  When the complete button 1104 is clicked, the inventory ingredients setting screen is closed, and the purchased ingredient list creation unit 114 reflects the input information regarding inventory ingredients in the inventory ingredient information table 123 shown in FIG. 6 (S304).

  The process of reflecting the information set in the inventory food information table 123 in the purchased food list 124 will be described in detail later with reference to FIG.

  Next, the purchase schedule creation unit 115 acquires sales information from the sales company server 10 via the network interface 104 and stores it in the sales information table 125 (S305).

  Next, the purchase schedule creation unit 116 creates a purchase schedule that determines when and how much food should be purchased based on the updated sales information table 125 (S306).

  Next, the process of reflecting the stock ingredient information in the purchased ingredient list will be described with a specific example using FIG.

  The process of reflecting the stock ingredient information in the purchased ingredient list is a process performed in step S304 of FIG.

  First, attention is focused on the ID0001 “potato” recorded in the first record of the inventory food information table 123 shown in FIG. 6 (S401).

  Next, it is confirmed whether or not there are potatoes in the purchased ingredient list 124 shown in FIG. 4A (S402).

  In the purchased food list 124 shown in FIG. 4A, since four potatoes are scheduled to be used on August 3, next, it is confirmed whether or not the potatoes of the food are within the expiration date (S403).

  The expiration date for potatoes is August 11, which is indicated by the value of the expiration date 1905 in the inventory food information table 123 shown in FIG. Therefore, August 3 scheduled to be used is within the expiration date, and since the potatoes in the inventory ingredient list can be used on this day, four potatoes of August 3 are deleted from the purchased ingredient list 124 (S404).

  Now that the processing of one record has been completed, it is next determined whether or not there is another stock food (S405).

  In the example of the stock food information table 123 shown in FIG. 6, attention is paid to the next “rice” of ID0002 (S406).

  When it is confirmed whether or not the rice is in the purchased food list 124 shown in FIG. 4A (S402), it is on August 2, 3, 4, and 9 to 14, each of which is 2 g (300 g ) It is understood that a total of 2.7 kg is planned to be used. Next, it is confirmed whether it is within the expiration date (S403).

  The expiration date of rice is August 14 as indicated by the value of the expiration date 1905 of the inventory food information table 123, and 1.5 kg of rice indicated by the number 1904 can be used within the expiration date on August 2. The third day, the fourth day, the ninth day, and the tenth day are deleted from the purchased ingredient list 124 shown in FIG. 4A (S404).

  Similarly, “Nasu” of ID0003 and 0004 exists in the column of August 3 in the purchased food list 124 shown in FIG. 4A, and the date is the expiration date (one is August 7 and three are August 8), and is deleted from the purchased food list 124.

  In this way, when the information in the inventory food information table shown in FIG. 6 is reflected, the purchased food list 124 becomes as shown in FIG. 4B.

  Next, the process of creating a purchase schedule will be described using a specific example with reference to FIG.

  The process for creating the purchase schedule is a process performed in step S306 in FIG.

  Here, an example will be described in which the user purchases the ingredients on the purchased ingredient list on August 1 and August 2 on the previous day of the purchased ingredient list. Further, the sales information table 125 in FIG. 7 represents the latest sales information in the sales company server at that time.

  First, the purchase schedule creation unit 116 focuses on “yakisoba noodles” of the first ingredient on August 1 in the purchased ingredient list 124 shown in FIG. 4B (S501). Next, when it is confirmed whether or not the focused food is not scheduled to be used on another day (S502), the noodles for yakisoba are included only in this day in the purchased food list 124.

  Next, the expiration date of “yakisoba noodles” is confirmed (S503). Referring to the expiration date information table of FIG. 9, the expiration date of “yakisoba noodles” is 10 days.

