The present invention relates to a method for providing bid analysis information on a network, and collects basic information about bidding by an online method, and converts the basic information to generate various conversion information that can be analyzed by bidding, and to meet the needs of users. Provide customized bid analysis information.

Electronic bidding is the electronic processing of auctions, short selling, and open bidding. In the case of offline bidding, it may also mean electronically processing bid data using a button input method. Recently, bidding announcements are made on the Internet, and in many cases, a bid for the corresponding delivery is received from the homepage of the company.

An overview of the current e-bidding system shows the tender announcements, bidding, and bidding by the Public Procurement Service or its own e-bidding system regarding the construction of facilities, purchases of goods, and service orders that require governments, local governments or public institutions and other organizations. A wicket is carried out to finally select a partner.

The process of e-bidding is briefly described as follows. The Public Procurement Agency's electronic procurement system, “Nara Marketplace,” or other organizations' own procurement system, announces the bidding of bidding targets. Bid announcements include information on bidding, bidding methods, bidding qualifications, site descriptions and design documents, submission of bids, bid deposits and attributions, open / closed bids, bidder decisions, invalidation of bids, pledges of integrity contracts, and others. do. After the bid announcement, a plurality of reserve prices are generated and arranged in a random manner based on the base amount, and a predetermined price is determined by arithmetically averaging the reserve prices corresponding to the number most selected by the bidding bidder. The lowest bid price is determined by multiplying the estimated price by the bid base rate, and the lowest bidder among the bidders above the minimum bid price is determined as the bidder. This will be described in more detail below.

The base amount is an amount to be used as a basis for bidding, and a plurality of preliminary prices are calculated based on this, and the bidder is a standard for calculating a bid amount. The base amount will be disclosed at the time of tender notice or during the tender notice. The basic amount depends on the bidding target. For example, in the case of bidding for the construction of a facility, it is very difficult to calculate the same amount because the construction site, the scale of construction, the design method, and the applied unit price are different.

The plurality of reserve prices are prices generated by a predetermined number within a predetermined range on the basis of the base amount, and the plurality of reserve prices can be confirmed at the time of ticket opening. For example, a plurality of reserve prices are generated by random number generation in the case of an e-procurement system 'country market' operated by the PPS, and the generated reserve prices are raised to less than 100 won. According to the preliminary price generation criteria, the Ministry of Government Administration and Home Affairs generates 15 values within the range of + 3% to -3% based on the base amount. PPS generates 15 values in the range of + 2% to -2% based on the base amount. In addition, a preliminary price and the number thereof are generated within a predetermined range for each client.

A plurality of preliminary prices are randomly generated by the bidding executive of the ordering party from the time of the bid notice to the open bill, and the number selection screen 10 is arranged on the number selection screen 10 as shown in FIG. Each reserve price is randomly assigned to each number 12, and the generated plurality of reserve prices and the numbers assigned to each are encrypted and stored.

The bidder will select two of the numbers allocated one-to-one to each of the plurality of unlisted reserve prices. The actual amount of the reserve price for the assigned number can only be checked at the ticket gate. The ticketing will be conducted by the bidding officer after the ticketing time indicated in the bid notice.

The bidder selects two of the numbers in which a plurality of preliminary prices are arranged in an unpublished state at the time of bidding, and a predetermined price is determined by arithmetically averaging the preliminary prices corresponding to the four most selected numbers. In the case where ten reserve prices are generated, a predetermined price is determined by arithmetically averaging the reserve prices corresponding to the three most selected numbers. If the same number of choices among bidders is selected, the previous number determines the scheduled price. If the number of bidders is small and the number of choices is less than four, the bid executor selects randomly among the unselected numbers.

The lower bid price is a reference price that determines the bidder. The price is calculated by multiplying the determined bid price by the 'baseline rate of bidding.' Here, the bidding base rate is determined in advance by the estimated price of the construction (base amount-VAT), the type of construction industry, bidding method, etc., if the bidding target is a construction, for example, Table 1 below are some examples of the bidding baseline Is showing.

