A New Graph Representation of Assembly Planning
نویسندگان
چکیده
To express nonlinear assembly sequences, a logical tree model for assembly sequences planning is proposed after analyzing the disadvantage of the existing method to generate and express of assembly sequence. Meanwhile, based on the information of the function structure tree and its parts and components of the production, the broad sense sub-assembly is identified by dividing the assembly relation graph and matching the rule. So, the identification of broad sense sub-assembly is simplified. Then, the preferential constraint relation of parts of broad sense sub-assembly is judged by matching assembly knowledge. Finally, based on the function structure tree, the data node and the relation node are continually added. From the top layer to the bottom layer, the tree for expressing assembly sequences is created in turn.
