Analysis of Enterprise Lifecycle Management PLM Selection

1 PLM definitions and functions

One of the primary tasks and effective ways to enhance the core competitiveness of enterprises is to speed up the informationization process of enterprises and rely on information technology to develop better and newer products, effectively increase revenue and reduce costs.

1.1 Definition

PLM, product lifecycle management. It includes: incubation period, growth period, maturity period, recession period, and end period. According to the definition of CIMDATA, the industry's authoritative, PLM is a product that is used in a single-site enterprise, dispersed within multiple locations, and between companies with collaborative relationships in product development. A range of application solutions for the creation, management, distribution and application of information that integrates product-related human resources, processes, applications and information. In essence, PLM has three levels of concepts: PLM, PLM, and PLM. The function of PLM software is the extension and extension of PDM software. The core of PLM software is PDM (Product Data Management).

1.2 Features

The PLM system fully supports the conception, evaluation, development, management and support of products throughout the digital product value chain. It integrates multiple unconnected product information silos in the enterprise into a digital recording system, with enterprise resource planning (ERP), supply. Chain management (SCM) and customer relationship management (CRM) together form a complete enterprise information collaboration system. It mainly includes basic technologies and standards (such as XML, visualization, collaboration and enterprise application integration), information creation and analysis tools (such as mechanical CAD, electrical CAD, CAM, CAE, computer-aided software engineering (CASE), information release tools, etc. ), core functions (such as data warehousing, document and content management, workflow and task management, etc.), application functions (such as configuration management), business/industry-oriented solutions and consulting services (such as automotive and high-tech industries).

2 PLM produces background

The management of product technology design data in the early days is called graph document management, which mainly solves a large number of engineering drawings and document storage problems generated in the design, and realizes digitization, sharing, version management, and authority control of drawings. Later, enterprises need higher requirements, that is, not only the design results are managed, but also the design process should be managed. PDM (product data management) emerges as the times require and begins to be applied in manufacturing. With the intensification of competition, manufacturing companies pay more and more attention to standardization, serialization and modularization in product development, process design and production. Therefore, new demands for PDM are emerging, process design and process management, product configuration. Management, change management, and R&D project management are important components of PDM. In the 21st century, in the e-commerce boom, many new technologies and new concepts have emerged. PLM is proposed in this context. PLM emphasizes extending the management scope to the entire cycle of products, from the production process to the use. The whole process of scrapping and disappearing. PLM fully includes the entire contents of PDM, which is a subset of PLM. However, PLM also emphasizes the concept of managing and utilizing all information across the supply chain during the product life cycle, which is the essential difference from PDM.

3 PLM development and status quo

During the period from 2002 to 2004, PLM was once popular. In the four systems of ERP, SCM, CRM and PLM, the growth and maturity of PLM took the longest time and was least understood. It is also quite different from other systems because it is by far the only system for product innovation and the most interoperable system.

According to analysis reports of some world-renowned consulting companies, the fastest growing IT companies in developed countries are PLM, and the market response and growth rate have exceeded ERP. Analysis from Aberdeen shows that after full implementation of PLM, enterprises can save 5% to 10% of direct material costs, increase inventory turnover by 20% to 40%, reduce development costs by 10% to 20%, and increase market access time by 15%. ～50%, reducing the cost for quality assurance by 15% to 20%, reducing manufacturing costs by 10%, and increasing productivity by 25% to 60%.

At present, the domestic PLM market has a relatively concentrated market share, and a small number of manufacturers occupy most of the market share. Among them, foreign representative manufacturers mainly include PTC, SIEMENS, Dassault, occupying the main market share of the domestic PLM market, especially the high-end enterprise market; domestic representative manufacturers mainly include UFIDA, CAXA, Axter, Qingying Yingtai, and opening eyes. , Sipu, Dingjie, Huatian, Tianhe, Tianyu, etc., but the share is relatively small compared with foreign manufacturers, mainly used in the low-end market.

Coal Activated Carbon For Recycling Of Solvents

Using high quality coal as raw material for solvent recovery, coal is mainly used in the recovery of benzene, toluene, ether, alcohols, gasoline, three, methyl chloride, organic solvents and other hydrocarbons, as well as the vapor recovery of hydrocarbon compounds.

Use: Used in the seperation and recycling of aethers, ketons, alcohols, tetrahydrofuran, methylene dichloride, trichloromethane, trichloroethylene, chlorinated polyvinyl chloride, carbon bisulfide, benzene, gasoline etc.
