The user terminal 1 is an information processing device operated by the user U, and is composed of, for example, a smartphone or the like. By executing the application program on the user terminal 1, for example, the following processing is performed. That is, in the user terminal 1, the information (hereinafter referred to as "inventory information") regarding the inventory of ingredients (hereinafter referred to as "inventory ingredients") in the refrigerator or the like of the user U, one or more types of elements, and within the special sale period. A multi-day menu is presented based on information on special sale ingredients (hereinafter referred to as "sale information") that can be purchased at a lower price than purchasing outside the special sale period.
The server 2 is a server that manages the information processing system shown in FIG. 1, and collects special sale information required for processing executed by the user terminal 1, for example. The special sale information collection process may be executed on the user terminal 1. In addition, the server 2 manages the results of menus recommended by the user terminal 1 (hereinafter referred to as "recommended menus") as log data. The result of the recommendation menu may be stored in the user terminal 1 itself. By managing the results by the server 2, it is possible to deal with a failure or loss of the user terminal 1. In addition, by accumulating the results of the recommendation menu, the accumulated results can be utilized as big data. Real menus, which are menus actually created by the user, may be accumulated together with the recommended menus or in place of the recommended menus.

FIG. 2 is a block diagram showing a hardware configuration of the user terminal 1 in the information processing system of FIG.

The user terminal 1 is an information processing device operated by the user U, and is a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, and an admission recommendation. It includes an interface 15, a display unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20.

The CPU 11 executes various processes according to the program recorded in the ROM 12 or the program loaded from the storage unit 18 into the RAM 13.
Data and the like necessary for the CPU 11 to execute various processes are also appropriately stored in the RAM 13.

The CPU 11, ROM 12 and RAM 13 are connected to each other via the bus 14. An admission recommendation interface 15 is also connected to the bus 14. A display unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20 are connected to the input recommendation interface 15.

The display unit 16 is composed of a display such as a liquid crystal display and displays various images.
The input unit 17 is composed of, for example, a capacitance type or resistance film type (pressure sensitive type) position input sensor laminated on the display surface of the display unit 16 and detects the coordinates of the position where the touch operation is performed.
Here, the touch operation means an operation of contacting or approaching an object with respect to the input unit 17. An object that comes into contact with or is in close proximity to the input unit 17 is, for example, a user U's finger or a touch pen.
As described above, in the present embodiment, the touch panel is composed of the display unit 16 and the input unit 17.

The storage unit 18 is composed of a DRAM (Dynamic Random Access Memory) or the like, and stores various data.
The communication unit 19 communicates with another device (for example, the server 2 in FIG. 1) via the network N including the Internet.

A removable media 30 made of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately mounted on the drive 20. The program read from the removable media 30 by the drive 20 is installed in the storage unit 18 as needed.
Further, the removable media 30 can also store various data stored in the storage unit 18 in the same manner as the storage unit 18.

Although not shown, the server 2 in FIG. 1 also has basically the same configuration as the hardware configuration shown in FIG. 2, excluding the display unit 16 and the input unit 17 constituting the touch panel. ing.

Next, the functional configuration of the user terminal 1 having such a hardware configuration will be described with reference to FIG.
FIG. 3 is a functional block diagram showing an example of the functional configuration for realizing the menu recommendation process and the achievement degree calculation process among the functional configurations of the user terminal 1 of FIG. 2 in the information processing system of FIG.

The "menu recommendation process" is a series of processes executed by the user terminal 1 until the menu (recipe) for a plurality of days is recommended based on the inventory information of the user U and one or more kinds of elements. Say.
“Menu” refers to a type of dish that is composed of one or more ingredients and can be arranged on the table of user U.
"One or more types of elements" means any elements that should be considered when recommending a menu, excluding the elements indicated by inventory information.
The element may be a predetermined fixed one or may be arbitrarily selected by the user U. It suffices if the number of elements is 1 or more. For example, when the element "nutrition balance" is selected, among the menus that can be created using at least one kind of ingredients specified by the inventory information, the menu that takes nutritional balance into consideration is recommended. Determined as a target. Other examples of elements include "use-up", in which menus for preferentially using items with close expiration dates in order to use up inventories as much as possible are decided as recommendations, and "savings" in order to reduce food expenses as much as possible. There are "preferences" that match the user's tastes as much as possible, and "bargains" that use ingredients that are on sale, but they are not limited to these.

The "achievement level calculation process" is the achievement of each element after acquiring information on the menu actually created by the user U (hereinafter referred to as "real menu") as a history among the processes executed by the user terminal 1. A series of processes up to the calculation of the degree.
The "achievement level" may be a value calculated for each element within a predetermined period based on the comparison result between the recommended menu and the real menu based on a comparison standard predetermined for each element. .. For example, if menus for a predetermined period (for example, one month) are recommended based on the element of "nutrition balance", each of the recommended menus for the recommended one month is created during the one month. Each of the real menus made is compared. Then, the degree of achievement is calculated based on the comparison result. That is, based on the nutritional balance indicated by the recommended menu, the value such as the ratio indicating how much the nutritional balance indicated by the real menu is achieved with respect to the standard is the "achievement degree".
"Nutrition balance" refers to the relationship between the relative amounts of each nutrient, and may be calculated based on the number and amount of ingested ingredients and nutrients. It may be classified into such as, and calculated based on the number and amount of each category of ingested food. The nutritional balance may be calculated by adding the calorie intake.
As another example of the "achievement level", a certain numerical value to be achieved may be set for each predetermined period and compared with the numerical value calculated from the real menu for the predetermined period. For example, in the case of "nutrient balance", the amount (numerical value) to be ingested in a predetermined period (for example, one day) is set for each nutrient, and the result of comparison with the numerical value calculated from the real menu is arranged in parallel. The set may be referred to as "achievement level", and one value obtained by adding or averaging the results of comparison for each nutrient may be referred to as "achievement level".

As shown in FIG. 3, in the CPU 11 (FIG. 2) of the user terminal 1, when the menu recommendation process is executed, the inventory information acquisition unit 101, the element reception unit 102, the weighting unit 103, and the special sale The information acquisition unit 104, the menu recommendation unit 105, the designated food receiving unit 106, and the designated menu reception unit 107 function.
Further, when the achievement degree calculation process is executed, the real menu acquisition unit 108, the comparison unit 109, and the achievement degree calculation unit 110 function.
In one area of the storage unit 18 (FIG. 2), an inventory DB 401, a food material DB 402, a special sale DB 403, a menu DB 404, a real menu DB 405, and an element DB 406 are provided. The storage unit 18 may be arranged on the server 2 instead of the user terminal 1.

