<Order of procurement process>
Here, the order of the procurement steps in the procurement methods shown in FIGS. 6 and 7 will be described.

FIG. 11 is a diagram illustrating a part of the procurement methods shown in FIGS. 6 and 7 and the procurement process carried out by each procurement method.

In FIG. 11, as procurement methods, "first home cooking", "third home cooking", "fourth home cooking", "sixth home cooking", and "delivery" are used. It is shown. The "second home cooking", "fifth home cooking", "lunch box", and "restaurant" are omitted.

The "first home cooking" is when the user cooks food at home using the raw materials in stock. The "first home cooking" procurement process is arranged in the order in which it is carried out. The process "preparation" (F1), which indicates the preparation work of the cooking process of making food from raw materials, and the cooking process from raw materials are made. It has a process "cooking" (F2) indicating a cooking (heat treatment) operation in the cooking process. The cooking process for making a dish differs depending on the dish and may be set based on the recipe information.

The "third home cooking" is a case where the user goes to the store to purchase the raw materials and the user cooks the food at home. The "third home cooking" procurement process, when arranged in the order in which it is carried out, is the process "movement" (F3), which indicates the movement from home to the store, and the process, which indicates the work of purchasing the raw materials for cooking in the store. "Purchase" (F4), the process "Move" (F5) indicating the movement from the store to the home, and the process "Preparation" (F6) indicating the preparation work in the cooking process of cooking from raw materials. It has a step "cooking" (F7) indicating a cooking (heat treatment) operation in a cooking process of making a dish from raw materials.

For the "fourth home cooking", the delivery of raw materials is ordered from the store using the Internet or the like. Then, the store delivers the raw materials to the user's home, and the user cooks the food from the raw materials at home. The process of procuring the "fourth home-cooked food" is the process "ordering" (F8), which indicates the work of ordering the delivery of raw materials from the store and completing the preparation for delivery when arranged in the order in which they are carried out. , The process "delivery" (F9) indicating the work of the store delivering the raw materials to the user's home, and the process "preparation" (F10) indicating the preparation work of the cooking process of cooking from the raw materials, and from the raw materials It has a process "cooking" (F11) indicating a cooking operation in the cooking process of making a dish.

In the "sixth home cooking", the delivery of semi-processed products is ordered from the store using the Internet, etc., the store delivers the semi-processed products to the user's home, and the user cooks the semi-processed products at home. If this is the case. The "sixth home cooking" procurement process includes the process "ordering" (F12), which indicates the work of ordering the delivery of semi-processed products from the store in chronological order and the store completing the preparation for delivery. The store has a step "delivery" (F13) indicating the work of delivering the semi-processed product to the user's home, and a process "cooking" (F14) indicating the cooking work of the semi-processed product.

“Delivery” is a case where an order is placed for delivery of a cooked dish (finished product) to a store using the Internet or the like, and the store delivers the finished product to the user's home. The “delivery” procurement process includes the process “ordering” (F15), in which the delivery of the finished product is ordered from the store in chronological order and the store completes the preparation for delivery, and the store uses the finished product as the user. It has a process "delivery" (F16) indicating the work of delivering to the home.

In addition, in the "first home cooking", the "third home cooking", and the "fourth home cooking", since the cooking is made from the raw materials, the preparation process is taken into consideration. On the other hand, when cooking from semi-processed products such as "sixth home cooking", the preparation time is short and the cooking time is the main, so the preparation process does not need to be considered. Good. In addition, if it is “delivery”, the finished product arrives, so it is not necessary to consider the cooking process.

In FIG. 8, the procurement process evaluation unit 47 includes all types of dishes included in any of all menus of the menu candidates set by the menu candidate setting unit 44, and procurement set by the procurement method candidate setting unit 46. For the combination with all kinds of procurement methods of the method candidates, each set is set as the food to be evaluated and the procurement method to be evaluated. Then, the menu candidate setting unit 44 determines the time (required time) for each procurement process (each procurement process for implementing the evaluation target procurement method) when procuring the evaluation target dish by the evaluation target procurement method. Evaluate cost and labor (labor).

<Structure example of procurement process evaluation department>
FIG. 12 is a block diagram showing a configuration example of the procurement process evaluation unit 47.

The procurement process evaluation unit 47 includes an evaluation target setting unit 71, a move destination store candidate setting unit 72, a supplier store candidate setting unit 73, a move process evaluation unit 74, a purchase process evaluation unit 75, an order process evaluation unit 76, and an order process evaluation. It has a delivery process evaluation unit 78, a preparation process evaluation unit 79, and a cooking process evaluation unit 80.

The evaluation target setting unit 71 includes all kinds of dishes included in any of all the menus of the menu candidates set by the menu candidate setting unit 44, and all the procurement method candidates set by the procurement method candidate setting unit 46. About the combination with the type of procurement method, one set at a time is set as the food to be evaluated and the procurement method to be evaluated. Then, the evaluation target setting unit 71 procures the food to be evaluated by the evaluation target procurement method, that is, the move destination store candidate setting unit 72, the ordering party store candidate setting unit 73, the move process evaluation unit 74, and the purchase. Notify all of the process evaluation unit 75, the ordering process evaluation unit 76, the ordering process evaluation unit 77, the delivery process evaluation unit 78, the preparation process evaluation unit 79, and the cooking process evaluation unit 80.

