Description

  The present invention relates to an information processing apparatus, an information processing method, and a program capable of executing processing related to reservation of a service facility such as a restaurant or an accommodation facility.

  Conventionally, there is a system that can accept a provisional reservation of a restaurant (a reservation that is canceled or discarded under a predetermined condition). In the following Patent Document 1, when a reservation is made for an accommodation facility or a restaurant, if the user applies for a reservation from a place other than the designated position, the reservation is accepted as a provisional reservation, for example, from the designated position within 24 hours. It is disclosed that a temporary reservation is discarded if there is no reservation telephone.

JP 2014-006642 A

  However, with this technology, even if the user who made a temporary reservation is highly interested in the restaurant, the temporary reservation is discarded after 24 hours uniformly, so if the temporary reservation disappears or the temporary reservation is made When the user actually uses the restaurant, the influence on the restaurant is not considered.

  In view of the circumstances as described above, the object of the present invention is to allow a user who is considering a reservation for a service facility to accept a temporary reservation while the temporary reservation is lost or the user who has made the temporary reservation An object of the present invention is to provide an information processing apparatus, an information processing method, and a program capable of flexibly changing a provisional reservation acceptance mode according to the influence on a restaurant when the restaurant is actually used.

  In order to achieve the above object, an information processing apparatus according to an aspect of the present invention includes a storage unit, a communication unit, and a control unit. The storage means stores facility information regarding a plurality of service facilities. The communication means can communicate with a facility terminal and a plurality of user terminals of each service facility. The control means receives a provisional reservation request that is a time-limited reservation for any service facility from the user terminal to which the facility information is provided, and includes at least the number of reservations included in the received provisional reservation request and In accordance with the information indicating the customer unit price, the temporary reservation state maintenance period is set. Further, the control means transmits a provisional reservation maintenance notice requesting maintenance of the provisional reservation state based on the provisional reservation request to the facility terminal of the service facility for the set maintenance period, and the provisional reservation request A maintenance period notification for notifying the set maintenance period is transmitted to the user terminal of the transmission source.

  With this configuration, the information processing apparatus allows a user to make a temporary reservation for a limited time, and changes the maintenance period according to the number of temporary reservations and / or the unit price of customers, thereby making a provisional reservation with a large number of people or a high unit price of customers. Temporary reservations such as prompting reservation confirmation earlier to avoid risk, conversely provisional reservation with a large number of people or unit price per customer, expecting to increase sales at the time of reservation confirmation by waiting for the reservation confirmation for a long time, etc. It is possible to flexibly change the provisional reservation reception mode in consideration of the disappearance of the reservation or the influence of the final reservation.

  The control means may set the maintenance period to be shorter as the number of reserved people and / or the unit price of customers increases.

  As a result, the information processing device has a large adverse effect when a temporary reservation with a large number of people or a high unit price per customer and it does not reach the actual reservation. To avoid the above risks.

  The control means may set the maintenance period longer as the number of reserved people and / or the unit price of customers increases.

  As a result, the information processing device can expect temporary sales with a large number of people or a high unit price per customer, and large sales can be expected. By setting a longer maintenance period, the information processing device gives the user more time to review the reservation, The probability of booking confirmation can be increased.

  The storage means stores reservation history information including at least past provisional reservations and main reservations and cancellations, the number of times of use, and the use frequency by the user of the user terminal that has transmitted the provisional reservation request. Also good. In this case, the control means may shorten or extend the set maintenance period according to the reservation history information.

  As a result, the information processing apparatus sets the maintenance period in consideration of historical information such as the final reservation confirmation rate, the number of times of use, and the frequency of use based on the past temporary reservation of the user of the temporary reservation request source. The risk of not making a reservation can be avoided, and the possibility of reaching this reservation can be increased.

A program according to another aspect of the present invention is:
Stores facility information about multiple service facilities,
Receive a provisional reservation request that is a timed reservation for any of the service facilities from the user terminal that provides the facility information,
According to the information indicating at least the number of reservations and / or the unit price of customers included in the received provisional reservation request, the maintenance period of the provisional reservation state is set,
Sending a provisional reservation maintenance notification requesting maintenance of the provisional reservation state based on the provisional reservation request to the facility terminal of the service facility for the set maintenance period;
Transmitting a maintenance period notification for notifying the set maintenance period to the user terminal that has transmitted the provisional reservation request.

