Abstract: In a cross regional and cross enterprise environment,the problem of complete assembly of complex products seriously affects the pull based production of assembly. With the support of vector database technology,the problem of complete assembly was studied using the methods of target vector and implementation vector. The vectorization of complex product assembly was studied, target vectors for complex product batches,assemblies,components,and parts were constructed,and implementation vectors based on the membership relationships of batches,assemblies,components,and parts were established. The implementation vector was formed by aggregating component vectors,aggregating component vectors for final assembly,and aggregating final assembly vectors for batches. The complete assembly rate was used to quantify the overall assembly completeness of complex products,which was transmitted from parts to components and finally to the final assembly to obtain the overall assembly completeness rate. Using the complete set rate formula,the similarity between the implementation vector and the target vector was calculated based on the batch,final assembly,component assembly,and part vector to determine whether the assembly complete set requirements were met. This intuitively quantifies the degree of complete set of components in the complex product final assembly process,as well as the gap with the assembly complete set requirements. The complete assembly of complex products is constantly iterated according to the production progress of the products,and the complete set rate is rapidly updated,effectively improving the digitalization of assembly pull based production.
