The Dynamic Information Architecture System (DIAS) is a flexible,
extensible, object-based framework for developing and maintaining complex
multidisciplinary simulations. The DIAS infrastructure makes it feasible
to build and manipulate complex simulation scenarios in which many
thousands of objects can interact via dozens to hundreds of concurrent
The flexibility and extensibility of the DIAS software infrastructure stem
mainly from (1) the abstraction of object behaviours, (2) the encapsulation
and formalization of model functionality, and (3) the mutability of domain
object contents. DIAS simulation objects are inherently capable of highly
flexible and heterogeneous spatial realizations. Geospatial graphical
representation of DIAS simulation objects is addressed via the JeoViewer,
an object-based GIS toolkit application developed at Argonne National
DIAS simulation capabilities have been extended by inclusion of societal
process models generated by the Framework for Addressing Cooperative
Extended Transactions (FACET), another object-based framework developed at
Argonne National Laboratory. By using FACET models to implement societal
behaviours of individuals and organizations within larger DIAS-based
natural systems simulations, it has become possible to conveniently address
a broad range of issues involving interaction and feedback among natural
and societal processes.
