Description

Building rental management based official letter sending service system {SYSTEM FOR PROVIDING RENTAL PROPERTY MANAGEMENT BASED OFFICIAL LETTER SENDING SERVICE}

The present invention relates to a system for providing a service for sending official documents based on building lease management, and provides a platform that automatically extracts cases in which an event different from a lease agreement occurs in building lease management and sends an official letter to a lessee as an action of the lessor.

According to the recent survey on housing conditions, the majority of leases in Korea are occupied, and the share of leases has remained unchanged for decades, and leases can be seen as a common type of housing for the common people. In the rental market, the demand for conversion from jeonse to monthly rent is increasing, and the number of single-person households is also increasing, and household types are rapidly changing or being reorganized. The change in the proportion of leases and the lease structure is an environment that can cause more disputes in the confrontational lease contract structure. In fact, the proportion of litigation cases related to the court's lease is showing an increasing trend. In Korea's lease, the cascade of inconsistency between moving out and moving in, seasonal repair maintenance requirements such as freezing and breakdown, boiler, mold, etc., lack of laws, and conflict with the lessor Disputes continue due to tenants' failure to fulfill their respective obligations. Social problems have been steadily raised, but the way to resolve disputes so far is mostly resolved through lawsuits or abandoned.

At this time, a platform that regulates the obligations between the lessor, the lessee, and the manager and automates the implementation was researched and developed. is extracted and stored in the contract management database, the manager and the lessor, and the rental building information of the lessor are stored, and the tenant information and the leased building information are registered, and a payment notification message is sent according to the set cycle, and an overdue information notification is sent in case of overdue to record and store payment details and overdue details, request to move out before expiration or upon arrival of maturity, notify the landlord of a change in rental conditions, and proceed with renewal and cancellation of the contract requesting acceptance and adjustment of the changed conditions, and move out of the tenant Through the process of processing and registering new tenants, the lessor and the lessee are connected to each other, and the lessee's payment details and overdue information notices during the lease period, notification of expiration, contract renewal and cancellation, and lessee's move-out notice are mutually shared and read to communicate with the lessor. A configuration for preventing disputes between tenants in advance and performing smooth rental management is disclosed.

However, even if the above configuration is used, the lease contract is written in writing and stored with a seal or seal on the system, so mistakes that may occur in the process of separately entering the lease contract and managing the contents or manual entry by manpower It comes as a big burden to managers who manage multiple rental properties in that they have to do it. Also, when a problem with the rental contract occurs, it is when there is a difference between the contract details and the actual event. There are cases in which disputes do not end because the highest requirements are not met or evidence is not met, such as arbitrarily writing and sending text messages because there is no official document format. Accordingly, the text in the rental agreement is automatically recognized and the contract details are saved, the lessor is automatically notified when a gap between actual events occurs, and an official document format corresponding to the action of the lessor exists, so that mutual communication between Research and development of a platform that can prevent escalation of conflict as much as possible is required.

In one embodiment of the present invention, the rights and obligations of the lessor and the lessee, which exist in one cycle from before signing the contract to the end of the contract, are defined and made into a database, respectively, and the rental period, rental purpose, use Management repair, cancellation of contract, default of debt and compensation for damages, cancellation of contract, termination of contract, settlement of expenses, etc. The text of the agreement between the parties written in the lease contract is extracted and stored, and if the event that has occurred does not conform to the terms of the contract By automatically notifying the lessor, after waiting for the lessor's action, if the lessor chooses an action, a format corresponding to this is provided, or by filling in the information corresponding to the action in a pre-stored format and sending it to the lessee as an official letter, it is possible to speak face-to-face. It is possible to provide a method of providing an official letter sending service based on building rental management, which can prevent damage between parties due to an emotional fight by sending an official letter that can maintain a dry tone. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention uploads a rental agreement and receives a rent overdue notice when the rent described in the rental agreement is not deposited on a preset date, A storage unit that collects and stores contract data by OCR (Optical Character Recognition) after receiving the lease contract from the lessor terminal and the lessor terminal that selects and transmits an action including contract termination notice or content certification notice, and lease contract A monitoring unit that checks whether or not the rent is deposited to the lessor's account number registered on the pre-set date, a transmission unit that sends a rent overdue notice to the lessor's terminal if the rent is not deposited to the account number, and an action selected from the lessor's terminal Including an official document management unit that automatically fills in the lessor information, lessee information, and the amount and number of overdue rents written in the lease contract in an official document format that has been mapped to and stored in advance and transmits a notice of contract termination or a notice of content certification to the lessee's terminal It includes an official letter sending service providing server.