The inventory information acquisition unit 101 acquires inventory information. The inventory information acquired by the inventory information acquisition unit 101 is stored and managed in the inventory DB 401. As a result, the user terminal 1 can accurately manage the in-stock ingredients without omission.
Specifically, for example, when the user U procures ingredients by purchasing, transferring, cultivating, or the like and inputs information on these ingredients by the input unit 17, the inventory information acquisition unit 101 acquires the information as inventory information. .. More specifically, for example, the inventory information acquisition unit 101 can acquire all information related to the ingredients such as the type, price, quantity, contained nutrients, taste / expiration date, and presence / absence of allergic components of the ingredients as inventory information.
Regarding a specific method for the user terminal 1 to acquire inventory information, for convenience of explanation, a method in which the user U inputs by the input unit 18 is adopted, but the method is not particularly limited thereto. For example, although not shown, a method of taking a picture of the inside of a refrigerator or the like, the user terminal 1 recognizing the stocked foods contained in the picture by image processing or the like, and acquiring the stock information based on the recognition result. You may adopt it. Further, for example, the user terminal 1 uses a built-in camera (not shown) or the like to image a predetermined identifier printed on the food material package or the like, recognizes the stock food material based on the imaging result, and recognizes the stock food material. A method such as acquiring inventory information based on the result may be adopted.

The element receiving unit 102 receives one or more types of elements selected by operating the input unit 17 of the user U. As a result, the user terminal 1 can grasp for what purpose the user U wants to create the menu. The elements received by the element receiving unit 102 are stored and managed in the element DB 406 in advance.
Specifically, for example, when the element "use up" is selected by the user U, the element receiving unit 102 accepts these elements. As an example of an algorithm for recommending menus in this case, for example,
(1) The menu information stored in the menu DB is read out, and the type and amount of each ingredient used for the read menu (referred to as "M") are extracted.
(2) Of the types and quantities of ingredients extracted in (1), the types and quantities of ingredients that match the inventory information (referred to as "F (i) (i = 1, ..., N)") and quantity ("Q (" i) ”) is specified. In addition, the number of days until the expiration date of the foodstuff (referred to as "D (i)") is acquired.
(3) Calculate the degree of use-up of ingredients E (M) = Σ _i F (i) × Q (i) / D (i) (i = 1, ..., N) of the menu including the expiration date.
(4) The processing of (1) to (3) is repeated _{to specify the menu M max} (j) (j = 1) at which E (M) is maximized.
(5) Repeat the processes (1) to (4) until the number of menus (N) prepared for one meal is reached, and E (excluding _{the menu M max (j) specified in the previous process) The menu M max} (j) (j = 2,3, ... N) that maximizes M) is specified.
However, it is not limited to this. For example, as a condition for repeating the processing of (1) to (4) in (5), the gram obtained by replacing the number of menus prepared for one meal or with the menu prepared for one meal. The number and calorie intake may be adopted. Also, for example, when reading the menu in (1), specify the type and amount of ingredients whose expiration date is less than one day from the inventory information, read the menu including the ingredients, and use up the ingredients 1 or more. After identifying and using up the menu, the above-mentioned processes (1) to (5) may be performed. Further, for example, for foodstuffs whose expiration date is less than one day, the value of E (M) may be made extremely large by setting D (i) to a value close to 0 in the process of (3).

Further, as another example of how the elements are selected, for example, when the element "bargain" and the element "use up" are selected by the user U, the element reception unit 102 accepts these elements. As an example of Argolim for recommending menus in this case, for example, instead of (1) above,
(1') The menu information stored in the menu DB is read out, and the type and amount of each foodstuff used for the menu (“M”) including the special sale information in the foodstuff is extracted.
After that, the above-mentioned processes (2) to (5) may be performed, but the present invention is not limited to this.

Further, as another example of how the elements are selected, for example, when the element "nutrition balance" and the element "use up" are selected by the user U, the element reception unit 102 accepts these elements. In this case, the purpose of the user U is to create an economical menu while giving consideration to health. As an example of the menu for recommending menus in this case, for example, the above-mentioned processing (1) is performed, and (2) to (3) are replaced.
(2'') Of the types and quantities of ingredients extracted in (1), the types and quantities of ingredients that match the inventory information (referred to as "F (i) (i = 1, ..., N)") and quantity ("" Q (i) ”) is specified. In addition, the expiration date of the foodstuff (referred to as "D (i)") and the type and amount of nutrients contained in the foodstuff (referred to as "N (k)) (k = 1, ..., M)") And the quantity (let's say "R (k)").
(3'') The degree of use of the ingredients of the menu considering the expiration date and the utility of the ingredients considering the nutritional balance E (M) = a × Σ _i F (i) × Q (i) / D ( i) Calculate (i = 1, ..., n) + b x Σ _k N (k) x R (k) (k = 1, ..., m). Here, a and b are coefficients determined based on the weighting performed by the weighting unit 103, which will be described later.
The above-mentioned processes (4) and (5) may be performed after the above-mentioned processing is performed, but the present invention is not limited to this. For example, a and b in (3'') may be predetermined values.
The method in which the user U selects one or more types of elements is not particularly limited. For example, the user U may be able to select one or more types of elements from a plurality of types of elements displayed on the display unit 16 of the user terminal 1.

When there are a plurality of elements received by the element receiving unit 102, the weighting unit 103 weights each of the plurality of types of elements based on a predetermined determination criterion.
As a result, when the user U wants to create a menu based on a plurality of purposes, the user U can give a priority to each of the plurality of purposes.
Specifically, when there are a plurality of types of elements selected by the user U, the weighting unit 103 weights each of these elements. For example, when two types of elements, "nutrition balance" and "use-up", are selected by user U, the element that user U wants to prioritize among these two types of elements is Weighting is done so that the menu is recommended with content that takes precedence over the other element.
When weighting each of a plurality of types of elements, a priority is given to each element, but the method of giving this priority is not particularly limited. For example, the user U may perform an operation of assigning a priority to the input unit 17 for each of the plurality of types of elements displayed on the display unit 16 of the user terminal 1. Specifically, for example, the user U can arbitrarily set the content of the radar chart on which the values obtained by normalizing the priority of each of the plurality of types of elements as shown in FIG. 4 to be described later are plotted. Is also good.

Further, instead of the element receiving unit 102, or together with the element receiving unit 102, the element receiving unit 103 may receive one or more types of elements selected by the operation of the user U on the input unit 17. For example, in the radar chart shown in FIG. 4, the priority of the element not to be selected may be set to "0", and the element to be selected may be set to a value of "1" or more.

