Preparing the optimal emergency response protocols by MOPSO for a real-world water distribution network

Area of Science:

• Environmental Engineering
• Water Resource Management
• Public Health

Background:

• Water security is a critical concern, vulnerable to terrorist attacks involving poisonous pollutants.
• Inadequate operational strategies can endanger entire city populations during contamination events.

Purpose of the Study:

• To develop optimal emergency response protocols for water distribution systems facing contamination threats.
• To minimize the impact of contaminant intrusion on urban water supplies.

Main Methods:

• Utilized multi-objective particle swarm optimization (MOPSO) to determine optimal emergency actions.
• Identified the strategic closure of valves and opening of hydrants as key decision variables.
• Calculated the risk associated with contaminants entering the water network.

Main Results:

• The study successfully demonstrated a method for optimizing emergency responses in water networks.
• Evaluated the effectiveness of the proposed protocols on both a benchmark and a real-world water network.

Conclusions:

• The developed MOPSO-based approach provides an effective framework for enhancing water security and emergency preparedness.
• Implementing these optimized protocols can significantly reduce the number of operational interventions, polluted nodes, and individuals exposed to contaminants.
