Evolutionary programming and aircraft trajectory optimisation


Dr. Istas Fahrurrazi Nusyirwan

The research aim is to solve flexible route planning based on a projection of demand and capacity in the airspace of Malaysia according to the Next Generation Air Transportation System (NextGen). A Performance-Based Service (PBS) approach is researched; the route planning techniques directly account for the Required Navigation Performance (RNP) of the aircraft, exploiting better equipment performance in NextGen to achieve the highest efficiency of an airport.

To study the trade space, it is necessary to compare and contrast unstructured, Free Flight approaches to structured routing approaches. Our route planning approaches are flexible in that they allow the routes to conform to the geometry of hazardous weather constraints and dynamically move with the hazardous weather constraints. Unstructured, Free Flight techniques follow a greedy algorithm for planning the most beneficial route for a given aircraft subject to weather, RNP, and aircraft conflict constraints. Flow-based route planning and tree-based route planning approaches are explored as well to understand the benefits of imposing structure in transition airspace. At the end of the research, new routes are to be suggested and new runways to cater to the projected needs.
