摘要: 针对飞机装配过程中装配工位物料需求时间模糊化现象,提出基于正态模糊时间窗约束的工位物料需求时间参数表征方法,用正态模糊数的隶属度表示工位的满意度。建立了基于正态模糊时间窗约束的飞机装配物料配送路径规划数学模型,并采用遗传算法进行了求解。遗传算法的选择算子利用轮盘赌和最优保留策略,交叉算子采取小生境选择机制的双选择交叉策略,变异算子确保每代个体得到进化。MATLAB仿真结果表明,该规划方法拥有较好的经济效益。

Abstract: Required time of assembly position material requirements was fuzzy during aircraft assembly. A time parameterization method for work station material demands was proposed based on normal fuzzy time window constraints. The membership degree of normal fuzzy numbers was used to represent the satisfaction of stations. Based on the presented normal fuzzy time window constraints, a mathematical model of path planning was established for aircraft assembly material delivery. The presented mathematical model was solved by genetic algorithm. During solution, roulette and best reservation strategy were used as selection operator. Niche selection mechanism of double selection crossover strategy was used as crossover operator, and mutation operator was used to achieve better solutions. MATLAB simulation results show that the presented path planning method has better economic performance.

Key words: aircraft assembly, material delivery, normal fuzzy number, path planning
