Data compilation and analysis, –
IZMIR, 1-2 APRIL

2. OVERALL OBJECTIVE Compilation, analysis, and processing
OPTIMA - WP 04 - Techno-economic data – INTERGEO
OVERALL OBJECTIVE
Compilation, analysis, and processing
of TECHNO-ECONOMIC DATA
The basis for OPTIMIZATION

3. OPTIMIZATION Demand and supply nodes in WaterWare
OPTIMA - WP 04 - Techno-economic data – INTERGEO
OPTIMIZATION
Demand and supply nodes in WaterWare
will incorporate the proposed water technologies
including parameters for the optimization
Possibly a developed pre-processor
will translate the database information
into parameters the WaterWare model can use
Database will describe
alternative water technologies, their costs and efficiencies,
that the optimization algorithms
can configure to meet constraints and maximize/minimize/ objectives

4. OPTIMIZATION OPTIMA - WP 04 - Techno-economic data – INTERGEO
• Choice of water technologies of different costs vs
performance
• Examine different allocation strategies to improve overall efficiency, growing demand etc
MEANING multi-criteria OPTIMIZATION
Maximize • Supply/demand ratio (by sector)
• Reliability (% time, volume),
• Efficiency,
• Benefit/cost ratio
CONDITION : meet the constraints
(minimum or maximum allowable levels of selected criteria
Eg. water quality, economic efficiency etc)

5. WATER TECHNOLOGIES CLASSES
OPTIMA - WP 04 - Techno-economic data – INTERGEO
WATER TECHNOLOGIES CLASSES
STRUCTURES: Node structures in WaterWare
DEMAND MANAGEMENT: a technology at a cost, we can satisfy the same useful demand with less water
3. SUPPLY MANAGEMENT: this basically includes all technologies that reduce water losses
4. ALTERNATIVE ALLOCATION: not directly be associated with a specific water technology: it simply modifies the rules of water allocation to different users, e.g., reservoir release rules, diversion rules and priorities.
5. QUALITY MANAGEMENT: the first release of the WaterWare optimization system does not include water quality internal to the optimization procedure; water quality will initially be treated as a constraint.

6. DATA BASE DEVELOPMENT STEPS
OPTIMA - WP 04 - Techno-economic data – INTERGEO
DATA BASE DEVELOPMENT
STEPS
INITIAL APPROACH regarding database structure / Start with a subset proposition about the structure-fields-representation
Begin Compile/Organise GENERIC INFORMATION / Looking into WATER SAVING MEASURES
Develop few EXAMPLES as a start
Set up an on-line data base that can be used through the web
Allow partners to enter some case specific data to the examples provided
Database structure evolution / Define a good representation structure to be in agreement with the model
7. Filling up – completing the database

7. EXCEL sheet - DATA FORMAT

OPTIMA - WP 04 - Techno-economic data – INTERGEO
GENERAL COMMENTS
Huge amount of information
Need simplifications / assumptions
We can provide indication of cost/SIZE of every measure,
which may need to be ADJUSTED for each specific case
Cost equations can be found in the bibliography