A program according to another embodiment of the present invention is provided in an information processing device.
Storing facility information relating to a plurality of service facilities;
Receiving a provisional reservation request that is a timed reservation for any service facility from the user terminal of the facility information providing destination;

  In particular, in the present embodiment, the storage unit 18 stores information related to the main reservation request and the temporary reservation request received from the user terminal 200, and the restaurant information providing server 100 uses these data to make a reservation / temporary reservation. An application and other programs for executing processing and maintenance period setting processing are stored. As will be described later, the storage unit 18 includes a restaurant information database, a user information database, a main reservation / temporary reservation information database, and a number / unit price / maintenance period correspondence information database as databases including such data. .

  The communication unit 19 is a wireless communication module such as an Ethernet NIC (Network Interface Card) or a wireless LAN, and is responsible for communication processing with the user terminal 200.

  Although not shown, the basic hardware configuration of the user terminal 200 and the restaurant terminal 300 is substantially the same as the hardware configuration of the restaurant information providing server 100.

[Database configuration of restaurant information server]
FIG. 3 is a diagram showing a configuration of a database included in the restaurant information providing server 100.

  As shown in the figure, the restaurant information providing server 100 stores a restaurant information database 31, a user information database 32, a main reservation / temporary reservation information database 33, and a number / unit price / maintenance period correspondence information database 34 in the storage unit 18. have.

  The restaurant information database 31 includes, for each restaurant, the store name and location information of the restaurant, the ID (store ID) for identifying the restaurant, the category information of the restaurant business type and service, and the restaurant. , That is, information indicating the characteristics of the store, such as PR statements of the store, event information performed by the restaurant, area information where the restaurant is located, restaurant address, telephone number, restaurant ( Stores image data (introducing stores), menu information about menus provided by restaurants, business hours, website URLs, and the like.

  The menu information is information corresponding to a menu posted on each restaurant site on the portal site, and stores menu names of a plurality of menus that each restaurant can provide for each restaurant. . The menu information may be stored for each menu category such as appetizer / main and lunch / dinner / course. If the image data corresponds to a menu, the image data is stored in association with the menu information.

  The area information is, for example, in units of prefectures, but information may be stored in units of a narrower range such as municipalities. The category information may include, for example, main categories such as Japanese food, Chinese, Italian, French, and yakiniku, and more detailed subcategories such as yakitori and tempura in Japanese food, pasta and pizza in Italian, and the like.

  The user information database 32 stores information about a user who owns the user terminal 200 and is a user (member) of a restaurant information service through the portal site provided by the restaurant information providing server 100. Specifically, the user information database 32 stores information such as a user ID, a password, a name, an e-mail address, a telephone number, an address, an age (layer), a gender, a birthday, and past book / temporary reservation history information. Remember every time.

  The main reservation / temporary reservation information database 33 includes reservation information (for example, restaurant name, reservation time) received from the user terminal 200 and included in the main reservation request and temporary reservation request of each restaurant whose reservation date has not yet arrived. , Reservation number of people, reservation course, customer unit price, etc.) are stored in association with user information for identifying the user of the user terminal 200.

  Further, the main reservation / provisional reservation information database 33 stores maintenance period information indicating the maintenance period for each provisional reservation. The maintenance period is set according to the number of reservations and / or the customer unit price of the provisional reservation based on the information stored in the number / unit price / maintenance period correspondence information database 34.

  The number / unit price / maintenance period correspondence information database 34 is a database that is referred to when setting the maintenance period of the provisional reservation, and stores information indicating each maintenance period corresponding to the number of persons or the customer unit price of the provisional reservation. The For example, the maintenance period is set to be shorter as the number of reservations or the customer unit price increases. More specifically, the maintenance period is 5 days for temporary reservations of 1-2 people (or 3,000 yen per customer) and 3 days for temporary reservations of 3 to 4 people (or 5,000 yen per customer). A reservation for a reservation of 5 or more people (or a customer unit price of 7,000 yen or more) is set as one day, but is not limited thereto.

  Each of these databases is used by referring to each other as necessary in the restaurant reservation process by the restaurant information providing server 100 described later.

