Abstract

An optimum auction method using a network is disclosed. Especially, being different from a typical auction method for simply evaluating a personally proposed bod price, the optimum auction method evaluates various evaluation particulars for the auction and evaluation methods in overall, thereby selecting an optimum bidder who is close to an intention or taste of an auction initiator or able to maximize a profit even though the selected optimum bidder does not propose the highest or the lowest bid price. Accordingly, it is also possible to broaden a range of participation and improve efficiency on the auction. Also, there are various types of the optimum auction method including a reverse auction, a lease auction and a reverse lease auction which can proceed with various trading methods by maximizing the profit of the auction initiator.

Description

Optimal Auction Method Using Web Services

technical field

The present invention relates to an optimal auction method realized by using a web service, and more specifically, to a method by diversifying evaluation items and evaluation methods of an auction and evaluating the diversified evaluation items and methods, instead of Evaluate only the prices proposed by individuals to select as the successful bidder the one participant that is closest to the auction sponsor's intentions or preferences or that maximizes the auction sponsor's profit, even if the selected participant is not the highest bidder or the lowest bidder and an optimal auction method, which can use communication networks such as the Internet to maximize the profit of the auction initiator through various types of auctions such as reverse auctions, lease auctions, and reverse lease auctions.

Background technique

Auctions are divided into seller's auction and buyer's auction, both collectively referred to as auction. In some cases, a seller's auction is called an "auction" and a buyer's auction is called a "reverse auction." Also, "to rent out" means to make a profit by leasing the property of the lessor to a lessee, while "to lease" means to pay a sum of money to use the property of the owner. Often, the two terms are collectively referred to as "lease" or "item hire", without distinction.

In various auctions, the most important fact is to maximize the profit of the auction initiator, which is the purpose of the auction. So, in a seller's auction, the highest bidder will be the successful bidder, while in a buyer's auction, the lowest bidder will be the successful bidder. However, in a general auction or reverse auction, the highest or lowest successful bidder is usually selected from among many participants simply by comparing the prices proposed by the participants. Therefore, through this selection method, the profit maximization of the auction initiator will be limited, and the participation range of the auction will be unnecessarily limited, thereby reducing the efficiency of the auction.

According to the selection method usually adopted in general auctions, even if a certain bidder offers a better choice or additional conditions, if the bidder proposes a lower price, the bidder is not allowed to be selected. As a result, sellers lose the opportunity to gain additional advantages other than price, and those bidders who can offer better options or terms are reluctant to participate in the auction. As a result, majority competition may not be achieved, thereby reducing the efficiency of the auction. Especially for rental auctions, there may be situations where many bidders can be combined on a certain rental schedule. However, the general auction selection method only evaluates the prices proposed by individual bidders, and selects the bidder who proposes a higher price, even if a certain group of bidders proposes better conditions. Therefore, there may be a problem that the lessor cannot maximize the profit.

Contents of the invention

An object of the present invention is to provide an optimal auction method realized by using a network such as the Internet, in which a system for providing an auction service for trading items between participants is constructed.

Another object of the present invention is to provide an optimal reverse auction method in which the person who initiates the auction is reversed from the general auction method.

Yet another object of the present invention is to provide an optimal reverse auction method in which those who pay the bids are the opposite of normal auction methods.

Yet another object of the present invention is to provide an optimal reverse auction in which the person who initiates the auction is reversed and the person who pays the bid is reversed from the normal auction method.

According to an aspect of the present invention, an optimal auction method using a network is provided.

Although the item to be auctioned by the auction initiator of the reverse auction can be a designated unique item, such as a specific product of a certain company, any item can be auctioned as long as the basic requirements are met. Also, certain items that most auction sponsors define are not so important that they need not be considered as basic requirements, but they cannot be ignored, so they should be properly evaluated. That is, these matters should be reflected in the evaluation of the auction to maximize the auction sponsor's profit or to bring these matters closer to the auction sponsor's intentions or preferences. For example, if the auction sponsor prefers a window seat, while a window seat could be set as one of the basic requirements, this preference can be applied as an evaluation The person who proposes a window seat is selected as the successful bidder, even though a window seat is more expensive than an aisle seat. If choosing a window seat is financially burdensome, a price evaluation item may also be set so that the person who proposes the aisle seat is selected as the successful bidder.

Therefore, when conducting a reverse auction, first set the basic requirements, and set those things that need to be evaluated and the bids. Then, assign reference scores and grades to bids and items, and proceed to auction transactions. Thereby, the overall evaluation of the proposals of the auction participants enables the bidder who can maximize the profit of the auction initiator or is close to the intention or preference of the auction initiator to be selected as the optimal bidder. In the present invention, the auction initiator can set evaluation items arbitrarily, and can only set one evaluation item, or can set multiple evaluation items.

