I applied a range of analytic and numeric techniques to understand the behaviour of the simpler models, including sensitivity analyses to determine the parameters that most influenced the model output. A mathematical model is an abstract model that uses mathematical language to describe the behaviour of a system. Mathematical models can be classified according to use (description or optimization), degree of randomness (deterministic and stochastic), and degree of specificity (specific or general). objectives from the three possible sources ambiguous and considered it as a weakness but others find it to be strength of the model as well (Marsh, 2007). Open Document. It is equally as necessary to recognize these limitations as it is to recognize the value of such analyses. The simulation results clearly show advantages of mathematical modeling. Most of them unlike Mathematics because of its complexities and they find difficulty in understanding and analyzing it. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Disadvantages. In mathematical modelling, we translate our assumptions into the language of mathematics.

On the other hand in linear regression technique outliers can have huge effects on the regression and boundaries are linear in this technique. Spline estimates values using a mathematical function that minimizes overall surface curvature, resulting in a smooth . The foundation for models are mathematical equations based on physics that characterize how the air moves and heat and moisture are exchanged in the atmosphere. While modelling helps us in formulating ideas and identify underlying assumptions of a problem, there is a compromise. Able to test a product or system works before building it. Model-based software development and system design are based on the end-to-end use of formal, composable and manipulable models in the product life-cycle. Statistical data is essential to the scientific method. Interpretability, no need for feature scaling, works on both linear / non - linear problems.