Further, the element receiving unit 102 and the weighting unit 103 are not indispensable configurations. In the absence of these, the menu is determined as a recommendation target based on a predetermined algorithm. For example, as in the case where the element "use up" is selected by the user U, a menu for preferentially using items with a near expiration date in order to use up the inventory items as much as possible is determined as a recommendation target.

Further, as another example of the predetermined algorithm, the special sale information acquired by the menu recommendation unit 105, which will be described later, is the same as when the element "bargain" and the element "use up" are selected by the user U. Menus for preferentially using items with close expiration dates are determined as recommendations in order to use up the items in stock as much as possible.

In addition, one or more specific types of elements are set as fixed elements, other one or more types of elements are set as variable elements, and only one or more types of elements that are variable elements are weighted by giving priority. It is also possible to adopt a method such as performing. For example, of the first element of "nutrition balance", the second element of "use-up", and the third element of "preference", the second element is a fixed element, and the first and third elements are variable elements. Can be.
In this case, priority is set for each of the first element and the third element, which are variable elements, and weighting is performed based on the set contents. That is, the menu of economical contents based on the second element as a basic fixed element is recommended by the user terminal 1, but the weighting of the first element and the third element as variable elements is changed. be able to.
As a result, the user U can add not only fixed elements but also elements that he / she wants to consider in creating the menu as variable elements, and can change the weighting according to the importance that he / she wants to consider. For example, in the above example, the user terminal 1 recommends a menu that has a good nutritional balance and is as preferable as possible, while being an economical menu that prioritizes the use of stocked ingredients. Become. Further, the user U only needs to perform a simple operation on the touch panel (input unit 17) when receiving a menu recommendation in consideration of such a variable element.

As a result, the user terminal 1 can recommend the menu based on one or more kinds of elements selected by the user U.
Further, when the user U selects an element related to the inventory information such as "use up", the menu recommendation unit 105 uses the inventory information acquired by the inventory information acquisition unit 101 and the weighting unit 103. We recommend multi-day menus that can be created based on each of the multiple weighted elements.
As a result, the user terminal 1 can recommend menus for a plurality of days without wasting ingredients.

The special sale information acquisition unit 104 acquires special sale information as information on special sale ingredients that can be purchased at a lower price than purchasing outside the special sale period if the purchase is made within the special sale period. The special sale information also includes information on coupons to which discount benefits are given. The special sale information acquired by the special sale information acquisition unit 104 is stored and managed in the special sale DB 403.
As a result, the menu recommended by the user terminal 1 can include specially-sold ingredients. Therefore, it is possible for the user U to enjoy the economic merit.
Specifically, the special sale information acquisition unit 104 acquires the special sale information acquired and managed by the server 2 at a predetermined timing. For example, when the special sale information described in the advertisement of the supermarket where the user U can visit is managed by the server 2, the user terminal 1 may acquire the special sale information every day. The "advertisement" referred to here includes a leaflet inserted in a newspaper, a description on a homepage, and the like.
In addition, the specific method for acquiring the special sale information is not particularly limited. For example, the user U may be able to download the special sale information posted on the website on the Internet by operating the user terminal 1. Further, the user terminal 1 may adopt a method of capturing an image of a newspaper insert leaflet or the like with a built-in camera (not shown) and automatically recognizing special sale information based on the imaged result. Alternatively, the special sale information may be temporarily stored in the server 2 by the API connection from the Web service on the Internet, and the special sale information acquisition unit 104 may acquire the information. The special sale information acquisition unit 104 may directly acquire the special sale information from the Web service on the Internet by API connection. The special sale information acquisition unit 104 may acquire the special sale information from the application that acquires and manages the special sale information running on the user terminal 1.

In addition, the menu recommendation unit 105 can recommend a menu that includes one or more ingredients that are not included in the in-stock ingredients (hereinafter referred to as “out-of-stock ingredients”).
Specifically, for example, when the in-stock food does not contain radish, the radish is an out-of-stock food. At this time, the menu recommendation unit 105 can also recommend a menu for a plurality of days that can be created in combination with the in-stock ingredients by adding radish as an out-of-stock ingredient. It is also possible to propose that radish should be procured as an out-of-stock ingredient if the radish is not in stock even though the menu that should be recommended based on the set factors requires radish as an ingredient. ..

In addition, the menu recommendation unit 105 creates a recommended menu that includes the special sale ingredients related to the special sale information as materials based on the special sale information.
Specifically, for example, the special sale information acquired by the special sale information acquisition unit 104 includes information that the price of the radish sold in the supermarket of the user U is 50 yen per bottle for today only. Imagine a case. At this time, the menu recommendation unit 105 displays the special sale information on the user terminal 1 and displays the recommended menu containing radish as a material.
In this case, the menu may be recommended based on the elements accepted by the element reception unit 102, except that it is essential to include the radish in the material, and it is only essential to include the radish in the material. Therefore, it may be performed without being based on the element received by the element receiving unit 102.
In addition, when the designated menu reception unit 107, which will be described later, receives the designation of the displayed recommended menu from the user U, the user U receives the menu recommended based on the inventory information on that day, or on that day and after that date. You may change to the recommended menu specified by.

The designated foodstuff reception unit 106 receives the foodstuff designated by the user U (hereinafter referred to as “designated foodstuff”). Then, the menu recommendation unit 105 displays the recommended menu containing the designated ingredient in the material on the user terminal 1.
In this case as well, the menu may be recommended based on the elements received by the element reception unit 102, except that it is essential to include the designated ingredients in the ingredients, and it is essential to include the designated ingredients in the ingredients. However, it may be performed without being based on the element received by the element receiving unit 102. In addition, when the designated menu reception unit 107, which will be described later, receives the designation of the displayed recommended menu from the user U, the user U receives the menu recommended based on the inventory information on that day, or on that day and after that date. You may change to the recommended menu specified by.
As a result, when the user U wants to create a menu using desired ingredients, he / she can specify the ingredients by operating the user terminal 1.
At this time, if the foodstuff designated by the user U is an in-stock foodstuff, the menu recommendation unit 105 recommends a menu that can be created using the in-stock foodstuff.

