1、按照CIMDATA的定义

按照CIMDATA的定义，PLM主要包含三部分，即CAX软件（产品创新的工具类软件）、cPDM软件（产品创新的管理类软件，包括PDM和在网上共享产品模型信息的协同软件等）和相关的咨询服务。实质上，PLM与我国提出的C4P（CAD/CAPP/CAM/CAE/PDM），或者技术信息化基本上指的是同样的领域，即与产品创新有关的信息技术的总称。

2、PLM是一种理念

从另一个角度而言，PLM是一种理念，即对产品从创建到使用，到最终报废等全生命周期的产品数据信息进行管理的理念。在PLM理念产生之前，PDM主要是针对产品研发过程的数据和过程的管理。而在PLM理念之下，PDM的概念得到延伸，成为cPDM，即基于协同的PDM，可以实现研发部门、企业各相关部门，甚至企业间对产品数据的协同应用。软件厂商推出的PLM软件是PLM第三个层次的概念。这些软件部分地覆盖了CIMDATA定义中cPDM应包含的功能，即不仅针对研发过程中的产品数据进行管理，同时也包括产品数据在生产、营销、采购、服务、维修等部门的应用。

因此，实质上PLM有三个层面的概念，即PLM领域、PLM理念和PLM软件产品。而PLM软件的功能是PDM软件的扩展和延伸，PLM软件的核心是PDM软件。

What is the PLM definition?

As defined by CIMDATA

According to CIMDATA’s definition, PLM mainly consists of three parts, namely CAX software (tool software for product innovation), cPDM software (product innovation management software, including PDM and collaborative software for sharing product model information online) and related consulting services. In essence, PLM and China’s C4P (CAD/CAPP/CAM/CAE/PDM), or technology information basically refers to the same field, that is, the general term for information technology related to product innovation.

PLM is an idea

From another perspective, PLM is the concept of managing product data information throughout the product life cycle, from creation to use to final retirement. Before the concept of PLM came into being, PDM was mainly for the management of data and processes in the product development process. Under the concept of PLM, the concept of PDM has been extended to become cPDM, that is, collaborative PDM, which can realize the collaborative application of product data between the research and development department, the relevant departments of the enterprise, and even between enterprises. PLM software from software vendors is the concept of the third level of PLM. These software partially cover the functions that cPDM should include in CIMDATA’s definition. That is, management of product data not only in the development process. But also in the application of product data in production, marketing, purchasing, service, maintenance, etc. Digital transformation network szhzxw.cn

Therefore, in essence, PLM has three levels of concept, namely PLM domain, PLM concept, and PLM software product. The function of PLM software is the extension and extension of PDM software. The core of PLM software is PDM software. Digital transformation network szhzxw.cn
