1 shows an operating system for parcel delivery management according to embodiments of the present invention. Referring to FIG. 1 , an operating system (hereinafter referred to as operating system) 10 for parcel delivery management may receive a delivery request from the shopping mall server 100 and provide a delivery service corresponding to the delivery request.

The operating system 10 may include a shopping mall server 100 , an operating server 200 and a person in charge terminal 300 . The operating system 10 may provide a courier service corresponding to a delivery request from the shopping mall server 100 . In addition, the operating system 10 has an effect of verifying an error in a delivery address corresponding to a delivery request transmitted from the shopping mall server by using information transmitted from the shopping mall server 100 . This will be described later.

The shopping mall server 100 is a server that operates a shopping mall and may be a server that manages a shopping mall page that sells products or services for free or for a fee. Users can access and log in to a shopping mall page operated by the shopping mall server 100 and purchase goods or services. At this time, the user (ie, the buyer) transmits the delivery address to which goods or services are to be delivered to the shopping mall server, and the shopping mall server generates a delivery request including the delivery address and transmits it to the operation server 200 .

Meanwhile, in this specification, a shopping mall is used as an example, but embodiments of the present invention cover not only shopping malls but also all items requiring (required) delivery service to a specific delivery address.

The shopping mall server 100 may store information of members subscribed to the shopping mall managed by the shopping mall server 100 . At this time, information of members can be distinguished into identification information and non-identification information. Identification information is information that can identify who a member is (ie, personal information), and may include, for example, a resident registration number, a name, a mobile phone number, and the like. Non-identifying information is information that cannot identify who a member is, and may include, for example, whether or not an address has been changed and whether or not a product has been returned. Under current law, special care is required for the processing and storage of identification information such as personal information.

According to embodiments, the shopping mall server 100 may include log-in history information and order history information of members. The log-in history information may include log-in dates of members and information on whether an address has been changed on the log-in date. The order history information may include information about order dates of members, corresponding returns dates, and reasons for returns.

The shopping mall server 100 may transmit login history information and order history information of members to the operation server 200 . At this time, the shopping mall server 100 may de-identify the login history information and the order history information and transmit them to the operation server. Here, de-identification means processing so that each member cannot be identified by deleting personal information included in each information. According to embodiments, the shopping mall server 100 may generate a non-identification code corresponding to each member, and generate login history information and order history information using the generated non-identification code. For example, the shopping mall server 100 may generate login history information and order history information based on the generated non-identification code.

For example, de-identified login history information includes member's non-identification code, log-in date, and address change, but non-identification code is a simple code such as a number to identify members and can identify members' personal information. Therefore, de-identified login history information may not include information about which member logged in and changed address. That is, it is not possible to determine the log-in date and address change of a specific member with de-identified log-in history information.

The operating server 200 may exchange data with the shopping mall server 100 . According to embodiments, the operation server 200 may receive a delivery request including a delivery address from the shopping mall server 100 . The operating server 200 may provide a delivery service corresponding to the delivery request to the shopping mall server 100 using the delivery address.

For example, the operation server 200 may assign a delivery person in charge corresponding to the corresponding delivery request and transmit a delivery service service request to the terminal 300 of the person in charge of the assigned delivery person. At this time, the request for providing the delivery service may be a request instructing collection and delivery of the corresponding delivery service.

The person in charge terminal 300 is a terminal of a person in charge of a courier service that provides a courier service, and may receive a courier service provision request from the operation server 200 . In addition, the person in charge terminal 300 may transmit a notification or request related to the courier service to the operation server 200 . For example, the person in charge terminal 300 may transmit a notification indicating change of delivery address, change of collection address, completion of delivery, completion of collection, etc. to the operation server 200 .

The operation server 200 according to embodiments of the present invention may verify an error in a delivery address included in a delivery request. A delivery request transmitted from the shopping mall server 100 is generated based on delivery addresses input by members of the shopping mall server 100 . At this time, when the members enter the wrong shipping address due to a mistake or typo, the shipping address delivered by the delivery request is also wrongly delivered, resulting in a situation where the parcel is delivered by mistake. On the other hand, errors in the shipping address can be easily distinguished through error verification, but it is difficult to easily determine if the shipping address is entered incorrectly by mistake. Most of the cases where the delivery address is entered incorrectly by mistake are cases where the address before moving is entered after moving.