On the other hand, when the foodstuff specified by the user U is an out-of-stock foodstuff, the menu recommendation unit 105 needs to procure the out-of-stock foodstuff in order to create a menu to be recommended. To present.
Specifically, for example, when the user U wants to eat beef tonight, by operating the user terminal 1, "beef" is selected as a desired ingredient from one or more kinds of ingredients stored in the ingredient DB 402. ".
At this time, if the beef is an in-stock ingredient, the menu recommendation unit 105 displays the recommended menu that can be created using the beef on the user terminal 1.
On the other hand, when the beef is an out-of-stock ingredient, the designated ingredient reception unit 106 notifies the menu recommendation unit 105 that the beef is an out-of-stock ingredient, and the menu recommendation unit 105 uses the beef. In addition to the recommended menu that can be created, the user terminal 1 displays that it is necessary to procure beef in order to create the menu to be recommended.

When a plurality of menus including one or more kinds of in-stock ingredients are recommended by the menu recommendation unit 105, the designated menu reception unit 107 is designated by the user U from among the plurality of menus (hereinafter, “designated menu”). ") Is accepted. Further, the menu recommendation unit 105 notifies the designated food reception unit 106 of the designated menu to be recommended, and the designated food reception unit 106 specifies the necessary food from the menu DB and specifies the food material in the designated food reception unit 106. Notify to. The designated food receiving unit 106 notifies the menu recommendation unit 105 whether the food is in-stock food or out-of-stock food. When the foodstuff is out of stock, the menu recommendation unit 105 displays on the user terminal 1 that it is necessary to procure the foodstuff out of stock.
As a result, when the user U wants to create a desired menu from a plurality of types of menus recommended by the user terminal 1, the user U can specify the menu by operating the user terminal 1. ..
The designated menu reception unit 107 may receive the designated menu from the menu recommendation unit 105 based on the user's operation, for example, the user U directly inputs the menu name from the user terminal 1.
Specifically, for example, when the user U wants to eat "sukiyaki" tonight, the user U is stored in the menu DB 404 by operating the user terminal 1 such as inputting "sukiyaki" as the menu name. From one or more types of menus, specify "sukiyaki" as the desired menu. Then, the designated menu reception unit 107 accepts the "sukiyaki" designated by the user U as the designated menu.
At this time, "beef" is specified as an ingredient required to create "sukiyaki" from the menu DB 404, and if is a non-stock ingredient, the menu recommendation unit 105 creates "sukiyaki". Notify the menu recommendation unit 105 that it is necessary to procure beef in order to do so, and display that fact on the user terminal 1.

The real menu acquisition unit 108 acquires the menu actually created by the user U (that is, the real menu).
Specifically, the user U inputs the contents of the menu actually created by the user U by operating the input unit 17 of the user terminal 1. The content input to the input unit 17 is acquired by the real menu acquisition unit 108 as a real menu.
As a result, the user terminal 1 can acquire information for comparing the multi-day recommended menu recommended by the menu recommendation unit 105 with the real menu created during the same period.
The method in which the user U inputs the real menu by operating the input unit 17 of the user terminal 1 is not particularly limited. For example, the user U may manually input the contents of the real menu. In addition, the user terminal 1 employs a method of capturing daily real menus using a built-in camera or the like (not shown) and automatically recognizing the specific contents of the real menus based on the captured images. Is also good. Further, the menu recommendation unit 105 may notify the real menu acquisition unit 108 as a real menu of the menu selected by the user U from the recommended menus displayed by the menu recommendation unit 105.

The comparison unit 109 compares the recommended menu with the real menu based on a predetermined comparison standard determined for each of one or more types of elements.
Specifically, for example, the comparison standard in the element of "nutrition balance" can be the type and amount of nutrients contained in one or more foodstuffs constituting the menu. In this case, it may be possible to compare the types and amounts of nutrients contained in each of one or more foodstuffs constituting the recommended menu and the real menu.
Further, for example, the comparison standard in the element of "use-up" can be the type and amount of foodstuffs that could not be used up within a predetermined period. In this case, it may be possible to compare the types and amounts of ingredients that could not be used up within a predetermined period for each of one or more ingredients constituting each of the recommended menu and the real menu.
The comparison unit 109 may compare a certain numerical value to be achieved for each predetermined period with a numerical value calculated from the real menu for the predetermined period.

The achievement degree calculation unit 110 calculates the achievement degree for each of one or more types of elements based on the comparison result by the comparison unit 109.
As a specific example, the type and amount of nutrients contained in the ingredients of the real menu are the types and / or amounts of nutrients contained in the ingredients of the recommended menu, or a certain type and amount to be achieved at regular intervals. / Or assume that the amount is significantly less than the amount. In this case, the achievement level of the real menu calculated based on the comparison result of the element "nutrition balance" is, for example, the achievement level for the recommended menu "100" by performing the normalization process for each of one or more types of elements. It is possible to set a value such as "40". Alternatively, the degree of achievement may be set as (lipid, vitamin / mineral, sugar) = (80, 40, 100) as a set of values in which the comparison results for each nutrient are arranged in parallel.
In this way, by calculating the degree of achievement of the real menu with respect to the recommended menu based on the comparison standard determined in advance for each element, the user U can easily confirm his / her past achievements.
As a result, the user U can reflect on the points to be reflected and maintain the good points in the future, and utilize the achievement level of each element in the decision of the future menu.

In addition, the achievement level calculated numerically for each element can be displayed in a graph as shown in FIG. 10 described later. As a result, the user U can grasp the achievement level of each of a plurality of types of elements at a glance, and can easily recognize what element has a problem.
The degree of achievement in this embodiment employs a method of displaying numerical values and graphs, but is not limited to this method. For example, it may be a picture or a character whose achievement level can be recognized by an image instead of a numerical value, or the achievement level may be indicated by a difference in color.

Next, with reference to FIG. 4, a specific method for causing the user U to weight each of the plurality of types of elements will be described.
FIG. 4 is a radar chart showing an example of a specific method for causing the user U to specify the weighting for each of the plurality of types of elements.

The elements P1 to P5 shown in FIG. 4 are all elements required for the user terminal 1 to recommend the menu to the user U. Specifically, for example, the element P1 of "nutrition balance", the element P2 of "use up", the element P3 of "preference", the element P4 of "bargain", and the element P5 of "budget" can be used.
The values plotted on the radar chart of FIG. 4 are values obtained by normalizing the priorities (that is, the degree of weighting) of a plurality of types of elements. Among the values plotted on the radar chart of FIG. 4, the priority of "1" is the lowest and the priority of "5" is the highest. Further, the values indicating the priorities of the elements P1 to P5 are connected by a solid line. The default value of the value indicating the degree of weighting of each element is "3" shown by the broken line.
By arranging numerical values indicating the degree of weighting in a radial pattern for each of the plurality of types of elements in this way, the degree of weighting of each of the plurality of types of elements can be compared at a glance. The method of arranging the numerical values indicating the degree of weighting in a radial pattern is not particularly limited, but a radar chart as shown in FIG. 4 is displayed on the display unit 16 of the user terminal 1, and the user U displays the numerical values on the radar chart. It may be set arbitrarily. In this case, the weighting unit 103 weights each of the plurality of types of elements based on the numerical value (numerical value indicating the degree of weighting) input by the user U.

