Based on the above analysis, PDM and ERP in the management of content, processes, forms of development, the relationship between the internal operation of the system there are different degrees of difference. But, as we introduced in the previous section, as the operation of a modern enterprise is based on information flow and material flow relative to complement a dynamic system, the formation of the product cycle, two areas related to PDM and ERP, therefore, based on the complete cycle of product formation to the system point of view, PDM, and ERP in the following aspects are closely linked:
(1) process the role of causal relationship exists between the object
ERP system, the process of the role of an object, that is, the physical form of parts or products, is the process of PDM system, the role of objects (describe the product from the conceptual point of view the state of geometric or topological information) and process the role of an object of the physical manifestations of the logical relationship between the .
(2) process, logic sequences and verified the existence of the relationship between the implementation
ERP system in the production process is a sequence of PDM process sequence information generated by the logical relationship between the physical implementation and verification, ERP system, the basis of the production process optimization, as well as to determine the corresponding materials to support the theoretical basis and is managed by the PDM system, product information and a logical development of information and improve the logical route.
(3) The consistency of management objectives
PDM and ERP goals in the management of a high level of consistency, PDM and ERP While the management of the objects and the process of distinction existed, but its management goal attempts, through scientific scheduling and control, reduce errors and rework, in the shortest possible period of time, with minimal resource consumption, using the most economical means and methods to ensure that the product was first listed.
(4) Process with the support of the conditions linked congenital
Even if the distinction introduced in the previous section, we can see, the product of abstract geometric topology information, the process is carried out in the field of PDM product, but also the field of ERP process to guide the activities of the foundation and the results of verification conditions. Therefore, to strengthen the link between PDM and ERP, the product must take advantage of a unified geometric topology information associated with the process of communication.
(5) The company's products is that the sequence of the logical relationship between the two processes coupling the results of
PDM in the process sequence in accordance with the progressive refinement from the whole to the local carry out the design of the road, while the ERP in the process sequence in accordance with from the local to the overall manufacturing and assembly process to carry out, while the enterprise is the end product of these two lines from different and the process undertaken in the field coordinates in time sequence of the coupling results.
With the development of PDM and ERP, which also appeared in some of the functions of overlapping areas, such as product structure / BOM management, product components statistics and management.
