  (Step S304) The processing unit 13 performs processing corresponding to the instruction. The process returns to step S301. The process corresponding to the instruction is, for example, a calculation process of a burden amount.

  (Step S <b> 305) The receiving unit 12 determines whether information has been received from the terminal device 2. If an instruction is received, the process goes to step S306, and if no instruction is received, the process goes to step S307.

  (Step S306) The processing unit 13 or the like processes the received information. Such processing is called reception information processing. Reception information processing will be described with reference to the flowchart of FIG. The process returns to step S301.

  (Step S307) The processing unit 13 or the like performs other processing. The other process is usually a process performed based on internal information (trigger). Such processing is called other processing. Other processing will be described with reference to the flowchart of FIG. The process returns to step S301.

  In the flowchart of FIG. 3, the process ends when the power is turned off or the process is terminated.

  Next, the reception information processing in step S306 will be described using the flowchart of FIG.

  (Step S401) The evaluation information receiving unit 121 that constitutes the receiving unit 12 determines whether or not the evaluation information has been received. If the evaluation information is received, the process goes to step S402. If the evaluation information is not received, the process goes to step S409.

  (Step S402) The product determining unit 131 temporarily accumulates evaluation information in the storage unit 11 in association with the purchaser identifier.

  (Step S <b> 403) The product determination unit 131 obtains one or more purchaser identifiers corresponding to the evaluation information temporarily stored in the storage unit 11 and the joint purchaser information stored in the joint purchaser information storage unit 112. It is used to determine whether or not the evaluation information of all the joint purchasers has been prepared. If all the evaluation information is available, the process goes to step S404. If all the evaluation information is not available, the process returns to the upper level process. For example, when all of the two or more purchaser identifiers included in the joint purchaser information correspond to the evaluation information temporarily stored in the storage unit 11, the product determination unit 131 evaluates all the joint purchaser evaluation information. It is judged that Moreover, when the predetermined time limit has passed, the product determination unit 131 may determine that the evaluation information of all the joint purchasers has been prepared. The predetermined time limit is, for example, transmitted from the representative terminal device 2 and stored in the storage unit 11.

  (Step S <b> 404) The product determination unit 131 reads two or more pieces of evaluation information temporarily stored in the storage unit 11. Note that the evaluation information includes two or more product identifiers and an evaluation.

  (Step S405) The product determination unit 131 calculates the evaluation of all of the two or more products from the evaluations included in the two or more evaluation information (evaluation information of two or more joint purchasers). For example, the product determination unit 131 acquires the sum or average of two or more evaluations for each product, and sets it as the evaluation of all members.

  (Step S406) The product determination unit 131 acquires the product information of the product with the highest evaluation among the evaluations of each product calculated in Step S405 from the candidate product information storage unit 115 and accumulates it in the purchased product information storage unit 116. .

  (Step S407) The burden amount determination unit 133 determines the burden amount for each of the two or more joint purchasers. The process for determining the amount of burden will be described with reference to the flowchart of FIG.

  (Step S408) The burden amount transmitting unit 142 transmits the burden amounts of the two or more joint purchasers determined in Step S407 to the two or more joint purchasers. The burden amount transmitting unit 142 acquires notification destination information of two or more joint purchasers from the joint purchaser information storage unit 112, and transmits the burden amount to the terminal devices 2 of the two or more joint purchasers. . Return to upper process.

  (Step S409) The payment information receiving unit 123 constituting the receiving unit 12 determines whether or not payment information has been received. If payment information is received, the process goes to step S410, and if payment information is not received, the process goes to step S417. In this step, the purchaser identifier is also usually received.

  (Step S410) The payment information storage unit 134 stores the payment information received in step S409 in the payment information storage unit 118. The payment information is stored in association with the purchaser identifier.

  (Step S411) The payment processing unit 137 uses the payment information stored in the payment information storage unit 118 to determine whether the payment information of all the joint purchasers has been prepared. If it is determined that all the payment information is complete, the process goes to step S412. If it is determined that all the payment information is not complete, the process goes to step S415. Note that the settlement processing unit 137 acquires a purchaser identifier corresponding to each settlement information stored in the settlement information storage unit 118. Further, the settlement processing unit 137 acquires all purchaser identifiers included in the joint purchaser information. Then, the settlement processing unit 137 determines that the settlement information of all the members has been collected when all the settlement information corresponding to each purchaser identifier included in the joint purchaser information is stored in the settlement information storage unit 118. .

  (Step S <b> 412) The payment processing unit 137 performs payment processing using two or more payment information stored in the payment information storage unit 118.

  (Step S413) The payment information deletion unit 138 deletes two or more payment information accumulated in the payment information storage unit 118.

  (Step S414) The shipping processing unit 139 performs a shipping process. Return to upper process.

