Abstract: To perform appropriate seat assignment in accordance with a reservation reception state in an information processing device that receives a reservation. A storage unit stores information on a first table group which is ordered and a second table group which is used in a case where there is no room for the first table group. The control unit associates received reservation information with tables of the first table group in order from a higher-order table on the basis of the reservation information, when the reservation information is received. In a case where the first table group does not include a table associated with the reservation information, the control unit cancels the association of a plurality of pieces of existing reservation information, and calculates a degree of priority on the basis of the reservation information.

Abstract: [Problem] To provide a work management method, a work management program, and a work management apparatus that can reduce the time and effort of the staff of a facility. [Solution to problem] A work management apparatus 2 according to the present invention includes: a reservation processing unit 211 configured to manage reservation information that indicates reservations made for a facility; and a notification processing unit 212 configured to notify, based on the reservation information, staff of the facility of a job that is to be done by the staff, at a predetermined notification timing that has been set in advance in correspondence with the job.

Abstract: There are provided an authentication processing system and an authentication processing server for authenticating a screen when using various facilities, such as restaurants. The authentication processing system includes a portable communication terminal and an authentication processing server. The authentication processing server includes: a code table generation processing unit that generates a code table including a plurality of first codes and a second code, which is associated with each of the plurality of first codes for each time period; a code table storage unit that stores the code table generated by the code table generation processing unit; a clock processing unit having a clock function; and a user processing unit that receives a first code from a portable communication terminal, specifies a second code corresponding to the first code from the code table based on date and time information in the clock processing unit, and transmits the specified second code to the portable communication terminal.

Abstract: An object providing a route determination system that determines a railroad route used by a user, without using a system of a railroad company, includes a distance calculation processing unit, a route identification processing unit, a speed calculation processing unit, and a route determination processing unit. The distance calculation processing unit calculates a distance from each of a plurality of pieces of positional information acquired by a mobile communication terminal that is used by a user. The route identification processing unit identifies a closest route on the basis of the calculated distances. The speed calculation processing unit identifies the pieces of positional information of which the distance to the identified route is shorter than or equal to a predetermined threshold, and calculates a moving speed between positions in the identified route to which the identified pieces of positional information correspond.
