Now the wish is to materialize with a $500-mil- lion facility on the drawing board. The project is being developed by the Aviation Industry Corp. of China （AVIC）, a company involved in the production of military aircraft and information and communications technology products as well as construction of commercial airports. The artistic impressions of the airport developed by AVIC include a terminal, aircraft and other vehicle parking spaces, and a hotel. At the time of writing this, the Zambian Government was looking for over $500 million so that construction could begin on the 2,000-hectare site in a forest reserve west of the city.展开更多

This often implies that alternative flight paths have to be used by aircraft to avoid adverse weather. To reduce the impact of such path re-routes, exact techniques such as artificial potential field model and Dijkstra’s algorithms have been proposed. However, such approaches are often unsuitable for real time scenarios involving large number of waypoints and constraints. This has led to the use of metaheuristic techniques that give sub-optimal solutions in good time. In this work, an improved genetic algorithm-based technique has been proposed. The algorithm used an improved mutation operator, reduced passenger inconvenience and considered the schedules of aircraft.展开更多
