good examples of models can be seen in medicine, where models of several drugs are created on computers, and specific functional groups on the molecules of specific drugs can be altered to determine a desired effect. The main issue with models, as mentioned numerously above is that they can be wrong. This creates a problem because, how would a person disapprove of a model when it works in some cases and not in others, since it is difficult to tell the difference. Models are supposed to make us understand things better, even to give us an overall view of things, but then again, models are not 100% accurate.