  Next, the product corresponding to the ingredient “yakisoba noodle” is searched from the ingredient / product correspondence table 126 shown in FIG. In this case, “yakisoba noodle 4 meal pack” of product ID 0012 is searched. Then, it is confirmed whether or not a plurality of packs having different unit prices are sold (S504). If there are multiple types of packs, the process proceeds to S505, and it is determined which pack is best to purchase. However, since “noodles for yakisoba” has only one type of pack, select the product of this pack ( S506), the ingredient “yakisoba noodles” is deleted from the purchased ingredients list 124, and the product “yakisoba noodles 4 meal pack” is registered as a purchase in the purchase schedule shown in FIG. Transition to processing (S507, S508).

  Next, we will focus on “pork pork”. When it is confirmed whether or not “pork rose meat” is scheduled to be used on another day (S502), the purchase lists including “pork rose meat” are August 1, 9, and 12. . Next, the expiration date is acquired with reference to the expiration date information table of FIG. 9 (S503). Referring to the expiration date information table 122 of FIG. 9, it can be seen that the expiration date of “pork pork” is 2 days.

  Next, the product corresponding to the ingredient “pork rose meat” is searched from the ingredient / product correspondence table 126 shown in FIG. In this case, the product ID 0009 “Japanese pork belly meat 200 g”, the product ID 0010 “Japanese pork belly meat 400 g”, and the product ID 0011 “Japanese pork belly meat 600 g” are searched. Then, with reference to the sales information table 125 of FIG. 7, it is confirmed whether or not a plurality of packs with different unit prices are sold (S504). As for products corresponding to “pork belly meat”, “Japanese pork belly meat 600 g” of product ID 0011 is out of stock, “ID pork belly domestic 200 g” of product ID 0009, and “pork belly meat domestic 400 g” of product ID 0010 You can see that the item is in stock and available. However, since all the unit prices are the same, “400g domestic pork belly” of product ID 0010, which is a pack of 400 g, which is the amount used on the day of interest, is selected as one purchase (S506), FIG. This is reflected in the purchase schedule shown in FIG.

  Next, attention is paid to the “cabbage” of food (S501). If the date of the ingredient purchase list 121 including “cabbage” is confirmed, it will be August 1, 9, and 12 (S502). The expiration date is 10 days (S503).

  Next, the product corresponding to the ingredient “cabbage” is searched from the ingredient / product correspondence table 126 shown in FIG. 8. In this case, “Cabbage (Okayama)” with the product ID 0001 and “Cabbage 1/2 (Okayama)” with the product ID 0002 are searched. Then, referring to the sales information table 125 in FIG. 7, if it is confirmed whether packs with different unit prices are sold, there are 1/2 and 1 pack (S504). Attention is paid (S505). The amount required for the menu on August 1 is ½, but the cabbage is also used for the menu on August 9, which is within 10 days, the expiration date of cabbage. Therefore, even if purchased on July 31, it is determined that it can be consumed within the expiry date of August 10 (S507), and one “cabbage (Okayama)” of product ID 0001 is purchased on July 31. Thus, it adds to the purchase schedule 127.

  Then, the registration of 1/2 cabbage on August 1 and 1/2 cabbage on August 9 is deleted from the purchased food list 124 (S509).

  Next, pay attention to “beef for curry” on August 2 (S502). When the date of the ingredient purchase list 121 containing “curry beef” is confirmed, it is only August 2 (S502). Further, the expiration date is 2 days (S503). The product corresponding to the ingredient “curry beef” is searched from the ingredient / product correspondence table 126 shown in FIG. In this case, product ID 0020 “Beef Australian Curry for Curry 400 g”, product ID 0021 “Beef US Curry for Curry 400 g”, product ID 0022 “Domestic Beef for Curry 400 g”, product ID 0023 “Japanese Beef for Curry Beef 400 g” "Is searched. Then, referring to the sales information table 125 in FIG. 7, one pack of “400g beef Australian curry for curry” with the lowest product ID 0020 is purchased (S504, S506).

  Next, attention is paid to the “carrot” of the food (S502). When the date on which “carrot” is used is confirmed in the food material purchase list 121 of FIG. 4B, it can be seen that it is August 2, 12, and 13 (S502). Referring to the expiration date information table 122 of FIG. 9, the expiration date of “carrot” is 10 days (S503).

