漏水調査と修理のモデル

抄録

The theories and policies for the maintenance and renewal of water supply systems are required. The occurrence of water distribution pipe breakage and water leakage is influenced by pipe material, size and age as well as soil characerristics and transportation. The water leakage has to be found as soon as possible from the point of minimizing water loss. However, it costs greater to increase investigations for water leakage. In this study, the model to determine the optimal investigation interval for water leakage of water distribution network was examined. The nonlinear optimization model was theoretically derived. The leakage investigation method with optimal intervals obtained from the presented model was more effective than that with constant interval for all investigation areas.
