基于多约束非线形模型的航路优化研究

当飞行计划所规定的航线通过飞行受限区域时,尽量合理地安排飞行计划是空中交通管理的首要目的。文章以最小化成本为目的,首先建立一种多约束非线全局飞行安排模型,此模型综合考虑了当前航班和后续航班的操作成本;然后针对此模型文中提出了一种改进的启发式算法,此算法在常规启发式算法的基础上引入优先级别表,用优先级别表调控优化结果;最后,通过仿真说明此算法的有效性和可用性。

Improving Airspace Flow Management Using a Multi-Constraint Nonlinear Model

In the full paper,we explain our improvement in some detail;in this abstract,we just add some pertinent remarks to naming the first two sections in the full paper.Section 1 is:mathematical modeling.In this section,we construct the multi-constraint nonlinear model,in which we use an objective function to minimize the operating cost of both current flight flow and succeeding flight flow.What is special for our model is that it has the second category cost attributes in addition to the first category cost attributes.Section 2 is:improving the normal heuristic algorithm.In this section,we improve it by bringing in a priority list,whose rules are shown in Table 1.We give a numerical example in section 3 to show that our improvement is feasible.Finally we perform numerical simulations,whose results are given in Table 4.The analysis of the simulation results shows preliminarily that our improvement is effective.
