and design. de Neufville and Belin (2002) studied shared-use facilities to achieve flexibility in airport operations; de Neufville and Odoni (2003) studied uncertainty; de Neufville (2008) also researched on flexibility in low-cost airports; Edwards (2005) discussed shearing layers of change in terminal design, and Chambers (2007) studied how to tackle uncertainty in airport design. Sarah Shuchi (2015) studied in detail the flexibility approach in the departure area and developed a detailed method for automatic plan generation. •
de Neufville and his co-authors (2008)
Richard de Neufville is probably the most diversified author of airport flexibility since he has several publications with different proposes. de Neufville and his co-authors identified several issues related to flexibility. Choosing an appropriate terminal configuration should be given initial priority to handle various types of passenger need, where “hybrid‟ design is highly encouraged (de Neufville, 1995). According to de Neufville and Odoni (2003), the primary flexibility in terminal buildings can be achieved by choosing an appropriate configuration that helps to expand and contract according to the activities performed. •
Brian Edwards (2000)
Brian Edwards in his book The Modern Airport Terminal discussed the importance of flexibility in airport design. According to his point of view, the need for flexibility in airport design is the result of complex interactions between airline companies, aircraft design, and airport authorities. Airport terminals are functionally turbulent spaces; different parts of an airport change at different rates. Recognizing the separate layers, as proposed by Edwards, helps in understanding the process. Each layer is on a distinct timescale so concurrent changes in each layer tend to disrupt the whole. Recognizing separate layers and allowing some disconnection between them is necessary to allow the terminal building to renew itself.
