Abstract

A delivery server includes: a reception unit configured to receive a set of meter indication data of a gas meter from a mobile terminal; an update unit configured to update a remaining gas amount with use of the set of meter indication date; a prediction unit configured to predict a prospective remaining gas amount in accordance with a prospective daily gas usage predicted based on a daily gas usage consumed in a period from a previous meter reading date to a current meter reading date and a rate of change in a past daily gas usage obtained based on sets of meter indication data of a supply facility in a predetermined past period; and a determination unit configured to determine a date on which the remaining gas amount reaches a predetermined value as a delivery date of a gas cylinder.

Claims

1. A delivery prediction system configured to predict delivery for each of a plurality of gas cylinders installed in a plurality of supply facilities, comprising:

a management unit configured to manage a remaining gas amount in the each of the plurality of gas cylinders in the plurality of supply facilities, and one or more areas of the plurality of supply facilities;

a reception unit configured to receive a set of meter indication data of each of a plurality of gas meters, the plurality of gas meters configured to detect respective gas usages in the plurality of gas cylinders from a communication terminal;

an update unit configured to calculate the gas usage consumed in the each of the plurality of supply facilities in a period from a previous meter reading date to a current meter reading date on a basis of comparison between a set of meter indication data received in the current meter reading date and a set of meter indication data received in the previous meter reading date and configured to cause the management unit to update the remaining gas amount in the each of the plurality of gas cylinders corresponding to the plurality of supply facilities on a basis of the gas usage;

a prediction unit configured to;

calculate a daily gas usage and a first rate of change in a past daily gas usage, the daily gas usage consumed in the period from the previous meter reading date to the current meter reading date and being obtained based on the calculated gas usage, the first rate of change in the past daily gas usage obtained based on sets of meter indication data of the each of the plurality of supply facilities in a predetermined past period;

calculate 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 management unit;

predict a prospective daily gas usage in the each of the plurality of gas cylinders installed in the plurality of supply facilities 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

predict a prospective remaining gas amount by reducing the updated remaining gas amount in accordance with the prospective daily gas usage; and

a determination unit configured to determine a date on which the predicted remaining gas amount reaches a predetermined value as a delivery date of the each of the plurality of gas cylinders in the plurality of supply facilities.

2. A delivery prediction method of causing a computer to predict delivery for each of a plurality of gas cylinders installed in a plurality of supply facilities, the computer including a management unit to manage a remaining gas amount in the each of the plurality of gas cylinders in the plurality of supply facilities, and one or more areas of the plurality of supply facilities, the delivery prediction method comprising:

receiving a set of meter indication data of each of a plurality of gas meters, the plurality of gas meters configured to detect respective gas usages in the plurality of gas cylinders from a communication terminal;

calculating the gas usage consumed in the each of the plurality of supply facilities in a period from a previous meter reading date to a current meter reading date on a basis of comparison between a set of meter indication data received in the current meter reading date and a set of meter indication data received in the previous meter reading date and causing the management unit to update the remaining gas amount in the each of the plurality of gas cylinders corresponding to the plurality of supply facilities on a basis of the gas usage;

calculating a daily gas usage and a first rate of change in a past daily gas usage, the daily gas usage consumed in the period from the previous meter reading date to the current meter reading date and being obtained based on the calculated gas usage, the first rate of change in the past daily gas usage obtained based on sets of meter indication data of the each of the plurality of supply facilities in a predetermined past period;

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 management unit;

predicting a prospective daily gas usage in the each of the plurality of gas cylinders installed in the plurality of supply facilities 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

predict a prospective remaining gas amount by reducing the updated remaining gas amount in accordance with the prospective daily gas usage; and

determining a date on which the predicted remaining gas amount reaches a predetermined value as a delivery date of the each of the plurality of gas cylinders in the plurality of supply facilities.

3. A computer readable storage medium storing a program for causing a computer to execute the delivery prediction method, the delivery prediction method causes the computer to predict delivery for each of a plurality of gas cylinders installed in a plurality of supply facilities, the computer including a management unit to manage a remaining gas amount in the each of the plurality of gas cylinders in the plurality of supply facilities, and one or more areas of the plurality of supply facilities, the delivery prediction method comprising:

receiving a set of meter indication data of each of a plurality of gas meters, the plurality of gas meters configured to detect respective gas usages in the plurality of gas cylinders from a communication terminal;

calculating the gas usage consumed in the each of the plurality of supply facilities in a period from a previous meter reading date to a current meter reading date on a basis of comparison between a set of meter indication data received in the current meter reading date and a set of meter indication data received in the previous meter reading date and causing the management unit to update the remaining gas amount in the each of the plurality of gas cylinders corresponding to the plurality of supply facilities on a basis of the gas usage;

calculating a daily gas usage and a first rate of change in a past daily gas usage, the daily gas usage consumed in the period from the previous meter reading date to the current meter reading date and being obtained based on the calculated gas usage the first rate of change in the past daily gas usage obtained based on sets of meter indication data of the each of the plurality of supply facilities in a predetermined past period;

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 management unit;

predicting a prospective daily gas usage in the each of the plurality of gas cylinders installed in the plurality of supply facilities 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;

predicting a prospective remaining gas amount by reducing the updated remaining gas amount in accordance with the prospective daily gas usage; and

determining a date on which the predicted remaining gas amount reaches a predetermined value as a delivery date of the each of the plurality of gas cylinders in the plurality of supply facilities.