The operation server 200 according to embodiments of the present invention determines whether the delivery address included in the received delivery request is the address before moving by using the login history information and order history information of the members from the shopping mall server 100. , the shipping address can be verified. In particular, the operation server 200 can verify the shipping address using login history information and order history information that do not include identification information, so there is no concern about leakage of personal information of members, and to store and store identification information. It has the effect of reducing the cost incurred.

Also, the memory 230 may store a delivery request, login history information, and order history information received from the shopping mall server 100 .

3 shows login history information according to embodiments of the present invention. Referring to FIG. 3 , the shopping mall server 100 may generate and store log-in history information including log-in dates of members and information on whether an address has changed on the log-in date. That is, the shopping mall server 100 may store and manage log-in history information of its members. Here, the log-in date means the date the member logs in to the shopping mall server, and whether or not the address has been changed indicates whether the logged-in member has changed his/her own address information stored in the shopping mall server.

The shopping mall server 100 may de-identify the login history information and transmit the de-identified login history information to the operation server 200. Accordingly, the operating server 200 cannot determine whether a specific member's login date or address has been changed through the login history information transmitted from the shopping mall server 100 .

For example, as shown in FIG. 3, the de-identified log-in history information includes log-in dates of members corresponding to non-identification code '1', '2021-04-21', '2022-03-21', and '2022-03-21'. It only indicates '2022-05-21', but does not include information that can identify the member, such as the member's name, resident registration number, or mobile phone number.

4 is a diagram for explaining an address change period according to embodiments of the present invention. Referring to FIG. 4 , the operation server 200 may determine an address change period (Tac, Tac') of each member of the shopping mall server using login history information.

The operation server 200 leads the login date and address change of the members of the shopping mall server 100 included in the login history information, and for each member, the login date when the address was changed and the address change immediately before that. The address change period (Tac, Tac') of each member defined by the difference in log-in date may be determined.

For example, the first date (t1), the fourth date (t4), and the sixth date (t6) in FIG. 4 represent logins with address changes, and the second date (t2), the third date (t3) and The fifth date (t5) represents login without address change. In this case, a period between the first date t1 and the fourth date t4 may be determined as the address change period Tac.

Meanwhile, the number of address change periods (Tac, Tac') may be plural. For example, a period between the fourth date t4 and the fifth date t6 or an additional address change period Tac' may be determined. At this time, the operation server 200 may use the average of a plurality of address change periods (Tac, Tac') existing for each member, or use the latest address change period (Tac, Tac').

5 shows order history information according to embodiments of the present invention. Referring to FIG. 5 , the shopping mall server 100 may generate and store order history information including information related to orders of members. That is, the shopping mall server 100 may store and manage order history information of its members.

The order history information may include information about each member's order date, return date, and reason for return. The date of order is the date on which the member orders goods or services, the date of return is the date of requesting a return corresponding to the order, and the reason for return indicates the cause of the return. At this time, if there is no return of a specific order, the return date and reason for return are blank.

The shopping mall server 100 may de-identify the order history information and transmit the de-identified order history information to the operation server 200 . Accordingly, the operation server 200 cannot determine a specific member's return date or reason for return through the order history information transmitted from the shopping mall server 100 .

For example, as shown in FIG. 5, in the de-identified order history information, the member's order date corresponding to the non-identification code '1' is '2021-12-19' and '2022-05-19' , It only indicates that the return date corresponding to the order date '2022-05-19' is '2022-05-21' and the reason for return is 'Wrong delivery address', and the member's name, resident registration number, mobile phone number, etc. It does not contain any identifying information.

6 is a diagram for explaining an address maintenance period according to embodiments of the present invention. Referring to FIG. 6 , the operation server 200 may determine address retention periods (Tam, Tam') of each member of the shopping mall server using order history information.

