Description

  The present invention relates to a gas charge system, particularly a LP gas charge system construction method, and a gas charge system construction computer program for causing a computer to execute the construction method.

  LP gas charge systems are diverse, and each gas company charges gas usage fees for each gas consumer based on a standard charge menu and discounted charge menu based on a pay-as-you-go system. A fee structure is set up for this purpose. In the LP gas fee system, various discount unit prices are used depending on the gas consumer's gas usage, the types of gas appliances used, and the gas usage hours. A single company employs dozens of types of fee structures.

  Here, in the Patent Documents 1, 2, and 3, the present inventors have proposed a method for dividing the amount of gas used, a gas fee system based on each divided amount of gas used, and the like. In the gas usage metering method, the gas consumption of each gas consumer is calculated by using a counter. The hot water consumption (large flow) usage, the heating (long time) usage, and the specified time usage It is divided into the amount used for other kitchen areas. In addition, the unit price of the gas usage charge is the standard unit price of the kitchen band usage charge, and the discount unit price is obtained by discounting the other hot water supply unit price, heating zone unit price, and specified time zone unit price by the prescribed discount rate. Is adopted. Adopting such a charge system, for example, is advantageous for sales promotion of gas appliances, such as a gas company increasing the discount rate of hot water supply unit price over other unit prices for expanding sales of gas water heaters. Become.

  As mentioned above, the gas fee system is diverse, and it is difficult for gas companies and gas consumers to understand.

  For example, it is difficult for a gas company to know what fee system is specifically adopted so that a gas consumer can make a profit without feeling expensive. In particular, it is extremely advantageous for a gas company if it is possible to reconstruct a gas fee structure that is more advantageous than the current fee structure.

  On the other hand, it is convenient for gas consumers because if the gas charge system provided by each gas company is disclosed on the Internet or the like, the charges can be compared between the gas companies. However, each gas company has a standard fee system, but various discount rates are set for each gas company and gas consumer. In some cases, a single gas company may have several dozen or more gas charges. In this case, even if the gas charge system is disclosed, it is difficult for the gas consumer to know what charge system is advantageous with the highest discount rate.

Here, if the gas fee system is simplified and disclosed (notified), it will be easy for both gas companies and gas consumers to understand. However, it is expected that excessive price competition will occur between gas companies under such circumstances, which is undesirable. In addition, simply simplifying the gas fee structure will not allow gas companies to adopt a variety of gas fee structures that are appropriate for each gas consumer, and the options for the gas fee structure will be narrowed on the part of the gas consumer. Is not desirable because it becomes rigid and lacks versatility and diversity.

  In view of these points, the problem of the present invention is that a gas company can set or reconstruct an appropriate gas charge system from a huge gas charge system, particularly an LP gas charge system, by a simple operation. And a computer program for constructing a gas charge system for causing a computer to execute the construction method.

  In addition to the above, the object of the present invention is to display a gas fee system in a form that is easy for a gas consumer to understand, so that the gas consumer can easily select or set a gas fee system suitable for him / her. And a computer program for constructing a gas charge system for causing a computer to execute the construction method.

In order to solve the above-mentioned problem, the construction method of the gas charge system of the present invention is:
The first created based on the information on the current rate structure of the gas rate presented to each gas consumer who is a gas company customer and the information on the gas usage amount and the gas usage fee of each gas consumer for a predetermined period Store the database in the computer or in an external storage unit,
When the standard charge calculation request is input, the computer displays an xy coordinate plane in which the gas consumption is taken on the x-axis and the gas charge is taken on the y-axis on the display screen of the display device. Based on the stored information, a point representing each gas consumer is plotted on the xy coordinate plane,
A standard fee line is generated such that the number of points representing each gas consumer plotted on the xy coordinate plane is divided into a vertical direction at a predetermined ratio set in advance, and the generated standard fee line is defined as the xy coordinate. Display on the screen,
When a standard charge setting request is input, the standard charge line is set in the storage unit as a standard charge system for gas usage charges.