In the destination store candidate setting unit 72, the procurement method to be evaluated is "third home cooking", "fifth home cooking", "lunch box", or "restaurant" shown in FIGS. 6 and 7. In the case of ", the destination store where the user purchases ingredients or lunch boxes (side dishes) or the destination store for eating out is selected as the destination store candidate. If the procuring method to be evaluated is "third home cooking" or "fifth home cooking", the destination store candidate selects the ingredients (insufficient ingredients) of the cooking to be evaluated. It is a store where you can buy supermarkets, convenience stores, etc. When the procuring method of the evaluation target is "bento", the destination store candidate is a purchase store such as a bento specialty store, a supermarket, or a convenience store that sells the food to be evaluated. When the procurement method of the evaluation target is "restaurant", the destination store candidate is a restaurant or the like that provides the food to be evaluated.

Further, the move destination store candidate setting unit 72 refers to the departure position designated by the user or the user's home position when selecting the move destination store candidate. When the departure position when heading to the destination store is other than the home position, the user specifies, for example, information on the departure position (address, etc.). The destination store candidate setting unit 72 acquires the information of the departure position specified by the user from the input information acquisition unit 42. When the user does not particularly specify the departure position, the destination store candidate setting unit 72 sets the departure position as the home position and acquires the home address from the user information of the user information storage unit 31. When the user sets the current position as the departure position, the GPS information of the information terminal is transmitted to the information generation server 12 as the departure position information, and the GPS information is acquired by the destination store candidate setting unit 72. May be good.

Further, the destination store candidate setting unit 72 selects, for example, a destination store candidate from the stores existing within the range of the travel distance predetermined with respect to the departure position of the user. The destination store candidate setting unit 72 may select the transfer destination store candidate using the map data stored in the storage unit 23, or may use the map search service of the website or the like. Good. Further, the store that the user normally uses may be specified in advance by the user and registered as user information in the user information storage unit 31. In that case, the destination store candidate setting unit 72 may preferentially select the store registered in the user information as the destination store candidate.

In addition, when selecting a destination store candidate, the destination store candidate setting unit 72 sets only the stores that are open on the date (day of the week) and the time zone when the food to be evaluated is procured as the destination store candidate. To do. The date (day of the week) and time zone for procuring the food to be evaluated are set based on the user's specifications. For example, the user specifies a date and time to start preparing a meal and a date and time to start preparing a meal. As a result, the date and time from the date and time when the meal preparation is started to the date and time when the meal is started are set as the date and time when the food is procured. In addition, the destination store candidate setting unit 72 acquires information on the calendar service (schedule management service) used by the user from the environment information acquisition unit 48 in FIG. 8, and grasps the user's time restrictions and schedule. Then, the date and time zone that is convenient for the user may be the date and time zone that uses the destination store.

If there is only one store that can be a destination store candidate, the destination store candidate setting unit 72 sets that store as the destination store candidate. When there is no store that can be a candidate for a destination store, the destination store candidate setting unit 72 excludes the procurement method to be evaluated from the evaluation target and excludes it from the procurement method candidates for the food to be evaluated. Further, when there are a plurality of stores that can be candidates for the destination store, the destination store candidate setting unit 72 indicates that the store has the shortest travel distance from the departure position or the home position, the store with the lowest charge, or the user. Set the store with the highest frequency of use as a destination store candidate. When there are a plurality of stores that can be candidates for the destination store, the destination store candidate setting unit 72 may set the plurality of stores as the destination store candidates. When a plurality of destination store candidates are set in the destination store candidate setting unit 72, the evaluation target setting unit 71 sets the case where each of the plurality of destination store candidates is used as a separate evaluation target procurement method. ..

In the supplier store candidate setting unit 73, the evaluation target procurement methods set in the evaluation target setting unit 71 are the “fourth home cooking” and the “sixth home cooking” shown in FIGS. 6 and 7. Or, in the case of "delivery", the store where the user orders the delivery of cooking ingredients or the delivery is selected as the ordering store candidate. When the procuring method to be evaluated is "fourth home cooking" or "sixth home cooking", the supplier store candidate selected by the supplier store candidate setting unit 73 is the evaluation target dish. It is a store that provides a service to deliver materials (insufficient materials) to the user's home. When the procurement method of the evaluation target is “delivery”, the store provides a service of delivering the food to be evaluated to the user's home.

When the supplier store candidate setting unit 73 selects the supplier store candidate, if the procurement method to be evaluated is "fourth home cooking" or "sixth home cooking", For example, when the food delivery service of the website is used and the procurement method to be evaluated is “delivery”, for example, the delivery service of the website is used.

Further, when selecting the supplier store candidate, the supplier store candidate setting unit 73 sets only the stores that are open on the date (day of the week) and the time zone when the food to be evaluated is procured as the move destination store candidate. To do. Since the date and time zone for procuring the food to be evaluated are the same as in the case of the destination store candidate setting unit 72, the description thereof will be omitted.