[Table 1] Estimation Rate of Investor by Owner

division Amount Category: Estimated Price Perspective Criteria General construction Professional construction, equipment Electricity, communication, fire fighting PPS Less than 300 million Less than 100 million Less than 300 million 87.745% 3-10 billion won 1-10 billion won 1-10 billion won 86.745% 10-50 billion won 10-50 billion won 10-50 billion won 50-100 billion won 50-100 billion won 50-100 billion won 85.495% Korea Housing Corporation Less than 300 million Less than 100 million Less than 300 million 87.745% 3-10 billion won 1-10 billion won 1-10 billion won 86.745% 10-50 billion won 10-50 billion won 10-50 billion won 50-100 billion won 50-100 billion won 50-100 billion won 85.495%

The bidder who bids the lowest amount among the bidders who offered the bid amount above the lower bid price is determined as the bidder. That is, the bidder who bids the amount above the lower bid limit corresponds to this. The final successful bidder will be determined based on the preliminary screening criteria for successful bidders, and if the successful bidder is eliminated, the final successful bidder will be determined through the same screening process.

Currently, the number of companies participating in the bidding is about 100,000 companies in Korea, and the current e-bidding system has significant significance in terms of transparency and rationality of procurement. However, bidders generally respond to the bidding without any special bidding analysis, and some companies use the paid bidding information site on the Internet to calculate the bid amount based on only partial information or generate bid data by themselves. We are collecting and bidding. In severe cases, bid analysis may be referred to an outside company, but effective analysis is difficult to obtain good results.

On the other hand, since the bid announcement and the bidding information is announced by the bidding system operating institutions, bidding participants have a inconvenience to inquire the announcement details of each bidding system operating institutions. To alleviate this inconvenience, there is a website that provides information related to bidding to bidding participants, but only provides simple information such as bidding information and successful bidding results, and bidders can analyze the bidding more objectively. Information is not provided.

Given this reality, it will be necessary to provide bidding participants with high quality bidding analysis information so that more companies can conduct business well through bidding. However, it is still not providing a more objective and customer-oriented bid analysis information for a number of bids that are being carried out by administrative agencies and other bidding companies.

The present invention has been made under such a technical background, and it is an object of the present invention to provide a bid analysis information providing method so that anyone participating in bidding can be provided with more objective bid analysis information.

In addition, another object of the present invention is to allow bidding companies to increase the probability of successful bidding based on the bid analysis information.

Other objects and other features of the present invention will be presented in more detail in the following detailed description.

In order to achieve the above object, the present invention provides a bid analysis information providing method related to an electronic bidding system that allows a plurality of bidders to participate at least a part of the bidding process using a wired or wireless network, a plurality of bids Information on a plurality of reserve prices calculated from the notification event, an arrangement of a plurality of numbers each assigned to the plurality of reserve prices one-to-one, and the number of times the bidder selected each number included in the arrangement of the plurality of numbers. A first basic data collection step of collecting each of the separate data to the main server; Generating first converted data on a main server which converts the plurality of preliminary prices among the data obtained in the first basic data collecting step as a percentage of the bid base amount determined in each bid notification event; A second basic data collection step of collecting, on the main server, a predetermined price obtained from the number selected by the bidder most frequently as a result of the bidding of each bid notification event; Generating second converted data on a main server by converting the predetermined price obtained from the second basic data collecting step into a percentage of the bid base amount determined in each bid notification event; Receiving, at the main server, selection information related to the content of the bid selected by the user connected to the main server using a wired or wireless network; Bid analysis on a network comprising: providing, on a main server based on the selection information, bid analysis information in which the items related to the selection information selected by the user among the second converted data are arranged in a table or graph form. It suggests how to provide information.

The bid analysis information is preferably arranged in the order of the size of the second conversion data in a table or graph format.

The bid analysis information may further include third transform data corresponding to a deviation value between the sorted second transform data. The bid analysis information may further include fourth transform data corresponding to an analysis value obtained by dividing the deviation value by a predetermined value and adding the split deviation value to the second conversion data.

The selection information related to the contents of the bid received from the user connected to the main server using a wired or wireless network may include the bid announcement name, bid notice number, bid ordering agency name, bid registration deadline date, bid estimate price and bid basis. At least one selected from an amount of money, a bidding target, a bid participation area, a bid schedule, and a ticket opening date and time is preferable.

The arrangement of the plurality of preliminary prices among the first basic data may be arranged in order according to the size. The first basic data collecting step may further collect information on the number of times selected as a number for determining a predetermined price for each number included in the arrangement of the plurality of numbers.

The method of providing bid analysis information according to the present invention may further include providing information representing a change in the plurality of reserve prices in a table or graph form, and further, ordering the arrangement of the plurality of reserve prices according to size. Arranging as described above may further include providing information expressed in a table or graph format.