[Operation of restaurant information provision server]
Next, operation | movement of the restaurant information provision server 100 comprised as mentioned above is demonstrated. The operation is executed in cooperation with the hardware such as the CPU 11 and the communication unit 19 of the restaurant information providing server 100 and the software stored in the storage unit 18. In the following description, for the sake of convenience, the CPU 11 is an operation subject.

  FIG. 4 is a flowchart showing a restaurant reservation process performed by the restaurant information providing server 100. Below, especially the provisional reservation of a restaurant and this reservation process based on it are demonstrated.

  As shown in the figure, the CPU 11 of the restaurant information providing server 100 first receives a provisional reservation request for a certain restaurant from the user terminal 100 via the restaurant information list on the portal site. Is determined (step 41). Although not shown, here, in the restaurant information list, a user interface for requesting a temporary reservation is provided separately from a user interface (for example, a reservation button) for requesting a main reservation (for example, a temporary reservation button). Suppose that is provided.

  If it is determined that the provisional reservation request has been received (Yes), the CPU 11 uses the reservation information (for example, restaurant name, reservation time, number of reservations, use course, customer unit price, etc.) included in the provisional reservation request as the user. The information is stored in association with user information such as the user ID of the terminal 200 (step 42).

  Subsequently, the CPU 11 refers to the number / unit price / maintenance period correspondence information database 34 according to the information indicating the number of reservations and / or the unit price of customers included in the reservation information of the provisional reservation request, and maintains the provisional reservation maintenance period. Is set (step 43).

  Subsequently, the CPU 11 transmits a provisional reservation maintenance notification requesting maintenance of the provisional reservation state for the set maintenance period to the restaurant terminal 300 of the restaurant (step 44).

  Further, the CPU 11 transmits a maintenance period notification for notifying the set maintenance period to the user terminal 200 that has transmitted the provisional reservation request (step 45).

  Subsequently, the CPU 11 determines whether or not the end time of the set temporary reservation maintenance period has come (step 46).

  When it is determined that the end time of the temporary reservation maintenance period has arrived (Yes), the CPU 11 records the temporary reservation cancellation in the main reservation / provisional reservation information database 33 and cancels the temporary reservation to the user terminal 200 and the restaurant terminal 300. A notification is transmitted (step 47). The temporary reservation cancellation history can be stored in the user information database 32 as a part of the user's actual reservation / temporary reservation history.

  On the other hand, if it is determined in step 49 that the end time of the provisional reservation maintenance period has not arrived (No), the CPU 11 determines whether or not the main reservation request has been received from the user terminal 200 that has transmitted the provisional reservation request. Judgment is made (step 48).

  When it is determined that the main reservation request is received from the user terminal 200 (Yes), the CPU 11 transmits the main reservation request by the user of the temporary reservation request source to the restaurant terminal 300 of the temporary reservation destination restaurant (step) 49) The reservation completion notice is transmitted to the user terminal 200 of the user (step 50).

  On the other hand, if it is determined in step 48 that the main reservation request has not been received from the user terminal 200 (No), the CPU 11 returns to step 44 and repeats the subsequent processing.

[Summary]
As described above, according to the present embodiment, the restaurant information providing server 100 changes the maintenance period according to the number of temporary reservations and / or the customer unit price while allowing a user to make a temporary reservation. Therefore, it is possible to flexibly accept provisional reservations in consideration of the effects of the disappearance of the provisional reservation or the finalization of the reservation, such as avoiding the risk by promptly confirming the reservation and avoiding the risk, such as a provisional reservation with a large number of people or a high unit price per customer. Can be changed.

  In addition, once the user of the user terminal 200 transmits a provisional reservation request to the restaurant information providing server 100, the user terminal 200 receives the notification of the maintenance period so that the user can grasp how long the reservation needs to be established. The traffic between the user terminal 200 and the restaurant information providing server 100 while allowing the provisional reservation request is not required because the restaurant information providing server 100 need not be accessed many times to confirm the reservation status. Can be kept to a minimum, and the load on the restaurant information providing server 100 can be prevented from becoming too large.

[Modification]
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present disclosure.