If there is only one store that can be a candidate for a supplier store, the supplier store candidate setting unit 73 sets that store as a candidate for the supplier store. When there is no store that can be a candidate for a supplier store, the supplier store candidate setting unit 73 excludes the procurement method to be evaluated from the evaluation target and excludes it from the procurement method candidates for the dish to be evaluated. Further, when there are a plurality of stores that can be candidates for the supplier store, the supplier store candidate setting unit 73 uses the store with the cheapest price, the store that delivers the ingredients or dishes to the home at the earliest, or the user. Set the store with the highest frequency as a candidate store for the supplier. When there are a plurality of stores that can be the ordering party store candidates, the ordering party store candidate setting unit 73 may set those plurality of stores as the ordering party store candidates. When a plurality of supplier store candidates are set in the supplier store candidate setting unit 73, the evaluation target setting unit 71 sets the case where each of the plurality of supplier store candidates is used as a separate procurement method for the evaluation target. ..

In the moving process evaluation unit 74, the procurement method to be evaluated is "third home cooking", "fifth home cooking", "lunch", or "eating out" shown in FIGS. 6 and 7. In some cases, the time, cost, and labor required for the procurement process "movement" included in the procurement method to be evaluated are evaluated.

When the procurement method to be evaluated is "third home cooking", "fifth home cooking", or "lunch", the procurement method to be evaluated is moved from the departure position specified by the user. There are two processes, the procurement process "move" corresponding to the movement to the destination store candidate set by the destination store candidate setting unit 72, and the procurement process "move" corresponding to the movement from the destination store candidate to the home. included. When the procurement method to be evaluated is "restaurant", only one procurement process "move" corresponding to the movement from the departure position specified by the user to the destination store candidate set by the destination store candidate setting unit 72 is available. Is included.

The moving process evaluation unit 74 uses, for example, map data (not shown) stored in the storage unit 23, or a map search service on a website, etc., to include a procurement process included in the procurement method to be evaluated. Estimate the time required for each "movement". Further, the moving process evaluation unit 74 sets the moving means of the user when estimating the time required for the procurement process “moving”. For example, the user's moving means may be specified by the user, or may be registered in advance as user information in the user information storage unit 31 (FIG. 2). Transportation means include cars (private cars, taxis, etc.), buses, bicycles, and walking. Further, by storing the time required for the procurement process "movement" performed by the user in the past as history information in the history information storage unit 33, the movement process evaluation unit 74 refers to the history information and performs the procurement process "movement". The time required for "movement" may be estimated.

In addition, the movement process evaluation unit 74 estimates the cost and labor (labor) required for the procurement process “movement”. The cost required for each procurement process is a fee (expense) paid by the user in each procurement process, and the cost required for the procurement process "movement" is the total fare when using a transportation means that requires a fare.

The labor is, for example, the product of a coefficient representing the amount of labor (labor) of the work content of each procurement process and the time required for each procurement process. The labor required for the procurement process "movement" is the product of a coefficient (called a labor coefficient) representing the amount of labor required for the movement and the time required for the procurement process "movement". For example, in the procurement process "movement", the labor coefficient is set to a larger value when walking than when using a car.

When the procurement method to be evaluated is "third home cooking", "fifth home cooking", or "lunch", the purchase process evaluation unit 75 includes procurement included in the procurement method to be evaluated. Evaluate the time, cost, and effort required for the process "purchase".

The procurement process "purchase" is from arriving at the destination store candidate set by the destination store candidate setting unit 72 to purchasing the target material or lunch box (side dish) and moving out of the destination store candidate. Represents a process.

For example, the purchase process evaluation unit 75 requires the procurement process "purchase" in consideration of the degree of congestion according to the date and time zone when the destination store candidate is used with respect to the standard time required for purchase at the store. Estimate the time. The purchase process evaluation unit 75 acquires information on the degree of congestion according to the date and time zone in which the destination store candidate is used from the website related to the destination store. However, the information on the degree of congestion according to the date and time zone in which the destination store candidate is used may be predetermined general information such that the store is crowded in the evening time zone.

In addition, the purchase process evaluation unit 75 determines the types of ingredients for making the food to be evaluated and the type of ingredients for making the food to be evaluated when the procurement method to be evaluated is the "third home cooking" or the "fifth home cooking". The cost required for the procurement process "purchase" is estimated by referring to the quantity and the type and quantity of the material (material in stock) stored in the user's home.

The purchase process evaluation unit 75 determines the type and amount of ingredients for making the dish to be evaluated, the recipe information of the recipe information storage unit 32 in FIG. 2, the number of people who eat the meal specified by the user, or the amount of menu. Ask based on (for some people). The purchase process evaluation unit 75 obtains the type and amount of the material in stock from the inventory information from the environmental information acquisition unit 48 in FIG.

Then, the purchase process evaluation unit 75 estimates the cost when purchasing the insufficient material in the destination store candidate as the cost required for the procurement process “purchase”. The charges for various materials may be general charges, or may be obtained from the website if the charges for various materials in the destination store candidate can be referred to on the website.

In addition, when the ingredients in stock are used to prepare the dish to be evaluated, the cost of the ingredients used from the inventory may be added as the cost of the procurement process “purchase”. In that case, the cost of the material used from the inventory may be the charge at the time of purchase or may be a general charge. Further, the recipe information of the recipe information storage unit 32 of FIG. 2 stores the material costs of various dishes (see FIG. 4), and the cost of the materials for making the dish to be evaluated is stored in the recipe information. It may be the material cost.

Further, when the procurement method to be evaluated is "lunch box", the purchase process evaluation unit 75 requires the procurement process "purchase" from the general charge of the lunch box of the food to be evaluated and the amount of food (the number of lunch boxes). Estimate the cost. If the purchase process evaluation unit 75 can obtain the price of the lunch box and the side dish of the food to be evaluated in the destination store candidate on the website, the purchase process evaluation unit 75 may obtain the price of the lunch box from the website.

