The fourth level of management refers to that users of the public resource transaction platform management software program are divided into the following four types, namely, national level managers, provincial level managers, city level managers and ordinary users, wherein the ordinary users refer to users registered by administrative departments, bid inviting units, bid inviting management units, experts and expert management units which do not belong to the managers, namely, the national level managers manage all the managers and the ordinary users, however, because the national level managers are difficult to be familiar with the situation of all places, the national level managers generally manage the provincial level managers, only common problems or network problems occur, the national level managers deal with the common problems, the provincial managers manage the city level managers and the ordinary users in the provincial regions, the city level managers manage the ordinary users at the city level and the county level, the management specifically refers to the approval of the registered users, the password modification after forgetting the password, the issue, return modification, audit, the issue of the bid item, the disclosure of the bid proposal and the disclosure of the expert review opinion, however, the administrator cannot delete the ordinary users under the self-management, the administrator deletes the ordinary users and the administrator under the self-management, the ordinary users or the administrator's management department is required to issue a official letter for deletion, the bidding proposal is as follows according to the bidding bottom management authority, a national level administrator is responsible for managing the related network entry, release and modification auditing work of the bidding documents of a bidding primary level, a provincial level administrator is responsible for managing the related network entry, release and modification auditing work of the bidding documents of a bidding secondary level, a municipal level administrator is responsible for managing the related network entry, release and modification auditing work of the bidding documents of a bidding primary level and a bidding secondary level, the ordinary users are responsible for uploading, modifying and issuing expert review opinions of specific benchmarks.

The bidding four-stage system is divided into four stages according to the size of the bidding base,

the first level is that the bid price is larger than 10 hundred million RMB;

the second level is that the bid price is larger than 5000 ten thousand yuan and less than 10 hundred million;

the third level is that the bid price is more than 5 ten thousand yuan and less than 5000 ten thousand yuan;

the fourth grade is that the bidding bid is more than 5 thousand yuan and less than 5 ten thousand yuan.

The bid base less than 5000 yuan is not included in the bid system.

It should be noted that the bid amount here is only a range value, and is not a specific bid amount, for example, the bid amount is a first-level bid, and it is noted that the bid amount is greater than 10 hundred million when the bid is issued, and the specific bid amount is confidential and cannot be revealed at will.

When a first-level call expert is called for bidding, the first-level call expert is randomly selected from a national expert library, the experts are divided into written bid evaluation experts and field bid evaluation experts, field bid evaluation is carried out after the written bid evaluation experts pass, and the written bid evaluation experts uniformly evaluate bids in a national-level public resource trading platform center;

when the second-level bid inviting and bidding invoking experts are called, the experts in the city and place where the bidding inviting and bidding units reside are not required to be invoked and randomly selected from the provincial expert base, the experts are divided into written bid evaluation experts and field bid evaluation experts, the field bid evaluation is carried out after the written bid evaluation experts pass, and the written bid evaluation experts carry out unified bid evaluation in the provincial public resource transaction platform center;

when the third-level bidding and bidding call experts are called, the experts in the county can not be called, the experts are randomly selected from a city expert base, the experts are divided into written bid evaluation experts and field bid evaluation experts, field bid evaluation is carried out after the written bid evaluation experts pass, and the written bid evaluation experts uniformly evaluate bids in a city-level public resource trading platform center;

when a fourth-level call expert is bid, the county expert is called and randomly selected from a county expert library, the experts are divided into written bid evaluation experts and field bid evaluation experts, field bid evaluation is carried out after the written bid evaluation experts pass, and the written bid evaluation experts uniformly evaluate bids in a city-level public resource transaction platform center;

it should be noted that the bid of the present application is divided according to the bid base amount or the bid budget amount, and the specific use of the bid proposal is irrelevant to the administrative level of the bid unit itself.

The state level refers to state ministry, central government and department, provincial level refers to provincial administrative districts, city level refers to regional administrative districts, county level refers to county administrative districts,

and (3) registration of bid evaluation experts:

after the experts of each region are preliminarily screened by expert management units of each region, the experts self-declare at the expert end, including registering user names and setting passwords, after the registration is successful, the specific filled items are filled and reported by each region according to conditions, the filled and reported contents at least need to include the expert identity card numbers, the units of the profession, the field where the expert is located, recent non-crown photos and contact mobile phone numbers, after the experts self-declare, after the expert management unit end is approved and approved, the experts become evaluation experts of the expert management unit, before the expert management unit end is approved and approved or requires the expert to declare that the expert requires to provide relevant data of the real name system, before the expert fails to provide effective data, the expert cannot become the evaluation expert of the expert management unit, and the contact mobile phone numbers need to be mobile phone numbers of the experts authenticated by the real name system.

The tenderer end can only be a unit user, submits a tendering scheme after registering a user name and setting a password, and the tendering scheme is issued on a public resource transaction platform management system after being approved and approved by a tendering and bidding management unit.

