Computer emulation book notes

First, we have a general understanding of the definition of computer simulation, the development of the subject, the scope and method of research.

Reading brinton, etc of the modern computer simulation technology, to know and understand the aspects: the computer simulation is the combination of computer technology and simulation technology of a discipline, in this paper computer simulation for the following definition: the computer simulation is the entity does not yet exist or entity exists but is not easy to handle on entity, by investigating the related parameters, combined with the related research areas, establish mathematical model, and then implemented programming in a computer, by changing the relative parameters and the internal and external environmental changes, to achieve a comprehensive understanding of the characteristics of the entity. The mathematical model here, I think, should also expand the concept of models, including physical models and some non-descriptive models.

Mentioned in this paper the development of simulation technology, including three stages, analog phase, can only rely on physical simulation, the disadvantages can't fine simulation, cost is high; In the analog digital phase, some of the digital technologies have been used to improve the shortcomings of the simulation phase. Digital stage, no physical intervention, complete digitization, can complete many large non-real-time simulation process accurately, the reliability of simulation improve.

And steps of simulation, the article mentioned: first obtain the related professional knowledge, according to research purposes to determine relevant parameters and characteristic value, on the basis of these established a preliminary mathematical model, after many test, adjust parameters, get an improved model, it is a secondary process of modeling.

The end of the article explains the computer simulation technology application scope is widespread, in th
