<< Back to Models and Simulation Capabilities

AIRMM uses a top-down design starting with the primary need to enhance the decision process and available knowledge relative to policy-making. AIRMM utilizes available state-of-the-art technologies from DOD, industry, and academia. AIRMM will provide an integrated modeling environment that minimizes complexity and ambiguity of the needed decisions.

The main components of AIRMM include;

• The Knowledge Formulation and Analysis Environment which supports the formulation, capturing, and abstraction of aviation knowledge. Included in the Knowledge Formulation and Analysis Environment are systems to capture and manage aviation knowledge from domain experts, simulation exercises, and operational data. A domain specific Ontology will allow for the reuse of domain knowledge and the sharing of common understanding of the domain.
• Extendable Frameworks for Knowledge, Model/Behavior, and Use Cases. The Knowledge Framework provides a way to organize knowledge relative to the aviation domain and the analytical model base. The Model/Behavior Framework provides a formalized mapping of aviation domain behaviors to an existing model base and is used to capture behavior of the modeling components. The Use Case Framework provides a standardized representation of modeling scenarios for modeling the aviation domain.
• DOD's Technical Framework for Modeling and Simulation which incorporates a suite of formal object-oriented methods, interfaces, freely available tools and high-performance services for distributed simulation.
• Repositories for Software Components and Tools. Through the use of reusable components, developers can quickly provide enhancements concentrating on new aviation behavior without using resources for developing existing aviation behaviors.

Summary

The first step toward the AIRMM vision is a prototype to investigate basic feasibility. A number of selected simulation models and components are being connected using High Level Architecture (HLA) Run-Time Infrastructure (RTI) software, web application techniques, and other communication techniques to emulate a limited gate-to-gate simulation environment. A limited knowledge base will be developed centered on operational knowledge.

The evolution of AIRMM will incorporate ongoing activities by NAS Architecture groups, the Aviation Information modeling community, and various aviation related standards organizations. Validated NAS representations will eventually form the basis of AIRMM's long-term integrated decision/knowledge environment that supports concept validation.

AIRMM's benefits include:

• A dynamic lessons learned capability
• More accurate and valid knowledge of the concept under validation
• The formal capturing of model behavior and fidelity
• A standardized information representation
• Support for a scalable modeling environment
• The ability for model and tool developers to integrate into a system with less time and cost
• Leverage knowledge gained from previous simulation studies
• The ability to test and evaluate future air traffic tool prototypes.
• AIRMM presents one possible integrated environment to forward aviation concepts and the aviation modeling industry. AIRMM attempts to capture a comprehensive vision to strive forward, utilizing existing and maturing technologies that many organizations are already attempting to adopt in a piece-meal fashion. The use of existing and maturing technologies provides a cost-effective means in helping to define AIRMM system.
