Overview
• Multiple criteria in Water Resource Risk
Management
• Interactive Decision Maps
– Russian method
• LP to generate alternatives
• Visualize more than three criteria
– Useful for problems with many potential
variants

Complications related to old approaches:
example of water quality planning —
cost (F) versus oil products pollution (Z5)
Feasible Goals Method (FGM) /
Interactive Decision Maps (IDM)
technique
The FGM/IDM is a graphic form of the
goal approach. Its main features are:
• approximation of the Edgeworth-Pareto
Hull (EPH), i.e. the variety of feasible
goals and all dominated criterion points;

Water quality to be improved in a large river
basin
DSS to support the search for reasonable
strategies of investment in wastewater
treatment facilities
Consider both cost and its allocation between
regions
Climate, Water and Ecosystems - Oct 2011
 DSS calibrated for the Oka River
 One of the largest tributaries of the Volga River
 Seven regions are located at the main flow of the river
 The river-bed was split into fourteen segments that are
related to the locations of the regions
 Six most important pollutants
 Suspension
 Phosphates
 Nitrates
 Oil products
 Ferrous combinations
 Biological oxygen demand

• Users apply the DSS for the search for preferable
investment strategies
• A large list of performance indicators is provided
to users
– They can specify screening criteria directly in the list
– Two kinds of potential criteria
environmental indicators - describe resulting
pollutant concentrations in a region or in the river
economic indicators - include the total cost of the
project and investments in particular regions
Climate, Water and Ecosystems - Oct 2011
DSS allows user to specify two to
seven performance indicators
from the list to be the screening
criteria. Constraints on the
indicator values can be imposed.
Here the total cost of the
project, the investment in the
fourth region and the
investment in the seventh
region have been already
specified to be screening
criteria.
After criteria were specified,
computer approximates the
Edgeworth-Pareto Hull (EPH),
which is contains all feasible
combinations of the criterion
values and all criterion points
dominated by them.
Usually user desires to explore
three criteria at once:
he/she explores decision maps
Climate, Water and Ecosystems - Oct 2011
To explore dependencies
between more than three
criteria, user can animate the
decision map or use
matrices of decision maps
(snap-shots of decision map
animation)
Climate, Water and Ecosystems - Oct 2011
Then, user selects one of the
decision maps and selects the
preferred goal
(cross in the following picture)

Conclusions
• Water resource management involves many
tradeoffs
• Many criteria could be considered
• US Federal Gov’t tends to focus on costbenefit
– Water resources agencies in the past mandated
multiple criteria
• Lotov’s IDM offers an interesting means to
visualize tradeoffs
