A model is a new object that reflects all the main features of the subject that is being studied. In all areas of science they are examined from different angles of view. One and the same object can have several models, while many of them can be reflected in one. We need it in order to be able to present or describe something. For example, when developing a new aircraft engine, designers must check its process in difficult flight conditions. After all, to realize this in reality is to endanger the test pilot. Therefore, the possible flight conditions can be simulated on special stands.
It follows that modeling is safety and a wide range of conditions. Any model, one way or another, must correspond to the object, and it can be similar to it in:
- appearance;
- structure;
- behavior.
Modeling is the main method of cognition, which consists of the creation and study of objects. It is used to obtain complete information about the process under study, which is necessary for the optimal solution of the tasks. But at the same time, no model can replace a real event. Only when solving specific problems can it prove to be useful, and sometimes the only research tool.
Modeling is:
- replacing the real process with its imitation;
- building a model of real-life objects or events;
- research on the created sample.
From the foregoing, it follows that modeling is an integral part of any purposeful activity.
Classification
System modeling is conditionally divided into 3 classes:
1. Material.
2. Abstract.
3. Informational.
The prototyping process itself consists of the following steps:
1. The designation of the goal.
2. Analysis of all system properties.
3. The selection of the most important signs.
4. The choice of form.
5. Formalization.
6. Analysis of the model at the output.
7. Checking the adequacy of the obtained sample system and the purpose of the entire study.
Modeling and formalization
Natural languages are designed to create imaging information models. Formal ones allow you to build external samples. This process is called formalization.
One of the most common formal languages is mathematical - it is he who makes it possible to formulate functionality between quantities. In this way, Newton formalized the heliocentric system of the world, first discovering the law of gravity and the law of mechanics and writing them in the form of mathematical dependencies.
People use modeling and formation all the time to learn everything around them. But what does formalization mean? This is a reduction of some content of the selected form. For example, the table of contents of a book is the formalization of its content, and the text itself is a formulation through linguistic thoughts, thoughts and ideas of the author.
The possibility of this process is based on a fundamental position, which is called the main thesis. The essence of an object or system does not change from what we call them. And this means that they need to be named so that this name matches them as much as possible. Denial of the main thesis of formalization means that the name of this object or system should express its essence. Therefore, in this case only one name should be given.