  In the above-described embodiment, the provisional reservation maintenance period is set to be shorter as the number of reservations or the customer unit price increases. However, conversely, the maintenance period may be set to become longer as the number of reservations or the customer unit price increases. As a result, provisional reservations with a large number of people or a high unit price per customer can be expected to generate large sales. By setting a longer maintenance period, the user is given more time to review the reservation, and the probability of the reservation being confirmed. Can be increased.

  In addition, the maintenance period may be set based on both the number of reserved reservations and the unit price of customers, that is, based on an amount obtained by multiplying the unit price of customers by the number of reservations. In this case, the maintenance period may be set shorter as the amount of money multiplied is larger, or the maintenance period may be set longer as the amount of money multiplied is larger.

  In the above-described embodiment, in the number / unit price / maintenance period correspondence information database 34, fixed maintenance period information corresponding to the number of reserved reservations and / or the unit price of the customer is stored, and the maintenance period is set based on the information. It was. However, a plurality of types of such databases may exist depending on conditions such as the season, month, week, day of the week, etc., and different maintenance periods may be set according to the conditions of the provisional reservation date.

  In the above-described embodiment, the temporary reservation maintenance period is set according to the number of reservations and / or the customer unit price of the temporary reservation. The maintenance period depends on the past reservation history information of the user of the temporary reservation request source. May be extended or shortened. The reservation history information includes, for example, any of past temporary reservations and actual reservations as well as cancellations, usage times, and usage frequencies by the user of the temporary reservation request source. In this case, the restaurant information providing server 100 refers to the user's reservation (main reservation / provisional reservation) history information (including the main reservation / provisional reservation cancellation information) stored in the user information database 32, and The above-mentioned reservation reservation rate based on past provisional reservations (the above-mentioned reservation reservation rate based on past provisional reservations is the ratio of the number of book reservations based on provisional reservations to the total number of past book reservations) The maintenance period may be shortened or extended.

  Specifically, the restaurant information providing server 100 extends the maintenance period by a predetermined time when the final reservation confirmation rate based on the past temporary reservation is higher than a predetermined first threshold, When the reservation reservation rate based on the reservation is lower than a predetermined second threshold (lower than the first threshold), the maintenance period may be shortened by a predetermined time. Alternatively, a predetermined reference value (for example, 50%) is set for the final reservation fixed rate based on the past provisional reservation, and a predetermined extension period is set for each of a plurality of numerical values for the fixed rate equal to or higher than the reference value. A predetermined shortening period may be set for each of a plurality of numerical steps with respect to a fixed rate equal to or less than the value. Further, the restaurant information providing server 100, when the user of the provisional reservation requesting source has used the provisional reservation target restaurant so far, the number of times of use, or the reservation cancellation rate is equal to or greater than a predetermined threshold value for each. The maintenance period may be extended, and the maintenance period may be shortened if it is less than a predetermined threshold.

  Thereby, the restaurant information providing server 100 extends the maintenance period when the user who has transmitted the provisional reservation request has a high past use record (ie, high reliability), and shortens the maintenance period in the opposite case. Thus, it is possible to give higher priority to a user who is more likely to confirm the main reservation and to determine the main reservation as a whole.

  In the above-described embodiment, the provisional reservation is treated in the same manner as the main reservation except that the maintenance period is set. However, the provisional reservation may be canceled from the restaurant side before the maintenance period elapses based on a predetermined condition. For example, if a restaurant cancels a provisional reservation before the maintenance period has passed, some penalty may be imposed on the restaurant (for example, the provisional reservation cannot be accepted for a certain period of time), or the provisional reservation requester It may be possible to cancel only when confirmation is obtained from the user.

  In the above-described embodiment, a restaurant is taken as an example of a service facility, but the service facility is not limited to a restaurant, for example, accommodation facilities such as hotels and inns, various sports facilities such as tennis, basketball, and golf, karaoke The present invention can be similarly applied to various service facilities such as amusement facilities such as bowling and treatment facilities such as massage / esthetic treatments.

  Among the inventions described in the claims of the present application, the invention described as “information processing method” is such that each step is automatically performed by at least one device such as a computer by information processing by software. Yes, it is not performed by humans using devices such as computers. That is, the “information processing method” is an information processing method using computer software, and is not a method in which a human operates a computing tool called a computer.
