Abstract:

The availability of water at a point in a distribution network is expressed in terms of the reliabilities of the components which comprise the different paths to the point from the source. As the distribution system ages, component reliabilities decrease and point reliabilities change. The technique of calculating point reliabilities is thus useful in infrastructure maintenance and repair planning. The use of network reliability theory using pathsets and cutsets is applied to determine point reliabilities. An example is presented to demonstrate the validity and usefullness of the model.