In addition, the purchase process evaluation unit 75 estimates the time and effort required for the procurement process “purchase”. For example, assuming that the work of purchasing at the destination store candidate requires more time and effort than when moving to the destination store candidate, the labor coefficient of a larger value than that during the procurement process “move” and the procurement process “ The product of the time required for "purchase" is estimated as the cost required for the procurement process "purchase".

The ordering process evaluation unit 76 includes procurement included in the evaluation target procurement method when the evaluation target procurement method is "fourth home cooking", "sixth home cooking", or "delivery". Evaluate the time, cost, and labor required for the process "ordering".

The procurement process “ordering” represents a process from placing an order to a supplier store candidate set by the supplier store candidate setting unit 73 until the preparation for delivery is completed and the delivery is started.

For example, the ordering process evaluation unit 76 considers the standard time required from ordering to shipping, considering the date (day of the week) when the candidate store to be ordered and the degree of congestion according to the time zone, and considers the procurement process “ Estimate the time required for "ordering". Further, when the estimated time required from ordering to shipping can be referred to on the website in the ordering party candidate, the ordering process evaluation unit 76 uses the estimated time acquired from the website as the time required for the procurement process “ordering”. You may estimate.

In addition, the ordering process evaluation unit 76 determines the type and amount of ingredients for making the food to be evaluated when the procurement method to be evaluated is the "fourth home cooking" and the "sixth home cooking". And, the cost required for the procurement process "ordering" is estimated by referring to the type and quantity of the material (material in stock) stored in the user's home.

When the procurement method to be evaluated is "fourth home cooking" or "sixth home cooking", the cost required for the procurement process "ordering" is that the procurement method to be evaluated is "third". Since it is estimated by the same method as the cost required for the procurement process "purchase" in the case of "home cooking" or "fifth home cooking", the description thereof will be omitted.

Further, when the procuring method of the evaluation target is "delivery", the ordering process evaluation unit 76 requires the procuring process "delivery" from the general charge for delivery of the food to be evaluated and the amount of food (number of orders). Estimate the cost. If the ordering process evaluation unit 76 can acquire the delivery charge of the food to be evaluated in the ordering party store candidate on the website, the ordering process evaluation unit 76 may acquire the delivery charge from the website.

It is assumed that the cost required for the procurement process "ordering" includes the cost required for delivery and delivery, and the cost required for the procurement process "delivery" is 0.

In addition, the ordering process evaluation unit 76 estimates the time and effort required for the procurement process “ordering”. Since the work of the procurement process "ordering" is performed by the supplier store, the time and effort required for the procurement process "ordering" is set to zero.

When the procurement method to be evaluated is "eating out", the order process evaluation unit 77 evaluates the time, cost, and labor required for the procurement process "order" included in the procurement method to be evaluated.

The procurement process “order” represents a process from when the user enters the destination store candidate set by the destination store candidate setting unit 72 to when the food ordered by the user is provided.

For example, the order process evaluation unit 77 considers the congestion condition according to the date and time zone when the destination store candidate is used with respect to the time of the standard procurement process “order” in eating out, and the procurement process “order”. Estimate the time required for. The order process evaluation unit 77 acquires information on the degree of congestion according to the date and time zone in which the destination store candidate is used from the website related to the destination store. It should be noted that the information on the degree of congestion according to the date and time zone in which the destination store candidate is used may be predetermined general information such that the store is crowded in the evening time zone.

Further, the ordering process evaluation unit 77 estimates the cost when the food to be evaluated is ordered in the destination store candidate as the cost required for the procurement process “order”. The ordering process evaluation unit 77 may acquire the price of the food in the destination store candidate from the website, or may use it as the standard price of the food to be evaluated.

In addition, the order process evaluation unit 77 estimates the time and effort required for the procurement process “order”. Since the work of the procurement process "order" is almost performed by the store side, the time and effort required for the procurement process "order" is set to zero.

When the procurement method to be evaluated is "fourth home cooking", "sixth home cooking", or "delivery", the delivery process evaluation unit 78 includes procurement included in the procurement method to be evaluated. Evaluate the time, cost, and effort required for the process "delivery".

The procurement process "delivery" represents a process from the completion of preparation for delivery to the start of delivery in the procurement process "ordering" until the ordered ingredients or dishes arrive at home.

The delivery process evaluation unit 78 acquires the estimated delivery time of the supplier store candidate from the website and estimates the time required for the procurement process “delivery” based on the estimated delivery time. The delivery process evaluation unit 78 may consider the date and time zone of delivery when estimating the time required for the procurement process “delivery”.

In addition, the delivery process evaluation unit 78 estimates the cost and labor required for the procurement process “delivery”. The cost is the shipping fee, and if the ordered material or the delivery fee includes the shipping fee, the cost is set to 0. The time and effort is set to 0 because there is almost no user time and effort related to delivery.

The preparation process evaluation unit 79 is evaluated when the procurement method to be evaluated is "first home cooking", "third home cooking", or "fourth home cooking". Evaluate the time, cost, and labor required for the procurement process "preparation" included in the procurement method.

The procurement process "preparation" represents a process of washing, cutting, kneading, mixing, etc. other than the procurement process "cooking" in which heating is performed in the cooking process of cooking.

