Research on traceability model of discrete manufacturing process information for complex products

Abstract：A complex product is complicated in its structure and production process, the process is usually discontinuous and has a large and low degree structured data. That makes it difficult to realize the traceability of manufacturing process. In this paper，a traceability unit concept was proposed, which includes product information, manufacturing resource information, production information, and execution feedback information, and data model was built with EXPRESS-G expression language. Combined with product production activities, tree-like production history information model was constructed, and the relationship between product and its manufacturing process information was created. On this basis, the top-down and bottom-up traceability of complex product manufacturing process information was realized.