In addition, the bid analysis information providing method according to the present invention through the processing on the main server based on the selection information, the change trend of the second conversion data associated with the selection information selected by the user among the second conversion data or The method may further include providing information expressed in a graph form. Information expressing the change trend of the second converted data in the form of a table or graph may be provided in a limited range selected by the user.

In addition, the bid analysis information providing method according to the present invention may further comprise the step of collecting the lower bid price and the successful bid price calculated from a plurality of bid announcement events that were sold out, using a wired or wireless network The method may further include receiving a projected amount of money determined by a user connected to the main server.

The bid analysis information providing method according to the present invention is preferably carried out on a wired or wireless network, for example, bid analysis to a user connected to the Internet using a computer, PDA, DMB, mobile phone, other portable wireless communication devices, etc. Information may be provided. In addition, the bid analysis information providing method according to the present invention can be performed through a website on the Internet, in this case it will be able to provide more customized information through two-way communication with the user accessing the website on the Internet. . In addition, the bid analysis information providing method according to the present invention may support the bidding participant's electronic bidding process in connection with the existing electronic bidding system.

2 schematically illustrates a system for performing a method for providing bid analysis information according to the present invention. The bid analysis information providing system 100 corresponds to a main server that collects information, converts data, and performs bidirectional communication with a user while controlling the overall process. The system 100 includes at least one basic database 110, which is linked with a plurality of electronic bidding systems 130 to collect and store basic information related to bidding. The system also includes at least one transformation database 120, which generates and stores processed secondary, tertiary and / or quaternary transformation data from the primary database. The collection and processing of data may be customized according to the needs of the user 140, and the system 100 controls the collection and processing of information through wired or wireless communication with the user 140, and the user 140. Bid analysis information may be provided in a desired form according to the needs of the user. In FIG. 2, the number of the electronic bidding system 130 and the number of users 140 are merely exemplary, and in fact, a larger number of systems and users will be involved.

In bid analysis, it is important to predict how a plurality of reserve prices are arranged and which number the bidder selects. The object of analysis is important for such predictions, and it is most reasonable to base the results of the existing wickets. Therefore, in the present invention, as the basic database, a plurality of preliminary prices (rates) determined in the existing ticketing results, an arrangement of each preliminary price, a bidder's selection number, a predetermined price, and related bidding information are selected as basic analysis information Database them separately. The basic database is preferably stored in conjunction with the contents (bidding information) of the relevant bid announcement, that is, bid announcement number, bid target, bid date and time, base price, successful bid price. Such bidding information may be a basis for calculating the information when the personalized information is provided according to a request of a user connected through a wired or wireless network. For example, differentiated information may be provided according to bidding targets, bid notice timings, base amounts or winning price ranges.

3 shows a schematic flow of a method for providing bid analysis information according to the present invention. First, basic information related to a bid is collected or received from an electronic bidding system or the like to form a first basic database (step S100). The basic information may include a plurality of preliminary prices, arrangements of preliminary prices, selection numbers of bidders, and the like, generated in each bid announcement as described below. Based on this basic information, the first transform data for bid analysis is generated and stored (step S110). Next, as a further basic information, a predetermined price, which is a standard of a successful bid lower limit price in bidding, is collected or received in whole or selectively for each bidding announcement and is made into a second basic database (step S120). Based on the second basic data, second converted data is generated and stored as information for actual bid analysis (step S130). This second conversion data is arranged in order of magnitude, for example, by converting the estimated price into a percentage of the base amount (i.e., generating the expected price rate), and obtaining a difference (i.e., a deviation) between the expected price rates and predetermined at each estimated price rate Value can contain distribution values. The second conversion data may be used as a criterion for determining the bidding amount of bidding participants as will be described later. After generating the second conversion data, information related to the bidding, for example, bidding target, bidding time, etc., is received from the bidding participant or the user corresponding to the person who wants to analyze the bidding (step S140). This selection information may be a criterion for generating customized information that meets user requirements in providing bid analysis information. In some cases, instead of or in addition to step S140, in response to the first basic data collection step (step S100) or the second basic data collection step (step S120), user request information is received (steps S140 'and S140 "). When the information processing for bid analysis is completed, the bid analysis information expressed in the form of a table or a graph is provided according to a user's request (step S150). It may be provided through, for example, via a portable terminal such as a PDA, a DMB, a portable communication device, or via a website on the Internet. .

