A computerized method has been developed that takes operating rules and traffic data and transforms them into theoretical concepts. These concepts are characterized by two indices—decentralization and compactness. The degree of decentralization is a measure of how efficiently space is used while the amount of compactness is a measure of convenient circulation, particularly for transferring passengers. Some 66 of the world's air terminals were represented by these two indices and placed in a catalog of concepts. With the theoretical pair of indices a designer can match these with a pair of indices of an actual terminal concept. This is done in a matrix of indices where the cells of the matrix are keyed to the terminals in the catalog of concepts. The selected concept can then be used to start the designer on the right track to the optimum concept.
