Background and Motivation
Simmod GUI applications do not cover the complete workflow
Manual tasks cost time:
backing up
documenting changes
Working in a team requires copying complete application
No Undo functionality available
Backup copies take up a lot of space

Slide 2 > Extensible Workflow Management for Simmod > Alexander Scharnweber
October 30, 2008
Background and Motivation
Numerous different analysis tools in use
Excel
Access
Stand-alone tools written in different programming languages
No documentation
No structured software development for tools
No peer review for algorithms

Extensible Workflow Management for Simmod (EWMS)
Workflow Wrapper for Simmod Engine and GUI applications
Prototype developed as diploma thesis
Ongoing further development within DLR
Will cover as much of the simulation workflow as possibleVersioning and BackupTeamworkSimulation ExecutionSimulation Documentation as required by QMSAnalysis and Reporting

Versioning
Complete Application stored in a Subversion repository
After each simulation run, modified files are committed to the repository
Metadata available:
User Name
Date and Time
Simmod version
Comment
All previous versions available at any time

Backup and Teamwork
Daily backup for repository server
Backup copies take up no space on workstation
No manual backup necessary
Subversion only stores modified files, not entire applications
All Simmod users can access repository to retrieve applications
Access Control available for individual applications

Analysis and Reporting
Built-in database stores relevant input and output files
API Framework provides access to:
application files
database
Analysis and Reporting Modules access information via API
Modules implemented in Java
File System access
Individual User Interface

Database
Built-in SQL database (HSQLDB)
Memory-based tables for speed
Import parsers for DBF files and SIMU26
Configurable SIMU26 import to allow for future extensions
Data access via SQL queries
Supports several concurrent application revisions

Extensibility
Modules can be activated at runtime
Each module is essentially an independent Java program presented as a Tab in the main interface
Common filter panel provides detailed filtering of simulation output
Documentation and Source Code available
Peer Review of underlying algorithms

Planned Extensions
Performance Indicators
Separations
Comparative Analyses
compare different revisions of an application
Direct connection to real-time simulation
...