  The product corresponding to the “carrot” of the food is searched from the food / product correspondence table 126 shown in FIG. In this case, “carrot 2-pack” of product ID 0003, “carrot 4-pack” of product ID 0004, and “carrot 6-pack” of product ID 0005 are searched.

  Next, when it is confirmed whether or not a plurality of product packs having different unit prices in the sales information table 125 in FIG. 7 are sold, it is found that there are four packs and six packs (S504). Here, attention is paid to products of “carrot 6-pack”, which is the cheapest 6-pack (S505). Next, when the 6-pack is purchased, it is confirmed whether or not it can be consumed within the expiration date (S507). If purchased on August 1, the expiration date is August 10. On August 2, 4 bottles are consumed and 2 bottles are left. Next, the carrot is consumed on August 12, and the expiration date of August 10 is passed. Since it cannot be consumed within the expiry date, attention is now focused on four packs with a low unit price (S508). In the case of this pack, since it will be used up on August 2, it can be consumed within the expiry date, so that it is registered in the purchase schedule that one “carrot 4 pack” of product ID 0004 is purchased. (S509).

  In this way, the purchase schedule 127 of ingredients used on August 1 and August 2 created based on the purchase ingredient list 124 shown in FIG. 4B is as shown in FIG. The created purchase ingredient list 124 is as shown in FIG. 4C.

  The purchase schedule 127 and the purchased food list 124 are stored in the auxiliary storage device 109 after the update. And according to this purchase schedule, the purchase process part 109 performs the purchase of foodstuffs every day.

  Next, the purchase processing of foodstuffs is demonstrated using FIG.

  The food purchase process is a process performed in step S207 of FIG.

  The purchase schedule 127 is created on the premise that there is an inventory of registered types and quantities of ingredients, and that the ingredients can be purchased from the sales information obtained from the sales company at the time of creating the schedule. However, it is possible that the remaining ingredients have already been used, and that the freshness is lower than expected, making it unusable. In addition, there may be a case where a product to be purchased is out of stock at the point of sale and cannot be obtained. Considering such a case, at the time of purchase, the inventory ingredients are checked again and the sales status of the products of the ingredients scheduled to be purchased is checked.

  First, the purchase processing unit 109 displays the inventory food information setting screen shown in FIG. 21 on the display device 101 via the UI control unit, and checks the inventory food (S601). If the displayed inventory information is different from the actual inventory, the user clicks the correction button 1102 to register the correction.

  If there is a change in the stock ingredients (S602), the process of reflecting the input information on the stock ingredients in the stock ingredient information table 123 (the process of S304) is performed again (S603). The process of acquiring sales information (process of S305) is performed (S604), and the process of creating a purchase schedule (process of S306) is performed (S605).

  Next, the purchase processing unit 109 performs confirmation processing of whether or not the product can be purchased (S606).

  Details of the confirmation process of whether or not the product can be purchased will be described later with reference to FIG.

  Next, as a result of the confirmation process of whether or not the product can be purchased, the display device 101 displays the food material purchase setting screen shown in FIG. 20A (S607). Here, in the purchased product list 1310, information on products purchased on August 1st is displayed today. In the figure, “400g Australian beef for curry”, “4 carrot packs”, and “4 onions from Awaji” are displayed as products to be purchased.

  When the user purchases a product having the content displayed in the purchase product list 1310 according to the purchase schedule (S608), the purchase button 1301 is selected, and the purchase processing unit 109 executes the purchase process (S612). Purchasing processing is performed according to the normal electronic transaction procedure, such as confirmation of the content of the purchased product, confirmation of the delivery destination, confirmation of purchase intention, and selection of payment means (credit card, transfer, cash on delivery), etc., but details are omitted. .