In the example of FIG. 4, the value indicating the weighting degree of the element P1 is "3", the value indicating the weighting degree of the element P2 is "4", and the value indicating the weighting degree of the element P3 is "5". , The value indicating the weighting degree of the element P4 is "2", and the value indicating the weighting degree of the element P5 is "1". The user terminal 1 recommends the menu to the user U based on the degree of this weighting.
As an example of how to set the radar chart, for example, the user U may be able to change the shape of the radar chart so that the sum of the values of each element is equal. Before and after the change, the sum of the values of each element is equal, and based on the positional relationship between the element specified by the user U and the other elements on the radar chart, the value of the element specified by the user U is changed according to the change. You may change the values of other elements. For example, if the user U receives an instruction to increase the value of the first element (P1) by 2 units while the values of all the elements are displayed as "3" on the radar chart, the value of the first element (P1) is automatically changed to the first element. The shape of the radar chart may be modified by reducing the adjacent second element (P2) and fifth element (P5) by one unit and not changing the values of the third element and the fourth element. Further, when the user U receives an instruction to increase the value of the first element (P1) by 6, the second element (P2) and the fifth element (P5) adjacent to the first element are automatically decreased by two units, and the first element (P1) is increased by two units. The shape of the radar chart may be modified so that the values of the 3rd element and the 4th element are reduced by 1 unit. Then, when the user U receives an instruction to increase the value of the first element (P1) to the sum of the values of each element, the value of the second element to the fifth element may be set to 0. Alternatively, when the binch out operation is accepted, the values of all the elements may be increased. By changing the radar chart in this way, it is possible to avoid the hassle of having to specify all the elements one by one, and it is possible to smoothly transform the radar chart according to the user's operation. Become.

Next, with reference to FIG. 5, the menu recommendation process executed by the user terminal 1 having the functional configuration of FIG. 3 will be described.
FIG. 5 is a flowchart illustrating a flow of a menu recommendation process for a plurality of days executed by the user terminal 1 of FIG.

As shown in FIG. 5, the user terminal 1 executes the following series of processes.
In step S1, the inventory information acquisition unit 101 acquires information on inventory ingredients as inventory information. The inventory information acquired by the inventory information acquisition unit 101 is stored and managed in the inventory DB 401.
In step S2, the element receiving unit 102 receives one or more types of elements selected by the user U.

In step S3, the weighting unit 103 determines whether or not there are a plurality of types of elements received by the element receiving unit 102.
If there are a plurality of types of elements received by the element receiving unit 102, it is determined to be YES in step S3, and the process proceeds to step S4. On the other hand, if there is only one element received by the element receiving unit 102, it is determined to be NO in step S3, and the process skips step S4 and proceeds to step S5.

In step S4, the weighting unit 103 weights each of the plurality of types of elements based on a predetermined determination criterion.
In step S5, the special sale information acquisition unit 104 acquires the special sale information.
In step S6, the menu recommendation unit 105 includes inventory information stored in the inventory DB 401, special sale information stored in the special sale DB 403, ingredients required for the menu stored in the menu DB 404, and an element reception unit. Based on one or more elements accepted by 102, we recommend a multi-day menu that can be created. When the element received by the element receiving unit 102 does not have an element related to the inventory information such as "use up", the menu recommendation unit 105 stores the special sale information stored in the special sale DB 403 and the menu DB 404. A multi-day menu that can be prepared may be recommended based on the ingredients required for the menu and one or more kinds of elements received by the element reception unit 102. This completes the menu recommendation process.
By executing the series of processes as described above by the user terminal 1, menus for a plurality of days are recommended based on one or more kinds of elements.

Next, with reference to FIG. 6, the logic of the menu recommendation process for a plurality of days executed by the user terminal 1 will be described.
FIG. 6 is an image diagram showing the logic of the menu recommendation process executed by the user terminal 1 of FIG. 3 when an element related to inventory information exists in the element received by the element receiving unit 102.

As shown in FIG. 6, the inventory amount of the food material V is represented by a polygon Y in which the horizontal axis is the expiration date as a temporal element and the vertical axis is the procurement amount (inventory amount) of the food material V. Unless additional procurement is performed, the inventory amount of the food material V will gradually decrease due to daily consumption and will eventually disappear. For example, the foodstuff V procured as of the date D1 is used when creating the recommended menu A and the recommended menu B, and the inventory becomes zero as of the date D3. Therefore, as of the date D3, the foodstuff V cannot be used for the menu C.
In this way, the user terminal 1 recommends a menu suitable for the user U while considering at least the amount of the in-stock ingredients and the expiration date different for each ingredient. For each ingredient stored as inventory information in the inventory DB 401, a diagram showing a change (plan) of the inventory amount and the inventory amount based on the recommended menu as shown in FIG. 6 may be displayed on the user terminal 1. The change in the inventory amount is recognized by the user terminal 1 by image processing or the like based on the real menu notified to the real menu acquisition unit 108, which will be described later, and the photographs in the refrigerator or the like taken before and after the time when the real menu is made. You may learn and predict using the changes in the stock ingredients included in the photograph.

Next, a specific example of the menu recommendation process executed by the user terminal 1 will be described with reference to FIG. 7.
FIG. 7 is an image diagram showing a specific example of the menu recommendation process executed by the user terminal 1. In FIG. 7, in order to simplify the explanation, the menu recommended by the user terminal 1 is only dinner, and the recommended menu type is also one or two items.

