摘要
针对航空发动机燃油控制系统壳体零件专业化小流水、精益生产、工序顺序柔性等现实需求和生产特点,以尽可能确保各个壳体零件准时完工为精益调度目标,构建了带有工序顺序柔性约束的非置换流水车间提前/拖期调度优化模型;采用内嵌两段式编码和三阶段解码操作算子的改进型遗传算法进行调度模型求解;最后的实际算例验证了所提调度模型和调度方法在复杂壳体零件准时化生产方面的有效性。研究成果在汽车发动机壳体、减速器壳体、各类泵壳体等车间的精益生产与现场组织方面也具有一定的适用性和推广性。
The shell part of the aero-engine fuel control system is with the production characteristics of specialized small flow shop,lean manufacturing,operation sequence flexibility,etc.To ensure that the shell parts are completed just in time,taking the earliness/tardiness cost as the optimization objective,a non-permutation flow shop scheduling model with operation sequence flexibility was constructed.An improved genetic algorithm with embedded two-segment encoding and three-stage decoding operators was proposed for scheduling model solution.The results of the practical production cases have verified the effectiveness of the proposed scheduling model and algorithm,in addressing the just-in-time production of complex shell parts.The proposed method also has the potential to be popularized to other shell parts manufacturing fields,such as automobile engines,decelerators,pumps,etc.