The preparatory process evaluation unit 79 estimates the time required for the procuring process “preparation” of the dish to be evaluated with reference to the recipe information of the recipe information storage unit 32 of FIG. In addition, when estimating the time required for the procurement process "preparation", the preparation process evaluation unit 79 is based on the amount of food (the number of people who eat) specified by the user, the skill of the person who cooks the food, and the like. Adjust the length of time required for the procurement process “preparation”. The preparation process evaluation unit 79 and the cooking process evaluation unit 80 may acquire recipe information of the dish to be evaluated from the website. In that case, when the general cooking time of the food to be evaluated is shown as the cooking time, etc., the time required for the procurement process "preparation" is the time obtained by subtracting the heating time from the cooking time. May be good.

Further, the preparation process evaluation unit 79 estimates the cost required for the procurement process “preparation”. Since the preparation is almost manual work, the cost is set to 0.

Further, the preparation process evaluation unit 79 calculates the product of the time required for the procurement process “preparation” and the labor coefficient indicating the amount of labor in the procurement process “preparation” for the procurement process “preparation”. Estimate as. For example, the labor coefficient in the procurement process “preparation” may be predetermined for each dish or may be a constant value.

The cooking process evaluation unit 80 includes a procurement process included in the evaluation target procurement method when the evaluation target procurement method is any one of "first home cooking" and "sixth home cooking". Evaluate the time, cost, and effort required for "cooking".

Procurement process “Cooking” represents the process of heating the raw material or semi-processed product of the dish to be evaluated.

The cooking process evaluation unit 80 estimates the time required for the procurement process “cooking” for the dish to be evaluated with reference to the recipe information of the recipe information storage unit 32 of FIG.

Further, the cooking process evaluation unit 80 determines the time required for the procuring process “cooking” based on the amount of food (the number of people who eat) specified by the user, the skill of the person who cooks the food, and the like. The time required for "cooking" may be adjusted.

In addition, the cooking process evaluation unit 80 estimates the cost required for the procurement process “cooking”. The cost is the usage fee of gas and electricity used for heating. However, gas and electricity charges may not be included as the cost required for the procurement process "cooking".

Further, the cooking process evaluation unit 80 estimates the product of the time required for the procurement process “cooking” and the labor coefficient indicating the amount of labor in the procurement process “cooking” as the labor of the procurement process “cooking”. For example, the labor coefficient in the procurement process “cooking” is predetermined for each dish.

As described above, the procurement process evaluation unit 47 evaluates the time, cost, and labor of each process included in the procurement method of the evaluation target for the food to be evaluated, and the information is transmitted to the meal plan draft preparation unit 49 of FIG. Be supplied.

In FIG. 8, the meal plan drafting unit 49 generates candidates for the meal plan to be presented to the user. For each menu candidate set by the menu candidate setting unit 44, the meal plan draft includes a procurement method for procuring each of the dishes included in the menu candidate, and the time and order of each procurement process included in the procurement method. Represents a draft plan that defines.

The meal plan drafting unit 49 appropriately evaluates each of the menu candidates set by the menu candidate setting unit 44 by the procurement process evaluation unit 47 as a method of procuring each dish included in the menu candidate. One candidate for a meal plan is the case where any of the procurement methods (excluding "eating out") is adopted. Then, the meal plan drafting unit 49 creates as many meal plan candidates (referred to as meal plan candidates) as possible by changing the procurement method adopted for each dish.

For example, suppose that a menu candidate includes cooking M1 and cooking M2, and the procurement methods other than "eating out" evaluated by the procurement process evaluation unit 47 are the procurement method Y1 and the procurement method Y2. In this case, four meal plan candidates W1 to W4 are created for the menu candidate V1.

The meal plan candidate W1 is a plan in which the food M1 is procured by the procurement method Y1 and the food M2 is procured by the procurement method Y1.

The meal plan candidate W2 is a plan in which the food M1 is procured by the procurement method Y1 and the food M2 is procured by the procurement method Y2.

The meal plan candidate W3 is a plan in which the food M1 is procured by the procurement method Y2 and the food M2 is procured by the procurement method Y1.

The meal plan candidate W4 is a plan in which the food M1 is procured by the procurement method Y2 and the food M2 is procured by the procurement method Y2.

In addition, the meal plan drafting unit 49 evaluates "eating out" as a method of procuring each dish included in the menu candidate for each of the menu candidates set by the menu candidate setting unit 44, and the destination store. When the candidates are in the same store, one meal plan candidate is the case where the procuring method of each dish of the menu candidate is "restaurant".

In addition, when the meal plan draft preparation unit 49 prepares the meal plan draft candidate, each time of the procurement process of each dish included in the menu candidate is set as the time estimated by the procurement process evaluation unit 47, and each Arrange the procurement processes in an appropriate order and create a time schedule from the start time of meal preparation.

When creating a time schedule, the meal plan drafting unit 49 can independently perform processes that can be performed in parallel in consideration of, for example, the number of people preparing meals and the number of cooking utensils such as a stove and a microwave oven. Create an efficient time schedule as a process. In addition, the meal plan drafting unit 49 procures by considering the number of people preparing meals and performing the procurement process "movement" and the procurement process "purchase" in parallel with the procurement process "cooking". Avoid time schedules that leave no one to monitor the process “cooking”.

