Airlines Management System in PHP

This paper presents a safety risk management model based on possibility theory to adapt and develop the Safety Management System (SMS) in airline operation control. Fuzzy sets are used to represent the key elements among crew, meteorology, weight and balance, dispatch, coordinate, and systematic operation control by risk indicators. A fuzzy integrated judgment model is also proposed, which would quantity both the possibility and necessity of the safety space. The implications of this strategy for practitioners and future work are discussed.
