Intelligent manufacturing

An overview

Intelligent manufacturing deep in

artificial intelligence research.

Generally

think that intelligence is the sum of

knowledge and intelligence, the former

is the

basis

of

intelligence,

the

latter

is

the

ability to acquire and apply knowledge

to

solve.

Intelligent

manufacturing

should

contain intelligent manufacturing

technology

and intelligent manufacturing system.

The intelligence technique of

manufacture

is

refers

using

the

computer

simulation

marks

intelligent

activities

such

as expert's analysis, judgment,

inference,

idea and decision-making and so on, and

fuses

organically these intelligent activity

and

the intelligent machine, applies its

penetration in entire manufacture

enterprise's each subsystem (e.g.

management decision- making, purchase,

product design, productive plan,

manufacture,

assembly, quality assurance and market

sale

and so on).Realizes the entire

manufacture

highly

operation the manage to enterprise

flexibility and integration, thus

substitutes or extends in the

manufacture

environment expert's partial mental

labor,

and carries on the collection, the

memory, the

consummation, sharing, the inheritance

and

the development of the manufacturing

industry

expert's intelligent information,

enhances

the production efficiency enormously

and the

advanced technique of manufacture.

The intelligent manufacture system

is

refers based on IMT (intelligent

manufacturing technology), by the

computer

synthesis application artificial

intelligence technology (e.g.

artificial

neural networks, genetic algorithm and

so on),

the intelligence manufacture machine,

the

agent

technology,

the

parallel

projects,

the

life sciences and the systems

engineering

theory and the method, in the

international

standardization and interchangeable

foundation, causes the entire

enterprise to

make each subsystem to intellectualize

separately, and causes the manufacture

system

to form by the network integrates, the

high

automated one king of manufacture

system.

Intelligent manufacturing system can

not

only in practice constantly enrich the

knowledge base, have the function of

self-learning, and collecting and

understanding of environmental

information

and its information, analysis and

judgment

and the ability to plan their actions.

The basic principle

Starting from the essential feature of

intelligent manufacturing system in

distributed manufacturing network

environment,

according

to

the

basic

idea

of

distributed integration,In the

application

of distributed artificial intelligence

theory

and

method

of

multi

Agent

system,

realize flexible manufacturing unit of

the

intelligent and flexible manufacturing

system based on network intelligent

integration. According to the

characteristics of the distribution

system of

isomorphism in a local area forms for

realizing intelligent manufacturing

system

the

reflects also actual the on based

internet-based

global

manufacturing

the

realization of the intelligent

manufacturing

system model under the network

environment.

The overall idea of distributed IMS

network:

IMS is

the

essential characteristics

of

the individual manufacturing unit of

autonomy and the system as a whole

self-organizing ability, its basic

pattern

is

distributed

more

intelligent

system.

Based

on this understanding, and considering

the

internet-based global manufacturing

network

environment, we put forward the Agent

based

distributed

IMS

network's

basic

idea,

as

shown in figure 1. On the one hand,

through

the Agent give autonomy to each

manufacturing

unit, making it a fully functional,

autonomy,

an independent entity; On the other

hand,

through the coordination and

cooperation

between the Agent, gives system

self-organization ability.

Multi Agent system implementation

pattern

of the system is easy to design,

implementation and maintenance, reduce

the

complexity of the system, enhance the

system's

restructuring,

scalability

and

reliability, and improve the

flexibility,

adaptability

and

agility of

the system.

Based on the above framework,

combined

with the CNC machining system,

development

and application of distributed network

prototype system by system manager,

mission

planning, design and producers of four

nodes.

Systems manager node including two

database server, database server and

Agent

system

is

responsible

for

the

management

of

the entire global database, available

for

access of nodes in the prototype system

for

data

query,

read, storage and

retrieval

operations, and for each node for data

exchange and sharing, to provide a

public

system,

the

Agent

is

responsible

for

the

system in the network and the external

interaction, through the Web server on

the

Internet home page of the system, users

can

access

online

home

page

the

information

related to obtaining the system, and

decide

to needs, own their to according

whether the system is to meet these

requirements,

the

system

of

the

Agent

is

also

responsible for monitoring the

interactions

between the various nodes on prototype

system,

such as record and real-time display of

sending and receiving messages between

nodes,

task execution, etc.