According to any one of the above-described problem solving means of the present invention, the rights and obligations of the lessor and the lessee, which exist in one cycle from before signing the contract to after the contract is terminated, are defined and made into a database, respectively, and The text of the agreement between the parties written in the rental agreement, including the period, purpose of rental, use management and repair, cancellation of the contract, default and compensation for damages, cancellation of the contract, termination of the contract, and settlement of expenses, is extracted and stored. In case of non-compliance with the terms of the contract, the lessor is notified automatically, waiting for the lessor's action, and if the lessor chooses an action, the corresponding format is provided or the information corresponding to the action is filled in the pre-stored format and sent to the lessee in an official document By doing so, it is possible to prevent damage between the parties by spreading into an emotional fight by sending an official letter that can maintain a dry tone compared to when speaking face-to-face.

It is a drawing for explaining an example.

Referring to FIG. 2, the official document sending service providing server 300 includes a storage unit 310, a monitoring unit 311, a transmission unit 313, an official document management unit 315, an integrity certification unit 320, and a management fee collection unit. (330), Contract Cancellation Department (340), Printing Department (350), Reporting Department (360), Smart Contract Department (370), Brokerage Request Department (380), Living Management Department (390), and Tenant Selection Department (391). can include

The official letter sending service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with at least one lessor terminal 100, at least one lessee terminal 400, and at least one manager In the case of transmitting a building rental management based official letter sending service application, program, app page, web page, etc. to the terminal 500 and at least one intermediary terminal 600, at least one lessor terminal 100 and at least one lessee terminal (400), at least one manager terminal 500 and at least one intermediary terminal 600 may install or open a building rental management-based official letter sending service application, program, app page, web page, and the like. In addition, a service program is executed in at least one lessor terminal 100, at least one lessee terminal 400, at least one manager terminal 500, and at least one broker terminal 600 by using a script executed in a web browser. may be driven. Here, the web browser is a program that allows users to use the web (WWW: World Wide Web) service, and means a program that receives and displays hypertext described in HTML (Hyper Text Mark-up Language). For example, Netscape , Explorer, Chrome, and the like. In addition, an application means an application on a terminal, and includes, for example, an app running on a mobile terminal (smart phone).

Referring to FIG. 2 , the storage unit 310 may collect and store contract data through OCR (Optical Character Recognition) after receiving a rental contract from the lessor terminal 100 . At this time, the lease contract is prepared by the Ministry of Justice as a standard contract in FIGS. 4a and 4b, and is intended to be used in housing leases or commercial leases. At this time, each column and item are designated in the standard contract, and a column is provided to describe the matters agreed upon by both parties. The format of the field to be written has already been set, so the coordinates (x, y) are constantly prepared. After setting each coordinate and item, just read the text from each coordinate with OCR, and type the rental contract separately. Even if you don't do it, you can extract and digitize each contract. If the text is typed, it is easily extracted by OCR, but if it is not, that is, if it is written by hand, errors are likely to occur in the process because handwriting must be identified.

Accordingly, the storage unit 310 according to an embodiment of the present invention allows the rental contract to be written using a smart pen, and allows handwriting input with the smart pen to be input and digitized. OCR stands for Optical Character Recognition and converts handwritten or printed characters into mechanized text. The accuracy of OCR varies greatly depending on the type and language of the data provided. Unlike a language in which one phoneme is one letter, such as Latin, more learning data is required for a form in which consonants and vowels are combined, such as Hangul, because of its complex structure. At this time, the overall operation process of the OCR program first identifies the area estimated to be a letter in the image as a paragraph through the detection process, and stores the position information of the rectangle surrounding the corresponding paragraphs. In the process of prediction, an object containing the position corresponding to each phoneme in the paragraph is created. Through the trained model, we find the initial consonants, neutral consonants, and final consonants expected for each object. Each object is combined into one letter and converted into a letter with the highest matching rate through a semantic analysis process. Finally, the letters obtained by repeating this process are combined and reconstructed into paragraphs to be output.

