To vigorously promote the integration of information and industrialization, we should achieve technological breakthroughs in key fields of aerospace equipment. In the next decade, China's demand for aircraft will continue to increase, which requires aircraft parts to be manufactured with high efficiency and fast response time. But the research and application of the production line scheduling algorithm are still relatively few, which leads to the actual production line can not play the maximum efficiency. Aiming at the above problems, this paper takes the actual flexible production line as the research object, establishes the production scheduling model in line with the actual field production, and then uses the optimized particle swarm optimization algorithm to solve the model and gets the optimal solution.