  (Step S415) The determination unit 135 determines whether or not the payment information received in step S409 is the payment information of the representative of joint purchase. If it is the payment information of the representative, the process goes to step S416, and if it is not the payment information of the representative, the process returns to the upper process. Note that the determination unit 135 acquires the purchaser identifier corresponding to the payment information received in step S409, acquires the purchaser identifier of the representative from the representative information storage unit 113, and the two purchaser identifiers match. In this case, it is determined that the payment information is representative.

  (Step S416) The payment process incomplete person information acquisition unit 136 acquires information on an incomplete person in the payment process. Then, a message for prompting payment processing is transmitted to the terminal device 2 of the person who has not completed payment processing (joint purchaser excluding the representative). Note that the payment processing incomplete person information acquisition unit 136 acquires the payment amount of each payment processing incomplete person from the storage unit 11. Then, the payment processing incomplete person information acquisition unit 136 transmits a prompt message including the burden amount. Note that the information on the incomplete person of the payment processing includes one or more incomplete person notification destination information. Return to upper process.

  (Step S417) The desired amount receiving unit 122 constituting the receiving unit 12 determines whether or not the desired amount has been received. If the desired amount information is received, the process goes to step S418, and if the desired amount is not received, the process goes to step S419.

  (Step S418) The processing unit 13 accumulates the desired amount received in step S417 in the joint purchaser information storage unit 112. The desired amount is stored in association with the purchaser identifier. Return to upper process.

  (Step S419) The processing unit 13 performs other information processing. Return to upper process. For example, the other information processing is the following processing. For example, when the receiving unit 12 receives joint purchaser information, the processing unit 13 accumulates the joint purchaser information in the joint purchaser information storage unit 112. For example, when the receiving unit 12 receives representative information, the processing unit 13 accumulates the representative information in the representative information storage unit 113. For example, when a sharing rule identifier or a sharing rule for identifying a sharing rule adopted by the receiving unit 12 is received, the processing unit 13 accumulates the sharing rule identifier or the sharing rule in the sharing rule storage unit 111. When the sharing rule identifier is accumulated here, the sharing rule used in calculating the burden amount is a sharing rule identified by the sharing rule identifier. For example, when the receiving unit 12 receives the shipping destination information, the processing unit 13 accumulates the shipping destination information in the shipping destination information storage unit 114. For example, when the receiving unit 12 receives one or more candidate product information, the processing unit 13 accumulates the one or more candidate product information in the candidate product information storage unit 115.

  Next, the burden amount determination process in step S407 will be described using the flowchart of FIG.

  (Step S501) The burden amount determination unit 133 reads the amount (M) of the amount storage unit 117. The amount (M) is the amount of the product to be purchased jointly.

  (Step S502) The burden amount determination unit 133 reads the sharing rule to be applied from the sharing rule storage unit 111.

  (Step S <b> 503) The burden amount determination unit 133 determines whether or not the sharing rule to be applied is “split payment”. If it is “split”, go to step S504, and if it is not “split”, go to step S512.

  (Step S504) The burden amount determination unit 133 acquires the number (N) of joint purchasers. In addition, for example, the burden amount determination unit 133 acquires the number of people (N) by acquiring the number of joint purchaser information in the joint purchaser information storage unit 112 or the number of joint purchasers included in the joint purchaser information. To get.

  (Step S505) The burden amount determination unit 133 calculates the burden amount “M / N” per person.

  (Step S506) The burden amount determination unit 133 determines whether or not the joint purchaser information associated with the desired amount exists in the joint purchaser information storage unit 112. If the joint purchaser information associated with the desired amount exists, the process goes to step S507, and if not, the process goes to step S511.

  (Step S507) The burden amount determination unit 133, from the joint purchaser information storage unit 112, among the desired amounts associated with each joint purchaser information, a desired amount less than the burden amount “amount / N” per person. It is determined whether or not exists. If it exists, go to step S508, otherwise go to step S511.

  (Step S508) The burden amount determination unit 133 determines the burden amount of each one or more joint purchasers corresponding to the joint purchaser information associated with the desired amount less than the burden amount per person, as desired by each joint purchaser. Set to amount.

  (Step S509) The burden amount determination unit 133 substitutes “N—the number of people whose burden amount is set in step S508” into the number of people N. Note that the number N is a variable.

  (Step S510) The burden amount determination unit 133 substitutes “M—total burden amount set in step S508” for the amount M. The process returns to step S505. The amount M is a variable.

  (Step S511) The burden amount determination unit 133 sets the burden amount of the joint purchaser for which the burden amount has not been set. Note that the setting of the burden amount is usually to store the burden amount in the joint purchaser information storage unit 112 in association with the purchaser identifier included in the joint purchaser information.