  In the method of the present invention, the standard charge line is set so that the past gas charges are positioned at a predetermined rate for gas company customers. For example, in consideration of application of various discount charges, the standard charge line can be drawn so as to have a ratio of 1: 2 up and down. By setting this ratio to an appropriate value, it is possible to apply a discount fee to the standard fee and set an appropriate gas fee corresponding to the gas usage status of each customer. In addition, gas companies can avoid inconveniences such as a significant decrease in revenues compared to the current fee structure. Thus, by setting the ratio appropriately, it is convenient because it is possible to easily perform the initial setting of an appropriate standard fee line based on the results of the current fee system.

  Here, in order to make it possible to easily determine whether or not the initially set standard charge line is appropriate, the computer uses the standard charge system to input the gas company when a revenue calculation request is input. The total revenue of the gas usage fee of each gas consumer may be calculated, and the total revenue may be displayed on the display screen together with the total revenue of the gas usage fee according to the current fee system. By comparing the total revenue, the person in charge of the gas company and the like can confirm whether or not the initially set standard charge line is appropriate in comparison with the past results.

In order to be able to change the standard fee line that has been initially set, when a line change request is input, the computer displays one or more points located on the standard fee line on the display screen. The standard charge line may be changed by moving in the axial direction or the y-axis direction, or both directions.

  Even in this case, the computer calculates and displays the total revenue of the gas usage fee using the changed standard fee line, and allows the person in charge of the gas company or the like to confirm the display contents. When the changed standard charge line is appropriate, a line update request is input. When the line update request is input, the computer may update the standard fee structure set in the storage unit to a standard fee structure defined by the changed standard fee line.

  For example, the standard charge line can be defined by a broken line such that the charge unit price decreases as the gas usage increases. In this case, the standard charge line defines a first line in which the gas usage during the predetermined period defines a first section from 0 to the first point, and a second section from the first point to the second point. A second line and a third line that defines a third segment that is greater than or equal to the second point may be included, and the standard fee line may be changed when the first and second points are moved.

  It is also desirable to be able to perform operations on the screen so that the standard fee line can be easily changed (updated). Therefore, the computer responds to the line update request by the operation button displayed on the display screen or the drag operation of the first and second points by the operator on the display screen. And the second point is moved to change the standard fee line.

  Here, as a discount fee menu for the standard fee structure, a discount fee menu for each application (by gas appliance) can be adopted. For example, the gas charge for the stove uses a standard unit price with a discount rate of zero, the gas charge for the gas water heater, the gas charge for the gas heater, the gas charge used in a specific time zone (specified time zone), etc. A discount rate menu with a discount unit price obtained by discounting the standard unit price at a predetermined discount rate can be adopted.

  In this case, the second database is held in the storage unit. In the second database, among the gas usage amounts, the unit price of the gas usage amount estimated to be the kitchen zone usage amount consumed by the stove is set as the standard unit price, and the hot water consumption zone consumption amount consumed by the water heater The estimated unit price of gas usage is the hot water supply discount unit price, and the unit price of gas usage estimated to be the heating zone usage amount consumed by the heater is the heating discount unit price. Assuming that the unit price of gas usage estimated to be in the specified time zone usage rate is the specified time zone discount unit price, the hot water discount rate menu using the hot water discount unit price, the heating discount rate menu using the heating discount unit rate, the specified time discount unit price Includes a special rate system that employs one, two, or all of the specified time discount rate menus using.

  In this case, when the standard charge calculation request is input, the computer displays at least the lowest charge line representing the gas usage charge at the lowest unit price among the discounted unit prices together with the display screen. It is desirable to display above.

In this way, two charge lines, a standard charge line and a minimum charge line, are displayed on the display screen. Further, if necessary, a charge line with another discount unit price can be displayed. In any case, since the gas charge system is displayed in a form aggregated in two or several charge lines, the gas charge system can be displayed in a state that is easy to understand visually. For example, it can be seen that the discountable range is between the standard charge line and the minimum charge line, and when the discount charge menu is adopted, how much discount is obtained with respect to the standard charge according to the amount of gas used. This is convenient because it can be visually recognized qualitatively. Furthermore, if the line representing the LP gas information center price and the line representing the city gas price (calorie conversion) are displayed in an overlapping manner, the lines compare the suitability of the standard charge system (standard charge line) and the discount charge menu. This is convenient because it can be easily recognized visually.