Since the above-mentioned auction transaction sets the basic requirements that are essential to realize the auction transaction, there are fewer restrictions on participation in the auction, and even if a participant is at a disadvantage in terms of bidding, there are matters that make it superior to other participants, Fair valuations can also be achieved, thereby providing a fair deal and increasing the number of people attending the auction.

If it is an item rental auction, an additional evaluation method can be supplemented on the basis of the above-mentioned auction transaction method to maximize the profit of the auction initiator. Among the participants, for each case, group those participants who are suitable for co-renting the item according to the item-renting schedule, and between selected individuals and the combined group, or within a combined A comparative evaluation is performed between a group and another combined group to select individuals or individuals who can maximize the auction initiator's profit or have the best conditions to meet the preset evaluation criteria (for example, a certain preference of the auction initiator). Group.

In addition to bids, item rentals include other variables, such as rental schedules. Each person applying to rent an item may have a different or the same desired rental period, and in some cases certain dates of the desired rental periods of the individuals overlap. In this case, the general auction method cannot effectively select the optimal bidder and maximize the profit, because in addition to bids, the expected date and lease period applied by the auction participants are compared with each other.

For reference, common methods of renting items are implemented based on preset rental periods and bids. Even in the case of such item-hire auctions, implementation is very limited.

For example, according to a common method of item rental, the unit period of item rental is set to be short-term, such as one day and two days, and prices proposed for one day and two days are compared with each other to select the highest bidder. However, in this common method of item rental, only those who want to rent the item for a short period of time participate in the auction. Therefore, it may be difficult to attract participation and competition among those who want to rent items for a long term, thereby reducing the efficiency of the auction. The reason for this low participation and competition rate is that there is no guarantee that those who want to rent an item for a long time will get the next rental contract in a row.

For example, if someone is renting a bag for a 7-day trip, it's useless to get a contract for the first 3 days and a contract for the last 2 days, because there are two days in between without getting a contract. Therefore, both actual transactions and people participating in the auction are limited, and it is very inconvenient to apply for long-term rental because the period of the auction is short-term. Moreover, due to the high number of short-term auctions, distribution costs such as handover costs increase, thereby reducing the realism of transactions.

Even if the unit period of item rental is extended by about one week, about 10 days and about one month, the same problem still occurs. Those renting for a shorter period than those units would not participate in the auction, as costs would increase unnecessarily. Therefore, it is difficult for this auction transaction to attract participation and competition among those who apply for short-term rental items, and as a result, the range of participants who apply for the auction is limited, thereby reducing the effectiveness of the auction.

In order to solve the above problems, the auction transaction should be implemented without setting the unit period, and for the case of exceeding the preset unit period, it is necessary to allow the applicant to rent for as long as necessary. However, this common auction method can cause another problem.

Another problem with this common auction method is evaluating unit prices and bidders' bids.

For example, suppose there are three people who want to rent an item for 7 days, 4 days, and 2 days. If the person who bids for 7 days and the person who bids for 4 days offer the same price, you need to determine who has priority. According to the daily average unit price, the person who bids for 4 days will be the best bidder. However, based on the total price, those who bid for 7 days offered the highest price, and based on the average unit price, those who bid for 4 days provided the highest price. Therefore, it is necessary to set up detailed evaluation items and procedures to determine and select optimal conditions.

If the lease terms used by the three people overlap with each other, it is necessary to determine and set the priority of evaluating whether the total price or the average unit price is evaluated in advance, or evaluate both the total price and the average unit price. With this presetting, desired transactions can be easily realized. However, an additional process must be provided that is different from the usual auction transaction method to enable this type of auction transaction. That is, the evaluation method is set as the process of applying evaluation based on total price or average unit price and determining evaluation priority.

However, if the lease terms used by the three persons partially overlap or do not completely overlap, using the above method is not sufficient to achieve an auction transaction. Therefore, additional evaluation benchmarks and decision methods need to be set. That said, someone who rents for 7 days may not be offering the best terms, even if they decide to prioritize the total price when evaluating. And, if it is possible to split the schedule of the person who rented for 7 days and assign the split schedule to the person who rented for 4 days and the person who rented for 2 days without interfering with each person's schedule, the total price of the above schedule It is the result of adding the person who rented for 4 days and the person who rented for 2 days, which is greater than the person who rented for 7 days.

In this case, the auction initiator can maximize profits when combining several participants, even if each participant bids lower than in an auction in which each participant submits a higher bid.

Therefore, in the case of item rental auctions, the usual auction method of only evaluating the prices proposed by the various participants is difficult to achieve transactions. For this reason, in order to select the best bidder (which can be an individual or a combined group), in addition to comparing each individual, it is necessary to compare each individual with a group of multiple individuals, or to compare the bidders of a combination Group is compared to another combined group. Also, instead of just evaluating the total or unit price, an overall evaluation method is needed that determines the optimal conditions for auction transactions by examining the adopted schedule and total price as a whole, and then evaluating the types of transactions that may be combined.

