Description
Technical field
The present invention relates to computer application, engineering design exploitation and product intelligent design fields, more particularly, to a kind of base
In the complex product ecological network modeling method of complex network.
Background technique
In ecology, the ecosystem refers to generated one of both biology and its place environment interaction relatively
Stable system.The ecosystem can by internal self-organizing process adapt to external environment variation complication system, have self-organizing,
Adaptive feature.Population is component part important in the ecosystem, for any one population, the existence of each individual
All rely on external environment, each of population individual all with other individual (same populations or other populations),
And energy, the exchange or transmitting of substance occur for inorganic environment.
Energy transmission in the ecosystem between population and population is carried out in a manner of food chain.So-called food chain refers to
The chain-type relationship to connect with one another closely formed in nutrition relationship between different plant species in the ecosystem, matter and energy along
Food chain is transferred to advanced species from rudimentary species one by one, reduces step by step along the quantity of food chain population at individual, kind
Group's density reduces step by step, and proliferative speed slows down step by step.It is wide that a bottom is formd relatively with the individual amount of biotic population in this way
The narrow ecological pyramids in top.
The Evolutionary Design of complex product (such as: engine) is related to multiple components, is a complicated Multi-variables optimum design
Problem, if using traditional genetic algorithm, it may appear that coding is tediously long, and convergence rate is slow, the problem of effect of optimization difference.By right
Compare the ecosystem, it is possible to find complex product and the ecosystem have similitude in function, structure: they are all by a variety of group of individuals
At with complicated internal organizational structure, higher complexity is presented in system；In certain circumstances, system has stable
Institutional framework, the state in energy balance；System is completed by mass exchange, energy flow and the information transmitting between individual
Certain function.
It is in complex product Evolutionary Design also there is similitude with the evolutionary process of the ecosystem: the change of population at individual
To change include births & deaths, the periods such as moves into, moves out, evolving, and product individual has the life of generation, evolutions, superseded disappearance simultaneously
Period；Food chain, energy flow relationship between biotic population and environment, biotic population also exist in complex product.Product
Substance, energy and information exchange are carried out with environment to adapt to environment.
In complex product, by the extraction and decomposition to product parts, it can define all products by voxel structured approach
Part, and the complex network that entire complex product is made of each part.The two dimension that complex network is made of node and side
Figure.From graph theory, network G=(V, E) refers to a figure being made of a point set V (G) and side collection E (G), and E
(G) each edge in has a pair of of point (u, v) in V (G) to be corresponding to it；From Statistical Physics, network is one and contains greatly
The system to interact between amount individual and individual is certain phenomenon or certain relationship to be abstracted as between individual and individual
The figure for being used to describe this phenomenon or relationship of interaction and formation.
The complexity of complex network is from three aspects: (1) node complexity.I.e. only by the non-linear phase between node
Complicated system action caused by interaction, such as fork and chaos；(2) structural complexity.The element of complicated composition system it
Between structural relation it is both irregular, it is also nonrandom, but fall between, and this structural relation can also become at any time
Change, and influence the behaviour that system is integrally shown, is one of deciding factor of system complexity；(3) various complexity
Factor influences each other.
Complex network G=(V, E) refers to a figure being made of a point set V (G) and side collection E (G), and E (G)
In each edge there is a pair of of point (u, v) in V (G) to be corresponding to it, in G=(V, E), V be vertex finite nonempty set close, E is V
The finite aggregate of middle vertex couple (referred to as side).In general, the vertex set for scheming G and side collection are also denoted as V (G) and E (G) respectively.E(G)
It can be empty set.If E (G) is sky, schemes G and only have vertex without side.There are the product of 9 parts, network for one
It indicates shown in Fig. 1, A-J is vertex set V in Fig. 1, and R () is side collection E.
Therefore, how the concept of the ecosystem to be incorporated in the design that complex network and complex product are evolved, realizes base
In the product design of complex product ecological network, it is of great significance.
