DEVS Modeling Language: DEVSML
This work is built on the JAVAML
research done by Vladimir for DEVSML. It was pursued independently by
Jose Luis Martin that resulted in DEVSML with small behavioral
support. The present work aims to integrate these two approaches and provide complete behavioral support to DEVSML by
implementing the proposed universal Atomic and Coupled DEVS schemas at Dunip. We look
forward towards standardization of these schemas with DEVS Standardization committe so that models across the
web can participate in Dynamic Modeling & Simulation over
Net-centric web services.
DEVSML is a novel way of writing DEVS models in XML language. This
DEVSML is built on JAVAML, which is infact, XML implementation of JAVA. The
current development effort of DEVSML takes its power from the
underlying JAVAML(earlier work by Vladimir) that is needed to specify
the behavior of atomic models. We now have the capability to write DEVS
models in DEVSML, both atomic and coupled through the developed DTDs.
The DEVSML models are tranformable back'n forth to java and to DEVSML.
It is an attempt to provide interoperability between various models and
create dynamic scenarios. The key concept is shown in the figure below:
Figure 1: Basic concept with respect to Automation of DEVS models using
DEVSML
Figure 2: DEVS Transparency &Net-centric Model Interoperability using DEVSML Layered Architecture
The concept shown above is based on DEVSML Layered architecture that promotes DEVS transparency. The basic concept is a part in overall web
enabled infrastructure where such atomic models are dynamically coupled and simulated over SOA. Development is underway to make the DTDs SOA
capable. The figure below shows various other acronyms like DoDAF, which is Department of Defense Architecture Framework. The present work
aims to empower DoDAF with a repository of 'interoperable' models defined under DEVS Formalism. More details on the approach can be found
in references section.
Figure 3: Process Methodology showing how automated modeling using XML can provide M&S to DoDAF documents
Finall this work is a part of the overall DEVS-DODAF Testing & Evaluation Strategy where M&S is
integrated enough to be a part of design process.
The initial concept (done in 2006) is available at DEVSML-Automation using XML for DEVS-Based Testing and Evaluation .pdf
