Description

Real estate e-commerce system and method {Real estate e-commerce system and method }

The present invention synthesizes transaction elements selected from among each transaction element that forms a real estate transaction, selects a property using a listing score composed of the transaction element synthesis and graded listing, and contracts with the selected property online in real time by writing a contract and depositing a down payment. It relates to a real estate e-commerce system and method that automatically contracts.

Since real estate in real estate transactions is an immovable entity fixed to a specific location, a transaction broker usually guides the real estate on-site and provides related information.

However, with the emergence of electronic commerce by connecting to the Internet through a computer, it provides search for product information and even contracts. As a result, construction costs are reduced and convenience is achieved, so it is accepted as a revolutionary commerce.

Real estate transactions that follow this trend are also searching for listing information and transaction information on the Internet to save on construction.

As an example of related prior art that provides search for property information for real estate brokerage internet transactions as described above, Korean Patent No. 10-1865508 discloses a method of searching real estate-related information using a terminal, where the user searches Desired, first step of selecting period , second step of region selection, third step of selecting at least one real estate among the plurality of real estate included in the selected area, desired search among the plurality of areas of the selected at least one real estate The fourth step of selecting the area , the fifth step of displaying the first information related to the sale or lease of the first real estate corresponding to the selected area within the range selected above, and the sale of the second real estate that meets the selected conditions. Or a sixth step in which second information related to jeonse is displayed together with the first information, a seventh step in which the range of the gap investment amount, which is the difference between the real estate sale price and the real estate jeonse amount, is selected, the first real estate and the It further includes an eighth step in which third information related to the sale or lease of a third real estate within the range of the selected gap investment amount among the second real estate is displayed, and in the eighth step, the first real estate and the second real estate are displayed. A method for searching real estate-related information using a terminal is known, which is characterized in that the third real estate is determined using the average difference between the sales price and the lease amount of the most recent transaction month for each real estate .

However, since each transaction element that forms a real estate transaction, which is period, region, area, and gap investment amount, is selected one by one, properties are selected one by one, so in the conventional multiple-selection property selection, the properties in the first selection stage and the properties in several stages of selection are Although it is the same product, there is a problem with the prior art that the selection of the first transaction element grade, which is the property performance, cannot continue to maintain the grade depending on the selection of the property with only each transaction element grade being normal or below.

In addition, as an example of prior art related to selecting a real estate property and concluding a contract over the Internet, Korea Registered Patent No. 10-0728577 describes a direct, mechanical, and compulsory method of compulsory conclusion of an Internet real estate contract through the Internet without a direct human meeting. In this case, a person who has registered as a member of an Internet real estate transaction site by paying a deposit to enforce compliance with the site regulations may access the server (computer) that serves the site through the Internet on his or her PC (terminal) and Transaction conditions are divided into essential conditions (location, type, area, size, year of completion, land title, amount, delivery/acquisition time of real estate) and optional conditions (site registrant name, contact information, owner name, product video, and other matters). The first step is to register with the server; a second step in which the member accesses the server via the Internet on the PC to search and modify transaction conditions for registered items on the site; A third step in which the server searches for transaction conditions of real estate suppliers (sales/lease) and consumers (purchase/lease) stored in the database; A fourth step of mechanically and compulsorily concluding a site contract (private contract under civil law), which is the primary contract, on the server when there is a supplier and consumer whose transaction requirements match 100% as a result of a search for transaction conditions on the server; The details of the site contract concluded mechanically and compulsorily on the server are notified via the Internet to the real estate supplier and consumer, and to the selected real estate agency that will prepare a performance contract (brokerage contract according to the real estate brokerage business), which is a secondary contract that actually implements the site contract. The fifth step is to do; Regarding the results of signing a performance contract at the real estate agency for the actual performance of the site contract concluded on the server, the actual confirmed performance result is received from the selected brokerage and the relevant real estate information is deleted from the transaction list or posted on the site. Guaranteeing the actual truth of the person who has registered as a member for Internet transactions, receipt of a subscription deposit to enforce compliance with the site regulations, refund of the subscription deposit according to compliance with the regulations, collection of penalty for violation of the regulations, and the above site contract. A sixth step of managing the subscription deposit of paying the subscription deposit of a contract defaulter who did not actually perform the performance contract after conclusion as a contract penalty to the other party to the site contract; There is a known method of forcing a real estate contract to be concluded using a real estate agency on the Internet, which consists of:

