摘　　要：基于给出的飞机地面压力加油系统管路模型,结合模拟退火算法和单纯形法,同时利用概率突跳性搜索和基于凸多面体结构的几何搜索,提出使用高效混合优化策略计算各管路节流孔径尺寸。数值仿真研究表明,与遗传算法相比,混合策略具有效率高、优化性能好、对初值具有很强的鲁棒性、对维数具有较好的适应性等优点,大大提高了飞机地面压力加油管路节流孔优化配置的效率。According to the given aircraft ground pressure refuel system pipeline model, We can acquire the sizes of optimum orifices in all pipelines by using hybrid optimization strategy combining simulated annealing with simplex method, which simultaneously uses the probabilistic search and convex polyhedron- based geometry search. Numerical simulation results show that hybrid optimization strategy, in contrast to GA, is effective, fairly robust to initial conditions and very adaptable to the dimensions and greatly improves the efficiency of the optimum configuration of aircraft pressure refuel pipeline orifices.