After the bidder registers the user name and sets the password, the bidder clicks the effective bidding scheme to submit the bidding scheme, and the bidding scheme is recorded on the background of the public resource transaction platform management system without being checked and approved by the bidding management unit.

According to the specification of the bidding documents, 293 prefecture cities exist in the whole country, so that the bidding documents adopt a prefecture city code + bidding date code + sequence code, for example, because 293 prefecture cities exist in the whole country, the prefecture city code is 3 bits, the date code is 8 bits, the sequence code is 3 bits, one bidding is performed on 3 month and 18 days in 2019 in Changde City, on the day of 3 month and 18 days, the bidding is 57 th, and the region code of the Changde City is 253, so that the bidding code at this time is 253-20190318-057, the Beijing city code is defined as 001, other province cities are respectively defined as 002 to 031, no hong Kong platform is included, the vacancy is from 040 to 039, the region code of a non-province city is calculated from 040, so that the first 3 bits are the prefecture city of first stage, the bidding number from 002 to 031 is the bidding stage number of first stage, the bidding documents from third stage and the bidding, so that all the bidding documents are searched for the bidding documents of the prefecture documents of the first stage, the fourth stage 057-057, and the searching of the bidding documents of the third stage 057-year is started, and the searching of the bidding documents is called document 057-057.

Determining and opening the source base amount, wherein the determination of the source base amount is an important ring, and the following steps are adopted for determining the source base amount:

1, the organization personnel of the bidding unit carries out the project site survey, analyzes the factors influencing the price of the bidding base as much as possible, records the factors into the analysis book of the bidding base and provides specific data parameters as much as possible.

And 2, determining the main bid amount, primarily determining the bid amount by the bidding unit, wherein the bid amount is the main bid amount, reporting to a main department of the bidding unit for record, and uploading the main bid amount to the server by the bidding unit, but the main bid amount is not public.

3. After the bidding unit uploads the main bid amount, the number of bid evaluation experts and bid evaluation time need to be determined.

4. And (4) respectively and independently determining the bid amount according to the bid amount analysis book by the bid evaluation expert at the bid evaluation time, namely determining the bid amount as the bid amount of the guest.

5. And uploading the amount of the bid base of the guest to a public resource transaction platform management system by the bid evaluation expert, and processing by the system according to the following mode.

6, determining the source bid amount according to the following principle:

6.1, the principal bidding fund amount is more than 200% of the maximum value of the guest bidding fund amount, or the principal bidding fund amount is less than 30% of the minimum value of the guest bidding fund amount, the bidding activity is terminated, and the bidding unit needs to determine the source bidding fund amount additionally.

6.2, the main bid amount is less than 200% of the maximum value of the guest bid amount, and the main bid amount is greater than 30% of the minimum value of the guest bid amount, then the average amount of the bid amounts of all the bid evaluation experts is the source bid amount, for the subsequent work, the final value of the source bid amount is an integer value close to the calculated value, for example, an integer value such as 8100 ten thousand and 8200 ten thousand,

and 7, the main encryption standard base and the auxiliary encryption standard base, after the source standard base amount is obtained, the system generates a main salt value and an auxiliary salt value, and the main salt value and the auxiliary salt value are used for respectively encrypting the source standard base amount, so that the main encryption standard base and the auxiliary encryption standard base are respectively obtained.

8, deleting the source base amount, after obtaining the main encryption base and the auxiliary encryption base, deleting the source base amount by the public resource transaction platform management system,

and 9, sending the main salt value and the auxiliary salt value, sending the main salt value to a mobile phone of a guest bid evaluation expert randomly selected by the system, sending the auxiliary salt value to a mobile phone of a responsible person, and disclosing the mobile phone number of a main salt value keeper after changing the number, wherein the number after changing the number can only be called through by the number of the responsible person and is published on a public resource transaction platform management system, and the number is recorded as a bid removal number.

10. Deleting the main salt value and the auxiliary salt value, and after sending, deleting the main salt value and the auxiliary salt value by the public resource trading platform management system;

11. and determining the bid opening time, determining the bid opening time by the bid inviting unit, and submitting the specific bid opening time to a public resource trading platform management system.

12. In the first two hours of the opening time, the public resource transaction platform management system discloses the main encryption standard bottom and the auxiliary encryption standard bottom, and only the main encryption standard bottom and the auxiliary encryption standard bottom are disclosed in the first two hours of the opening time, so as to prevent premature disclosure, cause hacker cracking, have short time and low possibility of hacker cracking,

13. opening bid, the bid document does not record the bid amount, after the bidding unit submits the bidding document, the bidding unit enters the opening bid stage, opening bid is informed, the whole course is recorded, each bidding unit enters the bidding writing chamber in sequence, after the bid amount is written, the bidding amount is sealed or covered, the bidding unit leaves the bidding writing chamber, the next bidding unit enters the bidding writing chamber, until all the bidding units write the bid, the host declares opening bid, all the bidding units lift the label, tear off the seal or the cover, the host records the bid amount of each bidding unit in public, after the correctness is confirmed, the bidding unit enters the opening bid stage.