However, the above-described prior art provides a direct, mechanical and compulsory method of compulsory conclusion of an Internet real estate contract through the Internet without a direct human meeting, but there is a problem in that the contract can be concluded mechanically and compulsorily.

As shown in Figure 1, when explaining the schematic diagram of the real estate e-commerce system 10 , a selling terminal 30 that provides real estate transactions online through the Internet and provides transaction items to the real estate e-commerce system, a real estate e-commerce system A purchase terminal (50) that purchases properties using a real estate e-commerce system, a financial institution server (60) that provides finance related to property transactions using the real estate e-commerce system, and rights and obligations related to properties corresponding to the real estate e-commerce system are performed in the register. It consists of a rough real estate e-commerce system through a registry office server (70) that performs real estate e-commerce system and a local government complaint server (80) that performs the rights and obligations related to properties for sale in each ledger.

Figure 2 is a block diagram showing a real estate e-commerce system according to the present invention.

In addition, as shown in FIG. 2, the system 10 includes a transaction element synthesis module 100, a property selection module 200, a property contract module 300, and a database 400.

The transaction element comprehensive module 100 has a purchase terminal that selects a property for sale, the transaction method is the Internet and can be done online, and there are each transaction element that brokers real estate transactions and forms a sale transaction, and in each transaction element The essential transaction element section 104 selected by the system 10 is composed of transaction elements as a group, and the transaction elements selected by the purchase terminal 50 as the discretionary transaction element 105 section are organized into groups, and each selected transaction element is organized into a group. It is composed by gathering together and synthesizing the same items in each transaction element at the same time.

Each of the above transaction elements is divided into the structure of the property or the function of the property transaction and may also include the property. Examples of each transaction element include use, contract type, price, transportation time, area, publicly announced land price, administrative district, and total floor level. , view area, contract period, rights analysis, mining, additional visual dimensions, school district, school, park, parking lot, road, convenience store, bus stop, subway station, railroad station, bus terminal, passenger ship terminal, elevation above sea level, electricity quantity, slope, lane road , building structure, earthquake prevention, security devices, safety devices, building residual value, population density, and building area of the district.

The listing selection module 200 generates the initial listing from the listings included in the transaction elements according to the transaction element rating setting of one of the transaction elements, and all created listings are created in conjunction with the transaction elements at the same time. In the listings, all listings are created according to the rating settings for each transaction element, and among them, the same listings that are common to all transaction elements are selected at the same time, each listing is selected based on the score of the selected identical listings, and the selected listings are finally searched. and is selected as the final item.

The property contract module 300 provides the property for which the seller subscribes online to the system and enters into a contract with the selected property according to the procedure of accepting the selection among the subscription products, and individually agreeing on the terms and conditions applied by the seller. A contract can be formed even without , and listed stock transactions can be seen as an example of this.

In such stock trading, the effect of the contract based on online subscription and acceptance is the same, and in this way, the property selection module 200 and the property contract module 300 clearly perform the contract process of the property selection and the entire property contract at the same time. It can be proven.

The database 400 is configured to input, output, and store real estate sale transaction data from each of the transaction element synthesis module, the property selection module, or the property contract module.

Figure 3 is a block diagram showing the transaction element integration module of the system according to the present invention of Figure 2.