The operation server 200 determines the return date for which the return reason is an incorrect shipping address from the order history information, and the address retention period of each member (Tam, Tam') can be determined.

For example, in Figure 6, the first order date (O1), the second order date (O2), the second return date (R2) corresponding to the second order date (O2), the third order date (O3) and A third return date (R3) corresponding to the third order date (O3) is shown. At this time, it is assumed that all returns have an incorrect shipping address as a reason for return. In this case, a period between the second order date O2 corresponding to the second return date R2 and the first order date O1 immediately before that date may be determined as the address retention period Tam.

Meanwhile, the number of address maintenance periods (Tam, Tam') may be plural. For example, a period between the third order date O3 corresponding to the third return date R3 and the immediately preceding second order date O2 may also be determined as an additional address retention period Tam'. At this time, the operation server 200 may use the average of a plurality of address retention periods that exist for each member or use the address change period at the latest point in time.

7 is a diagram for explaining the operation of the operation server according to embodiments of the present invention. Referring to FIG. 7 , the operating server 200 may verify a delivery address included in a delivery request transmitted from the shopping mall server 100 using login history information and order history information. According to embodiments, the operation server 200 may calculate the probability that the delivery address included in the delivery request, that is, the delivery address is an error, and verify the delivery address based on the calculated probability.

The operating server 200 receives login history information and order history information from the plurality of servers 100 including the first shopping mall server (S110). According to embodiments, the operating server 200 receives login history information and order history information from the plurality of servers 100 periodically or in real time. At this time, the login history information and order history information may be non-identified information.

The operation server 200 receives a delivery request associated with the first member from the first shopping mall server 100-1 (S120). According to embodiments, the delivery request may include information about the delivery address of the first member. Also, according to embodiments, the delivery request may include information about the first member's delivery address and the non-identification code of the first member. The first shopping mall server 100-1 may store the non-identification code of the first member generated in the process of de-identifying the log-in history information and order history information.

Operation server 200 may calculate the critical period (S130). The critical period is a period that is a reference period for modifying (ie, updating) a member's address stored in the shopping mall server. If it exceeds , it is determined that the member's address needs to be corrected, and the delivery address based on the member's address before correction may be determined to be in error.

The operation server 200 may determine the threshold period using the log-in history information and order history information transmitted from the shopping mall server 100 .

The operating server 200 may determine the first critical period by using the log-in history information. According to embodiments, the operation server 200 leads the log-in date and address change of the members of the shopping mall server 100 included in the log-in history information, and for each member, if there was an address change performed by the user Determine the address change period of each member, which is defined as the difference between the most recent log-in date and the log-in date of the address change performed by the user immediately before that, and determine the first threshold period using the address change periods of the members. there is.

Meanwhile, a plurality of address change periods may be defined for each member by definition. The shopping mall server 100 uses the average of a plurality of address change periods that exist for each member, or the latest address change period. is available.

The operation server 200 may determine the first threshold period by using an average of address change periods of members of the shopping mall server 100 . Alternatively, the operating server 200 may determine the first threshold period by using a weighted average of address change periods of members of the shopping mall server 100 . According to embodiments, the operation server 200 may determine the first threshold period by applying a weight associated with the number of log-ins of each member to the address change period. Members who log in more times tend to reflect their address changes immediately, so by reflecting the address change period of such members higher, it will contribute to more accurately measuring the first critical period related to address changes. can For example, the operating server 200 may calculate the first critical period according to Equation 1 below.

Here, T _th1 is the first threshold period, N is the number of members of the shopping mall server, M _i is the total number of logins of the ith member of the shopping mall server, M is the average number of logins of members of the shopping mall server, and T _{ac ,i} is the address change period of the ith member. As described above, T _ac,i may be an average of a plurality of address change periods of the i-th member or an address change period at the most recent point in time.

The operation server 200 may determine the second critical period by using the login history information and the order history information. According to embodiments, the operation server 200 defines the difference between the order date corresponding to the most recent return history in which the return reason is recorded as an incorrect shipping address from the order history information and the order date that was successfully delivered immediately before the return history. An address retention period of each member may be determined, and a second critical period may be determined using the address retention periods of the members. That is, the difference between the order date at the time of return of a member with a return history and the date of an order for delivery completion immediately before that date is determined as the address maintenance period, and the address change time point can be inferred from the return history.

