Diagnosis cost output device, diagnosis cost output method, and computer-readable recording medium

A diagnosis cost output method comprising:

• identifying a measuring time required for leakage detection with respect to an installation spacing of sensors, based on information affecting vibration propagation characteristics of a pipe;
• and
• outputting a diagnosis cost with respect to the installation spacing, based on an installation cost of the sensors and a measuring cost generated by leakage detection during the measuring time.

A computer-readable recording medium storing a program that causes a computer to execute:

• processing of identifying a measuring time required for leakage detection with respect to an installation spacing of sensors, based on information affecting vibration propagation characteristics of a pipe;
• and
• processing of outputting a diagnosis cost with respect to the installation spacing, based on an installation cost of the sensors and a measuring cost generated by the leakage detection during the measuring time.