In summary, according to the preferred embodiment of the present invention, the optimal auction method using the network includes a series of processes performed sequentially in order to select the optimal bidder. First, an auction transaction intermediary server is provided with an intermediary system capable of selecting an optimal bidder by analyzing proposals of auction participants and overall evaluating these proposals according to auction conditions and evaluation methods set by an auction initiator. The auction initiator enters the characteristics, basic requirements and evaluation methods of the items to be auctioned, including evaluation items and evaluation criteria, and then, auction participants apply for bidding through a predetermined auction process. Subsequently, auction participants are evaluated overall according to the optimal auction process built in the intermediary system to select the optimal bidder that is closest to the auction initiator's desired conditions and maximizes the auction initiator's profit. Once an auction transaction is confirmed, the auction item is delivered to the selected best bidder by direct or indirect means, such as a courier or postal service, and the bid is paid to the auction initiator.

According to the proposed optimal auction method, auction initiators and auction participants can use communication networks to trade desired auction items in various auction transaction types without limitation. Because the optimal auction method selects the bidder closest to the auction initiator's intention or able to maximize the profit, the maximum profit of the auction initiator can be achieved. Also, due to this characteristic of the optimal auction method, it is possible to expand the participation of those interested in the auction and to improve the efficiency of the auction through various competitions.

Detailed ways

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a diagram briefly illustrating a system configuration to which an auction transaction method using a network is applied according to the present invention.

As shown in the figure, the system includes: a first terminal 100 of an auction initiator; a second terminal 200 of an auction participant; an auction transaction intermediary server 400; a communication network 300 such as the Internet; an insurance institution 500;

In the present invention, the auction transaction intermediary server 400 analyzes auction conditions of items to be traded among persons related to the auction and generally evaluates conditions proposed by auction participants to select participants who propose optimal conditions. After selecting the best participants, a contract note is created. Next, download the transaction note to the first terminal 100 and the second terminal 200, and invite the auction initiator and selected auction participants to draft contract terms. In the present invention, although the transaction can be performed using the contract note as described above, the decision of the transaction item is sufficient even without drafting a contract.

Referring to Fig. 2, the auction transaction intermediary server 400 includes: an interface unit 401; a control unit 402, which is a central processing unit; a contractor information analysis unit 403; a transaction document detection unit 404; a verification unit 405; an encryption processing unit 406; ; transaction document database (DB) 408 ; contract-related information database 409 ; member-related information database 410 . Other types of databases can be added as needed.

In the present invention, the interface unit 401 serves as an interface between the auction transaction intermediary server 400 and the communication network 300 . The contractor information analysis unit 403 analyzes information provided from the first terminal 100 and/or the second terminal 200 and detects a corresponding auction type and a category of an auctioned target item. Among the various forms of contract notes stored in the contract note database 408, the contract note detection unit 404 detects the contract and the transaction type between the auction initiator's first terminal 100 and the auction participant's second terminal 200 and the transaction type. The contract note of the item, and according to the analysis result of the contractor information analysis unit 403, many items are added to the detected contract note.

In addition, the verification unit 405 also verifies whether the transaction note created by the transaction note detection unit 404 is normal. At the same time, the verification unit 405 requests the auction initiator of the first terminal 100 and/or the auction participant of the second terminal 200 to input to the first terminal 100 and/or the second terminal 200 the authentication materials attached to the created transaction receipt, Then verify whether the input authentication information is normal.

The encryption processing unit 406 is coded in the following manner, that is, issuing the transaction note specified by the auction initiator of the first terminal 100 and/or the auction participant of the second terminal 200, and then storing the encrypted information in the contract-related information database 409 middle.

Also, the control unit 402 controls the operation of the auction transaction intermediary server 400 . In particular, the control unit 402 determines whether a contract for the auction item has been concluded between the auction initiator of the first terminal 100 and the auction participant of the second terminal 200 and then detects a corresponding transaction note. The control unit 402 also performs various control operations, for example, an operation of requesting the auction initiator of the first terminal 100 and/or the auction participant of the second terminal 200 to input authentication materials into the first terminal 100 and/or the second terminal 200 . Also, the control unit 402 analyzes auction conditions and bid statuses, and performs optimal auction evaluation activities.

Also, the memory 407 stores various programs operated by the control unit 402 while storing temporary data generated when the control unit 402 operates the programs for a short time.

FIG. 3 is a flowchart illustrating an optimal auction method using a network according to the present invention.

