Abstract:

This thesis contains an analysis of a Visually Coupled Airborne Systems Simulator VCASS and the design of the software for this system. The design is developed in three steps. First, an informal requirements definition is written to establish the viewpoint and the purpose on which the analyst bases his design. This requirements definition explains why the simulator is to be created and what it is to do. Second, a top-down strategy called structured analysis is applied to obtain a formal requirements definition. The structured analysis is presented in a blueprint-type language consisting of activity and data models. These models represent graphically the functions performed by the simulator and the information upon which those functions act. Third, a design is obtained through a structured design methodology consisting of transform analysis and transaction analysis techniques. The structure charts drawn during the analysis phase reveal system characteristics which illustrate design quality. The activity model is used to make a successful transition from a top- down analysis to a structured design which can be evaluated. The resulting simulator design, with minor revisions, satisfies the design goals established for the project. The methodologies used are highly recommended for the analysis and design of any software system.
