A model is a simplified description of things, phenomena, processes, or systems in the real world, or an imitation of some of their properties. In a general sense, it refers to a prototype made by imitating the shape of physical objects or structures in design, and its size can be divided into miniaturization, physical type, and enlargement. Some models even have the same details as the real object, while others only imitate the main features of the real object. The significance of models lies in their ability to visually understand the image of physical objects. In addition to having artistic appreciation value, they also have great utility in education, scientific research, industrial construction, civil engineering, and military affairs. With the advancement of science and technology, people view the research object as a system and study it from a holistic perspective. This type of systematic research is not about listing all facts and details, but about identifying significant influencing factors and interrelationships in order to grasp the essential laws. Various models can be established for the studied system through analogy, abstraction, and other means. This is called modeling. The model can take various forms and there is no unified classification principle. According to the representation of models, they can be divided into physical models, mathematical models, and structural models.

也稱(cheng)實(shi)體糢型(xing)，又可(ke)分爲(wei)實(shi)物(wu)糢型咊(he)類比(bi)糢(mo)型(xing)。①實(shi)物(wu)糢型：根(gen)據相佀性(xing)理(li)論製(zhi)造的按(an)原係統比例(li)縮(suo)小(xiao)（也可以昰(shi)放大(da)或與原係統尺寸(cun)一(yi)樣）的實物，例如風(feng)洞實(shi)驗中的飛機(ji)糢型，水(shui)力係統實(shi)驗(yan)糢型(xing)，建(jian)築糢(mo)型(xing)，舩舶(bo)糢(mo)型等(deng)。②類(lei)比(bi)糢(mo)型：在不衕的物理(li)學(xue)領域(yu)（力(li)學(xue)的(de)、電(dian)學的、熱(re)學的、流(liu)體(ti)力學(xue)的等）的係(xi)統中各(ge)自(zi)的(de)變量(liang)有時(shi)服(fu)從(cong)相(xiang)衕的(de)槼律，根據(ju)這(zhe)箇(ge)共(gong)衕槼律(lv)可以(yi)製齣物(wu)理意(yi)義(yi)完(wan)全不(bu)衕的(de)比(bi)擬咊類推的糢型。例如(ru)在(zai)一(yi)定條(tiao)件下由節流閥咊(he)氣(qi)容構(gou)成(cheng)的(de)氣動(dong)係統的壓(ya)力(li)響(xiang)應與(yu)一箇由(you)電(dian)阻咊(he)電(dian)容所(suo)構(gou)成(cheng)的電路(lu)的(de)輸齣(chu)電壓(ya)特性具有(you)相(xiang)佀(si)的槼律(lv)，囙(yin)此可(ke)以用(yong)比較容(rong)易進行(xing)實(shi)驗(yan)的(de)電路(lu)來糢(mo)擬氣(qi)動(dong)係統(tong)。

Also known as physical models, they can be divided into physical models and analog models Physical model: A physical model manufactured according to the theory of similarity, which is scaled down (or can be enlarged or the same size as the original system) according to the original system, such as an aircraft model in wind tunnel experiments, a hydraulic system experimental model, a building model, a ship model, etc Analogy model: In different fields of physics (mechanics, electricity, thermodynamics, fluid mechanics, etc.), the variables of each system sometimes follow the same law. Based on this common law, models with completely different physical meanings can be created for analogy and analogy. For example, under certain conditions, the pressure response of a pneumatic system composed of a throttle valve and a gas volume has a similar pattern to the output voltage characteristics of a circuit composed of resistance and capacitance. Therefore, a circuit that is relatively easy to experiment with can be used to simulate pneumatic systems.

A type of model described in mathematical language. A mathematical model can be an algebraic equation, differential equation, difference equation, integral equation, or statistical equation, or an appropriate combination of them, which quantitatively or qualitatively describes the interrelationships or causal relationships between variables in the system. In addition to mathematical models described by equations, there are also models described by other mathematical tools such as algebra, geometry, topology, mathematical logic, etc. It should be pointed out that mathematical models describe the behavior and characteristics of a system rather than its actual structure.

A model that mainly reflects the structural characteristics and causal relationships of the system. An important type of model in structural models is graph models. In addition, commonly used room models in biological system analysis also belong to structural models. Structural modeling is an effective means of studying complex systems.
