Abstract In the general air transportation system, air traffic controllers play a key role in maintaining a safe, orderly, and expeditious flow of air traffic. The fulfillment of this role is hindered as the complexity of controllers' workload aggravates due to various stressors. It is, therefore, the intention of this paper to address controllers’ workload stress problem by identifying the main stressors and arrive at an outranking of probable measures which can be applied at the earliest hint of such issue. The synergy of DEMATEL-ANP and PROMETHEE II approach is implemented to illustrate the decision-problem in a case study at Mactan Civil Aviation Authority of the Philippines (CAAP). The results revealed that the stressors presenting a significant contribution to the evidence of workload stress are attributed to the operational responsibilities of controllers. It then followed that compartmentalization outranked the other alternatives in reducing workload stress.
