PLM is the product information framework of enterprises and their supply chains. It consists of various information elements: basic technologies and standards (such as XML, visual computing, collaboration and enterprise application integration), information generation tools (such as MCAD, ECAD and technology release), core functions (such as data warehouse, document and content management, workflow and project management), functional applications (such as configuration management) and business solutions based on other systems.
The difference between PLM and PDM is that:
1, essentially different: PDM provides information management of product life cycle, and can establish a parallel collaborative environment for product design and manufacturing within enterprises. PLM emphasizes the concept of managing and utilizing all information in the whole supply chain during the product life cycle, which is essentially different from PDM.
2. Different concepts: PLM is product life cycle management and PDM is product data management. PDM is a technology for managing all product-related information, including parts information, configuration, documents, CAD files, structures, authority information, etc. ) and all product-related processes (including process definition and management). In short, PDM is a series of technologies.
3.PDM is a part of PLM: PLM mainly includes three parts, namely CAX software (tool software for product innovation), cPDM software (management software for product innovation, including PDM and collaborative software for enjoying product model information on the Internet) and related consulting services. It can be seen that PLM completely contains all the contents of PDM, and PDM function is a subset of PLM.
Extended data:
PLM mainly includes three parts, namely CAX software (tool software for product innovation), cPDM software (management software for product innovation, including PDM and collaboration software for enjoying product model information on the Internet) and related consulting services. In essence, PLM basically refers to the same field as C4P(CAD/CAPP/CAM/CAE/PDM) or technical informatization proposed by China. .
That is, the floorboard of information technology related to product innovation. From another point of view, PLM is an idea, that is, the idea of managing product data information in the whole life cycle from creation to use to final scrapping.
Before the idea of PLM came into being, PDM was mainly aimed at data and process management of product development process. Under the PLM concept, the concept of PDM is extended to cPDM, that is, PDM based on collaboration, which can realize the collaborative application of product data among R&D departments, related departments of enterprises and even enterprises.
PLM software introduced by software vendors is the third-level concept of PLM. These software parts cover the functions that cPDM should include in the definition of CIMDATA, that is, not only the management of product data in the R&D process, but also the application of product data in production, marketing, procurement, service, maintenance and other departments.
Therefore, in essence, PLM has three concepts, namely, PLM field, PLM concept and PLM software products. The function of PLM software is an extension of PDM software, the core of which is PDM software.
