Distribution management system and distribution management methods

Abstract

The invention proposes a new technical solution that allows for control over the distribution area and quantity, while also providing gas efficiently. More specifically, the distribution management system manages the distribution of gas cylinders to users who use portable gas fuel contained in cylinders. The distribution management system stores the initial amount of gas in the cylinders delivered to the user group in a database linked to the users and the date of completion of distribution, and records the amount of gas used or the amount of gas remaining after use from the cylinders used within the user group. The refund amount is calculated based on the initial amount of gas and the amount of gas used, or the amount of gas remaining after use.
