Abstract: To deal with hybrid flow-shop scheduling problems with unrelated parallel machines, weighted encoding was used for coding operations, according to the characteristics of population update method of fruit fly optimization algorithm. Weighting coefficients were added to improve random search ability of the algorithm. The algorithm parameters were analyzed, and the optimal parameter combination was obtained. Benchmarking examples were used for simulation verification, and the effectiveness of the fruit fly optimization algorithm was verified by comparison with classical algorithms.
