The system effectiveness of an air traffic control (ATC) center and its variation directly affect the workload of a controller and the capacity of the airspace controlled by the ATC center. They are the key operational parameters of an ATC control system. Based on an effectiveness conceptual framework of system performance and the analytic method of a system contributory model, this article presents an effectiveness analysis procedure for the system of an ATC center. A 9×50 matrix is created which characterized the behavior of the whole system and the performance deviation caused by status changes of inner and outer elements. The value of each element contributing to the whole system is calculated upon an investigation of the opinions of system specialists and controllers. And the article performs an evaluation of the system effectiveness of an operational ATC center by this model, which reveals certain distinguishing features of system effectiveness and their variation. The evaluating results show good conformity with the judgment made by operation specialists, which verify the rationality of the effectiveness contributory model of an ATC system and the analytic approach used in this article.