As shown, an optimal auction performs a sequence of operations in sequence. First, when a user is connected to the auction transaction intermediary server 400, it is determined whether the user is an auction initiator or an auction participant in operations S101, S102, and S107. Then, in operations S103 to S106, if the user is an auction initiator, the user is asked to input information related to characteristics of the auction item, basic requirements of the auction item, evaluation items, evaluation methods, and the like. Once the information is received, it is stored in operations S103 to S106. If it is determined that the user is an auction participant, in operations S109 to S112, the user is asked to input information related to the auction proposal. Once the input information is received, it is stored in operations S109 to S112.

Next, in operations S113 and S114, the stored information on the auction input by the auction initiator and the stored information on the proposal input by the auction participants are compared with each other and then searched. In operation S115, if the basic requirements of the auction determined by the auction initiator do not match the proposals made by the auction participants, the auction participants are notified of the reason for rejecting the auction transaction. If the basic requirements match the proposal, it is determined how many people participated in the auction. In operations S116 to S118, if a certain person participates in the whole process of the auction up to the auction termination point set by the auction initiator, the auction participant and the auction initiator will be notified that the transaction is successful.

If there are multiple participants in the auction, the overall evaluation results are analyzed according to the evaluation items and evaluation methods, and then compared with each other to select the best bidder. After the bidders are selected, the auction initiator and the selected bidders are notified that the auction transaction is over, and then in operation S119, a transaction note is created. In operations S120 and S121, settlement procedures are performed, and auction items are delivered.

If multiple auctions are arranged to be performed continuously according to the predetermined schedule, then in operation S122, each auction activity is continuously performed until the termination point of the auction. Also, in operation S123, it is determined whether those participants who were not selected as successful bidders in the previous auction event are likely to participate in another auction transaction according to the schedule, and whether there are new participants. If the answer is yes, the auction transaction is facilitated again. Once it is confirmed that the transaction is successfully concluded, that is, in operations S124 and S125, the bidding price, the deposit, etc. are paid. In operation S126, it is checked whether there are remaining items for the next auction event or whether there are more scheduled times for the auction event. If the check is positive, the remaining participants are allowed to bid on the auction, otherwise, the auction is terminated.

Specifically, for the optimal auction method using the above network, in operation S101, the auction initiator or auction participant uses the first terminal 100 or the second terminal 200 to connect to the auction transaction intermediary server 400 through the communication network 300 . Once the user (ie, the auction initiator or the auction participant) is connected, in operation S102 and operation S107, the control unit 402 of the auction transaction intermediary server 400 will determine whether the connected user is the auction initiator or the auction participant. In the present invention, it is only necessary to create two icons for the auction initiator and the auction participant on the main screen in advance, so that the auction initiator and the auction participant can be easily distinguished. If the user is neither the auction initiator nor the auction participant, return operation S108 to the first operation S101 or monitor the required transaction status.

Meanwhile, if it is determined that the user is the auction initiator, operation 5103 starts requesting the auction initiator to input information related to the auction. In operation S104, it is checked whether the acquired information is input by the auction initiator. Once the auction-related information is input, the auction-related information is received in operation S105, and the received information is stored in the memory 407 in operation S106.

At this time, the information related to the auction includes the following. The auction initiator provides the characteristics of the auction item and sets the basic requirements of the auction. Also, depending on the characteristics and the desired profit level, the auction promoter can add evaluation items for comparing and evaluating auction participants as appropriate, and enter these evaluation items to select from among those participants who meet the basic requirements and reference scores of the evaluation items The best bidder that is closest to the auction sponsor's preferences or intent or that maximizes the auction sponsor's profit is selected. Also, for the information related to the auction, the auction sponsor sets the evaluation method and the basic requirements of the auction. Therefore, within the range of satisfying the basic requirements, the participants can apply for the auction with different proposal conditions (in terms of price and various matters) from each other.

Auctions can be conducted under a trading scheme set according to an overall scoring table to facilitate checking the progress status of the auction as well as auction proposals among multiple participants and trading with each other. Such a transaction form including the overall scoring table as shown in FIG. 5 is written into the auction transaction intermediary server 400, and when the auction initiator selects a transaction according to the overall scoring table, the evaluation basis, evaluation score and evaluation level will be displayed in real time etc., so that participants can bid after reviewing these offers. Also, the auction transaction intermediary server 400 includes a virtual evaluation unit so that participants can simulate how their proposals are evaluated before applying for an actual auction. Through this simulation, participants are able to easily decide on proposals for the auction.

At the same time, in the process of inputting information and basic requirements related to the auction, the auction initiator can select the desired auction transaction type, such as reverse auction, lease auction, reverse lease auction, and the like. Once the desired transaction type is entered, the auction transaction proceeds according to the preset auction process, eg, someone who initiates the auction, someone who pays the bid.

If it is determined in operation S107 that the user is an auction participant, the auction participant is requested to input information related to a proposal for the auction in operation S109. Then, in operation S110, it is checked whether the auction participant has input the acquired information. Once the acquired information related to the auction proposal is input, the acquired information is received in operation S111 and stored in the memory 407 in operation S112.

