NASPAC 2.0 Requirements
NASPAC 2.0 Architecture

3. Introduction to NASPAC
National Airspace System Performance Analysis Capability (NASPAC)
System wide discrete event Simulation tool
Purpose
Tool to aid in designing, developing, and managing the National Airspace System
Cost benefit analysis
Why NASPAC?
SPEED!
Takes less than 10 minutes to model one day

4. NASPAC Architecture - Current

5. NASPAC Architecture – Current (simplified)

6. NASPAC 2.0 – Requirements Reduce complexity
Preprocessing
Deployment
Post-processing
Maintenance
Support dynamic events - generic software agents that can change model conditions during runtime based on pre-defined rules
Trajectory modeling, rerouting and cancellations
Model dynamic weather
Introduce geometry into SIM (spatial calculations)
Support multi-pass GDPs
Dynamic sectorization
Support Monte Carlo Simulation or Batch runs
Bring schedule generation and trimming into NASPAC
Data management
Input files – inputs bounds and consistency check
Provide output data analysis
Output files – Graphical display of outputs
Testing and Validation
Automate testing and validation
Speed of execution

7. NASPAC 2.0 Architecture (proposed)

8. NASPAC 2.0 – Architecture …
Description
Port all pre and post processors to Java
Component based architecture (jars as plug-ins)
Use JNI to transfer data between Sim Core and Java or use a java based simulation package
Provide reporting tools for output data analysis
Provide GUI to run and manage batch processing
Advantages
Ease of development in java for data preparation, and pre and post processing
Allows seamless communication between all the components providing a feedback mechanism
Challenges
SimScript language does not support JNI interface
Java based simulation packages are not scaling too well (threading and memory issues)
Bring schedule generation within NASPAC
