According to Wilson’s definition a model is the explicit interpretation of one’s understanding of a situation, or simply of one’s idea about that situation. It can be expressed in mathematics, symbols or words. But it is essentially a description of entities, process or attributes and the relationships between them. It may be prescriptive or illustrative, but about all, it must be useful.
Describe the purpose and uses of models
There are various use of models; here I am going to focus on seven of them:
Firstly, a model helps us concentrate on the essentials of a complex problem, designing a model force us to think logically and clearly. We have to consider what we know, what we don't know, and what data we have available.
Secondly models are used to illustrate a concept, which help us to understand the problem situation better, they can also reveal part of the bigger picture and even show what’s missing.
Thirdly, models are used to defining structure, process and behaviors, it reveal complexity in simple systems like the structure of a virus.
Fourthly, models can be used as prerequisite to design.
Fifthly, model is a tool for communication, for example map communication tools will help us to identify the communication between stakeholders and enable us to understand, motivate and communicate effective with others.
Sixthly, models are used for predicting behavior such as perdition of weather forecast, prediction models will help us estimated and predict future outcome in order to decrease risks. A good example could be mathematical model
Lastly model can help us optimizing in different environment, in order to make sure quality planning with maximum efficiency.

Models can help us predict possible outcomes, such as global warming, hurricane, spread of disease. For example today’s forecasters use a...
