The application of PLM information system in the design industry

"Rome was not built in a day". To achieve the goal of collaborative design, it is necessary to change the working habits of designers and even the whole industry for more than ten years, and it is inevitable to encounter resistance in the process of deployment. According to the experience of deploying information systems in the manufacturing industry, the promotion of enterprise information systems will take at least half a year to adapt

1 introduction to PLM

plm is a technology for product development process. It is based on computer network technology and database technology, and takes object-oriented technology as a means. It is the realization of information-based enterprise level product development process in computer system. It provides a necessary environment for enterprises to build a product concurrent development (product design, manufacturing process) team. Its specific functions include: life cycle management, workflow and developer management, electronic data warehousing management, product structure management, part family management, product change management, product configuration management and so on. With the continuous development of Internet technology, its concept is also constantly updated

2 application of PLM information system in manufacturing

according to cimdata analysis, the average growth rate of the global PLM market from 2007 to 2011 was 8.5%, of which the average growth rate of tool software such as mechanical CAD, cam, CAE, EDA and dynamic publishing was 5.3%

the steady growth of PLM Software demand from manufacturing enterprises has given PLM manufacturers the driving force for development. Whether it is a platform level PLM manufacturer or a professional manufacturer specializing in a specific industry, it has made great progress. The application of PLM has also been registered in Shenzhen, and enwan technology is constantly popularized from high-end to middle-end. Pharmaceutical, tobacco, steel and other industries have their own PLM solutions for managing product formulations, processes, development documents and R & D processes. Many enterprises that are going to be world-class are increasingly aware that to be a first-class enterprise, they must have a first-class product strategy. To achieve a first-class product strategy, they must have a set of PLM system to support it

3 PLM in the design industry

for enterprises in the design industry, their greatest wealth and capital is the knowledge accumulated by the enterprise itself after several years of accumulation. At present, computer-aided design and drafting has been very popular. Most of the technical data in the design industry adhere to the problem orientation in the form of electronic documents. How to integrate and utilize these scattered data, strengthen the management and control of the design process, and seek new profit growth points for enterprises is an urgent problem to be solved in the design industry. The PLM information system, which plays an important role in manufacturing applications, has become a possible research direction

3.1 the original requirements of the design industry for information systems

1 centralized and effective project document directory management

the common phenomenon in the design industry at present is that the working documents of designers are managed by themselves, and enterprise leaders and project managers lack a comprehensive grasp of the project design work, which is difficult to monitor. Even if the designated personnel regularly summarize and collect the data of various designers, it is difficult to guarantee the integrity and real-time of the data

it is necessary to establish a directory of all the contents of the design process, and collect and manage them through the PLM system, so that enterprise leaders at all levels, project managers and relevant designers can browse the project contents completely and master the project progress according to their own permissions

2 ensure the integrity, consistency and accuracy of information

generally speaking, the design documents generated by design enterprises in the design process include 2D/3D drawings generated by various CAD/CAM systems, office and PDF series documents, pictures and various data and test reports generated by other professional software. The information system shall meet the regular storage of documents, and use relevant storage technology to meet the rapid browsing, modification, storage and printing of these documents

all majors use the PLM system as the working platform, and all materials are submitted to the PLM system. Through the access control mechanism, version management, document management and other functions, the integrity and accuracy of all information contents are guaranteed, and all contents are updated in time, and users get the latest information

3 ensure the security of project data

the system provides document operation permissions according to different permissions and encryption processing of warehousing files to ensure data security. Permissions include document creation, browsing, check-in, check-out, circling, downloading, printing, batch warehousing, batch delivery, etc

4 process management and collaborative design

process management should be divided into two parts. One part is the supporting process, including the support of functional departments to the design department, such as personnel department, finance department, quality control department, office and other functional management departments and the interactive process generated by the design department; the other part is to focus on the design process, from the establishment of the design project to the determination of the scheme, and then to the realization of the design product, The quality control system is closely combined with the system, and the process of information system automation is used to achieve the purpose of collaborative design, so as to greatly improve the design quality

5 establishment of standard database

by establishing an enterprise level PLM system, the design data of the enterprise will be stored and organized uniformly, which will greatly improve the reusability of existing design data, avoid repeated investment, and save design costs. The essence of standard database is knowledge management, which is also the basis for PLM information system to maximize its benefits

6 demand for digital assessment

design industry due to the uniqueness and particularity of its products. There is often a lack of fair and effective evaluation methods when evaluating the design workload. When the scale of design enterprises continues to expand, the statistics and analysis of the status, ability and workload of designers will become more and more important. At present, the performance evaluation of designers in most design enterprises is still in the manual stage, and there is a lack of data collection and analysis in the design process as the basis for evaluation. The ultimate goal of PLM system is collaborative design. Key processes such as input and output and changes in the design process are tracked and recorded in the system, making it possible for the system to collect first-hand data in real time

3.2 differences between design industry and manufacturing industry

compared with the already mature automatic control of production process in manufacturing industry, the demand for information system in design industry is quite different from that in manufacturing industry. The design industry pays attention to the content management of engineering projects. For any engineering project, many departments and units will participate in it at different stages with different degrees of participation, including owners, design units, construction contractors, supervision companies, suppliers, etc. At present, all participants often use the traditional point-to-point communication method in the process of the project, which not only increases the cost and increases the cost, but also cannot guarantee the timeliness and accuracy of the communication information content. As a design unit, we need to first form norms, implement management, accumulate experience and provide data in informatization. We believe that the characteristics of design industry information system include the following contents:

knowledge management is the core of information system. The design industry enterprise is an intensive enterprise with higher efficiency of knowledge transmission. It takes knowledge management as the core, and mainly completes the collection, sorting and processing of design input conditions, the exchange of design interfaces, and the design of finished products

emphasize information sharing and integration. The biggest difference between collaborative design in the design industry and collaborative design in production-oriented enterprises is that design institutes emphasize collaborative design, pay attention to the sharing and integration of information, and production-oriented enterprises emphasize process control. Pay attention to the management of the whole production supply chain and production process control

effective integration with existing systems. The design industry has developed for many years. Generally, there are a large number of systems in operation, such as personnel management, business plan management, project management, OA office automation, publishing management, etc. a comprehensive PLM system must establish interfaces with these systems. To ensure the uniqueness and effectiveness of data, otherwise new information islands will be formed

flexibility and customizability of the system. Different from production-oriented enterprises, production-oriented enterprises have design before market. A finalized product can often support a long-term market supply: the products of the design institute are customized on demand, and each individual product is unique. Therefore, the PLM system in the design industry must be a flexible system, which can meet the requirements of design business growth and application mode changes, which requires the system to have flexible customization and definition

the objects of system management are different. The products of the design industry are mainly reports, drawings and documents generated in the design process (mutual submission of information, calculations, etc.). Therefore, the main management content of the information management system of the design industry is documents and data

3.3 step by step deployment strategy

"Rome was not built in a day". To achieve the goal of collaborative design, it is necessary to change the working habits of designers and even the whole industry for several years, and it is inevitable to encounter resistance in the process of deployment. According to the experience of deploying information systems in the manufacturing industry, the promotion of enterprise information systems will take at least half a year to adapt

The same is true in the design industry, but due to the particularity of the design industry, the acquisition of the original data of the information system must directly rely on the cooperation of designers. Therefore, the author believes that the promotion of PLM system in the design industry needs to adopt a step-by-step strategy. Through this progressive way, gradually change the habits of designers, and explore repeatedly in practice in combination with the characteristics of the design industry to seek PLM solutions for the design industry.