Subsequently, in operations S113 and S114, the auction-related information input by the auction initiator and the proposal information input by the auction participant are compared with each other and then searched. If the basic requirements provided by the auction initiator do not match the proposal information, operation S115 will be triggered to notify the auction participants of the reason for rejecting the auction transaction. If the proposal information satisfies the basic requirements, in operation S116, it is checked whether there are multiple participants in the auction. If there is one participant until the auction is terminated, then in operation S118, the auction initiator/auction participant is notified that the auction transaction has been realized.

If there are multiple participants who have provided auction proposals that meet the basic requirements set by the auction initiator, then in operation S117, analyze and overall evaluate proposals made by these participants according to the corresponding scores of the evaluation items set by the auction initiator auction proposal. After the overall evaluation, the participant who provided the best proposal is selected as the successful bidder, and then, the auction initiator/participant is notified that the auction transaction has been realized.

In the present invention, if the auction initiator selects a rental auction in which the auction initiator as the lessor collects the rent paid by the lessee, select the price) participants. In the case of a reverse auction in which the auction sponsor pays the successful bidder a sum of money as payment for the purchase or lease of the item/property, choose the price) participants. In the case of a reverse auction in which the auction sponsor pays the successful bidder a sum of money as payment for the sale or lease of the item/property, choose the price) participants. In the case of a reverse auction in which the auction sponsor collects payment from successful bidders as payment for the purchase or lease of the item/property, choose the price that is closest to the auction sponsor's preferences or intent and maximizes profit (i.e., provides the greatest profit ) participants.

Among the various auction types above, if the auction initiator selects lease auction or reverse lease auction, an additional evaluation can be performed to achieve an optimal auction. For lease auctions or reverse lease auctions, there is a recurring situation where multiple participants can be combined for leases based on a schedule of leases/rentals. Therefore, when evaluating auction participants, these combined participants can be considered as a group, and then, an additional process is performed by comparing the proposals made by the individual and the proposals made between the individual and the combined group Or proposals made between combined groups to select the best bidder, which may be the individual or combined group that is closest to the auction initiator's preferences or intent and maximizes profit.

The central processing considers the lease schedule, the auction termination point for each lease schedule, and the auction participant's application schedule, by using a program installed in the auction transaction intermediary server 400, for each possible case, will fit the common lease Participants are combined into groups, thus resulting in combined groups. Furthermore, the auction participants whose schedules influence each other's lease transactions are compared and evaluated simultaneously with each other. Some groups can still be left uncombined as desired.

If the auction transaction belongs to the lease type, the basic lease information includes the lease term, the auction termination point of each schedule within the lease period, as the main auction conditions set by the auction initiator. Those who want to rent can set the total lease period according to their needs: XX time, Y days, D weeks, F months, C years, etc., and can also set the basic unit lease period, or there is no limit to the basic unit lease period, and the available lease period and minimum lease term. Also, rental conditions can be differentiated by adopting different minimum rental prices or unit prices that can be set to vary according to rental schedules, or surcharges, discount rates, and the like. In addition, the total available lease period can be divided into several lease periods according to needs, so that each lease period can be independently auctioned, and a single participant or multiple participants who want to rent can negotiate the total The lease period or individual sub-terms participate in the transaction. That is to say, by selecting the input conditions set by the rent-seeker, the total lease period or segmented lease period can be divided into multiple sub-segments according to the application of the participant who wants to rent, thereby realizing multiple transaction activities.

In other words, transactions can be made by dividing the available lease period registered in the total lease period or segmented lease period into several time periods according to the application made by the participant who wants to lease. Specifically, multiple rent-seekers can choose a desired time period within the total available lease period or segmented available lease period registered by the lessor as appropriate, thereby participating in the auction transaction.

Moreover, adopting a schedule-based transaction model facilitates verification of the progress status of leasing activities and schedules of multiple participants, and transactions with each other. The lessor scores available and unavailable leases on a timetable (in the form of a calendar as depicted in FIG. 6 ), and sets evaluation methods, such as lease conditions, lease priority basis for auctions, etc. Then, the renter checks these offered conditions and enters the desired renting date and unit price, and can participate in the transaction after verifying how many people participated in the renting activity, priority of bids, rating, evaluation price, etc.

In addition, several subsequent auctions can be carried out, because after the special setting of the lessor, the termination point of each lease can be extended to the last available lease period of the total available lease period, and the termination point of each lease can also be advanced . That is, in the former case, taking into account the handover period of the item/property to be rented, the auction will be terminated on a date prior to the lease decision date for each available lease date based on the schedule, and proceed to the other following Lease transaction activity until the last available lease period. In other words, although the lessor sets the conditions for determining the lease term in advance, each lease is determined based on how many people who can participate in the subsequent lease transaction activities apply for the lease instead of the state of the auction where one lease contract terminates the entire available lease term. The end point of the auction for the specified date.

