What is a model is introduced as follows:
The model is an object (object is not the same as the object, not limited to physical and virtual, not limited to the plane and the three-dimensional) that constitutes an objectively articulated morphological structure through the subjective consciousness of the physical or virtual representation.
Expansion of the introduction:
I. The concept of the model ?
The model is through the subjective consciousness with the help of physical or virtual performance constitutes the objective elaboration of the structure of the form of an object to express the purpose of the object (the object is not the same as the object, is not limited to the physical and virtual, is not limited to the plane and three-dimensional).
The classification of models?
1, mathematical models
A class of models described in mathematical language.
2, physical models
Also known as solid models, can be divided into physical models and analogical models.
3, structural model
Model that mainly reflects the structural characteristics of the system and cause and effect relationships.
4, industrial model
Industrial model, commonly known as the hand plate, the first board model and rapid prototyping, the main production methods are CNC machining, laser rapid prototyping and silicone mold small batch production.
5, simulation model
Through the digital computer, analog computer or hybrid computer running on the program expression of the model.
6, human resources model
Enterprises use a variety of resources, but "all the material factors can only be developed and utilized through the human factor", therefore, "people" is the most valuable resource, which has been generally recognized. This has been universally recognized.
7, thinking model
With simple and easy to understand graphics, symbols, structured language and other forms of expression of people's thinking and problem solving, collectively referred to as the thinking model.