1. Basic Analysis Information

The basic analysis information collects the bidding information determined by the existing electronic bidding system through, for example, online and stores it in the basic database 110 as first basic data. For more objective and predictable analysis, it is preferable to convert each basic analysis information into a primary database as follows. FIG. 4 shows the first basic database 200 which is the basis of bid analysis in the present invention, and the first transformed database 210 converted therefrom. The first basic data includes a plurality of preliminary prices, which are the basis of bid analysis, and related bidding information (bid announcement number, bid date, bid amount, successful bid price, etc.), and the first converted data converts the plurality of preliminary prices. It includes a plurality of preliminary price rate, the details thereof are as follows.

a. Multiple reserve price rate

In order to compare the plurality of reserve prices with the base amount, a plurality of reserve price rates expressed as a percentage of the base amount are calculated as follows.

(Spare price / base amount)-1 * 100

b. Array of reserve price rates

It is preferable to arrange the calculated preliminary price rate so that it is easy to understand. For example, the largest value is 1 and the order is determined according to the size (when the total number of preliminary price is 15). Can be arranged.

c. Bidder's selection number

The number selected by the bidder is divided into two as follows: first, the number of times the participant selects the number corresponding to each reserve price, and the second, the number selected as the number that determines the scheduled price among the selected numbers. In order to distinguish this, it is preferable to first call the number of nominations and the number of choices.

The number of nominations and the number of choices are counted separately.For example, by year, month, or year after the current arrangement method is applied (based on the country market: after April 1, 2005), by type of license, and bidder It can be classified by number, by recent ticketing schedule, and the like.

2. Transformation database for bid analysis

Various secondary conversion databases for bid analysis can be obtained as follows from the primary transformed database obtained from the bidding information of the existing ticketing results. Based on this secondary transformation database, some basic bid analysis information can be obtained. FIG. 5 illustrates a second basic database 300, a second transform database 310, a third transform database 320, and a fourth transform database 330 converted therefrom. The second basic data includes a predetermined price determined at each bid notice, and the second converted data is bid analysis data converted from the predetermined price, and includes a predetermined price rate, average rating rate, + average rating rate,- Average ejaculation rates and the like, and details thereof are as described later.

On the other hand, the third converted data and the fourth converted data are further converted data obtained from the predetermined price rate, and the predetermined price rate deviation value including the difference between the predetermined price rate and the deviation value is added to the predetermined price rate at a predetermined rate. This is the estimated price rate analysis showing the distribution. These details are as mentioned later.

a. Estimated price rate

As a result of the ticketing, the arithmetic average of the plurality of reserve prices arranged in the four most selected bidders is the estimated price, and the estimated price rate is determined by calculating the estimated price as a percentage of the base amount. That is, it can be obtained as follows.

Estimated Price Rate = (Scheduled Price / Base Amount)-1 * 100

The estimated price rate is a reference amount for calculating the lower bid price and may be the most important indicator in bid analysis.

b. Average ejaculation rate

A plurality of reserve price rates are averaged and can be obtained as follows.

Average Assessment Rate = (Preliminary Price Rate 1 + Reserve Price Rate 2 + .... + Reserve Price Rate n) / Number of Multiple Reserve Price Rate (n)

The average rate of assessment serves as an indicator for determining the change in the average of the plurality of reserve price ratios and the planned price ratio.

c. + Average ejaculation rate

The average of the + value of the plurality of reserve price rates can be obtained as follows.

+ Average assessment rate = (sum of preliminary price rates with + values of multiple preliminary price rates) / number of + values of multiple preliminary price rates (n)

+ You can judge the change between the average assessment rate and the planned price rate.

d. -Average ejaculation rate

The-value of the plurality of preliminary price ratios is averaged and can be obtained as follows.

(Of a plurality of reserve price rates-the sum of the reserve price rates with values) / of a plurality of reserve price rates-the number of values (n)

-You can judge the change between the average assessment rate and the expected price rate.

e. Successful bid price limit

As a standard amount for determining the successful bidder, the lower bid price is calculated by multiplying the determined bid price by the bid base rate, and the lower bid price rate can be obtained as follows.