In addition, as shown in FIG. 3, the transaction element synthesis module 100 includes each detailed transaction element (101 to 112), which is the listing grade order unit 101, satisfaction score unit 102, and essential transaction element unit 103. ), discretionary transaction elements section (104), upper transaction elements section (105), lower transaction elements section (106), special transaction elements section (107), additional visual dimensions section (108), total floor level section (109), view area It includes a unit 110 and a mining area unit 111.

The listing rating order book 101 simultaneously ranks the number and presence of each transaction element item, for example, the low price is first, the low transportation time is first, and the wide area is first. As for the floor, the higher value is first place, and the above-mentioned listing values are displayed in first place order, while in the same direction, they are displayed in lower order, which is unreasonable. Therefore, at the same time, each transaction element is displayed in first place order in one direction. It is also visually unified.

The satisfaction score unit 102 determines as a satisfaction score the absolute value subtracted from the value of each graded item in the order of each grade of the transaction element by the value of the highest graded item or the minimum graded item, and each identical item of each transaction element. It consists of a satisfaction score that is the sum of the satisfaction scores.

Accordingly, from each grade value according to the order of each listing grade for each transaction element, the absolute value of each value subtracted from the maximum grade value or the minimum grade value is created as a satisfaction score. Specifically, the satisfaction score is unified with more scores being more satisfactory. For example, in a situation where a lower price is better and a lower transportation time is better, on the other hand, for the same price, a wider area is better, and the view is better as the view area is wider, it becomes a satisfaction score that unifies these conflicting standards into one.

As a result, each of the same items is in each transaction element, an absolute value is calculated according to the value of each transaction element grade, and this absolute value becomes the satisfaction score, and a satisfaction score for each transaction element is generated and thus the same A satisfaction score is created for each listing, and the satisfaction scores for each transaction element for the same listing are added up to create a satisfaction score for one listing, allowing each listing to be selected accordingly.

Accordingly, the satisfaction score unit 102 suggests calculating the satisfaction score according to the absolute value of the sale in Table 1 (transaction element listing table), and each transaction of each sale in Table 2 (satisfaction score sum table). Sum up the satisfaction scores obtained from the elements.

As such an example, each transaction element is created interlocked according to the synthesis of each transaction element, and accordingly, there are 10 transaction elements from p and a to i, and each transaction element has ① each item for sale. There are 5 items for sale from ⑤ items for sale, and specifically, there are 5 items for sale at price p (transaction element), and below are the transactions for each of a, b, c, d, e, f, g, h, and i. There are 5 items for sale in the element, and in each transaction element from p and a to i, there are 10 identical items for ① each, and hereinafter, each transaction element contains 10 items from ① the same item to ⑤ the same item. Each listing is selected using a score that is the sum of the scores of each identical listing, and as a result, 10 identical listing scores in each transaction element from p and a to i are generated.

Table 2 (Satisfaction Score Total Table)

In Table 2 above, the scores of the five listings are selected as each satisfaction score for each listing from nine transaction elements from transaction element A to transaction element I, and therefore, according to the sum of the satisfaction scores of each transaction element, ① the satisfaction score for the listing is It is 45 points, ② the satisfaction score for the listing is 39 points, ③ the satisfaction score for the listing is 23 points, ④ the satisfaction score for the listing is 11 points, and the satisfaction score for ⑤ the listing is 2 points.

Looking at the relationships between the essential transaction elements unit 103 , the voluntary transaction elements unit 104 , the upper transaction elements unit 105 , the lower transaction elements unit 106 , and the special transaction elements unit 107 , Each of the above divisions consists of each transaction element of each division into groups, and each transaction element of each group is structured as follows.

The essential transaction elements section 103 indicates the type of use for each transaction element , the contract type indicates sales and leases contracted through rights and obligations, the price indicates the transaction price, and the contract type indicates the transaction price . The transportation time is indicated by the time or distance related to the transportation used, the area indicates the area used, the administrative district indicates the regional location, the publicly announced land price indicates the price per unit area of the publicly announced standard land, and the above floor The total floor indicates the floor and total floor of the building, the view area indicates the view in terms of area, and the rights analysis includes each transaction element that confirms the truth of the rights relationship of the property, and properties for sale with these essential transaction elements are required to be selected. It is composed of

The random transaction element unit 104 is configured to randomly select each transaction element from the provided transaction elements and to select the items for sale of the randomly selected transaction elements.

