With the globalization of economy and the socialization of information, the market competition is becoming more and more fierce, and the competition of products has been changed from traditional price competition to technological content. The high-tech products with humanized experience have become the mainstream of the market. Enterprises continue to develop the soul.
       In order to adapt to new market changes, companies must meet the needs of different users with the fastest time to market, the best quality, the lowest cost and the best service. PLM technology is to adapt to the development of enterprises arising.
PLM technology to the present, a total of four stages.
The first stage - the management and reuse of data
PLM is mainly used to solve the sharing and reuse of enterprise technical information, focusing on how to focus on storing scattered product development information, to solve the redundant data redundancy, easy retrieval, to ensure data security and shared management and other business needs.
The core technology of this stage is to extract the unstructured data (such as AutoCAD drawings) in 2D drawings, such as structural data (eg, component information, BOM information, etc.) and establish a scientific classification management system to facilitate Data organization and retrieval.
The second stage - multi - management domain information integration
With the gradual development of enterprise information application, enterprise information environment gradually complex, such as: the use of a variety of CAD, two-dimensional three-dimensional hybrid use, ERP / MES / CRM and other information systems widely used. How to regulate the definition of product data information to facilitate the product data in the various business links and circulation, as an urgent need to solve the problem.
This stage of PLM technology is mainly concerned with the integration of tools and management information systems, to achieve a variety of CAD system integration, extraction of standardized, standardized information, and back-end ERP / MES / CRM systems such as two- Rapid data exchange, to avoid duplication of data caused by the definition of the problem, thereby enhancing the overall efficiency of the enterprise process.

Phase III - Extensive Collaborative Product Development
With the 3D design technology matures, the rapid development of Internet technology, PLM technology to the development of collaborative products, mainly in the following areas:
1, machine, electricity, soft, technology and other multi-professional collaboration: structure, electronic appliances, software, hydraulic, and manufacturing process planning and other professional collaborative development;
2, off-site collaboration: enterprises and more factories, more R & D institutions located in different places, how to achieve collaborative design through the PLM system;
3, customers, suppliers Collaboration: collaborative development with customers / suppliers, customer needs / changes can be timely and accurate delivery to the development team. Design information can be quickly delivered to suppliers, suppliers at any time to maintain collaborative development with the enterprise development team.

At present, the international mainstream PLM products are basically at this stage.
The fourth stage - the application of intelligent and virtualized product development technology
1, the use of large data and intelligent technology
With the deep application of enterprise information, how to carry out the deep excavation from the massive data of the enterprise, extract the valuable information, and provide support for the enterprise management decision to become a new topic.
Dassault's 3DExperience platform took the lead in the PLM intelligent era. 3DExperience will PLM develop into a unified product development support platform, R & D personnel used in a variety of design tools will run on this platform to ensure the flow of information on the timeliness and accuracy. And in the 3DExperience platform, a large number of large data analysis tools (EXALEAD) for intelligent query and data analysis, to solve the traditional PLM and BI systems are difficult to solve the problem:
From the query and analysis of structured and unstructured data

Application example: Through the intelligent data search engine, to achieve the design reuse parts
As we all know, every new part in the enterprise will bring a very surprising cost. Designers are designed to reuse existing components as much as possible, but how to find the required parts from existing information is a big challenge.
In the traditional PLM system, each component will be defined for the different attributes, through the property search. This approach has brought new problems, such as: in each part of the definition, the need to maintain a large number of attribute information, bringing a lot of work. And many structural parts, through the property can not be clearly defined, with the development of manufacturing technology and customer personal requirements increase, the proportion of such parts will be more and more.
