RTXPS is a real-time expert system environment designed for
on-line dynamic decision support, mission critical
command, control and communication tasks such as
- Complex operational control and assessment tasks, real-time
process control and non-linear dynamic, distributed optimization (SCADA), such as
cascading reservoir and irrigation system management,
- Real-time air quality assessment and management, including CEMS and PEMS;
- Emergency management for technological and environmental hazards,
including early warning for events such as floods, toxic or oil spills,
land slides, dust storms, etc.
including the coordination of first response, recovery, restoration and clean-up operations;
- Technical/academic teaching and training applications.
RTXPS can be configured to implement any
or operating manual based procedure or protocol.
It offers context sensitive support functions
based on Artificial Intelligence technology,
that can handle the most demanding dynamic
situations in distributed client-server environments,
with several parallel action threads. RTXPS provides
extensive support and assistance to the operator, and
keeps complete real-time logs for quality control,
but also machine learning and CBR tools.
The dynamic KnowledgeBase of RTXPS is open to asynchronous
signals from any number of processes or sensors.
Setting and querying of timers or the pending of ACTIONS
provide additional features for real-time control.
ACTIONS triggered by RTXPS include any arbitrary complex
local or remote function or model, and the inference engine
can also use a backward chainging subsystem.
For a summary description, see:
RTXPS is based on a time-aware forward chaining
inference engine, that processes context sensitive
Production Rules that manage
the dynamic problem knowledge base and trigger ACTIONS.
An independent Watchdog process ensures mission
critical reliability, and can run an independent instance for
ACTIONS are communicated to the operator in
and can automatically trigger a wide range of
functions including data entry and display,
an embedded backward-chaining expert system,
and complex simulation and optimisation modeling
and GIS applications.
Support of extensive documentation, logging,
reporting and external communication functions such
as automatic compilation and sending of e-mail or fax messages
as well as the automatic generation and update of web pages
for public information access are important features of the system.
RTXPS can run as an "embedded process", but also in an interactive (web based)
interface under direct user control.
RTXPS can also link to on-line monitoring
and data acquisition systems that can provide real-time
intelligence and feed-back from the field; this can be used not only
to update the problem context dynamically, but also for the re-calibration
of dynamic forecasting models.
|RTXPS uses a simple near-natural language syntax for its
Rules, ACTIONS and Descriptors, the variables that the Rules
operate on. An intuitive SCRIPT language supports the efficient development of
the Knowledge Base for a new application.
