Dispatching Plan Based on Route Optimization Model Considering Random Wind for Aviation Emergency Rescue

Abstract EN

Aviation emergency rescue is an effective means of nature disaster relief that is widely used in many countries.

The dispatching plan of aviation emergency rescue guarantees the efficient implementation of this relief measure.

The conventional dispatching plan that does not consider random wind factors leads to a nonprecise quick-responsive scheme and serious safety issues.

In this study, an aviation emergency rescue framework that considers the influence of random wind at flight trajectory is proposed.

In this framework, the predicted wind information for a disaster area is updated by using unscented Kalman filtering technology.

Then, considering the practical scheduling problem of aircraft emergency rescue at present, a multiobjective model is established in this study.

An optimization model aimed at maximizing the relief supply satisfaction, rescue priority satisfaction, and minimizing total rescue flight distance is formulated.

Finally, the transport times of aircraft with and without the influence of random wind are analyzed on the basis of the data of an earthquake disaster area.

Results show that the proposed dispatching plan that considers the constraints of updated wind speed and direction is highly applicable in real operations.