Lower bid price rate = (Scheduled Price / Base Amount)-1 * 100 + Bidding Rate

The lower price limit can compare the difference with the winning price (rate) and can be used as an indicator for adjusting the deviation of the bid amount.

f. Successful bid price

The successful bid price is the amount of bids made by the successful bidder and is announced when the bid is announced. The bid price rate can be obtained as follows.

Successful bid price = (Bid price / Based bid price)-1 * 100 + Bid rate

The bid price rate can be compared with the lower bid price rate and can be used as an index for adjusting the deviation.

g. Deviation price rate of successful bid price rate compared to lower bid price limit

It indicates the difference between the lower bid price rate and the lower bid price rate (success price rate-lower bid price rate). From this deviation price rate, the difference between the lower bid price rate and the successful bid price rate can be compared. Can be used as an indicator.

h. Participating Companies

The number of companies participating in the auction, which will be announced at the time of publication. The number of participating companies can be used as an indicator of the relationship between the difference (deviation) between the lower and lower bid prices and the number of participating companies. If there are a lot of participating companies, the deviation will be small. If there are few participating companies, the deviation will be large. In other words, the deviation adjustment of the amount of investment should be adjusted according to the expected number of participating companies.

i. Deviation price ratio of successful bid (lower limit) price ratio compared to survey price ratio

Deviation from the bid price rate or the lower bid price rate relative to the bid price rate of the bidder. The difference between the bid price rate and the lower bid price rate or the bid price rate can be compared and used as an index for adjusting the deviation.

The various converted data may be stored separately or in a database in a storage medium. These information is preferably provided in the form of a table or graph in order to enable a comprehensive analysis of various bidding notices at the request of users. 6 shows an example in which such (second) converted data are provided in a tabular format.

3. Estimated Price Ratio Analysis Table

As the most important element among the bid analysis information provided by the present invention, the deviation value (third conversion data) obtained from the predetermined price rate, which is the second conversion data, and the analysis value (fourth conversion data) obtained by adding these to each predetermined price rate at a predetermined ratio There is a table of estimated price ratios. Figure 7 shows an example of such a scheduled price rate analysis table in a tabular format. 'Preliminary Deviation' refers to the deviation value, which is the difference between the estimated price rates when the estimated price rates are arranged in order of magnitude, and minutes 1, 2, ... Is the value of the analysis divided by 21) plus the estimated price rate. This analytical value can be used when calculating the estimated range for bidding analysis. The estimated price rate analysis table is obtained for the following reasons and principles.

When determining the lower bid price, less than 1 won should be raised. Therefore, the amount that is one won larger than the lower bid price calculated only in won units becomes the lower bid price.

The estimated price is generated based on the base amount, and the lower price is calculated based on the estimated price. When the inverted price is calculated by lowering the won price to 1 won, there is a difference from the originally estimated price. In other words, it becomes as large as '1 / baseline ratio'. However, the actual increase amount is 1 won, and the value calculated by dividing it by the predetermined price does not have the same value. This is because the scheduled prices do not have the same value. Therefore, when looking at the bidding results, the expected price ratio means that a value that does not come out before.

Based on these facts, the preliminary ticket price results are arranged in order of magnitude, and the difference (deviation) between the arranged scheduled price rates is calculated.

The deviation value is displayed by adding the values of 20/21, 19/21, ...., 1/21 to the value of the estimated price rate. Here, '21' of the denominator can be adjusted according to the size of the computer monitor. This is divided into the size of the apparently visible letters based on the 15 ”monitor. The larger the value, the higher the accuracy. If the number of participating companies is small depending on the type of license, that is, the deviation is large, this value may be reduced.

The table thus prepared is a scheduled price rate analysis table, and shows a planned price rate that has not been shown so far. The bid price analysis predicted by the bid analysis is selected, where the deviation represents the probability of the future expected price rate.

4. Bid Analysis Method

There can be several ways to analyze bids. In the present invention, based on the estimated price rate analysis table, it is based on selecting the expected price rate to be projected on the expected price rate analysis table, and an exemplary analysis method will be described as follows. However, bid analysis that can be performed with the bid analysis information provided by the present invention is not limited to the following examples.

a. Placement Number-> Multiple Reserve Price Arrangement-> Multiple Reserve Price Rate Analysis

The four numbers with the highest number of names and the number of choices are determined as expected choice numbers. FIG. 8 shows an example of providing information on the number of names and the number of selections in a tabular form in an existing bid notice event. Such information may be provided in various shapes and sizes depending on the degree desired by the user. Next, the expected sequence number of the determined number is determined. Then, a plurality of preliminary price rates of the determined numbers are determined. After calculating the arithmetic mean value of the determined multiple preliminary price ratios and calculating a predetermined price ratio, the range of the estimated price-rate analysis table to which a predetermined price rate belongs is selected. Next, prepare a table of changes in the expected price rate for the selected range.

