Engineering practice experience tells us, PDM in project management, rights management, process management, software packaging and process-related functions, if the design process from the internal logic of relations, is bound to form a one fragmentation "process islands", Even the static information resources, lack of timely and correct timing of the transmission line and send also the formation of "information island", resulting in a continuation of the design cycle. At ERP area, as an enterprise resource planning and management tools, business arrangements for the production process, it must be based on product manufacturing process involved in workshops, teams and groups of personnel, the current production plans, resources, equipment, occupancy, etc., as well as current production capacity to identify and implement resource allocation process must be under the company's existing stock, the market supply and demand, prices and corporate purchasing plans to form. Separate from the dynamic business operations, the same will exist "process islands" and the "information islands." In view of PDM and ERP systems have a logical link to the PDM, and ERP integration, speed of product development cycle, from the point of view, has great engineering feasibility and a very strong practical significance. In order for PDM and ERP integration, we must look for these two areas of integrated infrastructure and integration vectors. This integrated carrier must have the following two basic functions:
(1) The content covers two major areas of PDM and ERP, which is a necessary condition for system integration.
(2) Function can be removed or shielded as described in this article 2 the two areas of PDM and ERP differences between them. This is a sufficient condition for system integration.
Based on our work flow theory and technology, in combination with computer-supported cooperative work technologies and related requirements, we believe, based on computer-supported collaborative work, workflow management system can be used as integration of PDM and ERP foundation for the realization of better of PDM and ERP integration.
The reason why we will be workflow management system as the basis for integration of PDM and ERP, because the workflow technology as computer technology and automation technology, combined, in the process optimization, based on enterprise business process automation of all or part of. In the workflow management system, emphasizing the unity of the process, the system goal of consistent and dynamic process of convergence, the use of workflow management system that can effectively shield are located in areas of PDM and ERP barriers between processes, through the process of logical work together to achieve the formation of cross-cutting throughout the product (design, manufacturing areas) quasi-continuous development, and ultimately the development of global optimization system.
Based on this management philosophy, will expand the scope of the process the formation of the entire finished product, sub-process of the operation of technical support and technical conditions cover mapping product information resources, and product manufacturing resources, rather than be considered separately. For example, in the absence of PDM and ERP integration ago, the design activities in the area, due to the lack of manufacturing resource allocation, team plans, equipment, occupancy and other information, it is impossible in the design stage, from the perspective of virtual manufacturing to ensure the results of scientific rationality, The manufacturing phase of the plan to enact only the design has been completed in accordance with the results of passive carried out to optimize the degree of freedom and optimize the space is limited to a small extent, not from the perspective of agile manufacturing to optimize the design plan. However, in the workflow management system based on a unified integrated environment, the sub-process was started, the need for product geometry and product manufacturing resources logical information to be considered together, cross-referencing and coordination of such unified workflow to ensure as a process supported by information resources and manufacturing resources, unity. Objects that support the process of consistency and unity of purpose, making the analysis of the text as a separate PDM and ERP systems to dilute the distinction between the existence or ceased to exist.
In addition, workflow management systems to process the operation of the main line, from product information and manufacturing resources, two aspects of the operation of the process to support and adjustment. The workflow management system in the management of objects, that is, work processes, but also the logical constraints in the product information and products to match manufacturing resource planning, coordination, based on the optimization of the process arising from the operation of work processes carried out in the field of the main sources of information are PDM workflow to carry out the material basis for the field mainly from the ERP, while the workflow to carry out the objectives is to achieve product from concept to topology, to the physical entity conversion. Therefore, the use of workflow management system as the basis of PDM and ERP integration, on the process of unity of purpose in support of the same object on the basis of the analysis of reinforced paper the link between PDM and ERP.
Have been introduced earlier, PDM and ERP contain both dynamic and static, while the operation of the workflow itself is dynamic, and its process support an object the same time contains a static product information and manufacturing resources in the operation of the workflow dynamic , with the help of workflow management system resource distribution and sharing of the target on a consistent basis, the effective realization of the PDM and ERP between the infiltration and dialogue, expanding the areas of PDM and ERP scope, and strengthen coordination of these two areas the role of intensity. Therefore, based on workflow management system, PDM-ERP integration system with partial functional re-use, global information sharing and process characterized by unity of purpose, while the workflow management system is to ensure the systematic integration of PDM and ERP ideal intermediary, is throughout the design and manufacturing process of a unified field of activities and use of resources system bus.
Workflow Management System Based on PDM-ERP integration system will be involved in the field of PDM and ERP processes and resources (information resources and manufacturing resources) are integrated into a unified workflow management system, carried out in the workflow process, through resource share and process complement each other, dilute or eliminate the shielding between PDM and ERP. The basis for integration in the process to achieve the objectives of PDM and ERP in the management of the "intensive" of the use of workflow as a resource vector, achieved the integration of information flow and logistics, effectively expanded the scope of the role of PDM and ERP and the role of the intensity of improve the affinity of system integration.
