Research on the Assembly Sequence of a Ship Block Based on the Disassembly Interference Matrix

Reasonable optimized block assembly sequence has vital practical significance for ship construction, and the research has been done in this article at the aim of obtaining optimal assembly sequence. First, taking a double-bottom block as the object of study, by analyzing the connection relationship between each part, a disassembly network diagram and disassembly interference matrix can be generated by applying the demolition method. Based on the disassembly interference matrix, disassembly sequence can be generated according to certain rules, then the assembly sequence is the invert of disassembly sequence; next, considering comprehensively the part's physical attribute affecting the assembly sequence, the final assembly sequence can be obtained for two assembly ways using the analytic hierarchy process; lastly, DELMIA software is applied to implement the virtual simulation of the assembly process in accordance with the assembly sequence. The work of the article is of certain guidance significance to parts assembly in ship production and can lay a good foundation for realizing the ship block's digital assembly.
