Abstract | Instead of assigning 3D trajectories of the flights in some sectors under traditional Air Traffic Management (ATM), the Route Network Flow Assignment (RNFA) problem is redefined in the new generation of aviation. It needs to properly assign both the 3D trajectories and the time slots (4D trajectories) for all the flights in the whole airspace, aiming at maximizing the use of airspace and alleviating the air traffic congestion. It is an optimization problem in essence and has to optimize all the flights' 4D trajectories. This problem is challenging because of the large scale of the flights and the relativity among them. To deal with it, this paper puts forward an effective method. The main idea is to introduce a divide-and-conquer strategy to divide this large scale problem into small ones. During which, a dynamic grouping operator is adopted, while considering the relativity among the flights. For the optimization of the subcomponents, a dual coding Differential Evolution (DE) method is proposed to adapt the high efficiency DE to this discrete optimization problem. The experimental results show that our method can solve the RNFA problem both effectively and efficiently and outperforms the current approaches. Moreover, the application of the proposed methodology can also be served as a benchmark application in the fields of the large scale problems' optimization. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