The handover period of the item/property to be rented is an essential requirement of the rental activity and may take a day or several days depending on the item/property to be rented. Therefore, transactions should be conducted by allowing the required time including deposit period and item/property handover period before the desired lease date, especially, when there are multiple rent-seekers participating in the lease auction. The time required is critical. Therefore, taking into account the time required for this period, the lessor enters or selects a lease decision date for each available lease date in advance of the scheduled date. It should also be noted that in the case of an auction, the auction termination period for each lease term is not the total auction termination period. Each available lease period includes a separate lease decision period as a result of prior entry or selection of the lease termination period. Thus, if the leasing activity continues for several days, among many expected leasing dates, the leasing decision period on the first day represents the leasing decision period of those applicants who successively rent later, and in the process of evaluating other rent-seekers, Also used as a reference point for assessing the lease decision period.

Therefore, if the lessor inputs the total available lease period and conditions, the auction transaction intermediary server 400 evaluates the participation conditions and participation conditions of those who will participate in the rental activity, and then selects the optimal rent seeker. If a person applies for a lease for consecutive days when there are multiple rent-seekers participating in the auction, among multiple expected lease dates, determine the first start date as the overall reference date for consecutive expected lease dates, and apply lease decision period. Apply this process equally to other rent-seekers to use as a relative comparison reference for selecting a rent-seeker. That is, the lessor selects a lease decision period for each available lease date prior to the scheduled date. Depending on the participation of the rent-seeker, the lease decision period can be retroactive to a specified date. According to the traceable decision period, evaluate the total price, average unit price, lease term, etc. to select the optimal participant who applies for lease.

Thus, if there are multiple parties to the lease and the desired lease period and lease point partially or completely overlap each other or are within the bounds of a valid transaction, for example, within the handover period of the item to be leased, then for each day of the lease The application determines the time frame of the lease for an overall assessment. However, each overlapping expected lease date is not evaluated; instead, the time frame for determining the lease is applied according to the lease start date in the lease period requested by the participant to be leased, and the bidding conditions are compared with each other according to the same reference point.

Where an item/property is leased under an extended schedule, if there is a date when no one applies for the lease, the lessor may amend the unit price or conditions, or the timing of no-let dates or available-to-let dates, to continue the lease transaction . In the present invention, the same conditions are maintained with respect to the previous contract of the rental.

At the same time, in lease auctions, after the lessor sets the conditions, this lease transaction can be carried out with consideration of depreciation, because if the lease activity continues beyond a certain period, then the item/property to be leased can be regarded as a lease property of the person without returning the article/property to the lessor. For this kind of transaction, the lessor can choose the final owner among the lessees who are willing to lease for a long time, the highest bidder, the last lessee, etc., or they can choose the owner randomly.

Also, if there are multiple lessees, there will be transportation costs and lost leasing opportunity time during the communication between the lessor and the lessee and the transaction between the lessor and the selected lessee. Therefore, the lessee who proposes the best lease terms is selected by considering the length of time for losing the lease opportunity. If the lessee proposes the same lease price within a limited time, the short-term lessee will not be selected, but the long-term lessee will be preferred, because the loss amount of the long-term lease in this respect is less. If the unit prices are different, the amount of loss is calculated so that the optimal lessee can be selected.

If there has always been a lessee, keeping the lease going, the rented item/property is returned to the lessor and then rented out again to subsequent lessees. The front lessee can also directly hand over the rented item/property to the later lessee, thereby reducing distribution costs and shortening the time for lost rental opportunities due to return and handover.

For reverse auctions, lease auctions, and reverse lease auctions, the basic requirements set by the auction initiator can even include specific qualifications, such as the age and gender of the auction participants, in addition to the characteristics of the item being auctioned, the bid price, and the lease period . Moreover, the auction initiator can set evaluation items for auction participants who meet the basic requirements, as well as a score or grade for each requirement of these evaluation items. As described above, evaluation items can also be arbitrarily set by the auction initiator. In this case, bidders are selected after evaluation according to evaluation priority. If the evaluation priorities are the same, the next evaluation item is evaluated to select the bidder.

In the above auction process, even if a certain auction participant bids better than other participants, this bidding advantage does not guarantee that he is a successful bidder, because it is closest to the preference and intention of the auction initiator or can maximize The profit participants may be others. This operation of evaluating and selecting bidders that are closest to the preferences and intentions of the auction initiator and can maximize profits is performed by using a program installed in the auction transaction intermediary server that analyzes the bids set by the auction initiator. Conditions and application for auction participants.