At this time, Tesseract OCR Engine can be used. Tesseract is an optical character recognition open source engine. In the storage unit 310 of the present invention, a process of analyzing a text image using the Tesseract OCR engine and delivering the resultant value to the user can be performed. When an image is given as an input, the process of recognizing characters through preprocessing and character border identification is carried out step by step. The method according to an embodiment of the present invention requires hardware including a camera module for obtaining a text image and software for OCR analysis. In addition, we need an application that receives the result value processed by the software and provides it to the user. First, the text is read in video format through the camera built into the smart pen. It is divided into frames and transmitted to the mobile device, and each image is pre-processed for accurate recognition. The pre-processing process goes through binarization, which represents only white and gray images, and LPF (LowPass Filter), which blocks high frequencies. In addition, depending on the situation, more sophisticated image preprocessing can be targeted using techniques such as median filtering, background removal, verticalization, and bounding boxes. After preprocessing, string recognition is performed using the Tesseract OCR engine. The device can output the corresponding recognition result as a string in the application, and the user (lessor and lessee) can check the output result in real time.

In the case of Tesseract OCR, since character recognition is performed based on pre-trained standard fonts, an advanced strategy to improve accuracy according to fonts is required. For advancement, it is possible to use a method of creating and training a deep learning neural network using the Tenserflow layer. In other words, after securing the data for the font and language you want to learn, train it in the direction of increasing the accuracy of Tesseract OCR. After the iterative learning process, the process of verifying the results using test data is carried out. In particular, in the case of Tesseract OCR, since the accuracy of Korean recognition is low, an advanced strategy through deep learning can be useful. At this time, since the smart pen can not only read letters but also sequentially recognize letter strokes (frame-by-frame confirmation), recognition results can be further improved through this. Here, since there are many similar characters due to the characteristics of Hangul, recognition can be learned using the Hangul cursive database.

In summary, in the image pre-processing, the image can be taken through the camera module and transmitted to the application using the Wi-Fi module. Note the application of erosion, dilatation and binarization techniques. Through this, we were able to derive the desired string part. Next, in string recognition (OCR), it can be processed based on Tesseract OCR, and even some distorted characters can be accurately recognized.

The monitoring unit 311 may check whether or not the rent is deposited on a preset date using the account number of the lessor registered in the lease contract. Looking at the rent (monthly rent) part in [contract details] of FIG. 4a, since it is stated that the gold XXX expedition is paid on the XX day of every month, it is possible to check whether the monthly rent XXX is deposited on the XX day of each month through the account. can At this time, the monitoring unit 311 may use an open banking API, and open banking refers to an infrastructure that provides financial services of a bank in a standardized form so that fintech companies can conveniently develop financial services. Instead of a financial institution, it provides services such as querying customers' financial information or allowing them to transfer money instead. In Korea, pilot operation began in October 2019, and the service officially started in December of the same year. Accordingly, the monitoring unit 311 monitors whether or not the deposit is made using the open banking API and obtains the evidence data. Likewise, management costs can be monitored in this way. If there is a management fee deposit account, you can use the open banking API to monitor whether the lessee has deposited the management fee and whether the deposited management fee is accurate.

The transmitter 313 may transmit a chime overdue notice to the lessor terminal 100 when the chime is not deposited into the account number. At this time, it is possible to wait for an action of the lessor terminal 100 while notifying the chime overdue. The form of the notice of overdue chime is irrelevant (e-mail, text message, postal mail, etc.), and the evidence is recognized as having done the best. Or, there are cases in which evidence cannot be submitted due to inability to keep mail, or evidence cannot be attached even when requesting a payment order, which is the simplest method of civil litigation. In addition, when the chime overdue notice is used as digital evidence, it may be asserted that the chime overdue notice did not reach the lessee's terminal 400 or was forged or altered. Accordingly, the lessor terminal 100 uploads the lease contract and receives a rent overdue notice when the rent described in the lease contract is not deposited on a preset date, and includes a contract termination notice or content certification notice for the overdue rent Actions can be selected and transmitted.