When the meal plan preparation unit 49 creates a time schedule for each of the meal plan candidates, the time, cost, and labor required to procure the menu candidates for each of the meal plan candidates (meal procurement). Time, cost, and effort required for this).

The meal plan drafting unit 49 acquires the time required for procuring each meal of the meal plan candidate from the prepared time schedule. In addition, the meal plan drafting unit 49 adds the cost and labor of each dish procuring process included in the menu candidate for each meal plan candidate, and adds each meal of each meal plan candidate. Calculate the cost and labor required for procurement.

Then, the meal plan drafting unit 49 sets as a meal plan draft that presents only the meal plan draft candidates that meet the conditions set by the presentation condition setting unit 50 among the created meal plan draft candidates to the user.

That is, the presentation condition setting unit 50 sets the menu condition set by the menu condition setting unit 43 and the menu condition (condition set as a valid element by the user) set by the procurement method condition setting unit 45 as the presentation condition. To do.

For example, among the elements of the menu condition shown in FIG. 9, for example, the elements such as “cost” and “cooking time” are clarified in the menu condition in the menu condition setting unit 43 and the menu candidate setting unit 44 in FIG. Only menus that do not conform to are excluded from the menu candidates.

On the other hand, for each of the meal plan candidates, the time, cost, and labor required to procure meals are required, so that the menu conditions set by the menu condition setting unit 43 among the meal plan candidates are not met. Candidates for meal plans are clarified. Regarding the procurement method conditions, as with the menu conditions, among the meal plan candidates, the meal plan candidates that do not match the procurement method conditions set by the procurement method condition setting unit 45 are clarified.

Therefore, the meal plan preparation unit 49 presents only the meal plan candidates that meet the menu conditions and the procurement method conditions set by the presentation condition setting unit 50 to the user among the prepared meal plan candidates. Set as a plan.

In addition, in the menu candidate setting unit 44 and the procurement method candidate setting unit 46, the menu condition and the menu condition and the meal plan draft preparation unit 49 are not limited to the menu candidate conforming to the menu condition and the procurement method candidate conforming to the procurement method condition. It may be limited to a meal plan that meets the procurement method conditions.

Further, the presentation condition setting unit 50 may set a condition that is not included in either the menu condition or the procurement method condition as the presentation condition based on the information from the input information acquisition unit 42. For example, when the user specifies a date and time zone for procuring meals, the presentation condition setting unit 50 sets presentation conditions limited to the meal plan draft for procuring meals on the designated date and time zone. The user specifies, for example, the date and time when the meal preparation is started and the date and time when the meal is procured by designating the date and time when the meal is started.

The meal plan drafting unit 49 selects a meal plan draft that matches the presentation conditions set by the presentation condition setting unit 50 from the meal plan draft candidates, and supplies the presentation order setting unit 51.

The presentation order setting unit 51 sets the presentation order of each meal plan plan according to the presentation order condition set by the presentation order condition setting unit 52 for the meal plan plan from the meal plan plan preparation unit 49. The higher the priority of the meal plan, the higher the presentation order.

The presentation order condition setting unit 52 sets the presentation order condition based on the information specified by the user. For example, when the user specifies the time required for procuring meals as the presentation order condition, the presentation order condition setting unit 52 indicates that the shorter the time required for procuring meals, the higher the priority (higher presentation order) meals. Set the presentation order condition as a draft plan. When the user specifies the cost required for procuring meals as the presentation order condition, the presentation order condition setting unit 52 proposes a meal plan having a higher priority (higher presentation order) as the cost required for procuring meals is lower. Set the presentation order condition.

Further, when there are a plurality of meal plan proposals for the same menu candidate, the presentation order condition setting unit 52 does not own the cooking utensil assumed to be used in the recipe for the dishes included in the menu candidate. Occasionally, the presentation order condition may be set so as to give higher priority to the meal plan of the procurement method of making food from "delivery" or semi-processed products instead of cooking from raw materials.

In addition, when there are a plurality of meal plan proposals for the same menu candidate and there are competing cooking utensils for the dishes included in the menu candidate, the presentation order condition setting unit 52 determines according to the priority of the dishes. The presentation order condition may be set.

For example, if the same cooking utensil is used for a plurality of dishes, the cooking time becomes long. Therefore, the presentation order condition setting unit 52 procures the dishes desired by the user for dishes having no duplication of cooking utensils and having a high priority. Set the presentation order conditions to give higher priority to the proposed meal plan in which the method is adopted.

The high-priority dish is, for example, a dish designated by the user or a dish registered in advance as user information, and is a dish (or a favorite dish) that the user is particular about. The dishes that the user is particular about include the dishes of the restaurant that the user likes and can be delivered, or the dishes that have his own flavor. For the former, the procurement method desired by the user is “delivery”, and for the latter, the procurement method for the user to prepare food from raw materials. Further, the presentation order condition setting unit 52 may set a dish having a particular preference between the user and the person who eats as a dish having a high priority, not limited to the user. Further, the main dish among the dishes included in the menu candidates may be a high-priority dish, and the procurement method of the high-priority dish may be a procurement method in which the user prepares a dish from raw materials.

In the environment grasping system 14 (FIG. 1), a camera installed in a kitchen or the like routinely recognizes a user's cooking state. Then, when the user cooks without referring to the recipe on the Internet, the environment grasping system 14 interprets it as the user's original recipe and grasps it as a (strong) dish with particularity, and uses it as environmental information. It may be transmitted to the information generation server 12.

