CONTAMINATION WARNING IN WATER NETWORKS : GENERAL MIXED-INTEGER LINEAR LOCATION DESIGN

A mixed-integer linear program is proposed to identify optimal sensor locations for early warning against accidental and intentional contaminations in drinking water distribution systems. The general model can be applied to unsteady hydraulic conditions. Furthermore, it may accommodate different design objectives whose problem formulations vary only by the cost function coefficients while decision variables and linear constraints remain identical. Such a feature is very important since several requirements may be factors for practical design of warning systems.
