Because of space limitations, this section briefly reviews OR applications in airport airside operations and air traffic flow management—only two of the four major areas identified above. Surveys of OR models for the analysis of passenger terminal operations can be found in Tosic (1992) and de Neufville and Odoni (2003). Of the many OR-related topics addressed by research on air traffic control, the widely investigated subject of detecting and resolving potential “conflicts” between airborne aircraft is reviewed well in Kuchar and Yang (2000). Various other analytical and simulation models on several different aspects of ATC are covered in Odoni et al. (1997).