In FIG. 7, the horizontal axis is time, the plurality of vertical axes are consecutive dates D1 to D6 (for example, July 1 to July 6), Y1 is the stock material, Y2 is the monthly budget, and Y2a is the monthly budget. It shows the budget amount (hereinafter referred to as "default budget") obtained by multiplying the daily amount and the number of days (3 days) until the next purchase date B2 (date D4). The date D4 is the current day.
Specifically, it is assumed that the date D1 corresponds to the purchase date B1 in which the user U purchases the ingredients. Then, when the user U purchases the foodstuff and the information about the foodstuff procured by the user U by the purchase is input to the user terminal 1, the inventory information acquisition unit 101 of the user terminal 1 obtains the stock information about the stocked foodstuff. To be acquired. That is, the inventory material Y1 as of the date D1 (purchase date B1) is stored in the inventory DB 401 as inventory information. Specifically, inventory information for each of a total of five types of ingredients, "shirataki", "carrot", "cabbage", "potato", and "pork belly", is stored in the inventory DB 401. The information about the foodstuffs procured by the user U by the purchase may be directly input by the user U to the user terminal 1, and the user terminal 1 is based on the photographs taken in the refrigerator or the like before and after storing the purchased foodstuffs in the refrigerator. May recognize changes in the stock ingredients contained in the photograph by image processing or the like, and acquire the change based on the recognition result.

As shown in FIG. 7, as of the date D1, the inventory amount of each of these five kinds of ingredients is indicated by polygons Y1a to Y1e, and will eventually disappear with daily use. For example, the polygon Y1a indicating the inventory amount of "Shirataki" was not used on the date D1, but since it was used on the date D2, it is out of stock at the time of the date D3.
Further, the remaining amount of the monthly budget Y2 as of the date D1 (hereinafter referred to as "remaining budget amount") is the amount after the purchase on the same day, that is, the amount obtained by subtracting the default budget Y2a from the monthly budget Y2 (Y2-Y2a). .. As the remaining budget amount, the user U may input the amount Y2a'(not shown) actually required for the purchase from the user terminal 1 and set it as (Y2-Y2a'). Alternatively, the remaining budget amount may be (Y2-Y2a'') by acquiring the amount Y2a'' (not shown) managed by the household account book management application on the user terminal 1 and actually required for purchase.

The element receiving unit 102 of the user terminal 1 receives one or more types of elements selected by the user U. In the example of FIG. 7, the case where the element "use-up" is selected by the user U will be described.
When the element reception unit 102 receives the element "use up", the menu recommendation unit 105 executes the following processing. That is, it is created based on the inventory information about shirataki noodles, carrots, onions, potatoes, and pork belly acquired by the inventory information acquisition unit 101, and the element "use-up" received by the element reception unit 102. Recommend the possible multi-day menu to User U.
Specifically, it is recommended to have a multi-day menu that prioritizes using up the ingredients with the shortest expiration date or the ingredients with the highest residual value within the range of the monthly budget Y2 of the user U.
In the example of FIG. 7, for the supper on date D1, "curry" using carrots, onions, potatoes, and pork belly is recommended.
For dinner on date D2, "nikujaga" using shirataki noodles, carrots, onions, potatoes, and pork belly is recommended. At the time of dinner on date D2, shirataki noodles, potatoes, and pork belly will be used up.
For dinner on date D3, "stir-fried vegetables" using carrots and onions is recommended. After that, at the time of dinner on date D3, the onions will be used up.
For dinner on date D4, "carrot soup" using the only carrot left in stock is recommended as a menu.
For dinner on date D5, since there are no ingredients in stock, "curry (thawed)", which is a frozen stock of curry prepared on date D1, is recommended as a menu.
The above is the menu recommended based on the inventory information as of the date D1 (purchase date B1).
Then, on the past dates D1, D2, and D3, when the user U selects the menu actually prepared as a dinner from the recommended menus displayed by the menu recommendation unit 105, the menu recommendation unit 105 serves as a real menu. In addition to notifying the real menu acquisition unit 108, the ingredients used in the real menu may be acquired from the menu DB 404, subtracted from the inventory amount of the inventory information related to the ingredients, and the inventory information may be updated. The inventory information is updated based on the photograph taken in the refrigerator or the like before and after the time when the supper is prepared, and the user terminal 1 recognizes the change in the inventory ingredients contained in the photograph by image processing or the like, and based on the recognition result. You may go there.

Further, on the day of date D4, user U wants to create "carrot saute" and "beef hamburger" which are menus other than "carrot soup" recommended as a menu for dinner on date D4 by user terminal 1. Supper. That is, suppose user U wants to change to another menu instead of the originally recommended menu. In such a case, the user U can change the menu by operating the user terminal 1.
By this operation, the designated menu reception unit 107 accepts "carrot saute" and "beef hamburger" from the menu recommendation unit 105 as designated menus. At this time, the designated menu reception unit 107 identifies the ingredients "carrot" and "ground beef" required to create "carrot saute" and "beef hamburger" from the menu DB 404, and the designated food reception unit 106 Notify to. The designated food receiving unit 106 searches the inventory DB 401, determines that "carrot" is an in-stock food and "ground beef" is an out-of-stock food, and notifies the menu recommendation unit 105. Menu recommendation department 105 presents that it is necessary to procure ground beef in order to make "beef hamburger steak".
Here, when the user U actually purchases the “ground beef” which is an out-of-stock ingredient, the inventory amount of the “ground beef” is indicated by the polygon Y1g. Registration of "ground beef" as inventory information in the inventory DB 401 accompanying the purchase of "ground beef" may be input by user U from user terminal 1, or is based on photographs taken in a refrigerator or the like before and after the time of purchase. Therefore, the user terminal 1 may recognize the change of the stocked foods contained in the photograph by image processing or the like, and perform the change based on the recognition result.

In addition, it is assumed that as of the date D4, which is "today", it was posted in the insert leaflet of the newspaper that "eel" will be sold at a bargain price "for today only". In this case, the special sale information acquisition unit 104 acquires the information as special sale information. The special sale information may be temporarily stored in the server 2 by an API connection from a Web service on the Internet, and may be acquired by the special sale information acquisition unit 104. The special sale information acquisition unit 104 may directly acquire the special sale information from the Web service on the Internet by API connection. The special sale information acquisition unit 104 may acquire the special sale information from the application that manages the special sale information running on the user terminal 1.
Then, the menu recommendation unit 105 displays that it is possible to procure the “eel” that is sold at a bargain price only on the date D4 based on the special sale information, and can confirm whether or not the “eel” has been purchased.
The method of presenting the ingredients based on the special sale information (“eel” in the example of FIG. 7) and the method of confirming whether or not the special sale ingredients are purchased are not particularly limited. For example, as shown in FIG. 8 to be described later, by displaying the special sale information in the display area H2 of the user terminal 1, it is shown that the special sale ingredients can be purchased, and a method of confirming the presence or absence of the purchase is adopted. You may. As shown in FIG. 11, by displaying the special sale information in the display area H6 of the user terminal 1, it is possible to show that the special sale ingredients can be purchased and to confirm the presence or absence of the purchase. good.
When the user U approves the purchase by using the predetermined method in response to the presentation by the menu recommendation unit 105 that the "eel" can be purchased, the menu recommendation unit 105 recommends it as a supper on date D5. The menu will be changed from the originally recommended "curry (thawed)" to "eel kabayaki". Alternatively, if you accept the designation of the ingredients you want to purchase (“eel” in the example of Fig. 7) in advance and obtain the special sale information including the ingredients you want to purchase, you can get the initially recommended menu without consenting to purchase (“Unagi”). In the example of FIG. 7, “curry (thawed)”) may be changed to a menu using ingredients included in the special sale information (“eel kabayaki” in the example of FIG. 7).
Here, when the user U actually purchases the “eel” which is a special sale ingredient, the inventory amount of the “eel” is indicated by the polygon Y1f. The registration of "eel" as inventory information in the inventory DB 401 accompanying the purchase of "eel" may be input by the user U from the user terminal 1, or based on the photographs in the refrigerator or the like taken before and after the time of purchase. The user terminal 1 may recognize a change in the stocked foods contained in the photograph by image processing or the like, and perform the change based on the recognition result.

