Research and practice of enterprise integration supporting for fine management

On the basis of detailed analysis to information technology in engineering fields points of view about PLM vs. ERP are discussed. According to requirements of designing collaboration, data sharing and business management, an integrated platform between Pro/I and SAP-PLM is implemented as a integration case. Besides, an integration solution centered at material quota and key technologies are proposed to meet integration requirements of design, process and manufacturing in railway vehicle manufacturing enterprises, which include data integration technologies between PDM, CAPP, FastCut/Nest, ERP on the server layer; Data Pre-process technologies for design and process integration; automatic nesting optimization technologies meeting practical production requirements; the method to calculate material quota based on nesting optimized layouts; and the sharing of general NC codes. All these technologies and solutions support both innovative designing and fine management in manufacturing enterprises.