The expected price rate is determined by judging the change in the expected price rate of the range selected from the scheduled price rate change table.

b. Average ejaculation rate-> Analysis of change in planned price rate

Estimated price rates can also be determined by trends in average rates and price rates. The scope of the survey is determined by selecting the range of the estimated price rate analysis table to which the expected price rate belongs. Next, after preparing the change price schedule of the selected range, the expected price rate is determined by the trend of the change of the expected price rate of the selected range.

c. + Average assessment rate-> Analysis on the change of the planned price rate

+ Estimated estimated price rates can also be determined by trends in average rates and estimated price rates. After the planned price rate analysis table to which the planned price rate belongs is determined to determine the scope of investigation, a change table of the estimated price rate for the selected range is prepared. Determine the expected price rate from the trend of the expected price rate change in the range selected from the expected price rate change table.

d. -Average ejaculation rate-> Analysis of change in planned price rate

-Estimated expected price rate can be determined by the change of average assessment rate and estimated price rate. After the planned price rate analysis table to which the planned price rate belongs is determined to determine the scope of investigation, a change table of the estimated price rate for the selected range is prepared. Determine the expected price rate from the trend of the expected price rate change in the range selected from the expected price rate change table.

e. Analyze by trend of planned price ratio

Make a table of trends in expected price rate changes and divide them into 0.1 units, and mark the same range of variation with the same value as the deviation ± 0.05 from the center of the range of change. At this time, the deviation width may be directly set by the user. The estimated range for the forecast is the range of the expected price rate fluctuations to calculate the estimated price rate range. After the change in the expected price rate change table of the selected range is made, the expected price rate is determined from the change in the estimated price rate change of the selected range in the estimated price rate change table.

In this exemplary analysis method, information provided to users such as bidders may visually provide a change in the reserve price and a change in the predetermined price rate for a certain period or for specific bid notification events. Do. FIG. 9 illustrates an example in which a value corresponding to a predetermined range (2.500 to 3.000) among a plurality of preliminary price rates is expressed in a graph format so that the user can understand the change trend and predict a future change. FIG. 10 shows an example in which the sizes of the plurality of preliminary price ratios are arranged in order according to the sizes in order to more easily understand the sizes.

On the other hand, Figure 11 is a graph showing a change in the scheduled price ratio that provides the most important factor in the bid analysis in the present invention. In the graphs shown in FIGS. 9 to 11, the horizontal axis may indicate, for example, a predetermined period, a specific bid target, and the like.

FIG. 12 is a graph showing only a change in a predetermined range (0.900 to 1.000) in the graph showing the change in the predetermined price ratio of FIG. Such information may be useful for analyzing, for example, the trend of changes in the predetermined price rate selected by the user, and for predicting the scope of the bid for the future auction.

5. Applies to actual bidding-to calculate the expected amount of the bid, adjust the deviation, select the place number

The estimated estimated amount of money is determined as follows from the estimated estimated price rate determined according to the above-described analysis method.

Probable Amount = Base Amount + (Base Amount * Estimated Price Amount)

Deviation adjustment is to reduce the difference between the expected lower bid price and the estimated bid price. Using the estimated price rate analysis table, the deviation value corresponding to the selected price price deviation value and the similar value on the estimated price analysis table is applied. do. You can also adjust the deviation using the recent history value in the estimated price rate analysis table versus the lower price limit.

In selecting a nomination number, the bidding participant may select only two numbers, and the other two may be selected by the other bidding participant. Therefore, a bidder selects two numbers that other bidders are expected to nominate, and analyzes a plurality of reserve price rates that are expected to be arranged in that number, thereby obtaining a plurality of expected price rates for their bidding. Select the number at which the reserve price rate is expected to be arranged.

It is desirable to provide the bid analysis information providing method and the process applied to the actual bid described above to the user by building a website on the Internet.

The website may basically include bid announcement information, auction information, bid analysis information, bid schedule management, bidding criteria information, various forms, convenience information, etc., using a user interface (user interface) for user convenience It would be desirable to configure.