For example, in the case of auctioning a vehicle, it is assumed that the auction promoter sets basic requirements for this auction that the displacement is greater than about 2,000cc, the energy efficiency is higher than the middle level, and the bid price is less than about 30,000,000 won, and the level of energy efficiency and As far as the evaluation items including airbags are concerned, even if the price is high for the buyer, if the energy efficiency level is also high, the cost of use can be reduced, and if there are airbags, personal safety can also be ensured. So score those things, prices, etc. to give an overall assessment of it. If price is the most important, then set the score of price as high and the rest of the evaluation items as low.

Figures 4 and 5 are example transaction methods based on the respective overall scoring tables applied to the optimal auction method according to the present invention.

Especially in Fig. 4, the auction promoter sets the basic requirements by listing a price of less than about 15,000,000 won and a displacement of more than about 2,000cc, and gives evaluation items and scores that are less than about 10,000,000 won, less than Bids of about 12,000,000 won, less than about 13,000,000 won are awarded 30 points, 20 points and 10 points respectively; if the displacement exceeds about 2,000cc, 5 points are awarded for every about 100cc. The manufacturing company is Hyundai, Toyota and other companies, respectively, 10 points, 5 points and 3 points; and the vehicle color is white, blue and red, respectively, 10 points, 5 points and 3 points. These evaluation items are evaluated collectively to select the best bidder. When the scores are the same, the evaluation is performed according to the priority of the evaluation grade, preferably, the priority order of price, manufacturing company, color and displacement.

Figure 5 shows an example situation of purchasing an airline ticket. Specifically, the auction initiator sets the basic requirements by listing the departure airport, destination, boarding date, and fare, and registers evaluation items such as seat position, flight route, fare, boarding time, and information about the evaluation Item's evaluation reference score. Then, according to the overall scoring scheme, the optimal conditions closest to the intention of the auction initiator are searched to reach the desired transaction.

For example, if the auction promoter sets the basic requirement that the departure from Incheon Airport arrives in San Francisco on December 1, 2005 and the fare is less than about 1,200,000 won, and adds evaluation items and specific points for the evaluation items, that is, from the set From about 1,200,000 won, 5 points are awarded for every reduction of about 100,000 won; 10 points for direct routes and 5 points for stopover routes; 5 points for window seats, 3 points for aisle seats and middle seats 1 point; Korean Air, United Airlines, and others received 10, 5, and 3 points, respectively.

Figure 6 shows an example transaction method based on a rental schedule in accordance with the present invention.

In FIG. 6, the lessor sets conditions as follows. First, the minimum unit period for renting is more than 2 consecutive days; the time limit for deciding to rent is 4 days before the desired renting date, including the 2-day handover period; the evaluation method of the bidder is an overall evaluation or a grade-based evaluation; if it is For grade-based evaluation, the order of priority is total price, average unit price, and the principle of "first come, first served"; consecutive rental applications are evaluated based on one application, not separately. According to the timetable, from April 1 to 26, the overall assessment method is selected, while April 27 and 28, the grade-based assessment method is selected.

Among them, the lessor registers April 1 and 2 as rentable dates, and sets the time required for handover to the next lessee as 2 days. Since the lessor is in contact with the previous lessee, it is indicated in the schedule from April 2 (which is the last day the previous lessee’s lease expires) to April 4 (which is 2 days away from April 2 days) are not rented out.

On April 5th, according to the specific settings made by the lessor, the lease decision date and time are set to 00:00 on April 1st, which is 4 days before the rentable date. On April 6, according to the specific settings made by the lessor, the lease decision date and time are set to 00:00 on April 2, which is 4 days before the rentable date.

From April 7th to 10th, set the rental decision date 4 days ago as in the previous case. However, the second bidder, Dong-Won Choi, offered a 5-day rental period from April 6 to April 10, so consider this case as one rental application. Therefore, the lease decision date for the entire desired lease period is set as the first day of the desired lease period, ie, April 6. April 11th is the last day for Dong-Ryeol Sun, the first bidder, to take the lease, and even though the lease period applied by the first bidder is 4 consecutive days from April 8th to April 11th, it is considered a Lease application, but the lease period applied for by the first bidder overlaps with the lease period applied for by the second bidder. Therefore, the lease decision date of the second bidder is used as the lease decision date of the first bidder, so that the two bidders can be evaluated equally. When the desired lease terms proposed by a plurality of parties to lease overlap with each other, the lease decision date is set to the earliest date among the different expected lease dates to evaluate the multiple parties.

Although April 12 did not overlap with the participant's desired date, it was only one day away from the previous rent-seeker's lease period. Therefore, if there is a contract with the previous rent-seeker, then this day cannot be rented, because there is a 2-day handover period. Therefore, it is necessary to evaluate the current rent seeker and the previous rent seeker to determine the best bidder. For this reason, when leases proposed by multiple participants overlap with each other, or within the effective trading days including the handover date (in this case 2 days), the participants corresponding to these situations are evaluated together , in order to choose the optimal transaction taking into account the loss of rent caused by the handover period.