In this way, the menu on date D4 was changed from "carrot soup" to "beef hamburger" and "sautéed carrot", and the menu on date D5 was changed from "curry (thawed)" to "eel kabayaki". Then, the menu recommendation unit 105 changes the budget.
That is, the budget on the purchase date B2 (date D4) will be changed due to the change in the menu. Specifically, as shown in FIG. 7, an additional budget Y2C due to the menu change will be added to the default budget Y2b on the purchase date B2 (date D4).
Therefore, the remaining budget amount as of the date D4 is obtained by Y2- (Y2a + Y2b + Y2c), and this remaining budget amount is the minimum amount of the predetermined monthly budget Y2 (hereinafter referred to as "minimum monthly budget"). If the product of the daily rate and the number of remaining days in the month is less than the amount obtained by subtracting the amount of in-stock ingredients converted into monetary value (hereinafter referred to as "inventory residual value"), the prescribed method was used. A warning is issued to user U. That is, when the following equation (1) holds, a warning to that effect is issued to the user U, assuming that the budget for purchasing the foodstuff is small.
Remaining budget amount <Minimum monthly budget / Monthly days x Remaining days-Inventory residual value ・ ・ ・ (1)

Next, a specific method for the user terminal 1 to recommend a menu for a plurality of days will be described.
FIG. 8 is an image diagram when the user terminal 1 of FIG. 3 displays the past real menu and the future recommended menu on the user terminal 1. In order to simplify the explanation, the menu recommended by the user terminal 1 is only dinner, and the recommended menu type is also one item.

As shown in FIG. 8, a monthly calendar is displayed in the display area H1 of the user terminal 1, and in each date column, a real menu and a menu for a multi-day dinner recommended by the user terminal 1 are displayed. It is displayed by the character button M or the graphic button C. Further, January 12, 2017, when "today" is displayed on the calendar, is the day when the user U is browsing the user terminal 1.
That is, the menu displayed in the column of the date before January 12, 2017, which is the current day, becomes a real menu, and the menu displayed in the column of the date after January 12, 2017 is recommended by the user terminal 1. It will be a multi-day menu.
In this way, the calendar displayed on the user terminal 1 can simultaneously display the real menu based on the past achievements of the user U and the future menu for a plurality of days recommended by the user terminal 1. Therefore, the user U can grasp the menu about the past and the future at a glance.

Specifically, for example, in the column of the date on which the real menu is displayed, the real menu on January 1, 2017 is "Osechi". Here, when the character button M displayed as "Osechi" is pressed by the user U, the ingredients actually used for creating "Osechi", the captured image of "Osechi", and the user U for "Osechi" Information such as evaluations and comments from family members is displayed.

Also, the real menu on January 2, 2017 is cup ramen. As described above, for the menu in which the user U can grasp the contents of the menu at a glance, the graphic button C can be displayed instead of the character button M.
In addition, not only fresh foods such as fruits and vegetables, meat, and fresh fish, but also preserved foods such as instant noodles and canned foods can be included in the inventory information.

In addition, in the column of the date on which the recommended menu is displayed, the menu on January 14, 2017 is "Yakiniku". Here, when the character button M displayed as "grilled meat" is pressed by the user U, information such as ingredients necessary for creating "grilled meat" and a recipe describing how to create "grilled meat" is displayed. To.
As a result, the user U can easily obtain information for creating the recommended menu (grilled meat). The user U presses the column of the date on which the recommended menu is displayed from the user terminal 1 to display the detailed screen (not shown) of the date, and changes the menu from "Yakiniku" to another menu. You may. By this operation, the designated menu reception unit 107 receives the designated menu from the menu recommendation unit 105.

The menu recommended for dinner on January 18, 2017 is cup ramen. Here, when the graphic button C indicating the cup ramen is pressed by the user U, information such as the inventory amount for each brand of the cup ramen can be displayed. As a result, the user U can easily grasp the inventory amount of the recommended menu (cup ramen).

In addition, the figure representing the 500-yen coin displayed in the column of January 5, 2017 indicates that the displayed date is the purchase date B. As a result, the user U can grasp at a glance the day when he / she bought the food and the day when he / she should go shopping. It should be noted that the user terminal 1 may make a proposal based on the inventory information and the monthly budget Y2 as to when the future purchase date B will be set in one month, or the user U may make a proposal based on his / her own schedule. You may also specify it. Further, the purchase date B proposed by the user terminal 1 may be modified by the user U according to his / her own schedule. To modify the purchase date B, you may drag the figure representing the 500-yen coin to move it to the position corresponding to the modified date, or press the date column corresponding to the purchase date B you want to modify. , The detail screen of the date may be displayed and the date of the "purchase date" event may be changed.

Further, as described above, the recommended menu can be changed to another menu according to the wishes of the user U. It is also possible to change to "eating out" instead of menu. In addition, the user U can specify in advance a specific day as the day of eating out.
As described above, for the day designated as the day of eating out by the user U, the character button G indicating eating out can be displayed in the date column on the calendar. For example, in the example of FIG. 8, January 8, 2017 is the day of eating out, and January 22, 2017 and January 28, 2017 are the days designated as the scheduled eating out dates. Here, when the character button G is pressed by the user U, the store name or genre of a specific restaurant that the user U has actually visited or plans to visit (for example, Japanese food, Western food, Chinese food, etc.) Etc. can be displayed. The specific store name and genre that you plan to visit may be recommended based on the set factors and the stores you actually visited.

