Time elasticity evaluation of flight turnaround ground service process

Based on time elasticity definitions for passengers, ground staff and crew, we propose one evaluation method, which screens out airport ground service process with the maximum time elasticity for transit flight, to reduce arrival time of passengers at airports, increase the flexibility of ground services and improve the connectivity between arrivals and departures for crew. Firstly, timed delay Petri net is used to elicit all feasible service processes of one transit flight, and then the optimal service process is obtained by Analytic Hierarchy Process and fuzzy comprehensive evaluation method. Finally, one concrete example results show that the method can obtain time elasticity ranking of all feasible service processes which demonstrates its effectiveness.