For the third bidder, Tae-jee Seo, no handover period is allowed relative to the first bidder, but only 1 day handover period is allowed for the second bidder. Therefore, since the lease period applied by the third bidder is within the effective handover period of the first bidder and the second bidder, the lease decision date of the third bidder is also set at 00:00 on April 2 .

The second lessee applies to rent from April 22nd to April 24th, consider him/her a separate applicant and this is assessed independently of the other application from April 6th to April 10th lease application. That is, those applications that are separated by more than the pre-set handover period are considered as distinct applications.

Therefore, the auction transaction was confirmed, and the third bidder who put forward the highest price was selected to rent from April 12th to April 15th, and the rent was about 200,000 won. Choose the second bidder to rent from April 22 to April 24, and the rent is about 140,000 won.

The overall assessment approach was used in the above cases. For April 27 and 28, assume a grade-based assessment method. So, based on the first priority total price, both are about 70,000 won, the second bidder and the third bidder have the same priority, and according to the second priority average unit price, these two bidders have the same priority, so the third priority "first come, first served" principle is adopted, and the second bidder is selected, because according to the first come first served principle, it is earlier than the third bidder.

In FIG. 7, the person to rent sets conditions as follows. First, the minimum unit lease period is more than 2 consecutive days; the time limit for deciding to lease is 4 days before the desired lease date, including the 2-day handover period; the assessment method of the lessee is an overall assessment or a grade-based assessment; if it is grade-based evaluations, with priority in the order of average unit price, total price, and advance sales; and consecutive lease applications are evaluated against one application, not separately. According to the timetable, from April 1 to 24, the overall assessment method is selected, while from April 25 to 28, the grade-based assessment method is selected.

Although the transaction types and decision methods are the same as those described in Figure 6, leases can still vary according to the bidder's conditions. For example, the second bidder has the highest priority by proposing a total price of about 200,000 won. However, the 1st and 3rd bidders have enough of a 2-day handover period between the requested lease periods, so when the 1st and 3rd bidders are selected to trade, the total bid becomes About 240,000 won, which was more than the bid of the second bidder. Therefore, the auction transaction intermediary server 400 evaluates the first bidder and the second bidder as optimal lessees.

The above-mentioned situation of realizing the transaction is possible because of the following reasons. Many bidders applied for leases that overlapped each other, and the third bidder applied for a lease that was just one day away from the other bidders' leases, but within the 2-day handover period, therefore, the same bid was used for the third bidder or the same rental decision date and time. Also, the third bidder may leave a 2-day handover period with respect to the first bidder, thus allowing the third bidder and the first bidder to conduct auction transactions.

The above situation adopts the overall assessment method from April 1 to April 24. But from April 26-28, a grade-based assessment method will be used. Specifically, in the bidding state using the rank-based method, although the first bidder had priority over the other bidders in terms of total price, the second bidder who proposed an average unit price of about 40,000 won was selected because according to the rank-based The evaluation method, the average unit price takes precedence over the total price.

Next, the operation S119 described in FIG. 3 is triggered to create an online transaction document, and then, in operation S120, the settlement procedure of the contract is handled. In the present invention, during settlement, if the auction initiator sets a deposit for possible damage, loss, and cancellation of the transaction during the entry of information related to the auction, the successful bidder needs to set the auction initiator A sum of money is deposited to the insurance agency 500 or broker. If the deal goes through, the successful bidder gets their deposit back.

After settlement, in operation S121, the auction item is handed over to the successful bidder. Then, in operation S122, a signed auction state and an unsigned auction state are displayed, so that subsequent participants can apply for the auction. According to the existence of subsequent auction participants determined in operation S123, if there are subsequent auction participants, the auction process returns to operation S112. Otherwise, in operation S124, it is verified whether each contracted auction is performed according to the contract. Then, in operation S125, the selected bid is settled and the deposit balance is returned. In operation S126, it is also checked whether there are any remaining items for the next auction. If the check result is positive, the auction process returns to operation S105, otherwise the auction is terminated.

According to a preferred embodiment of the present invention, an optimal auction method is proposed to overcome the limitations of common auction methods. According to this proposed optimal auction method, various types of auction transactions, such as optimal reverse auction, lease auction, and reverse lease auction, can be implemented through a network such as the Internet. Of course, this proposed optimal auction approach can be modified to apply to other transaction types.

Also, the items to be auctioned according to the optimal auction method can be various tangible and intangible items including photocopiers, water filters, medical instruments, automobiles, information, technology, rights, real estate, memberships, advertisements, and the like.

Although the present invention has been described and illustrated herein with reference to its preferred embodiments, those skilled in the art will appreciate that various modifications and changes can be made therein without departing from the spirit and scope of the invention. Thus, it is intended that the present invention covers the modifications and changes that come within the scope of the appended claims and their equivalents.