The transmission unit 313 must ensure that the transmitted chime overdue notification is not forged and altered and is the same as the original data. At this time, it is assumed that the hardware can trust itself. The transmission unit 313 may record a network communication record when the chime overdue notification is transmitted and a kernel system call record together. After the fact, based on this log, it is possible to prove that the background program did not operate during the process of storing the data received through the network in the storage medium and that the data was transmitted as it is. Since we have proven that there is no background program, we now need to check whether the data has been forged or tampered with in the transfer tool itself. This can be done by comparing the preserved packets with the transmitted data. In addition, network packets generated during the transmission process include data that cannot be modified by the transmission system, such as retransmission records, IP addresses where actual data was sent and received, and public key-based authentication information, in addition to the data constituting the content. It can also be detected by checking . Independence of data can be guaranteed by installing the location of network packet collection in the input/output terminal of the network interface, which cannot be involved in programs running in the transmission system, rather than in the transmission system. In order to ensure that the finally collected data is not forged or falsified, the transmission system itself is preserved so that it can be audited later.

To this end, a virtual machine may be used to configure a transmission system in which reliability is guaranteed in the transmission unit 313 . In addition, to ensure the reliability of the transmission process, it is possible to build a system and network monitoring environment in which records of processes executed in the transmission system, network connection records, and file input/output are recorded. At this time, the behavior recording system is first installed and operated so that the process of establishing the network monitoring environment can be verified. First, a virtual environment is constructed in which only system files for driving the operating system and application programs installed together with the operating system exist for convenience. At this time, the operating system to be installed also records and stores the file used for installation, version information, and hash value of the installation file so that it can be verified later. If a virtual environment is built and transmitted in it, the transmission environment itself can be separated and stored. In this way, even when transmitting over a long period of time, the transmission environment can be stopped for a while and then started and transmitted when transmission is necessary. In addition, due to the nature of building a virtual environment, if it is built only once, it can be operated at any time when transmission is required to respond to urgent transmission.

The official document management unit 315 automatically writes the lessor information, the lessee information, and the amount and number of overdue rents written in the lease agreement in the official document format previously mapped and stored to the type of action selected from the lessor terminal 100, and the lessee terminal of the lessee. A notice of contract termination or a notice of proof of contents may be transmitted to (400). For example, in the case of notification of content verification, since the format of the official document is set as shown in FIG. 4c, only the contents to be entered in each item are entered as the contents extracted from the rental contract and the contents monitored by the monitoring unit 311. Of course, the official document format of the content certification notification is not limited to FIG. 4C and various official document formats may exist. In the case of tagging metadata for each item and putting the tagged metadata in each item, the lessor can create content certification documents in the official document management unit 315 without having to prepare the documents himself or request a law firm. At this time, the agent (Agent ) can be used.

An agent is a type of computer program whose dictionary definition is an autonomous process that performs tasks on behalf of a user for a specific purpose. It is assumed that the agent has a knowledge base and reasoning function, and it has the characteristics of taking appropriate actions according to the environment and learning and developing through experience. Therefore, the agent does not passively perform the given task, but has an active characteristic to find and carry out the task necessary to achieve the goal. In addition, the action of the agent is not completed all at once, but continuously.

A web agent mainly refers to a computer program that is located in a virtual space environment called the Internet and helps users handle special applications to automate repetitive tasks. Because of the aspect, when these repetitive tasks are handled by an agent, the efficiency can be maximized, such as saving time and fundamentally blocking the possibility of mistakes. The concept of a Personal Assistant Agent (PA for short), especially a Specialized PA, is used to assist users in carrying out certain specific tasks. Suggests websites to visit. Another type of PA memorizes user usage patterns, such as opening directories or text editors, and predicts future actions. At this time, an expert system using a rule-based reasoning engine may also be added. The rule-based inference technique sets conditions to be satisfied (match), finds rules that satisfy the specified conditions, selects the best rule (Select or Conflict Resolving), and executes it, and may generate satisfaction of new conditions. Since this method has a form suitable for implementing a context-awareness-based service that selects an appropriate service for a given situation, it can be used for repetitive and typical contents such as sending official letters, enabling automation.

