摘要: 首次将遗传算法(GA)应用于飞机定检离位工作流程优化中。本文借鉴关键路线法思想建立离位工作流程多约束优化模型,根据可行解变换法思想设计编码和解码方法,并采用经过模拟退火算子和精英选择算子改进后的GA求解。仿真结果表明,在解决多约束优化问题上,改进遗传算法的最优解搜索能力较基本遗传算法有明显提高;优化后离位工作完成时间较优化前缩短14.70%,验证GA在解决定检离位工作流程优化问题上的适用性。

Abstract: Genetic algorithm (GA) is used to optimize plane’s periodic maintenance dislocation workflow firstly. The multi-limit optimization model of dislocation work is built according to critical path method (CPM), and the law of workable solutions alternation is used to design the coding and decoding means, and the GA, improved with the simulated annealing operator and the elite saving operator, is used to solve. The simulation results demonstrate that, to solve the multi-limit problem, the improved GA is much stronger in best-solution search ability than the simple GA; after optimization the finish time of dislocation work is shorter 14.70% than before, and it proves that GA is good for the optimization of dislocation periodic maintenance workflow.

Key words: GA, plane’s periodic maintenance, CPM, multi-limit optimization model, workflow optimization
