Aviation System Analysis Capability Executive AssistantJames A. Villani, Logistics Management Institute; and Kevin Anderson, Ricciardi Technologies Incorporated |
The Aviation System Analysis Capability (ASAC) is a diverse collection of models, databases, analysts, and individuals from the public and private sectors brought together to work on the issues of common interest to organizations within the aviation community. With the ASAC Executive Assistant, researchers at NASA and elsewhere can quickly evaluate the economic potential of alternative technologies and systems. By linking the many distributed models and data that comprise the ASAC system, the Executive Assistant provides an intelligent interface with which the user can perform detailed analyses.
The Executive Assistant was architected, designed, and implemented using object-oriented techniques, languages, and tools. The Domain-Specific Software Architecture (DSSA) approach, a domain engineering process, was used to produce an architecture. We used CRC Card techniques, Object Modeling Technique (OMT), Design Patterns, and Universal Modeling Language (UML) to develop and document our system design. The system is implemented using CORBA standard services, C++, Java, and an ODBMS. The user interface is accessible via a web browser.
Our presentation will include a brief overview of our system as described in the preceding paragraphs. The demonstration will show how the application graphically represents mathematical and economic models of the aviation industry interconnected in a useful analysis. These models are distributed among several computers. When an analysis executes, relevant output data from a completed model are passed seamlessly to successive models. We will demonstrate how a user can create his or her own analysis scenarios by providing input values and configuring outputs. The demonstration will show how the user can set breakpoints between models and visually monitor the progress of the analysis. We will show how we manage user security and distributed access to analyses and scenarios. Within time limitations, we are prepared to discuss all technical aspects of the design and implementation of this system.
