Abstract:
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
dynamic processes.
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
Laboratory.
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.
