Resiliency Assessment Model

The paper introduces a new approach capable to estimate the overall resiliency of water distribution network regarding three aspects namely; water flow, pressure, and water quality. The model begins by evaluating three kinds of resiliencies that is; demand resiliency, pressure resiliency, and water quality resiliency. Then, a model is developed that aggregates all the indicators into one index that depicts the overall resiliency for each single node. The aggregation is performed through the integration of the analytical hierarchy process with fuzzy set approach. The methodology has been demonstrated using a real water distribution system under normal operating conditions
