Gas Demand Prediction System and Gas Demand Prediction Method

A gas demand prediction method of causing a computer to predict gas usages in a plurality of supply facilities, the computer comprising a storage unit configured to store one or more areas in which the plurality of supply facilities are respectively located, the method comprising the steps of:

• receiving respective sets of meter indication data of a plurality of gas meters in the plurality of supply facilities;
• storing the respective sets of meter indication data of the plurality of supply facilities in a storage unit;
• calculating the gas usage consumed in each of the plurality of supply facilities on a basis of comparison between corresponding sets of meter indication data stored in the storage unit;
• calculating a first rate of change in a past gas usage in each of the plurality of supply facilities for the corresponding sets of meter indication data on a basis of comparison between the corresponding sets of meter indication data, and calculating a second rate of change in a past gas usage in the supply facilities located in a same area on a basis of comparison between corresponding sets of meter indication data in the same area stored in the storage unit;
• and
• modifying the calculated gas usage on a basis of the first rate of change in each of the plurality of supply facilities and the second rate of change in the same area as an area in which each of the plurality of supply facilities are located, and predicting the modified gas usage as a prospective gas usage to be consumed in the each of the plurality of supply facilities.

A computer readable storage medium storing a program for causing a computer to execute a gas demand prediction method comprising the steps of:

• receiving respective sets of meter indication data of a plurality of gas meters in a plurality of supply facilities;
• storing the respective sets of meter indication data of the plurality of supply facilities in a storage unit;
• calculating the gas usage consumed in each of the plurality of supply facilities on a basis of comparison between corresponding sets of meter indication data stored in the storage unit;
• calculating a first rate of change in a past gas usage in each of a plurality of gas cylinders the plurality of supply facilities for the corresponding sets of meter indication data on a basis of comparison between the corresponding sets of meter indication data of the each of the plurality of gas cylinders, and calculating a second rate of change in a past gas usage in the supply facilities located in a same area on a basis of comparison between corresponding sets of meter indication data in the same area stored in the storage unit;
• and
• modifying the calculated gas usage in accordance with on a basis of the first rate of change in each of the plurality of supply facilities and the second rate of change in the same area as an area in which each of the plurality of supply facilities are located, and predicting the modified gas usage as a prospective gas usage to be consumed in the each of the plurality of supply facilities.
