To provide a gas delivery management system for efficiently carrying out delivery work of gas containers, in accordance with gas usage in each gas consumption area, and a gas delivery frequency distribution based on seasonal variation.SOLUTION: A gas delivery management system 1 calculates a gas usage volume and a gas residual volume in a gas consumption area 4. In a database 34, a monthly average gas usage volume in the gas consumption area 4, and an annual gas delivery frequency distribution are registered. A gas delivery management server 3 extracts a gas consumption area where an annual gas delivery frequency of once or twice is sufficient, as a small volume gas consumption area 4A, on the basis of an average gas usage volume in the gas consumption area 4 and an LP gas cylinder capacity. A delivery period for carrying out the annual gas delivery work to the small volume gas consumption area 4A is set to take place, for example, in the summer season when the delivery frequency is minimal in the gas delivery frequency distribution. Accordingly, leveling of the gas delivery frequency can be attained throughout the year.SELECTED DRAWING: Figure 2