When reading the lease contract uploaded from the lessor terminal 100 by OCR, the integrity certification unit 320 arranges the lease contract received from the lessee terminal 400 side by side so that the seal stamped in the lessee information column and the lessor information column It is possible to read whether the first partial seal of the lease contract of the rental terminal and the second partial seal of the lease contract of the lessee terminal 400 are the same as those connected. In general, if there are two copies of the contract, the landlord and the lessee place the two copies side by side and stamp or sign them. At this time, in consideration of the case where the lease contract brought by the lessor has been falsified or the case where the lease contract brought by the lessee has been falsified, check whether the data written in each item of the two contracts match, and put the two side by side and seal or In the case of attaching a signature, it is to check whether it is the same as the seal or signature stamped or written in the signature or seal column at the bottom of FIG. 4b. If the two seals joined together match the seals at the bottom of FIG. 4B , the integrity of the two contracts can be proven not to be counterfeited.

As described above, since the rental contract is scanned using OCR in the storage unit 310, the original contract is converted to grayscale, the binarization noise is removed, and the stamped area is detected through the contour detection and border connection processes. After that, it is connected and checked for matching with the result of extracting the outline of the painting at the bottom of FIG. 4b. To this end, the Canny contour detection algorithm can be used. A bidirectional filter that can well remove noise while preserving the contours is applied to threshold contour detection, and then the image is divided based on blocks, and then the gradient size of the image can be calculated for each block. there is. After that, the OTSU technique is applied to determine the high and low thresholds of the Canny operator, and the gradient size can be used in the image divided into blocks. The reason is to maximize the degree of separation between the object and the background, which is one of the important characteristics of the contour line to be known in detecting the contour line. Finally, we can use Canny's nonmax suppression to perform contour detection and concatenation.

The management fee collection unit 330, when the management fee is not deposited from the account of the lessee terminal 400 on a predetermined date, inputs the predetermined amount of the arrears fee and the management fee in a predetermined official document format and sends it to the lessee terminal 400. can At this time, the management fee collection unit 330 transmits information to the manager terminal 400 as well, so that it is possible to determine how many days the payment is overdue or overdue. Alternatively, it may be a terminal that generates a report every day and delivers it to a manager so that money can be collected.

The contract cancellation unit 340 transmits a contract expiration notice to the lessor terminal 100 six months before the expiration date of the lease period described in the lease contract, and the contract extension or contract termination action is selected from the lessor terminal 100 In this case, the lessor information and the lessee information included in the lease contract may be automatically input into an official document format previously mapped and stored for contract extension or contract termination, and may be transmitted to the lessee terminal 400 . Similarly, an official document format exists in advance for contract extension or contract termination, and as described above, it can be automatically entered into the agent and transmitted to the lessee terminal 400 . However, when a renewal request is received from the lessee terminal 400, the contract cancellation unit 340 transmits the renewal request to the lessor terminal 100 and prepares the documents as there are statutory reasons for rejecting the renewal request under the Commercial Lease Protection Act. can make it

The printing unit 350, when printing the official document generated by the official document management unit 315 at the lessor terminal 100 and sending it by mail, sends the A4 mail envelope and the generated official document to the lessee as the recipient and the lessor as the sender. You can control printing. In order to use the legal system of proof of contents, the landlord has to print it out, put it in a document envelope, and mail it at the post office. However, if the lessee, that is, the sender or the recipient is not properly written, it is arbitrarily returned and rewritten. Accordingly, the official document generated by the official document management unit 315 and the sender (lessor) and the recipient (lessee) are automatically inserted in the printing unit 350 into a postal envelope capable of containing A4, and the data is transmitted to the printer so that only paper is pasted. can Accordingly, the landlord can print the postal cover and certificate of contents simply by connecting the printer to his/her terminal or by simply sending a signal wirelessly if it is connected to the IoT, and the lessor can go to the post office and attach the mail to obtain the certificate of contents. The process of can be easily completed.

