                    Abstract:In  response  to  the  frequent  occurrence  of  cable  harness  faults  due  to  unreasonable  section  design,  a
                    method for optimizing the layout design and simulating the verification of flexible cable harness sections is pro⁃
                    posed. This study establishes a physical model of cable harness section layout pattern and utilizes a combination
                    strategy of multi-neighborhood operators and simulated annealing algorithm. New neighborhoods are generated by
                    combining  neighborhood  operators  according  to  the  combination  strategy.  After  multiple  iterations  and  searches
                    with the simulated annealing algorithm, the optimal solution is output based on the annealing function with a cer⁃
                    tain probability, obtaining the final layout after global optimization. Finally, simulation verification is conducted
                    on cable harness examples, demonstrating the method's good performance and effectiveness in solving the prob⁃
                    lem of section layout. The computational complexity of the algorithm is relatively low, enabling efficient solution
                    in  practical  applications.  It  holds  practical  significance  in  the  design  and  on-site  construction  of  secondary  cable
                    flexible harnesses.