The presentation page generation unit 53 generates a presentation page for displaying the meal plan draft to be presented to the user on the user's information terminal in the presentation order set in the presentation order setting unit 51. For example, the presentation page generation unit 53 generates a presentation page in which each meal plan is arranged in the order of presentation (in descending order of priority) from the top to the bottom of the presentation page.

The presentation page generation unit 53 transmits the generated presentation page to the user's information terminal via the communication unit 22 and displays it on the information terminal.

The meal plan may be information showing only the menu candidate and the procurement method of each dish included in the menu candidate, or may be information including a time schedule. Further, the meal plan proposed to be displayed on the user's information terminal by the presentation page may be only one meal plan with the highest priority, or a plurality of predetermined meal plans among the high-priority meal plans. It may be a meal plan.

According to the above information generation server 12, the menu and procurement method according to the user's situation and the like are presented based on the information related to the user, so that the user can efficiently prepare meals. Become.

<Specific example>
Next, a specific example of presenting the meal plan plan to the user using the information processing system 11 will be described with reference to the flowchart of FIG. In this specific example, a case where the user specifies a dish (menu) that he / she wants to eat is illustrated.

FIG. 13 is a flowchart illustrating a flow of processing for presenting the meal plan plan to the user.

In step S11, the user determines the desired dish and inputs the type and amount of the desired dish from the information terminal (UI system 13). When inputting a desired dish, the user may be able to select the desired dish from a recipe search site or the like, or may select from a pre-registered menu list.

In step S12, the information generation server 12 reads the information specified by the user. The user here is mainly assumed to be a user who cooks. The user who cooks is assumed to match the user who specified the dish in step S11, but may be explicitly selected. In that case, the user information is read and reflected in the subsequent weighting.

In addition, when the information generation server 12 can recognize a user who only eats, the information generation server 12 also acquires the information of the user. The reason for acquiring information on users who only eat is that the weighting changes depending on the taste of the eater, and if the eater has less time to eat, it should be reflected in the procurement method. is there.

It is assumed that the user selects "takikomi gohan", "fried chicken", "mapo tofu", and "Caesar salad" around noon, and inputs the amount of each.

<Example of menu and quantity specified by the user>
FIG. 14 is a diagram illustrating the menu (type of food) and the amount specified by the user.

FIG. 14 shows that the user has designated "takikomi gohan" for 4 servings, "fried chicken" for 2 servings, "mapo tofu" for 4 servings, and "Caesar salad" for 3 servings.

Suppose that the user wants to start eating rice after 70 minutes, and only one user cooks and the stove cannot work in parallel with one bite.

In step S13 of FIG. 13, the information generation server 12 selects a selectable procurement method.

First, narrow down what is available in the delivery service by the user's home address and time zone. For example, by inputting an address and a time zone into the Web service of each delivery service, information is automatically collected and the situation is grasped.

<Example of collection result of information on availability of delivery service>
FIG. 15 is a diagram showing the result of collecting information on the availability of the delivery service.

The first column at the left end shows the type of service, the second column shows the service name, and the third column shows the result of availability. The service with the service name "A" has a service type of food delivery and is available. The service with the service name "C" has a service type of delivery, and the result shows that it can be used. The result is that none of the services with the service names "B", "D", and "E" can be used.

As a result, the available delivery services are determined to be food delivery "A" and delivery "C".

The information generation server 12 also grasps the business status of the nearest supermarket or the like. Suppose the nearest supermarket called "F" is open.

Next, check whether the menu selected by the user can be made from the inventory at home. At that time, it is judged whether or not cooking is possible by comparing the database that records the inventory of refrigerators and pantry with the ingredient list of recipe information. For example, if the stock of the refrigerator or pantry is carrots, fried tofu, mushrooms, minced meat, lettuce, and seasonings, the menu can be cooked as shown in FIG.

<Example of whether or not cooking is possible in stock>
FIG. 16 is a diagram illustrating whether or not cooking in inventory is possible.

According to FIG. 16, of the dishes “takikomi gohan”, “fried chicken”, “mapo tofu”, and “Caesar salad” included in the menu desired by the user, only “takikomi gohan” is in stock and cooked. The result is that it is possible.

Therefore, the information generation server 12 proposes to cook "takikomi gohan" at home.

Next, in step S14 of FIG. 13, the information generation server 12 calculates the required time and cost of the procurement method selected in step S13.

<Example of procurement process>
FIG. 17 is a diagram illustrating a procurement process of “takikomi gohan”.

According to FIG. 17, of the 70 minutes of cooking time, 30 minutes is preparation (preparation) and 40 minutes is rice cooking. In this case, another work can be done during the rice cooking time. The gray part indicates that the user is working.

Next, the information generation server 12 examines the examination of the procurement method of "fried chicken", "mapo tofu", and "Caesar salad".

Currently, as an option of procurement method, there is a case of going to a supermarket "F" to purchase, or a case of ordering and delivering to a food delivery "A" or a delivery service "C".

<Examples of selectable procurement methods and procurement times>
FIG. 18 is a diagram illustrating the procurement methods and procurement times that can be selected for “fried chicken”, “mapo tofu”, and “Caesar salad”.