  Here, when adopting the discount rate menu for each usage as described above, if the usage amount by usage for each gas usage of the gas company customer is not known, what discount unit price should be used? It is unknown whether it is good.

  The inventors of the present invention have proposed a counter having a gas metering function in Patent Documents 1 to 3 cited above. By using such a counter, it is possible to calculate the amount of gas used for each application by dividing the amount of gas used. However, for customers who do not have a minute counter function, only the integrated value of gas usage per predetermined period is known.

  Therefore, in the present invention, the gas usage amount by application is unknown by using the past gas usage status by the customer who has a counter function, that is, the gas usage amount and the usage amount by usage. For those customers, we estimate the gas usage for each application, and based on this, estimate the total revenue of the gas company when adopting the discount menu for each application, so that the appropriateness of the discount menu can be judged. Yes.

  That is, in the present invention, the third database is held in the storage unit. In the third database, each gas consumer is divided into a plurality of usage intervals according to the amount of gas used in a predetermined period based on the gas usage status by a plurality of gas consumers in the past. The gas consumer's gas usage, which is the kitchen zone usage, hot water usage rate, heating zone usage rate, usage rate of the specified time zone usage rate, and each gas consumer in each usage interval The selection ratio of each menu included in the selected special fee system is stored. When the revenue calculation request is input, the computer displays the total revenue based on the standard fee system, and for each gas consumer provided by the gas company based on the information stored in the first database. In addition, based on the usage rate and the selection rate, the total revenue of the gas usage fee obtained by the gas company when the special rate system is adopted is estimated based on the usage rate and the selection rate. It is configured to be displayed.

  In this case, the computer further includes a revenue indicator relating to a difference between a total revenue of the gas usage fee when the current fee system is adopted and a total revenue of the gas usage fee when the standard fee system is adopted, and , And display a profit indicator regarding the difference between the total revenue of the gas usage fee when the current fee system is adopted and the total revenue of the gas usage fee when the special fee system is adopted for the standard fee system. Is desirable.

  As described above, in the method of the present invention, it is possible to estimate the profit when the discount charge menu is adopted, so that the most appropriate discount charge menu for the gas company can be objectively compared with the profit in the case of the current charge system. You can choose.

In this case, the third database further stores usage-specific average data for each predetermined period, and the usage-specific average usage data includes a stove household that is a gas consumer equipped with a stove. Gas consumption average value for each predetermined period of a stove hot water supply household that is a gas consumer equipped with a stove and hot water heater, and a stove hot water supply and heating household that is a gas consumer equipped with a stove, hot water heater and a heater And the ratio of the use of the kitchen band and the hot water supply band in a stove hot water supply household and the ratio of the use of the kitchen band, the use of the hot water supply band and the use of the heating band in a stove hot water heating and heating household When the gas sales target value request is inputted, the computer uses the gas when the gas company adopts the special fee system as the standard fee system. And total revenue of gold, and future of gas increased sales volume, the corresponding relationship between the future of the stove new acquisition the number of hot water supply households or new acquisition the number of the stove hot water heating households,
It is desirable to calculate and display based on the contents of the first, second and third databases.

  In this way, it is extremely convenient because the gas sales target value (the amount of increase in gas sales, the target number of hot water supply households, etc.) can be objectively known.

  On the other hand, if the gas fee structure construction method according to the present invention is adopted, it is possible to present the gas fee structure in an easy-to-understand manner for the customer, and it becomes possible to easily select a discount fee menu suitable for the customer. .

  That is, in the method of the present invention, when a charge menu display request is input, the computer displays a graph, a standard charge list, and a special charge menu list on the display screen. Are the standard charge line, the hot water supply discount charge line representing the gas charge relative to the gas use by the hot water supply discount unit, and the heating discount unit price on the xy plane with the gas use amount on the x axis and the gas charge on the y axis. A heating discount charge line representing the gas charge for the gas usage by the gas and a designated time discount charge line representing the gas charge for the gas usage by the designated time discount unit price are displayed. A standard unit price is displayed, and the hot water supply discount unit price, the heating discount unit price, and the designated time discount unit price are displayed in the special rate menu list. Further, when a special charge menu selection request is input, a gas charge system used for calculating the gas consumption charge of the gas consumer is determined based on the standard charge system and the selected special charge menu, and the storage unit stores It is configured to store and hold.