The reporting unit 360, when there are a plurality of lease contracts of the lessor terminal 100, manages by assigning an identification code to the plurality of lease contracts and generates a management report including the rent payment status, management fee payment status, and overdue status It can be transmitted to the lessor terminal 100. For example, if lessor A has 1 officetel in Gangnam, 2 officetels in Ichon-dong, and 3 officetels in Dogok-dong, how often and how much is the rent from multiple officetels or offices? It is not easy to figure out each contract date and expiration date. Accordingly, the current status of rent payment and the status of management support payment for each rental contract can be prepared as a report and transmitted to the lessor terminal 100, such as a report at the end of the month.

The smart contract unit 370 may store the contents of the contract based on the lease contract as a smart contract after the lease contract is uploaded. Smart contracts are Automated Self-Enforced Agreements, a concept that combines the two processes of contract establishment and execution into one through blockchain technology. The technical concept of a smart contract is a kind of program that automatically executes according to an event instructing the transfer of assets to the ledger while the transaction records are distributed and stored, decentralized and shared, and the replicated ledger is operated and stored. -Driven Program). Smart contracts are legally required to ① have two or more parties, ② relate to the transfer of assets from one party to the other, ③ implement automatically, and once the contract is initiated, It is a contractual concept that does not require human intervention. In this respect, a smart contract as a contract law element is a kind of algorithmic contract.

Smart contracts are executed automatically without human intervention, so they do not value the trust of the parties. Therefore, it is a kind of so-called conditional nature in which the problem of non-fulfillment of the contract, which is the biggest weakness of the contract, is not dependent on the credit of the other party but is determined by the fulfillment of programmed conditions. Therefore, in smart contracts, interpreting, judging, and evaluating whether conditions are fulfilled become a legally important issue, and conditions can be set based on third-party relationships as described above. Transactions in smart contracts are made in the order of ① programming code writing, ② code signing, ③ blockchain storage, and ④ transaction execution. The program code and the result executed here are included in the transaction and stored in the form of a database in a block connected by a chain, so that all participants share the transaction information, and the transaction details and contract details are distributed on the Distributed Ledger without addition or change. ) are stored independently of each other. Here, participants sign contracts and sign electronic signatures by linking the wallet address created by the public key encryption method with the blockchain. A smart contract transaction is a computer protocol designed to make it easy and convenient to execute or prove contract execution on a network, so the platform of the present invention, which requires evidence to be submitted when a dispute arises, will provide a clue to resolve the dispute. can

The brokerage request unit 380 rents based on the address, equilibrium, and options included in the rental agreement or the rental agreement when the rental property information is uploaded from the lessor terminal 100 or the lease term of the rental agreement expires and the contract is terminated. And a deposit may be calculated, and brokerage may be requested to at least one broker terminal 600 on condition of the calculated rent and deposit. At this time, if a 4-story building costs 1 billion, assuming that the 1st floor is 100, the rent can be calculated at a rate of 40 for the 2nd floor and 30 for the 3rd and 4th floors. In addition, the first floor corner is calculated as 120%, and the top floor with the sky lounge can be calculated as the second floor. And, the loan rate is 50% of the market price, and this amount is the All jeonse rate, and the deposit actually set is 20% of the Jeonse rate amount, and the remaining 80% is calculated as monthly rent. (Adjusted monthly rent multiplier of 60%) For a 10-year-old shopping mall, it can be said that 1.2 million won per month with a deposit of 50 million won for the first floor is appropriate. If you multiply the monthly rent of each floor by the monthly rent adjustment multiplier (general type 2: 0.6) and this amount is multiplied by the converted monthly rent multiplier of 100, it becomes the deposit conversion amount. In addition, since there is a key money in the case of a commercial building, the amount obtained by multiplying the sum of the deposit and the deposit conversion amount by 2 and then adding the key money can be the final market price reflecting the value. Of course, the above-described method is only one embodiment, and the price may be calculated by considering all other variables.

