The invention discloses a mixed assembly sequence generation method based on symbols. The method comprises steps of establishing a ZBDD expression of a connection matrix and an interference matrix according to the connection matrix and the interference matrix of an assembly; solving a precedence relation matrix in dependence on the interference matrix of the assembly; searching all feasible assembly sequences, establishing a file for storing the feasible assembly sequences and subassemblies generated in the assembly process, and establishing a dynamic array for storing path numbers for generating the subassemblies; and refining the established file for storing the feasible assembly sequences and the subassemblies, and deleting dead states in the assembly process. The invention can ensure completeness of assembly sequences by analyzing all possible assembly operations at the high space and time efficiency, ensure reliability of the assembly sequences by determining local assembly geometric feasibility, ensure
