It further asked how this could be used to explore the best shape of airspace reservations in respect of: sensitivity to civil demand (daily and seasonal); best configuration (shape and time); and the best times to release military sectors to civil traffic (network and local level). The ESGI mathematicians developed a number of approaches that gave confidence that an airspace optimisation tool is feasible. date: 2015-03 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/706/1/Winsland.pdf identifier: Sargent, Cristina and Cawthorn, Chris and Cupples, G. and Devane, E. and Devine, M. and Holloway, C. and Klaise, J. and Mathews, J. and Nazar, F. and Olszowiec, C. and Poon, C. and Peng, G. and Van lent, J. and Walsh, E.
