With the continuous expansion of the airline fleet and the increase of flight routes, flight dispatchers use the operation control system to exercise the functions of release and monitoring at the beginning, continuity and termination of each flight, and the energy they need to invest is greatly increased. In order to ensure the safety margin of operation control, a set of scientific evaluation system is needed to evaluate the daily workload of flight dispatchers, guide the allocation of human resources, arrange staff scheduling reasonably and optimize the system functions. According to the Advisory Circular of Civil Aviation Administration, this paper applies the recommended method and optimizes the calculation through an example of evaluating the workload of airline dispatchers. At the same time, the optimization gives a guidance of scheduling, system and process of airline operations control. The application of this method in airline scheduling can optimize resource and control the human factors risk.