The upper transaction element unit 105 is a relationship between each transaction element of the required transaction element unit or the discretionary transaction element unit, and there is no other transaction element at the upper level, there is or is no other transaction element at the level, and there is another transaction element at the lower level. There is or is not, and the number of items created from each lower transaction element is configured to be created in the upper transaction element.

The lower transaction element unit 106 is a relationship between each transaction element of the required transaction element unit or the optional transaction element unit, and there is another transaction element at the upper level, there is another transaction element at the same level or there is no other transaction element, and there is another transaction element at the lower level. There is or is not, and the number of items created from each lower transaction element is configured to be created in the upper transaction element.

The special transaction element section 107 selects each transaction element again from each transaction element that has already been selected from each transaction element of the required transaction element section 103 and the discretionary transaction element section 104, and selects them again. As a standard, each transaction element that equalizes the importance of the transaction elements is selected, and the selected transaction element items are selected with priority.

In the selection of each transaction element as more important, the importance of each transaction element is equalized as described above, and the importance of each transaction element in the mandatory transaction element section has already been objectively selected, and the importance of each transaction element in the discretionary transaction element section has already been objectively selected. The importance has already been subjectively selected, but the purchasing terminal itself searches and selects subjectively more important transaction elements from the already selected objective and subjective transaction elements, and each selected transaction element is equally selected to the extent that there is no difference between them. In this way, the transaction elements for which the purchase terminal is selected as the core are configured so that no weighting is necessary. For example, the purchase terminal is configured to prioritize the child's school district and select the transaction item as the top priority, hereinafter price, transportation time, and area. , outlook, etc., can be composed of various transaction elements.

As described above, the scores of the same items in each transaction element are summed so that the item selection in the selected transaction elements is the score, and the items are selected based on the scores of each identical item. If there is a difference in importance in these score sums, the points are summed. Errors occur and trust in product selection is lost, so the above-mentioned importance is important.

It is difficult to correct the importance of each transaction element in such a short period of time online, so the above-mentioned system of online e-commerce is selected without weighting.

Afterwards, the selected item is not weighted even if the item is selected from each other transaction element, and is selected so that no weight is given to the total score of each transaction element as described above.

As another example, the special transaction element unit 107 may select a transaction element whose importance is equally equal in each transaction element without re-selecting each transaction element of the required transaction elements and optional transaction elements. .

As another example, in setting the weight for each transaction element of the essential transaction element section and the discretionary transaction element section in the special transaction element section 107 , the subjectivity of the purchase terminal of the above-mentioned importance is excluded and each transaction element is subjectivity to objectivity. It can be configured to judge, and subjectivity can be selected by objectifying that, for example, depending on age, school districts are needed or trails are important transaction factors at an age that requires health.

The additional visual dimension unit 108 has a visual dimension that calculates the so-called visible size as the exclusive area when calculating the exclusive area, and an invisible area that occupies half of the wall thickness when calculating another exclusive area. There is a center line dimension that is calculated as the exclusive area including the size, and this result shows that the numerical value of the exclusive area on the register is the same, but the difference is that the exclusive area of the eye dimension and the exclusive area of the center line dimension are different by the half area of the wall thickness actually included. Even if the register cannot be modified to unify this situation, it is configured to convert it to the center line size and record it based on the eye size in property transactions.

The total floor section 109 divides the floor locations of the property into each range in height order, divides the total floors of the property into each range in height order, and divides the total floors of the property into each range in height order. The highest floors of each building are divided into each range in order of height, and are created as common items according to the range settings for each transaction element.

