IQEM: Products and Services
One example of the functions developed in the IQEM project is
the embedded Safety Reporting and Safety Management in RiskWare:
The main tool used here is the RTXPS
real-time hybrid expert system, that combines a
real-time (time-ware) forward-chaining command and control module
with a classical backward chaining problem solving capability.

Objectives and Mission:
RiskWare is a management information and decision support system for technological
risk assessment and management. The system is designed to support the implementation
of the Directive 96/82/EC of December 1996 (Seveso II) and related national legislation.
Risk analysis and the management of safety reports and safety analyses in a
dynamic, multi-media (hypermedia) document, that integrates data bases, text, GIS,
CAD, graphics and imagery, and a dynamic expert system as well as interactive
emergency simulation models (release, fire, explosion, dispersion, soil/water
Real-time decision support for emergency management, with rule-based processing
of emergency plans and dynamic simulation and forecasting of impacts;
Training applications for risk assessment and management, using simulation of
emergencies combined with didactic multi-media material, tests.
Improved and more efficient Risk Management through:
- Integration of Risk Analysis and Risk Management
- Integration of all available information resources
- Integration of legacy data and tools
- Improved risk analysis with state-of-the-art stochastic simulation models
- Automation of complex tasks in risk assessment
- Decision support with a rule-based expert system
- Improved documentation and communication, compliant with European and national
legislation and technical norms
- Improved access to relevant information (search functions, Intranet)
- Efficient maintenance and update of the information
- Improved data quality through automatic consistency checking
- Multiple use of the data bases
- Consistent and up-to-date information for all users
- Modular design, flexible fully data driven configuration, multi-language support.
RiskWare supports a consistent compilation and efficient maintenance of all risk relevant
information in different formats into one common but modular system; RiskWare makes it
possible to check consistency, plausibility, completeness, and currentness of the data
basis with formal methods. The system provides fast retrieval and interpretation of data,
and tools for complex analysis and simulation, but at the same time is easy to use and
offers intuitively understandable user interface with multi-media formats.
RiskWare supports the development and management of saftey reports and alarm
plans (96/82/EC Art. 5) and in particular Art. 7, 9 (Safety Reports) and 11 (Alarm
Plans). It provides tools for the simulation of accident scenarios, as well as for public
information (Art. 13, 1,4)
The simulation models, embedded in a command-and-control expert system, can be
used for decision support for real-time emergency management, as well as training
The modular system can be easily extended with optional components for
environmental monitoring, data analysis, and modeling for normal operating conditions,
and can address problems of hazardous material transportation.
RiskWare base system:
Management of Safety Reports and Emergency Plans:
Following Seveso II and national regulations (e.g., ÖNORM A 9030) in a relational data
base and XML/HTML format for easy data management and exchange between
enterprises (domino effects) and enterprise and competent authorities as well as
external rescue services;
Integration of simulated emergency scenarios;
Design, analysis, simulation and documentation of incident scenarios, safety
measures, and emergency plans, e.g., in the form of event trees.
Models describe release, fire, explosion, atmospheric dispersion, infiltration, water
bodies, including several dynamic models (3-D wind field and FD dispersion model for
near-field simulation with building obstacles); models use an embedded GIS for the
display and animation of dynamic simulation results.
Simulation of domino effects through the cascading of models by the expert system.
Simulation results can be directly and interactively integrated into the safety reports
Real-time decision support for emergency management:
Processing of emergency plans including forecasting models and the external communi-
cation management is controlled by a rule-based real-time expert system.
Probabilistic Risk Analysis
Simulation with Monte Carlo methods is based on frequency/probability distributions of
source terms and weather parameters.
Optional components and functions:
Export of (parts of) the data (safety reports, external emergency plans) with a web
server (public information) or to the competent authorities.
Support for environmental monitoring, data analysis, simulation of emission under
normal operating conditions, real-time continuous simulation, forecasts.
Optional models for noise and groundwater quality
Technical training applications for distance learning (Intra/Internet)
RiskWare is available as a client-server system for Linux and UNIX servers and PC
clients; we offer continuing support and maintenance through the Internet or dedicated
RiskWare can be used, in part (e.g., for complex simulation models) or in its entirety, as
an application service over secure Internet or dedicated peer-to-peer connections.
