OPTIMISED ALLOCATION OF HARD QUALITY SENSORS FOR ROBUST MONITORING OF QUALITY IN DRINKING WATER DISTRIBUTION SYSTEMS

A problem of optimised placement of the hard quality sensors in Drinking Water Distribution Systems for robust quality monitoring is formulated. Two numerical algorithms to solve the problem are derived. The optimality is meant as achieving a desired trade off between the sensor capital and maintenance costs and resulting robust estimation accuracy of the monitoring algorithm. The robust estimation algorithm recently developed by the authors is applied as a soft quality in design of the sensor placement algorithms. The methods and algorithms are validated by application to Chojnice DWDS case study. Copyright © 2010 IFAC