The above floors are all calculated in height order in each building, divided into each range in height order, and each corresponding range is selected. For example, each range is divided into 5 parts, and all of the 5 parts correspond to the 1st part of each range. Listings for the corresponding floor of each building are created.

For the total floors, all floors of each building are divided into ranges in order of height, and each corresponding range is selected. For example, each range is divided into 5 parts, and all buildings corresponding to the 1st part of the 5 parts are divided into 5 parts. Properties for that floor are created on all floors.

The highest floors of each building are divided into ranges in order of height, and each corresponding range is selected. For example, each range is divided into 5 parts, and each range corresponding to the 1st part of the 5 parts is divided into 5 parts. Listings for that floor are created on each top floor of the building.

Among the listings created in the floor, the listings created in the total floor, and the listings created in the highest floor, common listings are created.

First, items for sale are selected from each of the selected floor, total floor, and highest floor, and then, since the floor, which is a transaction element selected from among these three transaction elements, is closer than other transaction elements, the property is selected as a layer.

The view area unit 110 needs to measure the view area by dividing the view into areas so that the view can be traded, and this area is set as a square area in the center and a fan-shaped area on the left and right, The view area is made up of the sum of each area.

The view area portion 111 is a rectangular area created with a vertical length that blocks the straight-line view from the horizontal length of the window and the horizontal starting point, and the fan-shaped area is within 90 degrees of the vertical side and vertex of the horizontal starting point of the window. A fan-shaped area, which is an arc on the other side of , is created on the left and right sides of the square, and the square is created in plurality according to the blockage of the vertical length. A plurality is created, and it is composed of a view area that sums up each of the above areas.

As another example, in the view area unit 111 , in addition to the view area, it is possible to select the area of each transaction element divided and divided, including mountains, rivers, seas, grasslands, parks, city buildings, roads, etc. It can be configured.

As another example, the view may be a view volume, and the volume may be created at a high location and configured to evaluate the fullness of the view.

As another example, the fan shape may be more specifically composed of the area of a triangle consisting of the height of the triangle at the vertex and the base corresponding to the arc.

It is difficult to indicate how much the mining area is per day in the mining area unit 111 , because the mining area fluctuates, so it is difficult to select a certain time, so the time of the mining area is divided into seconds, minutes, and hours. Because it is difficult to measure the mining area as a unit and compare properties, it is divided into several parts and made into units, and the mining area for a day is secured by dividing it into the mining area within a certain time and adding it up, for example, 10 minutes. If it is divided into one unit, it is divided into the number of mining hours per day, the mining area is measured in 10-minute increments, the mining area for the day is totaled, the total mining area is divided by the number of mining hours, and each mining area is divided by the mining time unit. It consists of evaluating the property.

Figure 4 is a block diagram showing the property selection module of the system according to the present invention of Figure 2.

In addition, as shown in FIG. 4, the listing selection module 200 includes each detailed transaction element (201 to 210), a comprehensive selection display unit 201, a selection result display unit 202, an initial listing creation unit 203, Initial listing execution unit (204), special listing selection unit (205), required listing selection unit (206), cost-effective listing selection unit (207), final listing search unit (208), document listing search unit (209), video Includes a property search unit 210.

The comprehensive selection display unit 201 is displayed as an indicator that synthesizes the grades and listings of each transaction element, and changes all transaction elements at the same time in the repetition of the created items according to the setting of each transaction element grade, or changes a specific transaction element among them. is displayed so that it can be fixed, and is displayed as a common offering in each transaction element grade and a synthesis of the listings, and is configured to be displayed when there is no common offering in each transaction element grade setting.

In the general selection display unit 201 , visually through Table 3, each transaction element and the grade and sale of the transaction element are simultaneously synthesized and displayed, and at the same time, the number of items generated according to each grade setting of each transaction element and In the rating range display, the range is adjusted from a black indicator to a white indicator depending on the selection of each range, the range of grades common to each transaction element grade and property listed above is displayed, and each transaction element grade is set. When there are no products for sale, it is displayed by sound or sight.

