Claim 3:
4. A supply quantity adjustment device, comprising:
a processor; and
a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
calculating a total demand quantity used at at least one supply destination, based on plant information acquired from the at least one supply destination;
comparing the total demand quantity and a pre-set flow rate set value and sets a first calculated pressure value;
setting a backup coefficient set value based on a pre-set supply-destination reference gasholder pressure, the first calculated pressure value, a pre-set reference backup pressure set value, and a measured gasholder pressure value, which is a measured pressure value of the supply-destination gasholder;
adjusting a production coefficient by comparing a production pressure set value obtained by adding the pre-set supply-destination reference gasholder pressure and a first pressure output value with the measured gasholder pressure value; and

modifying a variation in the quantity of product gas produced by an at least one air separation apparatus based on the production coefficient.
