M&S and Interoperability
M&S Interoperability - The ability of a model or simulation to provide
services to and accept services from other models and simulations, and
to use the services so exchanged to enable them to operate effectively
together.
(US DoD definition)

HLA 1.3 vs HLA IEEE 1516
HLA 1.3
„
US DoD standard
„
Open international standard
„
Developed using SISO processes
„
Developed using IEEE processes
„
Mainly used for defence applications
„
No Pay - No Play policy enforced by
DoD
„
RTI verification provided by DMSO
„
Federate Compliance Testing
provided by US and France
„
Still videly used (mainly in the US)
„
DMSO RTI no longer available for
free
„
Several verified commercial RTIs
exists
„

IEEE 1516
Several non-verified RTIs exists
„
„
Stronger requirement on standards
being verifiable
Videly used in non-defence
applications
„
Greater market acceptance
„
RTI verification provided by DMSO
„
Federate Compliance Testing
provided by US, France and Sweden
„
Videly used mainly in Europe, Asia
and US

RTI Certification
An HLA Compliant Federation requires an HLA compliant RTI and HLA compliant Federates
Certification is the proof of Compliance

RTI Certification
„
RTI Verification
„
Level 1
- Self-administered by RTI developer
- Test procedures provided by DMSO
„
Level 2
- Provided by the RTI Verification Facility
- Verifies that candidate RTIs adhere to all requirements specified in the HLA Interface
Specification.
- Approx. 1900 Tests
- Successful level 2 verification required for certification
„
Verification based on
„
HLA specification version (1.3 or IEEE 1516)
„
Interpretation
- DoD Interpretations document for the HLA Interface Specification, Version 1.3: Release 3
- DoD Interpretations of the IEEE 1516-2000 series of standards

Benefits of Certification
„
Certification is a proof of compliance
„
„
Certification is a proof of commitment
„
„
„
Required by most VV&A processes
Certification is the cornerstone for interoperability and reuse
„
Standard compliant infrastructure and compliant use of infrastructure provides the
basis for technical and syntactic interoperability
„
Standard formats for describing Information Exchange is the basis for semantic
interoperability
Certification gives a good signal to the market
„
13
Certification process shows the developer’s commitment to the standard
Certification is an important part of quality assurance
„
„
A HLA compliant federation requires compliant RTI and Federates
e.g. DMSO RTI Verification Status Board

Summary
„
HLA is a standard focused on technical, syntactic and parts of semantic
interoperability
„
The open international IEEE version of HLA promotes a wider use of the
standard allowing
„
HLA IEEE-2006 ”HLA Evolved” provides enhancements, new features
and new services that will increase interoperability
„
Certification available for RTI and Federate compliance
„
Certification is a cornerstone for interoperability