Table 3

In Table 3 above, you can see the entire transaction element synthesis at the same time, and you can also see the common parts in the creation of each transaction element grade item in the transaction element synthesis, and the common parts for each transaction element grade 9 to 12 presented by the indicator above. This results in the selection of a property.

In Table 3, the product range created according to each rating setting for each transaction element is repeated at the same time, and changes in this repetition are searched, and changes in specific transaction elements are searched as fixed. These results are displayed at the same time from all transaction elements. You can choose the item for sale, but the transaction elements selected by the buying terminal are essential, and the rest is structured so that you can select a certain level of difference in rating.

In Table 3, each transaction element grade setting and the products created accordingly are viewed as a comprehensive selection display unit 201, and the items created according to the transaction element grade settings are all repeatedly selected at the same time and common items are selected. You can choose.

In this way, in order to select a property from each transaction element of the above-mentioned transaction element comprehensive, for example, a property is created according to the price grade setting and linked to each transaction element grade, and when a view is selected from the property created here, the transaction element grade of the view is It is set, the item is selected, created, and the re-created item is created in conjunction with each transaction element grade. Each transaction element grade is set one by one, the item is created, and at the same time, all items are selected through linked creation as transaction elements. .

As another example, the general selection display unit 201 may provide selection of an item for sale as a result of calculation without visual indication or calculation process in the common part selection of Table 3.

In Table 4, the selection result display unit 202 displays the listing selection process as start and change, and the start and change are divided into the number of listings, the number of buying terminals, the number of one-to-one pairs established, and the pair establishment without change in the number of listings. It is configured to display including the number of terminals purchased and withdrawn, and can be explained in detail in Table 4.

Table 4

At the beginning of Table 4, the number of items is the number of items initially selected, the number of buying terminals is the number of buying terminals that perform the item selection, and the number of one-to-one pair establishment is the number of buying terminals that selects the item. The number of selected results is displayed and the start is 0, and the number of pairs established without change in the number of items indicates that each buying terminal selected an item other than the first selected item out of the common number of buying terminals and a pair was established. The start is 0, and the number of withdrawal purchase terminals indicates the number of purchase terminals that withdraw due to establishment or failure in the property selection process, and the start is configured to display 0.

Afterwards, in the change in Table 4, the number of items is the number of items according to the selection, the number of buying terminals is the number of buying terminals executing the item selection, and the number of one-to-one pair establishment is the number of buying terminals. The number of results of selecting a product is displayed, and the change is the corresponding number, and the number of pairs established without change in the number of items is the pair established by each buying terminal selecting an item other than the first selected item from among the common number of buying terminals. It indicates that it has been established, and the change is the corresponding number, and the number of withdrawal purchase terminals indicates the number of purchase terminals that withdraw due to establishment or non-establishment in the item selection process, and the change indicates the corresponding number.

Each transaction element is selected from each of the initial listing creation unit 203 , the special listing selection unit 205 , and the mandatory listing selection unit 206, and each selected transaction element is given a rating. According to this one transaction element rating setting, an item is created, and all created items are created in conjunction with each transaction element at the same time, and the item is selected by repeating the same rating setting.

In an embodiment of the present invention, when the number of items for sale in each part is expressed as at least one or more and when it is expressed as a number of at least two or more, the competition for the number of items for sale must be assumed to be plural, but even for one item, each item must be The present invention can be evaluated and selected based on transaction factors, and since the present invention selects items for sale according to a comprehensive combination of transaction factors, it is expressed as including one item for sale, and is also different from the conventional item selection in which items for sale are selected one by one.

Each of the above units divides each transaction element, and each transaction element composition arbitrarily determines the initial listing creation unit 203 , the composition of each transaction element arbitrarily determines the special listing selection unit 205, and the mandatory listing selection unit 206. Each transaction element can be configured to arbitrarily determine the purpose, and the special transaction element department, essential transaction element department, and voluntary transaction element department can be changed to different names.

