Abstract:This paper proposes a collaborative decision framework for departure sequencing,which can remedy the defect of air transportation automation system and make it come true that scheduling departure aircraft automatically under air transportation departments' collaborative decision-making of flight data,assisting controllers for take-off scheduling decision.A general framework of collaborative decision taking off scheduling system is proposed.The details of framework that include the flow work of system,core module structure design,the constraint conditions of flight departure and the scheduling algorithm of the automatic take-off are described.User permissions are determined by their roles and responsibilities,who can participate in information sharing and flight data collaborative decision making.In addition,the framework adopts automatical departure scheduling algorithm with wake stream and air flow constrains which is designed by rolling horizon procedure,getting the optimized flight sequence to take off,the time slot table being used to display the flight sequence to the user directly.Finally,the actual operation situation of the system shows that the system can complete the multi-user cooperative decision-making,realize the automation of flight management and provide the basis for ATC decision.