  Unlike the case where various gas tariffs are displayed by a large number of lines, the upper limit is the standard tariff line representing the standard tariff system without discounts, and the lowest price line (the discount with the largest discount rate) A unit price line) is displayed, and one or two discounted price lines are displayed between the standard price line and the lowest price line. Therefore, the customer can sensuously know how much the gas charge will be when selecting one of the discounted charge lines, and when selecting a suitable one for the customer from many types of charge systems In comparison, the entire gas charge system can be displayed in an easy-to-understand manner. In addition, since the upper limit price is clarified by the standard charge line representing the upper limit, the customer can select an appropriate fee system with peace of mind.

  For gas companies, only the upper limit price is specifically displayed, and various charge systems can be adopted in combination with the discount charge menu, and the specific amount in such a charge system is not displayed. Therefore, it is possible to avoid the occurrence of undesirable situations such as discount competition between gas companies. Therefore, it can be expected that the disclosure and announcement of the LP gas price price that has not been released to the Internet etc. will be promoted.

Next, the present invention is a computer program for causing a computer to execute the above gas fee system construction method,

  Hereinafter, an embodiment of an LP gas fee system construction system to which the present invention is applied will be described with reference to the drawings.

(LP gas charge construction system)
FIG. 1 is a schematic block diagram showing an LP gas fee construction system according to the present embodiment. The LP gas fee construction system 1 (hereinafter simply referred to as “construction system 1”) includes a management computer 2, an input device 3, a display device 4, an external storage device 5, and the like connected thereto. . In addition, LP gas fee system and other LP gas information can be disclosed on a website on the Internet via the web computer 6 or the like.

  The management computer 2 executes the installed LP gas fee building program, thereby creating a first database creation unit 11, a second database creation unit 12, a third database creation unit 13, a standard fee structure database creation unit 14, It functions as a standard fee structure creation unit 15, a profit calculation unit 16, a special fee structure setting unit 17, and the like.

  The management computer 2 receives, through the input device 3, identification information of each gas company, identification information of each gas consumer who is a customer of each gas company, and a current fee structure of the gas price presented to each gas consumer. The information regarding the gas usage amount and the gas usage fee for each gas consumer is input. The first database creation unit 11 of the management computer 2 creates the first database 21 based on the input information and stores it in the storage unit 5.

The storage unit 5 also includes a standard fee structure database 24 that stores the standard fee structure created for each gas company by the standard fee structure creation unit 15. The standard fee system is based on a pay-as-you-go system, for example, and is defined by a line graph in which the charge unit price is gradually reduced as the gas usage increases. As an example in Figure 1, in the standard fee structure, the basic charge 1700 yen / ^{m 3,} measured rate unit price is, the gas consumption is up 0～10M ³ at 520 yen / ^{m 3} is standard rate Yes, up to 20m ³ is a discount unit price of 480 yen / ^{m 3,} 20m ³ or more is a discount unit price was further discount of 430 yen / ^{m 3.}

Further, the storage unit 5 stores a second database 22 created by the second database creation unit 12. The second database 22 includes a master database 22a of a special fee system (discounted price menu) including the following items, and a database 22b of a special fee system created for each gas company. In the following, for the sake of simplicity, it is assumed that the special charge system adopted by each gas company is the same.
Estimated to be the unit consumption of the gas used by the gas water heater among the gas consumption of each gas consumer. Hot water discount rate menu using hot water discount unit price (hot water zone unit price), which is the unit price of gas used, heating discount unit price, which is the unit price of gas usage estimated to be the heating zone consumption consumed by the gas heater Heating discount rate menu using (heating zone unit price) A specified time zone discount unit price (time zone unit price) that represents the unit price of gas usage estimated to be the usage amount of the specified time zone that is consumed during the specified time zone. Use specified time discount rate menu

As shown in FIG. 1, in the special fee system stored in the master database 22a, the counter usage fee for the subtotal for dividing the gas usage by application is 100 yen, the hot water supply zone discount unit price (large flow discount) The unit price is 420 yen / m ^3, which is about 20% discount of the standard unit price, and the heating zone discount unit price (long-time discount unit price) is 370 yen / m ³ , which is about 30% discount. The rate is 420 yen / m ³ , a 20% discount, the same as the band discount unit price.

