Description

The present invention relates to a forecasting technique for forecasting sales of, for example, LPG (Liquefied Petroleum Gas) by using indicator information of a gas meter of a gas supply destination.

LPG is generally delivered in cylinders from gas utilities to gas supply destinations. Gas usage is managed by guideline information obtained from gas meters.
Regarding the prediction of gas usage, it receives guideline information from the gas meter, compares each guideline information to calculate the gas usage, and compares multiple gas usage amounts for a predetermined period before the meter reading date of the guideline information. It is known to calculate the rate of change in the amount of gas used in the past by calculating the rate of change in the amount of gas used in the past, change the amount of gas used according to this rate of change, and predict the amount of gas used after the change as the amount of gas used in the future (Patent Document 1).

JP 2013-254414 A

By the way, the sales of LPG provided by gas companies depend on the amount of gas used by gas supply destinations. This gas usage amount is calculated based on the guideline information of the gas meter. If the guideline information for the current month is acquired, the gas usage amount for the current month is determined by subtracting the guideline information for the previous month from this guideline information. Gas sales information can be calculated by multiplying the amount of gas used by the charge per unit amount used. In other words, unless the guideline information for the current month is determined, the amount of gas used and gas sales cannot be obtained.
In addition to this billing system, the number of gas supply destinations and the amount of gas used by each gas supply destination are fluid. For this reason, gas suppliers are required to predict fluctuations in the number of gas supply destinations and the amount of gas used. In other words, it is essential to predict gas sales based on the amount of gas used by gas supply destinations when purchasing gas. In terms of gas business management, there is a problem that purchasing gas that is not based on gas sales forecasts is untimely and worsens the business situation.
