(The Anagara river)
Object of Investigation
The project was performed as a sub-contract for the State
Technical University, St. Petersburg, Russia.
The large Siberian Angara river is located at the center
of a very complex industrial and agricultural area in Russia. The
Environmental Inspection and Environmental Control Forces potentially
were able to measure 21 different types of pollutants (chemical
components) in 35 sections of the river. Also, there were objectives to
regulate the pollutant concentrations by using different cleaning
procedures and restriction of industrial waste activity from the river
The purpose of the research
was to identify pollution sources, design a pollution control and
monitoring system, and estimate the pollution side-effects.
The research team was confronted with a very complex
dynamic system that included hidden control activities. To separate the
roles of all components and to construct a realistic model was a
difficult task. Additionally, any meaningful control actions had to
comply with numerous constraints and reduce undesirable side-effects.
KET identified rules for 21 pollutants and a “dynamic
simulation model” was constructed from using these rules. It was used in
computer experiments for decision-making support. KET generated a map of
the river to identify the optimal data collection points. On the basis
of these findings, an automated environmental information system was
created. Since then, the Environmental Control system designed by KET,
is presently being used by the Environmental Control and Inspection
The major purpose for the research was to stabilize the
environmental condition in this region. Additionally, it would help
coordinate environmental protection plans for different industrial and
agricultural regions. The project results were used to organize less
expensive and more accurate system to measure activities and provide
helpful information to the Environmental Control and Inspection Centers.
How it was Accomplished
As in previous projects, an Information Analysis
Module from the KET Tool Kit was applied to a selection of essential
variables. In this case, KET was used in a more sophisticated manner
considering the research of system was essentially dynamic: in
correlation in changed of time. The dynamic variant from the
Information Analysis Module composed a list of potential side
effects to future pollution activities before the model was constructed.
An Analytical Descriptor was used for the description of the
crucial relationships between variables. KET Optimization Modules
were applied to the final generation of control schemes, which were
implemented later as parts of the Automated Environmental Control
The experience obtained in this research
project is used to analyze various dynamic systems that are not
associated with environmental problems. The same routines can be applied
to projects that have risk applications such as: the insurance,
investment fields, etc.