In FIG. 18, in the case of purchasing to the supermarket “F”, the sum of the travel time and the cooking time is the procurement time. When ordering delivery to food delivery "A", the sum of delivery time and cooking time is the procurement time. When ordering delivery to delivery "C", the delivery time is the procurement time.

It takes 10 minutes to move to Super "F" one way. For food delivery, the delivery time is 30 minutes and the delivery time is 45 minutes.

On the other hand, as shown in FIG. 16, the cooking time of "fried chicken" is 30 minutes. "Mapo tofu" uses retort sauce for food delivery, and the cooking time is shortened from 30 minutes to 20 minutes. "Caesar salad" has a cooking time of 10 minutes.

Therefore, as shown in FIG. 18, the procurement time for "fried chicken" is 50 minutes for purchase to the supermarket "F", 60 minutes for ordering and delivering to food delivery "A", and delivery "C". It takes 45 minutes to place an order and have it delivered.

The procurement time for "Mapo tofu" is 40 minutes for purchases to the supermarket "F", 50 minutes for ordering and delivering to food delivery "A", and ordering and delivering to delivery "C". It takes 45 minutes to get it.

The procurement time for "Caesar salad" is 30 minutes for purchases to the supermarket "F", 35 minutes for ordering and delivering to food delivery "A", and delivery "C" cannot be used because it is not handled. ..

If there is a condition that the user wants to start eating within 80 minutes from the menu decision, the purchase to the supermarket "F" is excluded from the options because the purchase of the supermarket and the cooking of "takikomi gohan" are incompatible when leaving the house. The menu. As a result, the procurement method of "Caesar salad" is limited to one, and the procurement method of ordering and delivering to food delivery "A" is determined.

<Example of procurement process when procurement method is finalized>
FIG. 19 is a diagram illustrating a procurement process at a stage when the procurement methods for “takikomi gohan” and “Caesar salad” are determined.

In FIG. 19, the gray part is the state in which the user is working, and the user is occupied with the preparation (preparation) of the “takikomi gohan” for up to 30 minutes. Therefore, the cooking process of "Caesar salad" is a time zone between 40 minutes and 45 minutes, and the user occupies the time zone.

Next, we will consider how to procure "fried chicken" and "mapo tofu".

If food delivery "A" is selected as the procurement method for both "fried chicken" and "mapo tofu", there is not enough time to cook. Therefore, the selection is made based on the cost.

<Examples of selectable procurement methods, procurement time, and unit price>
FIG. 20 is a diagram illustrating the procurement method, procurement time, and unit price that can be selected for “fried chicken” and “mapo tofu”.

In FIG. 20, the numerical value with @ shown in parentheses in each column is the charge for one person. In the food delivery "A", the unit price of "fried chicken" is 300 yen, and the unit price of "mapo tofu" is 200 yen. In the delivery "C", the unit price of "fried chicken" is 800 yen, and the unit price of "mapo tofu" is 600 yen.

Therefore, in the food delivery "A", the charge for "fried chicken" for two people is 300 x 2 = 600 yen, and the charge for "mapo tofu" for four people is 200 x 4 = 800 yen.

In the delivery "C", the charge for "fried chicken" for 2 people is 800 x 2 = 1600 yen, and the charge for "mapo tofu" for 4 people is 600 x 4 = 2400 yen.

Excluding the fact that it is not enough time to procure both "fried chicken" and "mapo tofu" by food delivery "A", as condition 1, "fried chicken" is procured by food delivery "A". The charge for procuring "Mapo tofu" at the delivery "C" is 600 + 2400 = 3000 yen.

As condition 2, when "fried chicken" is procured by delivery "C" and "mapo tofu" is procured by food delivery "A", the charge is 1600 + 800 = 2400 yen.

As condition 3, when "fried chicken" is procured by delivery "C" and "mapo tofu" is procured by delivery "C", the charge is 1600 + 2400 = 4000 yen.

Therefore, the case of condition 2 has the lowest cost, and condition 2 is selected.

Next, in step S15 of FIG. 13, the time required for the procurement method is adjusted according to the situation of the user.

<Example of finalized procurement process>
FIG. 21 is a diagram illustrating a procurement process finally determined after all the procurement methods of “takikomi gohan”, “fried chicken”, “mapo tofu”, and “Caesar salad” have been determined.

As shown in FIG. 21, "Mapo tofu" arrives in 30 minutes by food delivery "A". Since the user can appropriately cook "Mapo tofu" during the time after cooking "Caesar salad", for example, the elapsed time is 50 minutes after the completion of "Takikomi gohan". Hit it.

"Karaage" is ordered from delivery "C" so that the delivery process is 25 to 70 minutes in order to match the completion of "Takikomi gohan".

Next, in step S16 of FIG. 13, the information generation server 12 presents the information to the user.

The information generation server 12 presents the result of performing the above processing to the user as a meal plan plan.

<Example of meal plan>
FIG. 22 is a diagram illustrating a meal plan draft notified to the user.

In FIG. 22, the type and amount of dishes desired and specified by the user are shown, and the procurement method of each dish is shown.

The user confirms the contents of the meal plan and places an order for, for example, a food delivery service. Regarding the contents of food delivery, check the inventory status at home and order the minimum amount of ingredients. The information generation server 12 may place an order for a food delivery service or the like.

As described above, since the menu procurement method according to the user's situation and the like is presented, the user can efficiently prepare meals.
