description:

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 interactive workshop.

Presenter:

Zheng Yi Wu, Ph.D, Bentley Systems, Haestad Methods Solution Center, USA.

Topics:

1.      Brief presentation on GA optimization for water distribution system (30~40 minutes)

a.      Genetic Algorithm basics

b.      Least cost optimization model

c.      Maximum benefit optimization model

d.      Cost-benefit optimization model

2.      Optimization modeling tool (1 hour)

a.      Optimization modeling basics

b.      Benchmark problems including five examples from literatures

3.      Interactive Tutorial (40 minutes)

a.      Excises on single objective (cost or benefit) optimal designb.      Excises on multi-objective (cost-benefit tradeoff) design

4.      Practical optimization (1 hour)

a.      Real system optimization (e.g. tank locations, system improvement and rehabilitation)

b.      Participants are also encouraged to bring their own cases to the workshop

Fees:

$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.