Meanwhile, a plurality of address retention periods may be defined for each member by definition. The shopping mall server 100 uses the average of a plurality of address retention periods existing for each member, or the address retention period at the latest point in time. is available.

The operation server 200 may determine the second threshold period by using the minimum value of the address maintenance period of the members of the shopping mall server 100 . Or, alternatively, the operation server 200 may determine the second threshold period using a weighted average of address maintenance periods of members of the shopping mall server 100 and a minimum value of address maintenance periods. Since the address retention period is determined based on the return history as described above, the address retention period indicated by the return history tends to appear much later than the actual address retention period. Accordingly, when the second threshold period is determined by considering the minimum address retention period, accuracy is higher.

According to embodiments, the operation server 200 may determine the second threshold period by using a weight associated with the number of log-ins of each member and a minimum value of an address maintenance period. For example, the operation server 200 may calculate the second critical period according to Equation 2 below.

Here, T _th2 is the second threshold period, N is the number of members of the shopping mall server, M _i is the total number of logins of the ith member of the shopping mall server, M is the average number of logins of members of the shopping mall server, and T _{am ,i} is the address retention period of the ith member, and min(T _am,i ) is the minimum address retention period for all members. As described above, T _am,i may be an average of a plurality of address retention periods of the i-th member or an address retention period at the latest point in time.

The operation server 200 may calculate the critical period using the first critical period and the second critical period. According to embodiments, the operation server 200 calculates the critical period using an average of the first critical period and the second critical period, or calculates the critical period using the minimum and maximum values of the first critical period and the second critical period. can be calculated.

Specifically, for example, the critical period T _th may be calculated according to Equation 3 below.

In Equation 3, min(T _th1 , T _th2 ) is the minimum value of the first critical period and the second critical period, max(T _th1 , T _th2 ) is the maximum value of the first critical period and the second critical period, avg(T _th1 , T _th2 ) is an average value of the first critical period and the second critical period.

The operating server 200 may determine a period of non-change of the address of the first member corresponding to the delivery request (S140). According to embodiments, the operation server 200 uses the non-identification code and log-in history information of the first member included in the delivery request transmitted from the first shopping mall server 100-1, so that the address of the first member is not changed. period can be determined.

For example, the operation server 200 may determine the address non-change period by calculating the difference between the current date and the latest address change date of the first member based on log-in history information.

The operating server 200 may verify an error in the shipping address by comparing the calculated critical period with the period of no change in the address of the first member (S150). For example, the operation server 200 determines that the delivery address included in the first member's delivery request is highly likely to have an error when the first member's address non-change period exceeds the critical period, thereby Errors can be verified.

According to the foregoing embodiments, the operation server 200 may transmit a notification requesting reconfirmation of the delivery address to the first member when it is determined that the delivery address has a high probability of being erroneous. In addition, the operation server 200 may request the first member to update the delivery address, and may correct the delivery request by updating the delivery address by reflecting the update of the delivery address transmitted from the first member.

When the delivery request is corrected, the operation server 200 may designate a courier service manager corresponding to the corrected delivery request again. For example, the operation server 200 may newly assign a delivery service person in charge corresponding to the updated delivery address and transmit a delivery service provision request to the newly assigned person in charge terminal 300 .

According to the embodiments of the present invention, a member with a high possibility of address change is identified in advance and a notification requesting reconfirmation of the member's shipping address is provided, resulting in misdelivery due to incorrect shipping address or non-reflecting of changes. It has the effect of significantly reducing the cost loss.

The methods according to the present invention may be implemented in the form of program instructions that can be executed by various computer means and recorded on a computer readable medium. Computer readable media may include program instructions, data files, data structures, etc. alone or in combination. Program instructions recorded on a computer readable medium may be specially designed and configured for the present invention or may be known and usable to those skilled in computer software.

Examples of computer readable media may include hardware devices specially configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like.
