Computer simulation is widely used in various branches of science and technology, gradually displacing the real experiments and experiences.It is so firmly established in our lives that is already quite difficult to imagine a situation when you have to study this way the real world to give.This phenomenon is explained easily enough: with the help of this process it is possible to achieve significant results in the very shortest time, will penetrate into the region of reality, which is not achievable for a person.
computer information modeling allows the computer to create a model that with some assumption has the properties of a real object or process, and the study was carried out on this model created.To conduct research necessary to accurately represent what they are carried out, what their purpose is, what kind of property, the parties studied object you are interested in.Only in this case, you can be confident of a positive result.
Like any other process, computer simulation is based on certain principles, among which are the following:
· the principle of sufficiency of information.If information about the actual process or object will not be enough to carry out studies using this method probably will not work;
· the principle of feasibility.The created model should allow the researcher to achieve its objectives;
· the principle of plurality of models, which is based on the fact that for the study of the properties of the real object is necessary to develop several models, so how to combine all of the real property in the same is not possible;
· the principle of aggregation.In this case, the complex object is represented as a separate unit that can rebuild a certain way;
· paratmerizatsii principle, which allows the settings of a particular subsystem to replace the numeric values that reducing the amount and duration of the simulation, also reduces the value of the resulting model.Therefore, the application of this principle must be fully justified.
Computer modeling should be carried out in certain strictly specified sequence.The first stage is defined by the goal, and then made the development of a conceptual model.Then, the formalization of the model allows for the implementation of its program.After that you can start planning model experiments and implement a plan drawn up earlier experiment.After all the previous paragraphs are fulfilled, it will be possible to analyze and interpret the results.
In recent computer simulations of physical processes is performed using various applications.You can find a large amount of work carried out in Matlab.Such studies allow us to study all kinds of physical processes that in reality people will not be able to watch.
Computer modeling is quite widely used in industry.With his help develop new products, design new machines, set the conditions of their work and conduct virtual tests.If the model has compiled a sufficient degree of adequacy, it can be argued that the results of real tests will be similar to the virtual.In addition to studying the properties of a system, the computer can develop the look of the finished product, to specify its parameters.This minimizes the number of marriages that may occur as a result of malfunctioning of engineering calculations.
