ABSTRACT
The design process of an airport terminal needs to accommodate a wide range of changes in operations and facilities. Rapid growth in air travelling requires an airport terminal to increase the capacity and to optimize the processes of in-bound and out-bound facilities. The design approach of a complex system like an airport terminal needs to recognize the relationships between the processes taking place within an airport terminal and the spaces required for the smooth and efficient execution of those activities. Previous studies on space allocation for terminal buildings considering queuing theory approach (Ma, Kleinschmidt, Fookes, & Yarlagadda, 2011) attempted to establish relationships between passenger movement and terminal space. Researchers also focused on level of service standards to provide guidelines for the amount of space per passenger (Correia & Wirasinghe, 2007; de Neufville & Odoni, 2003; Mumayiz, 1990). Some other researchers investigated space allocation techniques specifically for commercial activities (Hsu & Chao, 2005). The significance of business process models of various terminal activities, however, has not been recognized in the literature. This has rarely been used to optimize the design process of airport terminals by allocating appropriate spaces based on the business processes.
