What are the limitations of a mathematical model?

Mathematical models have limitations that can affect their accuracy and usefulness.

Mathematical models are used to represent real-world phenomena using mathematical equations and formulas. However, these models have limitations that can affect their accuracy and usefulness. One limitation is that mathematical models are simplifications of reality and may not capture all the complexities of the system being modelled. For example, a model of a population growth may not take into account factors such as migration, disease, or natural disasters that can affect the population. To understand more about how these models apply to practical scenarios, see Real World Applications.

Another limitation of mathematical models is that they rely on assumptions that may not always hold true. For example, a model of a chemical reaction may assume that the reaction is taking place in a closed system, but in reality, the reaction may be affected by external factors such as temperature or pressure. It is crucial to recognise how these assumptions influence the models by Analyzing Models.

Additionally, mathematical models can be sensitive to initial conditions and parameters. Small changes in these values can lead to significant changes in the model's predictions. This is known as the butterfly effect, where a small change in one part of the system can have a large effect on the overall outcome. To explore the development and structuring of these models, consider the process of Creating Models.

A-Level Maths Tutor Summary: Mathematical models help us understand real-world phenomena by using maths. However, they're not perfect. They simplify complex systems, meaning they might miss out on important details like migration or diseases in population studies. They also make assumptions that might not always be true, like reactions happening in a closed system. Plus, a tiny change can have a big impact, making predictions tricky.