Further, in the display area H2 of the user terminal 1, information such as inventory information on the day when the user U is browsing the user terminal 1 is displayed for each display item.
Specifically, "foodstuff stock" which is a display item indicating inventory information, and "when the day when the user U is browsing the user terminal 1 corresponds to the purchase date B, the display item which indicates the information". User U browses user terminal 1 for "Today's purchase", "Food cost calculation" which is a display item indicating the remaining budget amount of monthly budget Y2, and "Special sale / coupon" which is a display item indicating special sale information. "Today's menu", which is a display item showing information about the menu of the day, is displayed.

In the example of FIG. 8, among the display items displayed in the display area H2, the “foodstuff stock” includes a figure indicating carrot and the character “× 2”, and a figure indicating pork loin and the character “200 g”. , The character button S represented by the characters "More ..." is displayed.
As a result, the user U can grasp that he / she has at least two "carrots" and 200 g of "pork loin" as inventories. Further, the user U can display the amount of in-stock ingredients other than "carrot" and "pork loin" by pressing the character button S represented by the character "More ...".

Among the display items displayed in the display area H2, "Today's purchase" includes the amount of "¥ 500", the figure showing the horse mackerel of fresh fish, the letters "x2", and the figure showing the cabbage of fruits and vegetables. The characters "x 1/2" are displayed.
As a result, the user U understands that the budget for today's shopping is "¥ 500" and that the ingredients to be purchased today are 2 "horse mackerel" and 1/2 "cabbage". be able to.

Among the display items displayed in the display area H2, the amount of "¥ 9,500" and the character button T represented by the characters "view the budget performance graph" are displayed in the "food expense balance". ..
As a result, the user U can grasp that the remaining budget amount of the monthly budget Y2 is "¥ 9,500". Further, the user U can display the purchase record for the monthly budget Y2, although not shown, by pressing the character button T represented by the characters "view the budget record graph".

Among the display items displayed in the display area H2, the "sale / coupon" displays a figure showing eel kabayaki, an amount of "¥ 1,000", and a button K consisting of the characters "purchase / acquire". Has been done.
As a result, the user U can grasp that "eel kabayaki" is "1,000 yen" per pack as special sale information. In addition, the user U changes the menu today or the next day or later to "eel kabayaki" by pressing the button K consisting of the characters "purchase / acquire". As mentioned above, if the recommended menu is changed, the remaining budget amount will also be changed.

Among the display items displayed in the display area H2, in the "today's menu", the characters "carrot soup" and the character button L composed of the characters "change" are displayed.
As a result, the user U can grasp that today's menu is "carrot soup". User U can also change today's menu from "carrot soup" to another menu by pressing the letter button L consisting of the letters "change".
The user terminal 1 displays the menu for a plurality of days by using the above-mentioned specific method. As a result, the user U can confirm the menu for a plurality of days.

Next, with reference to FIG. 9, the achievement degree calculation process executed by the user terminal 1 having the functional configuration of FIG. 3 will be described.
FIG. 9 is a flowchart illustrating a flow of achievement degree calculation processing executed by the user terminal 1 of FIG.

As shown in FIG. 9, the user terminal 1 executes the following series of processes.
In step S21, the real menu acquisition unit 108 acquires the real menu.
In step S22, the comparison unit 109 compares the recommended menu with the real menu based on a predetermined comparison standard determined for each of one or more types of elements. As another example of the comparison unit 109, a constant numerical value to be achieved set for each predetermined period (for example, one day) may be compared with a numerical value calculated from the real menu for the predetermined period.
In step S23, the achievement degree calculation unit 110 calculates the achievement degree for each of one or more types of elements based on the comparison result by the comparison unit 109. This completes the achievement calculation process.
By executing the series of processes as described above by the user terminal 1, the user U can easily grasp the degree of achievement of the real menu with respect to the recommended menu.

Next, a specific method for the user terminal 1 to display the achievement level for each element calculated by the achievement level calculation process shown in FIG. 9 will be described.
FIG. 10 is a graph (hereinafter referred to as “achievement level graph”) as an example of a specific method for displaying the achievement level for each element calculated by the user terminal 1 of FIG.

As shown in FIG. 10, in the achievement graph, the horizontal axis represents the year and month, and the vertical axis represents the achievement. The three polygonal lines plotted on the achievement graph all indicate the elements P1 to P3 specified by the user U. Further, in the example of FIG. 10, the achievement degree of each of the elements P1 to P3 is displayed as a normalized value so that the maximum value is “100” and the minimum value is “0”.
Specifically, for example, three elements, an element P1 of "nutrition balance", an element P2 of "use-up", and an element P3 of "preference" are designated as fixed elements, and based on these three elements P1 to P3. It is assumed that the menu for 7 months from January to July is recommended by the user terminal 1.
In this case, the recommended menu and the real menu are compared, or a certain numerical value to be achieved set for each predetermined period is compared with the numerical value calculated from the real menu for the predetermined period. Therefore, the degree of achievement for each of the elements P1 to P3 can be calculated on a monthly basis. In the example of FIG. 10, the horizontal axis is displayed in units of months, but it may be displayed in units of days, years, quarters, or any other period.

Specifically, the achievement level of element P1 (nutrition balance) was 80 in January 2017, but the achievement level was 50 or less from February to April 2017, and then from May 2017 to 7 The month has maintained a level of achievement of 60 or higher. That is, the user U can at a glance grasp that the real menu is nutritionally balanced.
In addition, element P2 (use-up) had an achievement level of 50 in January 2017, and although it fluctuates depending on the month thereafter, it has consistently maintained an achievement level of 50 or more, and in July 2017, The achievement level is 80, which is the highest among the three elements (elements P1 to P3). That is, the user U can at a glance grasp that the stock ingredients are efficiently and economically used up by the real menu.
In addition, the achievement level of element P3 (preference) was 10 in January 2017, and even after that, the achievement level has consistently remained below 30 although it fluctuates slightly depending on the month. In addition, although it has been on an upward trend since May 2017, as of July 2017, the achievement level is 30, which is the lowest among the three elements (elements P1 to P3). That is, the user U can at a glance grasp that the real menu is not a menu that suits the taste of the user U.
As a result, the user U can reflect on the points that should be reflected and maintain the good points in the future, which can be utilized in the decision of the menu in the future.

Next, a specific method in which the user terminal 1 recommends information necessary for the user U to make a purchase will be described.
FIG. 11 is an image diagram showing an example of a specific method of recommending menus from bargain sale information and inventory information.
