Model-Simply stated about a real object, process or phenomenon.
Modeling- Pobudova models for the investigation and development of objects, processes, and phenomena.
Question: It’s time to create a model, why not trace the original itself?
First of all, in real time, the original (prototype) may no longer exist, or there really isn’t any
In another way, the original may have a lot of power and interconnections. In order to deeply understand any specific power that can taunt us, it is sometimes difficult to see less things that are not at all healthy.
Modeling is possible
For one and the same object (processes, objects) a number of models can be created

About computer modeling
Computer models have become an essential tool for mathematical modeling and are used in physics, astrophysics, mechanics, chemistry, biology, economics, sociology, meteorology, and other sciences and applications. They are located in various fields of radio electronics, machinery, automobiles, etc. Computer models are used to obtain new knowledge about the object that is being modeled, and for a closer assessment of the behavior of systems that are too complex for analytical tracking. Computer modeling is one of the effective methods for developing folding systems. Computer models are simpler and easier to follow due to their ability to carry out the so-called. Computational experiments, like real experiments, are complicated through financial and physical transfers and may result in non-transfer of results. The logic and formalization of computer models makes it possible to identify the main factors that indicate the power of the original object under investigation (or a whole class of objects), at a glance, to trace the influence of The physical system that is being modeled is based on changes in parameters and brains.
Slide 4
The computer model is based on the abstraction of the concrete nature of the phenomena or the original object, which evolves and is formed in two stages - initially clear, and then complex ї models. The more significant powers are identified and transferred to the computer model, the closer the system will be to the real model, the more capable the system, like the vikory model, will be. Computer modeling is based on a series of computational experiments on a computer, such as analysis, interpretation and comparison of the results of modeling with the real behavior of the object being studied, and, if necessary, further refine the model, etc. Disaggregate analytical and imitative modeling. In analytical modeling, mathematical (abstract) models of a real object are considered in the form of algebraic, differential and other levels, and also they are transferred to these unambiguous computational procedures, which lead to That's the exact truth. In simulation modeling, mathematical models are followed as algorithm(s) that enable the functioning of the monitored system through the sequential execution of a large number of elementary operations.

Models of objects and processes
A model is a simple statement about a real object, process or phenomenon. Modeling - the creation of models for the investigation and development of objects, processes, and phenomena. Models of objects can be modified copies of architectural disputes and artistic creations, and can be used as references in the school office, etc. bud. The model can be differentiated in a really simple way, say, an atom of water. Sleepy system, lightning discharge. Classification of models Models are classified according to the following signs: Vicor area Model appearance of time-hour factor (dynamics) Galuz know Method of presentation of models

Models Initial Updates
Scientific and technical
Game Simulations
Beginning models – basic aids, various exercise equipment, basic programs. The finalized model is a change or enlarged copy of the object being designed. For example, a model of a ship is tested in a pool to determine the stability of the ship during performance. Scientific and technical models – for further investigation of processes and objects. For example, an attachment that has a flash discharge. Gaming models include industrial, economical, sports and business games. They rehearse the behavior of the object in different situations. Simulation models are an experiment that has reality. For example, let’s say the school wants to introduce a new subject. Select a low school for the experiment, and then check the results.

Material models represent geometric and physical properties of the original and can be truly realized. butt. Children's games, dropped the birds, maps of history, geography, a model of a rocket, etc. Information models - they cannot be seen or touched with the naked eye, they do not carry any material significance. They will be deprived of information. An information model is a set of information that characterizes the power of an object, a process, a phenomenon. The verbal model is an informational model in a mental or philosophical form. For example, a person’s behavior when crossing the street. The person analyzes the situation and then takes action. A sign model is an information model, expressed by special signs. in any formal way. Butt, little things, texts, graphics and diagrams. A computer model is a model implemented by means of a software environment. For example, a computer program (music editor) that allows you to type music text, create music, create arrangements.
Computer modeling Based on the method of implementing information, sign models are divided into computers and non-computers. The computer model is the same model, implemented by means of a software middleware. Stages of modeling 1. Statement of the problem. 2. Model development. 3. Computer experiment. 4.

Analysis of the results of the fashion lyuvannya The results are consistent with the results The results are not consistent with the results The statement of tasks or problem) is formulated in basic terms, and the description is clear. The main stage of this stage is to identify the object of modeling and understanding. What is the result? Formulation and modeling The goals of modeling can be: knowledge of the full world, the creation of objects from given authorities (“how to create, so that …”), the identification of successions flowing into the object and making the right decision (“what will be, yakscho..."), efficiency of object (process) management, etc. Analysis of the object At this stage, proceeding from the formal formulation of the task, one can clearly see the object that is being modeled and its main powers. The fragments of a large output object are a totality of smaller warehouses that have a certain interconnection, then the analysis of the object is based on the decomposition (dismemberment) of the object from the identification of warehouses and the nature of the ligaments associated with them. p align="justify"> Development of the model At this stage, the authorities are revealed, and other characteristics of elementary objects are formed, statements are formed about the elementary objects, which become the output object, then. Information model. Information model Sign model An information model, as a rule, is presented in one or another sign form, which can be computer or non-computer. There is a large number of software systems that allow one to carry out research (modeling) of information models. The skin medium has its own toolkit and allows you to work with many types of information objects, which raises the problem of choosing the most convenient and effective medium to achieve the task. Computer experiment Modeling plan The modeling plan is to reflect the sequence of work from the model. The first points in such a plan may be development of the test and testing of the model. Testing is the process of verifying the correctness of the model. A test is a set of output data that will later reveal the result. For differences in test values, it is necessary to find out the reason. Modeling technology Modeling technology is the totality of the direct actions of a computer scientist on a computer model. Analysis of modeling results. The results support the goals. The results do not support the goals. In this case, the analysis of the model itself is carried out, in order to correct the modeling errors.