On the other hand, the third database 23 of the storage unit 5 stores data obtained from gas usage situations (particularly, application-specific distribution information) by a large number of gas consumers in the past. Such data can be obtained from the past gas usage status of the gas consumer in which the counter for the meter is installed. Specifically, the third database 23 includes the following items.
Information that classifies each gas consumer into multiple usage intervals according to the amount of gas usage in a given period based on the gas usage status by multiple gas consumers in the past Gas of each gas consumer in each usage interval The usage rate of the usage rate of the kitchen zone, hot water zone usage, heating zone usage, and specified time zone usage, which is a sub-total value of usage, is included in the special rate system by each gas consumer in each usage interval Ratio of each menu of hot water supply zone discount, heating zone discount, and specified time discount

  For example, as schematically shown in FIG. 2, a point representing a gas consumer is divided into a plurality of usage amount sections a1, a2, a3... According to the gas usage amount. In addition, the average b1 (ratio of the amount of usage of the kitchen zone), b2 (ratio of the amount of usage of the hot water supply zone), b3 (use of the heating zone) Volume ratio), b4 (percentage of specified time zone usage), and average c1 of hot water zone discount, heating discount, and specified time discount selection ratio by gas consumers included in each usage interval (selection of hot water zone discount) Ratio), c2 (selection ratio of heating discount), and c3 (selection ratio of specified time zone discount) are stored and held. Further, for example, as shown in FIG. 3, monthly usage fee average data by use by gas consumers is stored and held.

  When the gas charge system of a certain gas company is the standard charge system and the special charge system shown in FIG. 1, for example, as shown in FIG. 4, a charge menu is displayed on the display screen 4 a of the display device 4. The That is, when a charge menu display request command is input to the management computer 2 via the input device 3 or the like, the graph 41, the standard charge list 42, and the special charge menu list are displayed on the display screen 4a. 43 is displayed.

  In the graph 41, a hot water supply discount representing a gas charge relative to a gas use amount based on a standard charge line 44 and a hot water supply discount unit price (large flow rate unit price) on an xy plane having a gas use amount on the x axis and a gas charge on the y axis. A charge line 45, a heating discount charge line 46 that represents a gas charge with respect to the amount of gas used by a heating discount unit price (long-term unit price), and a specified time that represents a gas charge with respect to the gas use amount by a specified time discount unit price (hour unit price) A discounted charge line 47 is displayed. In this example, the hot water supply discount charge line 45 and the specified time discount charge line 47 are the same line. Although the display is omitted in FIG. 4, the basic charge and standard unit price shown in FIG. 1 are displayed in the standard charge list 42, and the hot water discount shown in FIG. 1 is displayed in the special charge menu list 43. Unit price, heating discount unit price, and specified time discount unit price are displayed.

(New fee structure setting procedure)
Next, using the management computer 2, one gas company registered in the first database 21 replaces the current gas rate system with a new gas rate system (standard rate system and special rate system as shown in FIG. 4). The procedure for changing to) will be described.

  FIG. 5 is a schematic flowchart showing a new fee setting procedure. First, the charge construction program of the management computer 2 is started up and the display screen 4a is changed to a charge setting screen (step ST1 in FIG. 5). In this state, a standard charge calculation request command including identification information for specifying the target gas company is input to the management computer 2 from the display screen 4a or via the input device 3. As a result, the standard fee structure creation unit 15 of the management computer 2 generates a standard fee line and displays it on the display screen 4a (step ST2 in FIG. 5).

  FIG. 6A is an explanatory diagram for illustrating a configuration of a display screen of the generated standard charge line. As shown in FIG. 6A, on the display screen 4 a of the display device 4, an xy plane 61 in which the amount of gas used is taken on the x axis and the gas charge is taken on the y axis is displayed, and the gas registered in the first database 21. A point 62 corresponding to each gas consumer of the gas company is plotted on the xy plane 61 based on the stored information of the company.