  When the user wants to select another product without following the purchase schedule, when the user selects the product in the purchased product list 1310 by clicking with a pointing device such as a mouse, a selection frame 1311 is displayed. A search button 1302 is clicked. Thereby, the purchase processing unit 109 causes the display device 101 to display the related product selection screen illustrated in FIG. 22 via the UI control unit. In the figure, “400g beef Australian beef for curry” is displayed as the selection frame 1311.

  When a return button 1501 is clicked, the related product selection screen is closed and the food material purchase setting screen shown in FIG. 20A is displayed. The product change button 1502 is a button for instructing to replace the product selected by the user with the original product. The original product display column 1503 is a column for displaying the original product name selected on the ingredient purchase setting screen shown in FIG. 20A. The related product list 1510 is a list that displays products related to the original product.

  The system acquires related product information of the original selected product (S609) and displays it in the related product list 1510.

  In the example shown in FIG. 22, “400g Australian beef curry for curry” is displayed in the related product list 1510 as the original product, and the related products are “400g US beef for curry”, “for curry” "Domestic 400g beef" and "Japanese beef black beef 400g for curry" are displayed.

  The search for related products refers to the food / product correspondence table 126 and searches for products having the same category as the original product. In this example, the category of “curry beef Australian 400 g” of the original product ID 0020 is “curry beef US 400 g”, the product ID 0021 “curry beef US 400 g”, and the product ID 0022 “curry beef”. “Domestic 400 g” and product ID 0023 “Japanese curry beef black beef 400 g” belong to the same category.

  When the user changes the original product (S610), the instruction input unit 102 selects a related food item in the related food list 1504, and the UI control unit 111 displays a selection frame 1511 accordingly. When the product change button 1502 is selected in this state, the purchase processing unit 109 changes the product displayed in the original product display field 1503 to the selected product, and corrects the purchase schedule (S611). Then, the UI control unit 111 returns to the food material purchase setting screen shown in FIG. 20A.

  Then, purchase processing is performed by selecting the purchase button 1301 on the food material purchase setting screen (S612).

  In this system, the cheapest product is selected, but if the user wants to select a product with good quality ingredients even if the user is expensive, this system searches for related products and prompts the user for this system. Can be compared with the food presented.

  Next, processing for confirming whether or not a product can be purchased will be described with reference to FIG.

  The confirmation process of whether or not the product can be purchased is a process performed in step S602 in FIG.

  First, sales information is acquired from the sales company server 10 via the network interface 104, and the sales information table 125 is updated (S701).

  Next, it is confirmed whether or not the products in the purchased product list 1310 scheduled to be purchased on that day can be purchased (S702).

  If all the items in the purchased item list 1310 can be purchased, the process ends.

  If there is a product that cannot be purchased, it is checked whether there is a substitute product (S703). The substitute product here is a product in which the category column of the food / product correspondence table 126 shown in FIG. 8 is the same as the product that cannot be purchased. Here, a product of a different number of packs with a product related to the same food material, or a product related to a food material of the same kind and having a different production area or variety is a candidate to be a substitute product for the product. When there is no substitute product that can be purchased, the purchase processing unit 109, as shown in FIG. 20B, indicates that the planned foodstuff could not be purchased in the display device 101 via the UI control unit and there was no substitute product. A message recommending the menu change is displayed and the process ends (S706).

  If an alternative product is found, the product with the lowest unit price is selected (S704).

  For example, it is assumed that “stock of Australian beef for curry 400 g” is out of stock in the purchased product list 1310 on the food material purchase setting screen shown in FIG. 20A. At that time, as an alternative product, the “curry beef Australian 400 g” and the “curry beef domestic 400 g” that are the same as the “curry beef Australian 400 g” in which the category column of the food / product correspondence table 126 cannot be purchased, “400g Japanese beef for curry” is searched, and among these, “400g US beef for curry” having the lowest unit price is selected (S705).

  Next, if there are other non-purchasable products, the same processing is performed for those products (S707, S708). In this way, all the products scheduled to be purchased in the purchased product list 1310 are checked.