Each of the transaction elements provided or selected herein may be made common as a whole or as a part thereof, and each of the transaction element classes may be made common as a whole or as a part at the same time. The transaction element grade is configured so that all items can be selected simultaneously, either as a whole or as individual parts.

The common is applied simultaneously to each of the initial listing creation unit 203 , the special listing selection unit 205 , and the mandatory listing selection unit 206 , and this common application is applied to each transaction element class. In terms of the range, for example, the rating range from 1 to 5 can be common, and like the rating range of each transaction element, it is configured to be a common product when the product is the same product.

For example, select a property for which the price grade range setting, area, publicly announced land price, and administrative district grade range are all common at the same time, and the grade range setting for transportation time, school commuting time, walking distance, and library distance are all common at the same time. It is configured to select an item for sale, and select the item for sale in common at the same time as a whole, setting the rating range and selection of each of the selected transaction elements.

The initial listing creation unit 203 generates an offering according to the rating setting of one of the transaction elements in at least one transaction element of the comprehensive transaction elements of the special transaction element unit 107 and the essential transaction element unit 103. The generated items are created in conjunction with each transaction element at the same time, are created as each identical item according to a common range setting for each transaction element grade range at the same time, and the generated identical item is created as an initial item.

The synthesis of each transaction element in the special transaction element department 107 and the essential transaction element division 103 brings together each transaction element and simultaneously synthesizes each transaction element and the sale, and this synthesis is performed sequentially and individually for each transaction element class. It is designed to prevent property selection.

Accordingly, one of each transaction element is selected and one is selected. For example, the above price is selected, an item is created according to the rating setting, and all created items are created in each transaction element at the same time.

The range of each transaction element grade of the created product is simultaneously searched through the comprehensive display unit 201, the same product is created according to a common range setting, and each of the generated identical products is designated as an initial product. do.

As another example, the initial item creation unit 203 may select each transaction element arbitrarily without selecting each part of the special transaction element unit 108 and the essential transaction element unit 103.

As another example, in the initial listing creation unit 203, the range of each transaction element grade in the comprehensive selection display unit 201 is set as a standard and comprehensively selected for listing and calculated without displaying the comprehensive selection display unit 201 on the screen. It can be configured to select options according to each transaction element and common and identical items among them.

The initial listing execution unit 204 sums the number of purchasing terminals that have set the number of initial listings and the number of other purchasing terminals that have already set at least one or more of the number of initial listings, and sets an initial listing number greater than the total number of purchasing terminals. If the number of items is equal to or exceeds the number, it is executed as an initial item. If the number of items is less than the total number of purchase terminals, it is terminated or reserved as an initial item, and then received and executed as an initial item.

In the case of property selection without management as described above, an uncertain situation arises where selection is difficult, or property selection may be repeated, and due to this uncertainty, property selection is given up, resulting in inconvenience in the purchase terminal's property selection, economic damage, and the above. To prevent trust from falling in the system, property selection is managed through the number of purchase terminals and the initial number of properties.

In addition, in the initial listing execution unit 204 , in the selection of purchase terminals and initial listings in which the standards of the previous purchase terminal and the standards of subsequent purchase terminals change, the number of initial listings and purchase terminals after the transfer is determined according to the selection of the listing. Selection is also comprised of conditions for selecting a property.

The special item selection unit 205 generates each transaction element grade by inputting the initial item into at least one transaction element of the transaction element synthesis of the special transaction element unit 107, and sets each transaction element grade. At the same time, identical items that are common to all are created, and each absolute value subtracted from each identical item value by the maximum or minimum rating value for each transaction element rating order of the generated identical item is generated as a satisfaction score. It consists of selecting the same item based on the given satisfaction score.

In the special listing selection unit 205 , each transaction element synthesis of the special transaction element unit 107 gathers each transaction element together to synthesize and simultaneously select each transaction element and item, and this transaction element synthesis is individually It is configured to prevent sequential selection of each transaction element item.

