Management apparatus, management method, and non-transitory computer readable medium

A management method, comprising:

• acquiring, by an acquisition unit, first measurement information from each of a plurality of first sensors configured to be installed in each of a plurality of areas and to measure a gas outflow amount in each of the plurality of areas, and acquiring second measurement information from at least one second sensor configured to be mounted on at least one mobile object and to measure the gas outflow amount in each of the plurality of areas by movement of the at least one mobile object;
• identifying, by an identification unit, an abnormal area, among the plurality of areas, where the gas outflow amount shows an abnormal value, based on each of the first measurement information and the second measurement information;
• authenticating, by an authentication unit, that consistency between the first measurement information and the second measurement information is high when an abnormal area identified by the identification unit based on the first measurement information is an area identical to an abnormal area identified by the identification unit based on the second measurement information;
• a generation unit that generates correction information of a reference value of each of the plurality of first sensors based on the second measurement information, or generates correction information of a reference value of the at least one second sensor based on the first measurement information, or generates correction information of reference values of the plurality of first sensors and the at least one second sensor based on the first measurement information and the second measurement information;
• and
• an output unit that outputs an alert signal to a terminal that manages a first sensor which has provided the first measurement information not showing an abnormal value, when the gas outflow amount based on first measurement information of the first sensor in the abnormal area among the plurality of first sensors does not show an abnormal value, wherein
• the plurality of first sensors send first calibration information including calibration date and time of performing calibration, together with the first measurement information to the management apparatus when calibration has been performed,
• the at least one second sensor sends second calibration information including calibration date and time of performing calibration together with the second measurement information to the management apparatus when calibration has been performed, and
• the generation unit determines whether to generate correction information of the reference value of each of the plurality of first sensors, or to generate correction information of the reference value of the at least one second sensor, based on at least one of the first calibration information or the second calibration information.

A non-transitory computer readable medium for storing a program, when executed by a computer, the program causing the computer to perform:

• acquiring first measurement information from each of a plurality of first sensors configured to be installed in each of a plurality of areas and to measure a gas outflow amount in each of the plurality of areas, and acquiring second measurement information from at least one second sensor configured to be mounted on at least one mobile object and to measure the gas outflow amount in each of the plurality of areas by movement of the at least one mobile object;
• identifying an abnormal area, among the plurality of areas, where the gas outflow amount shows an abnormal value, based on each of the first measurement information and the second measurement information;
• authenticating that consistency between the first measurement information and the second measurement information is high when an abnormal area identified in the identifying based on the first measurement information is an area identical to an abnormal area identified in the identifying based on the second measurement information;
• a generation unit that generates correction information of a reference value of each of the plurality of first sensors based on the second measurement information, or generates correction information of a reference value of the at least one second sensor based on the first measurement information, or generates correction information of reference values of the plurality of first sensors and the at least one second sensor based on the first measurement information and the second measurement information;
• and
