| description abstract | A heuristic approach for reliability-based design of water-distribution systems (WDSs) is presented. The reliability is expressed by reliability factors, estimated through extended-period simulation using node-flow analysis that predicts the availability of water at different nodes during deficient conditions. The approach is iterative, considers pump and pipe failures only, and is based on the trade-off between reliability and cost of the WDSs. An initial WDS is selected and the ratio of marginal increase in reliability to marginal increase in cost (MIRMIC ratio) for each pipe by changing its size to next higher one is evaluated. Pipes with large MIRMIC ratios are selected for change to next higher size and the iterative procedure is continued until a WDS of desired reliability is obtained. The approach can also be applied to reliability-based upgrading of existing WDSs. | |