Through the satisfaction score unit 102, each absolute value is generated by subtracting the maximum or minimum grade value from each grade value of each grade order of each transaction element of the selected item, and the absolute value generated here is set as the satisfaction score, The satisfaction scores of each identical product in each transaction element are added together to select the product based on the product satisfaction score.

In this satisfaction score sum, the results according to the sum are used and are constructed reliably using only each transaction element whose importance according to the sum of the satisfaction scores of the sale is equally selected through the special transaction element unit 107.

The mandatory item selection unit 206 generates each transaction element grade according to the selected items in each transaction element of at least one transaction element of the mandatory transaction element unit 103 and the discretionary transaction element unit 104, Each transaction element grade is set, and at the same time, identical items that are common to all are created, and each absolute value subtracted from each identical item value by the maximum or minimum grade value is satisfied for each transaction element grade order of the created identical item. It is generated as a score, and is configured to select the same item based on the generated satisfaction score.

In the mandatory item selection unit 206, each transaction element synthesis of the required transaction element unit 103 and the optional transaction element unit 104 is performed by gathering each transaction element together to synthesize and simultaneously select each transaction element and item. , this synthesis is designed to prevent selecting each transaction element item individually and sequentially.

Through the satisfaction score unit 102, each absolute value is generated by subtracting the maximum or minimum grade value from each grade value of each grade order of each transaction element of the selected item, and the absolute value generated here is set as the satisfaction score, The satisfaction scores of each identical product in each transaction element are added together to select the product based on the product satisfaction score.

In the sum of the satisfaction scores, since the importance according to the sum has already been selected according to the selection of each transaction element with equal importance through the special property selection unit 205 , the importance and importance have already been selected through the mandatory property selection unit 206. Regardless, the item for sale is selected based on the sum of the satisfaction scores.

The cost-effective listing selection unit 207 divides the listing price into a satisfaction score that is the listing performance, and the satisfaction score of the listing is determined by the satisfaction score generated by the special listing selection unit 205 or by selecting the required listing. The satisfaction score generated by unit 206 or the sum of the satisfaction scores of the special property selection section and the mandatory property selection section is used, and the cost-effectiveness ratio of each property is displayed in rank order and the first-place final product is selected. It is composed of

In the display of listings in the above cost-effectiveness grade order, in Table 5 above, the grades are indicated as 1st grade, 2nd grade, 3rd grade, 4th grade, and lower grades, and the number of listings is one or more of the number of listings corresponding to each grade. The number of purchase terminals corresponding to each grade and number of items for sale is displayed to confirm what content has been selected.

Table 5 (Cost-effectiveness rating order table)

Selecting the item with the highest cost-effectiveness means selecting the item grade order in Table 5 above. If there is one item ranked first in the above confirmation and the purchasing terminal can select it, it can be selected, and if another terminal has already selected it, it can be selected in second place, Since you are selecting the initial listing that can be selected in the order of 3rd place, etc., the contents of the selection are explained.

As another example, the satisfaction score of the above-mentioned listing is composed of the special listing selection unit 205 or the mandatory listing selection unit 206, or each transaction element of the special listing selection unit and the mandatory listing selection unit, but a group Rather than composing each part separately, the satisfaction score can be composed directly of each other transaction element.

The final listing search unit 208 selects at least one transaction element from the plurality of final listings, and the plurality of order selections include the special listing selection unit 205 or the required listing selection unit 206. Then, a single final product is selected based on the sum of the satisfaction scores of each of the selected transaction element products, and the single final product is requested to be searched with priority within a certain period of time and consent is received.

As another example, it is configured to send an alarm that ends when the search time for a property approaches a certain time.

The document listing search unit 209 displays the value or presence or absence of each transaction element itself in each transaction element of the special listing selection unit or mandatory listing selection unit that selects the final listing, and determines the satisfaction of the final listing of each transaction element.
