Definitions
- the present invention relates to a gas delivery system, and more particularly, to a gas delivery system for delivering a container filled with liquefied petroleum (LP) gas to a general household, an apartment house, an office, and the like.
- LP liquefied petroleum
- LP gas is divided into imports from gas-producing countries and domestic production by-produced in the production process of petroleum products.
- the import base that stores LP gas transported by tankers from gas producing countries and the oil refining base are called primary bases.
- LP gas is loaded from a primary base into a coastal ship or tank truck and shipped to a secondary base that is a relay base on the coast or inland.
- LP gas that has been transported to the secondary station is transported to LP gas filling stations in various places, and filled in gas containers (gas cylinders) at the filling station.
- the gas container filled at each filling station is delivered by a delivery member to customer homes such as ordinary households, apartment houses, and offices.
- customer homes such as ordinary households, apartment houses, and offices.
- the empty gas container at the customer's house is replaced with the filled gas container, and the empty gas container is collected at the filling station.
- a fixed delivery area is set for the delivery person.
- a delivery slip for 2 to 10 days to be delivered to the customer's home in the delivery area is delivered to the delivery person.
- the delivery slip is created by the delivery manager. First, based on the past gas usage results for each customer, the meter guidelines of the gas meter at the customer's house, delivery results, etc., the remaining amount of LP gas in the gas container is predicted, and the next gas container delivery plan The day is determined. The total of all the customers in the delivery area for which the delivery person is in charge is accumulated, and the delivery amount of the gas container for 2 to 10 days is determined.
- the delivery slip When the delivery person replaces the gas container in accordance with the delivery slip, the delivery date, the meter pointer on the day, the container number, and the security check are entered in the delivery slip.
- the delivery slip is submitted to the delivery manager when the daily delivery work is completed.
- the delivery slip returned to the delivery manager is stored as data for calculating the next scheduled delivery date after being checked by the delivery manager for omissions. Under such a mechanism, many mechanisms for improving the efficiency of delivery of gas containers have been proposed (see Patent Document 1).
- the handy terminal itself is an expensive device, and when it is lost, there is a risk of losing a large amount of customer data.
- the handy terminal had to be brought back to the filling station where the delivery manager is located and connected to the business system to update the data, which lacked real-time information.
- An object of the present invention is to provide a gas delivery system that can significantly reduce distribution costs by reviewing the arrangement of bases such as filling stations and collecting information in real time using a portable terminal.
- an embodiment of the present invention provides a gas delivery system that delivers a gas container to a customer from a hub base that fills the gas container with a gas via a depot that is a reservoir for the gas container.
- the system includes a delivery system connected to a portable terminal of a delivery person delivering the gas container via a network.
- Means for receiving work data including the number of gas containers delivered by the delivery system from a portable terminal of a delivery person in charge of a delivery area provided in the depot; and a gas container delivered by the delivery person on the day Means for aggregating the first delivery data by delivery person including the number of pieces and the work data for all delivery persons in charge of the delivery area of the depot, and calculating the number of stocks remaining in the day of delivery in the depot

- a hub base 102 is installed in the vicinity of the primary base 101.
- the hub base 102 is a base that integrates two functions of a conventional secondary base and a filling station.
- a plurality of depots 103a to 103c are installed under the hub base 102.
- the installation location of the depot 103 corresponds to a conventional filling station, but does not have a facility for performing the filling work, and is merely a delivery container base as a container storage place for gas containers.
- a delivery area is defined in advance in each depot 103 in the same manner as in the past, and a gas container can be delivered to a customer's home in the delivery area by a delivery person in charge of each delivery area.
- the arrangement of the depot and the setting of the delivery area may be performed separately, and a gas container may be loaded from a designated depot for each delivery person and delivered to the customer's house in charge.
- the transport of LP gas between the primary base and the secondary base and the transport of LP gas between the secondary base and the filling station have been performed by tank trucks. Loading from each gas tank installed in the primary base, secondary base and filling station was carried out. Accordingly, since the time required for moving the tank lorries between the bases is long and it takes time for the cargo handling work at each base, the transportation between the bases is limited to one or two round trips per day. In this embodiment, since the hub base 102 is installed in the vicinity of the primary base 101, the moving time of the tank truck 104 between the primary base 101 and the hub base 102 is short, and transportation can be carried out for several rounds a day.

配送システム201は、データベースに格納された顧客ごとの過去のガス使用量の実績等に基づいて、次回のガス容器の配送予定日を決定する。配送員が担当するエリア内において、次回配送予定日が翌日である顧客のガス容器の本数を積算し、配送員ごとに翌日の配送員別配送データ(配送伝票)を生成する。次に、配送システム201は、次回配送予定日が翌日である顧客宅のデータと、各デポ103において配送残となったガス容器の種類・本数のデータとに基づいて、デポ103ごとに翌日のデポ配送データを生成する。さらに、配送員の過去の配送員別配送データ、ランク、休日などの配送実績に基づいて、実際に勤務する配送員に割り当てるので、配送員の効率的な配置も可能となる。
検針とは、検針員によって定期的(毎月)よって行われ、顧客宅のガスメータに示された指針を読み取る作業である。検針員は、携帯端末により、顧客宅のガスメータに添付された2次元コードを読み取り、ガスメータに示された指針を入力して、検針・請求システム202に送信する。検針・請求システム202は、2次元コードに含まれるメータ番号から顧客を特定し、検針年月日とメータ指針とをデータベースに格納する。検針・請求システム202は、受信したメータ指針と、データベースに格納された前回のメータ検針とから、この間(1月ごと)のガス使用量を算出し、請求データを生成する。顧客ごとのガス使用量は、上述した顧客ごとの配送予定日を決定する際に使用される。
保安調査は、定期的に行われる法定の調査、地域ごとに定められた所定の調査、開栓時に行われる調査、設備の故障時に行われる調査などを含み、保安員が、顧客宅のガス容器、ガスメータ等の設備に対して行う調査である。保安システム203は、顧客宅のガス容器、ガスメータ等の設備情報を、データベースに格納している。設備情報には、ガス容器の使用期限等の満期情報、法定の調査項目と過去の調査結果などの情報を含む。
図4に、本発明の一実施形態にかかる配送システムにおける処理内容を示す。配送システム201内のデータベースには、各デポの配送エリアに含まれる顧客宅のデータ(例えば、顧客の個人情報、設置されているガス容器、ガスメータの設備情報、過去のガス使用量の実績、過去の配送実績等)が格納されている。また、過去の配送員別配送データ、配送員のランク、休日などの情報を含む配送員データが、データベースに格納されている。
次に、配送システム201は、デポ配送データを生成する。ステップS412において、デポに設けられた配送エリアを担当する配送員の携帯端末から、当日に配送したガス容器の本数を含む作業データを受信する。
(翌日の搬入本数)=(翌日の配送予定本数)-(当日在庫)
となる。具体的には、トレーラーに積載できるガス容器の本数を考慮して、デポの在庫本数を調整しながら、トレーラー何台を搬入するかを決定する。例えば、説明の便宜のため、ガス容器を1種類、トレーラーの積載本数160本、4台のトレーラーを置くデポの場合を仮定する。翌日の配送予定本数=500本、当日在庫=80本のとき、翌日の搬入本数は、翌日の搬入本数は420本となるが、トレーラーの積載本数を考慮して、トレーラー3台480本を搬入する。すなわち、残ガス容器が搭載されたトレーラー3台と、充填容器が搭載されたトレーラー3台とを、翌日までに交換するように、デポ配送データを生成する。
