Abstract:

at present MES have become popular in the manufacturing industry, however, many companies ignore the data source, MES as the informatization of manufacturing execution system, how can we make the successful implementation in the enterprise, to play a greater role, it also requires the support of PDM system. In this paper, the integration of MES and PDM are simply discussed, and an actual example to verify.

Introduction：

In order to adapt to the at home and abroad The changing market environment, the state proposed "China manufacturing 2025" this ambitious plan, in order to enhance the quality and level of development of China manufacturing industry, two (promoting industrialization and information fusion) to a new height.So now the "intelligent manufacturing" has become a very hot topic, but the MES system has become hot in the manufacturing industry.

However, the enterprise informationization construction overall planning , Can not be done overnight , Not simply follow the trend . Will the whole enterprise information platform is composed of a plurality of system , ERP system, PDM system, MES system is an important part of the information platform, each enterprise on a system is a management change, every change to the necessary conditions. You or your business ready.

System introduction:

This article will talk about the two information system of enterprise PDM and MES, so we need to have a preliminary understanding of the concept of the two systems.

The PDM system is the product data management (Product Data Manager ), the industry renowned PDM consultancy services company CIMdata has made a definitive explanation: PDM is to help engineers and other personnel management of product data and the product development process tools.

PDM tracking system to ensure that the design and manufacture of the large amount of data and information required, and thus support and maintenance products. In short, all of the information management system of PDM enterprise products, including product documentation, product drawings, digital model, structured product data such as process data, but also the management process of these data is generated (work flow, change process). So PDM began to manage the full life cycle of data products from the source of enterprise product data.

Is MES Manufacturing Execution System abbreviation , Manufacturing Execution System That is a manufacturing enterprise oriented execution layer production information management system. MES Contain The number of modules , Such as manufacturing data management, scheduling management, scheduling management, inventory management, quality management, human resource management, work center / equipment management, tooling management, procurement management, project cost management, Kanban management, production process control, data analysis, data integration in the upper decomposition. , But the core or the implementation of Production planning and scheduling management, is the effective way to achieve fine management.

The necessity of the integration of:

therefore , So to speak The design process of PDM data and the management of the entire enterprise, while the MES system is responsible for the implementation of on-site production operations, including management of people and equipment. The design of data transformation of the specific implementation plan for the development of the production, receiving MES system data to better, this is very important.

In order to improve the product design to the production process of efficiency and accuracy MES, the system must be able to get directly from the PDM system to design data for production process, such as information processing drawings, products, and the manufacturing process of each process work instruction documents etc..

In the production process MES, the system can also according to the production conditions, collecting various data of production site, optimized for the product in the production process, product assembly instruction, can these data feedback to the design department in a timely manner.

The design department for improvement, in the PDM system design changes. The MES system will be the first time to obtain accurate design data after the change, to guide the production. Therefore, PDM system and MES system are complementary to each other, but need two to reflect the comprehensive integrated system.

Case analysis:

Next we will take a real case to analyze the customer Once PDM system and MES system yes How to integrate the.

enterprise Background:

This is a collection of R & D, production, sales and service in one of the large modern enterprise Home Furnishing, independent research and development and production of products to the furniture mainly. Companies have long attached great importance to the overall construction of information, by as early as 2008 SAP-ERP The solution, after using SOLIDWORKS   CAD/CAE/PDM overall solution , The establishment of the management platform based on 3D digital design , In order to solve the problem of the information system data source .

In terms of MES, enterprises have also done research and exploration very much, at present in the manufacturing sector has been widely used.

enterprise The application of PDM system:

The enterprise through the SOLIDWORKS PDM will manage to design data generated throughout the design process of product development. .

The R & D department will product appearance design, through standardized audit, make preparation of structure design and basic process by the structure design department, three-dimensional design by SOLIDWORKS, the formation of product 3D model, and making parts of Engineering drawings.

The final formation of product BOM and assembly models, drawings, parts processing process card etc.. To pay for package design by packaging design, the formation of sub model, B packaging OM , Hardware package drawings , Packing list and other design data . Finally, by the personnel quota data , Production of the final product Fixed BOM and preparation process.

In the SOLIDWORKS PDM , The establishment of standardized document management structure , According to the enterprise standard , Unified all the design data set classification storage , The convenience of information system in the future to call these data .

adopt P The process module of DM , To process the design of each component , The process information is stored in the PDM database.

The MES system call P DM Data:

PDM system design data standard management in unified electronic warehouse, other information systems can be based on a variety of file system requirements in a convenient PDM.

about M ES system , Need to perform SAP system issued a production order. In the production order may contain parts machining parts number, and other information processing. Processing drawings, process MES system call parts operation instructions and other information to the station terminal display, so as to guide the workers in manufacturing. MES system through the PDM interface to access these data.

SOLIDWORKS PDM is open API interface, through the component number information list, can PDM fast search The corresponding engineering drawings, engineering drawings and the local view is loaded into the server, workstation machine MES client through the URL address can be loaded with engineering drawings, field workers can see the drawings.

Work instruction process card and the corresponding attribute of the operation had been recorded in the P DM database . MES can directly query the corresponding data table in the PDM database, and then loaded into the MES client.

Summary:

With the continuous development of market environment and information technology, the enterprise of The MES system will be more and more obvious, there will be more and more enterprises choose MES system. However, whether ERP or MES system, to achieve their value better, must provide accurate and complete, and only real-time data for its products.

Therefore, enterprises must first through the PDM system will manage to produce the required data source design specification, and then through the system integration, automatic transmission accurate specification data to the MES system, in order to protect the MES play a greater role.