  The standard charge system creation unit 15 sets the standard charge line 63 (the published charge) so that the number of points 62 representing each gas consumer plotted on the xy plane 61 is divided above and below the line at a predetermined ratio set in advance. Price line). For example, the standard fee line 63 is generated so that the ratio is 1: 2 above and below the line. The generated standard fee line 63 is displayed as indicated by a bold line. In addition, reference charge line information such as an average charge line 64 (oil information center price line) and a city gas price line (heat amount conversion) 65 provided by the LP Gas Information Center Organization is stored in the storage unit 5 in advance. In addition, these may be displayed together on the display screen 4a.

Further, in this example, together with the standard fee line 63, a gas fee minimum fee line 66 (a fee menu applied lowest price line) is also displayed. The minimum fee line 66 is generated and displayed based on information held in the second database 22. The minimum charge line 66 in this example is a line based on the heating zone discount unit price (370 yen / m ^{3 in} this example) with the lowest discount unit price. Thus, on the display screen 4a, the standard charge line 63 indicating the upper limit price of the gas charge and the minimum charge line 66 indicating the lower limit price are displayed together with the reference price lines (64, 65).

For example, the standard fee line 63 is defined by a broken line. Specifically, the standard fee line 63 includes a first line 63a, a first line 63a that defines a first period from a reference point d0 of 0 to a first point d1 of 10 m ³ for a predetermined period, for example, monthly gas usage. the second line 63b from one point d1 defines a second section to a second point d2 of 20 m ^3, and a third line 63c which defines the third section from the second point d2 to the third point d3 of 30 m ³ , And a fourth line 63d that defines a fourth section beyond that. The gas charge at the reference point d0 corresponds to a basic charge (for example, 1700 yen, see FIG. 1) in the standard charge system.

Here, when the displayed standard fee line 63 is changed (updated) (step ST3 in FIG. 5), a line change request command (line update request command) is sent from the display screen 4a or via the input device 3. Enter. For example, in FIG. 6A, the reference point d0 is moved in the y-axis direction, and the first and second points d1 and d2 are moved in the x-axis direction, the y-axis direction, or both directions (standard line change request The standard charge line 63 can be changed by input). By moving the reference point d0 up and down, the basic charge of the standard charge system can be adjusted. By moving the first point d1 up and down, for example, the standard unit price of the gas rate can be adjusted, and by moving left and right, the application range (gas usage interval) of the standard unit price can be increased or decreased. Similarly, 10-20 by moving the second point d2 up and down.
The unit price in the usage interval up to m3 can be adjusted, and the usage interval to which the unit price is applied can be increased or decreased by moving left and right.

  Of course, it is of course possible to provide a large number of points that can be moved up, down, left and right so that the standard fee line can be changed to various shapes. The example shown in FIG. 6A shows the case of a small number of points for the sake of simplicity.

  Further, for example, as shown by a balloon display in FIG. 6A, the operation of changing the standard fee line 63 by moving each point is the up / down / left / right operation buttons 67 displayed on the display screen 4a or the display screen 4a. Each point displayed above can be performed by an operation in which the operator drags up, down, left, and right with a finger or the like.

  In this example, in the movement operation of each point, the minimum charge line 66 is set as the lower limit, and the price is restricted so that a lower price cannot be set.

  Here, the special fee system registered in the second database 22 can be changed on the display screen 4a. For example, as shown in FIG. 6A, a list 68 of applicable rate plans for setting (updating) a special fee system is displayed in the display area on the right side of the graph on the display screen 4a. The list 68 displays the special fee system stored in the second database 22. In this example, the standard unit price without discount (general) is represented by “100”, the discount rate for the specified time zone (hour) is “20% off”, and the hot water zone discount unit price (large flow rate) is also “20% off”. The heating zone discount unit price (long time) is displayed as “30% off”. The special fee system is set or changed by, for example, a special fee setting request command input via the input device 3.