When a repair request or environmental claim is received from the tenant terminal 400, the life management unit 390 distributes the repair request or environmental claim to the previously registered manager terminal 500 so that the processing result is uploaded within a predetermined period. can Recently, as there have been many cases of managers committing suicide by exercising power or violence against managers, there is a growing awareness that not only should not use power against managers, but also that the intensity of work should be reduced or the environment should be improved. At this time, schedule management is an important means to complete the project within a given period. Determining activities and establishing and connecting them by establishing a precedence relationship is the most basic step of schedule management. To this end, the allocation problem of allocating n tasks to m managers may use, for example, the Hungarian Algorithm. This is an optimal solution algorithm that can solve the allocation problem in polynomial time, and assumes a situation in which there are many tasks and managers, and a situation in which the work time or cost of each task is different from that of a specific manager. It is a problem of allocating tasks to each manager in order to find an optimal solution that minimizes the sum of processing time and cost, assuming that a task must be performed by only one manager. This is called an assignment problem, and since it includes a balanced assignment problem and an unbalanced assignment problem, there are two cases of an assignment problem, balanced and unbalanced. As a method of solving the assignment problem, a Hungarian algorithm or a genetic algorithm can be used, but since there is a possibility that an optimal solution cannot be found for the imbalanced assignment problem, an imaginary row or column with all zero costs is added. It can be transformed into a balanced assignment problem. Of course, various algorithms may be used in addition to the above-described methods, and it will be apparent that the algorithms are not limited to those listed.

The tenant selection unit 391 stores at least one resident condition, and when a contract request is received from at least one broker terminal 600, the tenant information included in the contract request is compared with the at least one resident condition, and the degree of similarity is determined. After sorting in order, it can be transmitted to the lessor terminal 100. For example, if sex shops or massage parlors, which are harmful facilities for young people, enter a shopping district where academies are concentrated, the premium due to the formation of a cluster disappears and even the academies that have already moved in will be hit. Accordingly, when a rental property is issued, the lessor often determines the contract by limiting the type of business (use) or looking at the type of shopping mall to be entered, so the tenant selection government (391) It is possible to sort the tenants having similarities and transmit them to the lessor terminal 100. If the landlord sets the condition that all but this industry is possible, the information may be provided after removing the industry with the NOT operator and sorting in the order of the lessee with the highest rent.

Hereinafter, an operation process according to the configuration of the above-described official message sending service providing server of FIG. 2 will be described in detail with reference to FIGS. 3 and 4 as examples. However, it will be apparent that the embodiment is only any one of various embodiments of the present invention, and is not limited thereto.

Referring to Figure 3a, (a) the process of the lease contract has one cycle from signing the contract to paying the balance, receiving the brightness, paying the rent, and when the contract period expires, until the rental object is released to the brokerage office again. At this time, depending on the circumstances in which each event occurs, for example, when the lessee is in arrears or requests for renewal before the expiration of the contract period, but the landlord refuses to request renewal because he wants a store in a different industry to enter, each event exists. However, in consideration of such variables and the number of cases, the official letter sending service providing server 300 may first proceed with a database that stores each period and deadline and the format of the official letter according to the event or action of the lessor.

At this time, (b) when the lease contract is uploaded from the lessor and the lessee, integrity is checked by connecting each seal to see if they match, and then one cycle as in (a) is performed based on the contents of the lease contract. will make For example, if a contract is signed for 2 years from April 1, 2020, and the rent is to be paid on the 1st of each month, the period until March 31, 2022 is one cycle, and an event occurs on the 1st of each month. and confirmation), and six months before the expiration of the contract, that is, before October 1, 2019, the lessor terminal 100 asks whether or not to extend the contract, and the action of the lessor, that is, whether to extend or reject the renewal Accordingly, a process for sending an official renewal request or an official renewal refusal is created. Each deadline or period is statutory, so refer to it, but if laws or regulations are changed, the changed laws and regulations can be applied.

At this time, as shown in (a) of FIG. 3B, referring to FIGS. 4A and 4B, each blank exists and various information such as lessee information, landlord information, balance, rent, period, industry, etc. is described. The providing server 300 reads it through OCR, extracts data for each item, and stores the data. (b) If the rent is not paid on the rent payment date, an official document is created and transmitted to the lessee terminal 400, and (c) if the rent is overdue three times or more, the right to terminate the contract occurs, so whether to cancel it through the lessor terminal 100 Alternatively, an official document is prepared and transmitted to the lessee's terminal 400 by asking an action (lessor's decision) on whether to issue an overdue notice only. Also, (d) the server 300 for providing the official letter sending service may control the lessor terminal 100 to print the document since it is necessary to go to the post office and send the document in case of contents certification.
