The Key Technologies Of Collaborative Flow Management In Airport Terminal Area

With increasingly development of air transport industry, it is bound to cause rapid growth of air traffic flow; it will highlight the contradiction between the sharp increase of demand and the relatively decrease of supply, as well as the contradiction between airspace managers and its users. So running CDM mechanisms in ATFM is a necessity for building harmonious ATM in China. Since airport terminal area is the bottleneck of ATM, the importance to research key technologies in CDM is self-evident.In this dissertation, the status quo, development trend and the latest research results of collaborative flow management are summarized comprehensively; the relevant theoretical foundation, classical methods and main research results are analyzed deeply; the main research content, key issues and future trends of the theory in airport terminal area are dissertated systematically.The dissertation pursues a systemic research on the balance problems between supply and demand, it puts forward the concept of collaborative allocating capability and flow, and presents optimization models based on multi-restrict constraints for single airport terminal area and multi-airport terminal area. Since the arrivals and departures are two interdependent processes in most of airport, it builds collaborative optimization models of allocating capability-flow based on arrival-departure capability trade-offs and dynamic characteristics. The results show that these proposed models can provide optimal allocating schemes of capacity and flow with airline's preferences, increase effectiveness and autonomy.The slot allocation problems are studied at great length in CDM GDP, optimization models are proposed based on the principle of Effectiveness-Efficiency-Equity (3E) in single airport and multi-airport, and some indexes are also introduced to evaluate equity among airlines. According to the resource allocation principles in Chinese society, a single-objective optimization model and multi-objective optimization model are built based on 3E principle under CDM mechanism. These models are able to make best use of limited resources, minimize the total delay cost and balance it among airlines. Taking dynamic capacity and the relativity of arrival-departure into account, an Arrival-Departure GDP (ADGDP) and Multi-Airport GDP (MAGDP) in CDM are presented, the corresponding optimization model are built to collaboratively allocate airport capability and slot resources.The slot exchange problems are also studied deeply in CDM GDP, a dynamic slot trading mechanism and strategy are presented based on MAS coordination. Learning from SCS and a market mechanism, a slot trading mechanism with conditional auction is proposed. It uses unilateral payment form to implement transactions, expresses airlines'autonomous decision-making by utility, and builds a coordination trading reasoning strategy for AOC Agent based on BDI. Simulation results show that it can raise the autonomy, coordination and applicability of slot exchange in CDM GDP. Corresponding MAS coordination trading models are built for both simple exchange and complex exchange problems.The dissertation pursues an in-depth research on aircraft scheduling problem (ASP), puts forward a collaborative aircraft scheduling strategy, and proposes a priority-based optimization model and a multi-objection optimization model with the interests of ATC, airports and airlines. The priority-based optimization model is capable of transferring one flight's delay to another by priority so as to make intramural decision for airlines; the multi-objection optimization model is able to ensure safety, minimize the total delay cost and balance it among airlines, and minimize ATC workload.The dissertation also summarily proposes the architecture and framework of collaborative flow management system in China, and preliminarily designs a system based on MAS with proposed key problems in airport terminal area, these can provide reference and support for next R & D.In the end, the dissertation summarizes the main research and outlooks for further study.In a word, the dissertation's researches not only consummate flow management theory and methods in airport terminal area, but also have some guiding significance to policymakers in practical application.
