WATER LEAKAGE DIAGNOSIS DEVICE, WATER LEAKAGE DIAGNOSIS METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM
A water leakage diagnosis device in an embodiment includes a total water leakage amount acquirer, a node water usage amount acquirer, a node water leakage amount estimator, an estimation parameter setting unit, and a water leakage location estimator. The total water leakage amount acquirer acquires a total water leakage amount in a pipe line network on the basis of an amount of water flowing into a pipe line network and an amount of water used by a customer in the pipe line network. The node water usage amount acquirer acquires a node water usage amount indicating a total amount of an amount of water to be used at each node in the pipe line network. The node water leakage amount estimator estimates the node water leakage amount a plurality of times on the basis of the total water leakage amount, the node water usage amount, and an estimation parameter. The water leakage location estimator estimates a water leakage location in the pipe line network on the basis of a plurality of estimated results of the node water leakage amount. The node water leakage amount estimator estimates the node water leakage amount using different estimation parameters for each of estimations of the node water leakage amount performed a plurality of times.
