<p>A leak survey scheduling of high cost effectiveness against constraints of limited resources and uncertainty 5 regarding water leaks. Prediction model information to predict the trend of prediction model information in an area is generated on the basis of at least one information item out of leak quantity information, pipeline information, and survey and repair information, and a leak l o survey scheduling to prescribe the sequence of implementing leak surveys in a plurality of areas on the basis of the predicted leak quantity information is drafted. Predicted leak quantity information is generated on the basis of predictions of both the expected value of 15 the leak quantity and the uncertainty of the expected value of the leak quantity, and a leak survey scheduling is drafted by using a calculated leak cost.</p> |
