Abstract: The process model with complex structure in the existing process library is not easy to manage and understand,the indexing efficiency is low.To address these problems,a process model massive model retrieval method that supports complex structures was proposed.Aiming at the storage of process massive process model and the multidimensional indexing problem of efficient process model,the method of transforming the general process model with complex structure into the block-based process model using flower model was proposed,which could be used to generate the index of the general process model.The block-based process model was used to generate the corresponding process tree for storage,and then the process tree editing distance was used to calculate the similarity of the process tree,thus the process model could be managed effectively.By constructing the corresponding cases and prototype systems,the accuracy and feasibility of the proposed method was verified in model conversion,storage and retrieval.
