PROBLEM STATEMENTPROBLEM STATEMENT

Even at small airports, air traffic controllers must maintain a constant awarenessEven at small airports, air traffic controllers must maintain a constant awarenessof dynamic situations. With of dynamic situations. With aircraft continuously changing locations, altitudesaircraft continuously changing locations, altitudes , and, andairspeeds, the controller must have a precise idea of exactly where each plane is and anairspeeds, the controller must have a precise idea of exactly where each plane is and anidea of where each is going in order to safely and efficiently control the flow of airidea of where each is going in order to safely and efficiently control the flow of airtraffictraffic. Any misinterpretation of a given situation may lead to a wrong decision, which. Any misinterpretation of a given situation may lead to a wrong decision, whichhas the potential for disaster. This intense workload and the demands for 100% ofhas the potential for disaster. This intense workload and the demands for 100% ofattention 100% of the time can affect the human decision-making processes. The scope ofattention 100% of the time can affect the human decision-making processes. The scope ofthis project is to create a model-based program which air traffic controllers at smallthis project is to create a model-based program which air traffic controllers at smallairports may use to track aircraft positions and to issue orders to the pilot accordingly,airports may use to track aircraft positions and to issue orders to the pilot accordingly,essentially automating the decision-making process.essentially automating the decision-making process.Consider the case of a shift-change in an air traffic Consider the case of a shift-change in an air traffic controlcontrol tower. With a tool such tower. With a tool suchas this one, the outgoing controller has entered into the program the locations of allas this one, the outgoing controller has entered into the program the locations of allaircraft currently under his or her control. When the incoming controller inherits theseaircraft currently under his or her control. When the incoming controller inherits theseaircraft, all he or she has to do is enter the next incoming pilot request into the program,aircraft, all he or she has to do is enter the next incoming pilot request into the program,which outputs appropriate action in accordance with the request. Assuming the controllerwhich outputs appropriate action in accordance with the request. Assuming the controllerissues orders according to this output, the program is updated to reflect the new currentissues orders according to this output, the program is updated to reflect the new currentsituation.situation.This paper follows the development of this This paper follows the development of this decision-making tooldecision-making tool, from the, from thegeneration and mapping of requirements, to the UML diagramming the sequences ofgeneration and mapping of requirements, to the UML diagramming the sequences ofevents, to the generation of the program code, and finally to the verification andevents, to the generation of the program code, and finally to the verification andvalidation of the decision support tool.validation of the decision support tool.

ConclusionConclusion

Thus, Decision making tool aids controller in Thus, Decision making tool aids controller in regulating the airtraffic.regulating the airtraffic.

It is this way, an system is taken analysed It is this way, an system is taken analysed and represented in UML diagrammatic way, and represented in UML diagrammatic way, and it is designed and finally implemented.and it is designed and finally implemented.
