Methods for computation of performance resilience and quantum resilience for the real-time operation of water distribution systems under critical conditions of limited water and limited electrical energy are presented. The critical emergencies can result from extreme drought, electric grid failure, and other severe natural conditions. The basic objective of this study is to apply the two concepts, resilience and quantum resilience, using an optimization-simulation for real-time optimal operation of water distribution system under conditions of limited water and energy availability. The approach adopted in the operation model was to interface an optimization procedure (genetic algorithm) with a simulator (EPANET) in the framework of an optimal control problem. The optimization-simulation model was implemented within the framework of MATLAB. An example system is used to demonstrate the performance of the model and application of the resilience concepts to assess the performance of the system. The results show that for a certain configuration of the system, the resilience values computed by both the methods follow similar trends, while quantum resilience values change with a change in the components of the system.

PhD Candidate
Arizona State University

Puneet received his Bachelor's degree in Civil Engineering from the Maharashtra Institute of Technology, Pune University, India (now known as ‘Savitribai Phule Pune University’) with a gold medal for 'Excellence in Academic Performance' and a Master's (M.S) degree in Civil, Environmental and Sustainable Engineering from Arizona State University in Fall 2015. He is currently pursuing his Ph.D. in Civil, Environmental and Sustainable Engineering at Arizona State University with a specialisation in Hydrosystems Engineeering under the guidance of his advisor Dr. Larry Mays. His research interests include systems approach for water resources, optimization of design for stormwater and water treatment and distribution systems, soil and groundwater remediation, flood control systems, hydraulic structures, and hydrological modelling. Puneet actively participates in various activities of the ASU chapter of Engineers without Borders (EWB) and is currently working on a project for construction of percolation tanks for poor farmers in India. He is also volunteering for a EWB local project aimed at uplifting the standard of living and creating economic opportunities for the Navajo people at Shonto, Arizona.