  (Step S512) The burden amount determination unit 133 determines whether or not the sharing rule to be applied is “a rule that varies depending on the attribute”. If it is “a rule that varies depending on the attribute”, the procedure goes to step S513, and if it is not a “rule that varies depending on the attribute”, the procedure proceeds to step S514.

  (Step S513) The burden amount determination unit 133 applies the “rule varying according to the attribute”, determines the burden amount of each joint purchaser, and returns to the higher-level processing. Such processing is called attribute value variation method processing. The attribute value variation method process will be described with reference to the flowchart of FIG.

  (Step S514) The burden amount determination unit 133 substitutes 1 for the counter i.

  (Step S515) The burden amount determination unit 133 determines whether there is an i-th joint purchaser. When the i-th joint purchaser exists, the process goes to step S516, and when it does not exist, the process returns to the upper process. In step S515, the amount input by each joint purchaser is used as the burden amount. The amount input by the joint purchaser is the amount received by the receiving unit 12.

  (Step S516) The burden amount determination unit 133 stores the amount input by the joint purchaser in the joint purchaser information storage unit 112 in association with the purchaser identifier of the i-th joint purchaser. It is assumed that the amount input by the joint purchaser is received by the receiving unit 12 and stored in the storage unit 11 by the processing unit 13. Further, the amount input by the joint purchaser is stored in association with the purchaser identifier.

  (Step S517) The burden amount determination unit 133 increments the counter i by 1. The process returns to step S515.

  Next, the attribute value variation method processing of step S512 will be described using the flowchart of FIG. In FIG. 6, the description of the same processing as that in the flowchart of FIG. 5 is omitted.

  (Step S <b> 601) The burden amount determination unit 133 substitutes 1 for a counter i.

  (Step S602) The burden amount determination unit 133 determines whether there is an i-th joint purchaser. If the i-th joint purchaser exists, the process goes to step S603, and if not, the process goes to step S506. The burden amount determination unit 133 examines the joint purchaser information storage unit 112 to determine whether or not the i-th joint purchaser exists.

  (Step S <b> 603) The burden amount determination unit 133 acquires the attribute value of the i-th joint purchaser from the joint purchaser information storage unit 112. Note that the attribute values acquired here are attribute values (for example, gender, job title, age, etc.) included in the sharing rule to be applied.

  (Step S604) The burden amount determination unit 133 applies the attribute value acquired in step S603 to the sharing rule, and determines the burden amount of the i-th joint purchaser.

  (Step S605) The burden amount determination unit 133 increments the counter i by 1. The process returns to step S615.

  In the flowchart of FIG. 6, the determination algorithm for the burden amount does not matter. In the flowchart of FIG. 6, the burden amount for each person is determined, but the burden amount for all members may be determined by parallel processing.

  Next, another process of step S307 will be described with reference to the flowchart of FIG.

  (Step S <b> 701) The payment process incomplete person information acquisition unit 136 determines whether it is a notification timing to a payment process incomplete person. If it is a notification timing, it will go to step S702, and if it is not a notification timing, it will go to step S705. Note that the notification timing may be set periodically (for example, every day at 7:00 or the like), or even a predetermined time before the settlement deadline stored in the joint purchaser information storage unit 112 or means not shown. It may be good or immediately after receiving the payment information from the representative. Note that there may be two or more notification timings a predetermined time before the settlement deadline.

  (Step S <b> 702) The payment processing incomplete person information acquisition unit 136 uses the payment information stored in the payment information storage unit 118 and the joint purchaser information stored in the joint purchaser information storage unit 112 to perform payment. The payment processing incomplete person information which is information of the joint purchaser who has not transmitted the information is acquired. And the payment prompt transmission part 143 comprises the message which prompts a payment process using payment process incomplete person information. When there are two or more payment processing incomplete persons, the payment prompt transmission unit 143 may form a different message for each of two or more payment processing incomplete persons, or may form the same message. .

  (Step S703) The payment reminder transmitting unit 143 acquires one or more pieces of notification destination information included in the one or more pieces of payment processing incomplete person information acquired in Step S702.

  (Step S704) The payment prompt transmission unit 143 transmits the one or more messages configured in Step S702 to the terminal device 2 of the person who has not completed the payment process indicated by the one or more pieces of notification destination information acquired in Step S703. Return to upper process.

  (Step S705) The settlement information deletion unit 138 determines whether or not the settlement process has expired. If the settlement process has expired, the process proceeds to step S706, and if the settlement process has not expired, the process proceeds to step S710.

  (Step S706) The transmission unit 14 composes a message that the time limit for the settlement process has passed.

  (Step S707) The transmission unit 14 acquires the notification destination information of the representative from the joint purchaser information storage unit 112.
