Water utilities around world are facing the
challenges of improving and expanding water systems to meet the demand.
However, the budget now is never tighter than before. ASCE 2005 survey
reports an annual shortfall of $11 billion to replace the aged water
infrastructure and the available fund is less than 10% of the total required
investment. The improvement and design solutions must be optimized to attain
the best capital efficiency. Optimization modeling proves to be effective at
enhancing solution quality and project productivity.
This workshop will be focus on practical
benefits and challenges of genetic algorithm (GA) optimization of single and
multiple objectives. Participants will be given a copy of academic version
of WaterGEMS including Darwin Designer (www.haestad.com/Darwin)
and kindly requested to bring their laptops to install the software for the
Zheng Yi Wu, Ph.D, Bentley Systems,
Methods Solution Center,
presentation on GA optimization for water distribution system (30~40
benefit optimization model
Cost-benefit optimization model
Optimization modeling tool (1 hour)
Optimization modeling basics
Benchmark problems including five examples from literatures
Tutorial (40 minutes)
single objective (cost or benefit) optimal designb.
multi-objective (cost-benefit tradeoff) design
optimization (1 hour)
optimization (e.g. tank locations, system improvement and rehabilitation)
Participants are also encouraged to bring their own cases to the workshop
$100 for each participant, it is to
compensate the cost of the workshop. In return, each participant will be
given an academic version of WaterGEMS including Darwin Designer.