After the standard charge line 63 is determined through such operations, when the standard charge setting request command is input, the determined standard charge line 63 is stored in the standard charge system database 24 in a form associated with the gas company ( Step ST5 in FIG. 5). For example, the standard charge shown in FIG. 1 (basic charge 1700 yen, unit price up to 10 m ³ is 520 yen, unit price up to 20 m ³ is 480 yen, and unit price up to 20 m ³ is 430 yen) is set. In addition, the special fee system shown in FIG. 1 is set.

  FIG. 6B is an explanatory diagram showing an example of a specific standard charge line display screen. In this figure, the same reference numerals are given to the corresponding parts in FIG. 6A. In the actual display screen, points corresponding to the gas consumers of the gas company plotted on the xy plane 61 based on the storage information of the gas company registered in the first database 21 (points in FIG. 6A). 62) is not displayed. Instead, for example, the plot number ratio table 69 is displayed on the right side of the screen.

  In the example shown in FIG. 6B, a setting table 63A representing the standard fee line 63 is displayed on the lower side of the screen. Here, markers representing the set points of the standard fee line 63, for example, markers 1 to 5, are displayed, the usage amount and the gas fee representing each marker are displayed, and the unit price between the markers is displayed. By specifying and moving each marker, the setting of the usage amount and the amount of money is changed, and the standard fee line 63 is changed.

  Next, after provisional setting of the standard fee line 63, the validity of the set fee system can be confirmed by comparing the total revenue of these with the revenue of the current fee system (step ST4 in FIG. 5). In addition, if it is not appropriate, for example, if the profit significantly deteriorates, an appropriate fee structure can be reconstructed by repeating resetting (updating) the charge structure and displaying the profit.

  FIG. 7 is an explanatory diagram illustrating an example of a profit calculation screen. Referring to this figure, after temporarily setting the standard charge line 63 and the special charge system, when the revenue calculation request command is input to the management computer 2 via the input device 3, the management computer 2 is temporarily set. The total revenue of the gas usage fee of each gas consumer of the target gas company is calculated using the standard fee structure, the display screen 4a is switched to the revenue trial calculation screen 70, and the total revenue is expressed as “sales according to the published tariff ( A2) ”is displayed together with“ Sales based on current fee table (A1) ”, which is the total revenue of the gas usage fee according to the current fee system.

  In addition to displaying the total revenue based on the standard fee structure, the provision of the standard fee structure temporarily set for each gas consumer provided by the gas company based on the information stored in the first database 21 and the third database 23 Estimate the total revenue of the gas usage fee obtained by the gas company when the fee system is adopted, and display it as “sales at the time of introducing a new fee menu (A3)”.

  In addition, a revenue indicator “the difference between the current rate and the published rate (A1) − A difference between the total revenue of the gas usage fee when the current fee system is adopted and the total revenue of the gas usage fee when the standard fee system is adopted (A1) − (A2) ”, and a profit indicator“ the current charge and the difference between the total revenue of the gas usage fee when the current fee system is adopted and the total revenue of the gas usage fee when the special fee system is adopted for the standard fee system ” The difference from the new charge menu (A1)-(A3) "is also displayed.

  Based on these display contents, the person in charge of the gas company can objectively know the validity of the newly set gas charge system. Further, by repeating the resetting of the standard charge line and the resetting of the special charge system based on these display contents, the most preferable gas charge system for the gas company can be reconstructed instead of the current charge system.

  It is also possible to display the gas sales target value on the profit calculation screen. For example, in the third database 23, monthly usage average data according to usage as shown in FIG. 3 is stored. Average usage data by application includes gas stove households that are gas consumers equipped with a stove, gas stove hot water households that are gas consumers equipped with a stove and water heater, and gas that is equipped with a stove, water heater and heater Average monthly gas usage of each stove hot water heating / heating household, the percentage of the kitchen band usage and hot water usage in the stove hot water household, and the kitchen usage / hot water usage in the stove hot water heating / heating household The amount of usage and heating zone usage is included.

  For example, when a gas sales target value request command is input to the management computer 2, “Gas Sales Target Value” is displayed on the profit trial calculation screen 70 of FIG. 7. Here, for example, in a gas company, if the special rate system is adopted as the standard rate system, the total revenue of the gas usage fee, the amount of future gas sales increase, the number of newly acquired stove hot water supply households or the stove hot water heating system The correspondence between the number of newly acquired households is displayed.
