In this case, if the information on the delivery price selected by the purchasing user is the same, the user may determine the delivery price when purchasing the product. In this case, the higher the delivery amount, the faster the order of delivery may be, and accordingly, the highest weight may be assigned. However, since the delivery order or time may vary depending on the product, in the case of the delivery price information, the order can be set to be differentially determined within the product type of the same product according to the nature of the product.

The price information of the product purchased by the user is about the price of the product purchased by the user, and may be set so that the more expensive the product, the more preferentially delivery is performed.

The release schedule information of the same product as the product corresponding to the purchased user is determined by the user purchasing a specific product of socks in one embodiment and other 10 user terminals purchasing the same specific product earlier than this, other user terminals If the purchased 10 socks have not yet been shipped, it may be set to be delivered with priority among the 10 socks, and then placed in a lower priority after considering the delivery date and time. That is, a value for the number of products that should be delivered with priority over the product purchased by the user may be substituted among the expected shipment information of products such as the product corresponding to the purchased user. It may be set so that the weight is low, that is, inversely proportional or inversely proportional to the weight.

The purchase time information is information about the time the user finally proceeded to the payment, and can be set so that a value in inverse proportion to the time until the previous payment has been made is substituted using the present at the time the server calculates as a reference point.

At this time, the server may determine a delivery method so that the higher the priority delivery number, the higher the priority delivery. In this case, a delivery order value may be derived based on the priority delivery value, and a delivery method may be determined so that the higher the delivery order value, the higher the delivery value. At this time, the delivery order value may be derived by Equation 2 below.

In addition, the server may set the delivery order value to be high in a specific region, the server may obtain information about donation details in the meantime from the user terminal, and the donation amount is high based on the donation details for a predetermined second period. The delivery order value can be set to be higher, and after obtaining schedule information from the user terminal, the delivery order value can be set to be higher for urgent schedules (a schedule with fewer days remaining can be set as an urgent schedule). . At this time, the server may evaluate the reliability of the relationship between the schedule and the purchased product in order to secure reliability of the schedule. At this time, the reliability of the association may be set to be evaluated in a predetermined method, and at least three predetermined methods may exist. Screenshots can be used as one method, and screenshot information on reservations, visit reservations, or participation application documents included in the screenshots can be obtained, and by using the OCR function, information on the actual date is firstly determined. After acquiring the information, it is compared with the schedule information obtained from the user terminal to determine whether or not the user actually participates in the schedule. Then, after determining whether the purchased product is included in the required product included in the corresponding screen shot, if it is included, the reliability of the association may be set to be high. At this time, the OCR function can be used as well, and if the above corresponding information is not read by the OCR function, a message urging the user to make a verification phone call may be transmitted.

In addition, the server may decide to select various means such as airplane, truck, train, etc. as a delivery method. At this time, if delivery must be completed within a specific time according to the delivery order, it can be set to use a fast means of transportation such as an airplane. It can also be determined by taking into consideration the air transport time and the like. In addition, the server may determine a grade as one of predetermined grade categories based on the user's purchase details, and may set a delivery order value to be reflected according to the corresponding category.

Through this formula, the server can give shipping benefits to buyers who have made a lot of purchases in the meantime, and furthermore, it is proportional to the priority delivery figure, so that a reasonable delivery method can be selected by determining the delivery method based on the priority delivery figure and various conditions. can You can also give customers more benefits in terms of delivery, which will encourage them to buy more products and increase sales.