Mission planning nodes by the task

manager and its Agent (task manager

Agent),

its main function is to task planning,

from

the Internet

is

decomposed

into

several

subtasks, and then through the way of

bidding,

bidding to the task allocation of each

node.

Design node by CAD tools and its

proxy

Agent (design), it provides a good

man-machine

interface

so

that

designers

can

effectively and computer interaction,

common

to complete the design task. CAD tools

to help

design personnel according to user

requirements for product design;

Designed the

Agent is responsible for online

registration,

cancellation registration, database

management, interaction with other

nodes,

decide

whether

to

accept

the

design

task

and

submit a task to task the sender.

Producers node is actually the project

research and development of an

intelligent

manufacturing system (intelligent

manufacturing unit), including

processing

center and its network proxy Agent

(machine).

The intelligent adaptive machining

center

configuration. The CNC system is

controlled

by intelligent controller processing

process,

to give full play to the processing of

automated processing equipment

potential,

improve processing efficiency; Have

certain

ability

of

self

diagnose

and

self

repair,

in

order to improve the processing the

reliability

and

safety

of

the equipment

operation;

Have

the

ability

to

interact

with

the external environment; With open

architecture to support the system

integration and extension.

The prototype system work:

Every node in the system must be

registered

through the network, to become the

formal

member

of

the

prototype

system

to

obtain

the

collaborate

to privileges, corresponding

with other nodes in the system, common

to

complete the system task. The whole

process

of operation of the prototype system is

as

follows:

(1)

any

network

user

can

access

the

prototype system of the home page for

information about the system, but also

through the fill out and submit user

order

form provided by the system home page

issued

orders

to

the

system;

(2)

if

received

and

accept

the

network

user's

orders,

Agent

system is to be deposited in the global

database, from the global database,

mission

planning nodes can take out the order,

mission

planning, the task decomposition into

several

subtasks, and assign these subtasks

prototype

system

access

nodes;

(3)

product

design

subtasks are assigned to design node,

the node

through

good

human-computer

interaction

to

complete product design sub-tasks,

generate

the corresponding CAD/CAPP data and

documents,

and

nc

code,

and

these

data

and

documents

in

the global

database,

finally

submit

the

subtasks

to

mission

planning

nodes;

(4)

producers,

to assigned are subtasks processing

once the subtasks was accepted by the

producers nodes, machine Agent will be

allowed to read the necessary data from

the

global database, and to transfer the

data to

the processing center, processing

center,

according to these data and command to

finish

processing

the

subtasks,

and

the

running

status information transmitted to the

machine

Agent,

Agent

returns

the

result

to the

mission planning nodes, submit the

subtask;

(5) in the system during the running of

the

whole, the Agent is the interaction

between

the various nodes in the system for

recording,

such as message sending and receiving,

a

global database data read and write,

query the

node name, type, address, ability, and

task

completion,

etc.

The development

Intelligent manufacturing deep in

artificial intelligence research.

Artificial

intelligence is the intelligence of

implementation of using artificial

method on

the complicated as the

WanShanHua

and the structure of the product

performance

and refinement, as well as the function

of

diversification, prompting a surge in

product

design information and process

information

contained, with internal information

flow

increase of production line and

production

equipment, manufacturing process and

management

information

must

also

soared,

a

hotspot and frontier, and thus prompt

the

development

of

manufacturing

technology

to

improve manufacturing system for the

explosive growth of manufacturing

information processing ability,

efficiency

and scale. At present, the advanced

manufacture equipment left the

information

input cannot operate, flexible

manufacturing

system (FMS) once they are cut off the

source

of

information

will

immediately

cease

to

work.

Expert

thinks,

the

manufacturing

system

is

driven by the original energy into

information driven, this requires a

flexible

manufacturing

system

requires

not

only,

but

also show that the intelligent,

otherwise it

is difficult to deal with such a large

amount

of workload and complex information.

Secondly,

the complex environment of rapidly

changing
