Research And Implementation Of Flight Collaborative Decision-making System

Flight collaborative decision making system (hereinafter referred to as CDM) is a joint collaboration between the philosophy based on anexchange of information and the government and enterprises, to create more safe and more effective system environment. Through the exchange of information, all the parties involved can be coordinated to make safer and more effective decision-making, can greatly reduce the total delay of flights.Collaborative decision making system is a distributed application based on J2EE framework, application logic is divided into components, each application components according to their distribution on different machines.The use of Unix in the server cluster technology, the establishment of a ORACLE (RAC) cluster database cluster system. The cluster service in Apache, you can realize the fault-tolerant ability and dynamic load balancing characteristics of Web server cluster. The use of Spring Security security framework system; data integration using WebService receiving peripheral system data; use Active MQ to push data to other external systems, to achieve real-time interaction; WebService uses UDDI to realize the unified management.Collaborative decision making system consists of collaborative decision making subsystem and departure flight sequencing subsystem is composed of two subsystems, each subsystem is composed of severalsub modules.Implementation of the local operating units of information collaborative decision making subsystem acquisition, integration and sharing, the operation unit of each flight to form a common situational awareness.Departure flight scheduling subsystem by using the collected data, use the collation and algorithm model, calculation and calculation and departure time publish flights departing the release order, so flight operation more efficient, standardized.The main contents of this paper include:Collaborative decision making system construction scheme, function demand decision system for collaborative flight; design and implementation of decision system flight coordination; preliminary operation of airport collaborative decision making system; Standard Specification for data exchange.