14, when the source bid-under amount is cancelled, the value range of the integer value of the source bid-under amount must be the same as the programming rule when the value of the source bid-under amount is determined, for example, when the source bid-under amount is 100 ten thousand, the source bid-under amount is cancelled, 100 ten thousand is used for increasing or decreasing, when the source bid-under amount is 50 ten thousand, and if the source bid-under amount is 100 ten thousand, the source bid-under amount cannot be cancelled.

14.1, decrypting by using the main salt value, dialing the label-removing number by a responsible person, submitting the main salt value to the public resource transaction platform management system by a label-removing number holder, and removing labels according to the following method, wherein attention must be paid to label-removing time, and since the main encryption standard base and the auxiliary encryption standard base are disclosed two hours before label-removing, the label-removing time is calculated from time, and since the label-removing method needs a certain time, the system is set within three hours of the disclosure of the main encryption standard base and the auxiliary encryption standard base, and the label-removing cannot be removed even if the main salt value data is uploaded, so that a keeper of the main salt value data does not have any use even if the keeper wants to remove labels in advance.

The public resource transaction platform management system starts to decrypt by using main underlying amount as a base value and by adopting an up-tracing and down-tracing mode, in a programming rule, an integer value range and a value rule of the underlying amount need to be marked, for example, values are taken at the frequency of 100 ten thousand yuan, if the underlying amount of a current bidding unit is 7500 ten thousand yuan, the upper limit is 150% of the main underlying amount which is smaller than the highest value of the guest underlying amount, and the lower limit is 50% of the main underlying amount which is larger than the lowest value of the guest underlying amount, namely the upper limit is 11300 ten thousand yuan, the lower limit is 3800 ten thousand yuan, the upper limit is increased or decreased at the frequency of 100 ten thousand, for example, encryption is started by using 3800 ten thousand yuan and main salt value data as original data, and the result is inconsistent, encryption is started from 3900 ten thousand yuan and main salt value data as the original data until 11300 ten thousand yuan, and if the final result of encryption and the main underlying amount displayed by the public resource transaction platform management system are the same, the underlying amount used for encrypting is the current underlying amount.

14.1, decrypting by using the auxiliary salt value, dialing the label-removing number by a responsible person, starting label-removing of the auxiliary salt value after a label-removing number holder submits a request which can not provide the main salt value to the public resource transaction platform management system, removing the label according to the following method,

the public resource transaction platform management system starts to decrypt by using the sub-salt data by adopting an up-tracing and down-tracing mode by taking the main bid amount as a base value, and in a programming rule, an integer value range and a value rule of the main bid amount need to be marked, for example, values are taken at a frequency of 100 ten thousand yuan, if the bid amount of a bid unit is 7500 ten thousand yuan at present, the upper limit is 11300 ten thousand yuan and the lower limit is 3800 ten thousand yuan according to the condition that the main bid amount is smaller than 150% of the highest value of the guest bid amount, and the main bid amount is larger than 50% of the lowest value of the guest bid amount, the upper limit is 11300 ten thousand yuan and the lower limit is 3800 ten thousand yuan, the encryption is gradually increased or decreased at a frequency of 100 ten thousand, for example, the encryption is started by taking 3800 ten thousand yuan and the sub-salt data as original data, and the result is inconsistent, the encryption is started from taking 3900 ten thousand yuan and the sub-salt data as the original data until 11300 ten thousand yuan, and if the final result of the encryption is the same as the sub-bid amount displayed by the sub-base value displayed by the public resource transaction platform management system, and the source bid amount used for encrypting is the current source bid amount.

15. And (4) directly declaring the bid amount which is lower than the source bid amount, and entering the next bid evaluation stage if the bid amount is more than or equal to the source bid amount.

The following terms are defined as follows:

noun 1, person in charge: the number-changing software automatically changes the number by the number of one person of the bidding unit and sends the number-changing number of the bid evaluation expert to the mobile phone of the person, and the person is the responsible person, and in the whole bidding activity, the bid evaluation expert can only communicate with the responsible person.

Noun 2, main bid evaluation expert, which is the bid evaluation expert of the bidding organization.

Noun 3, the subject evaluation expert, which refers to the evaluation expert of non-bidding units.

Noun 4, main bid amount, which is the total bid amount determined by the bidding unit.

Noun 5, amount of the bid-price, the amount of the bid-price is the total amount of the bid-price determined by the bid evaluation expert of the guest, one bid-calling file only has one amount of the host bid-price and N amounts of the bid-price, and N is two or more.

Noun 6, source bid amount, value of source bid amount = (main bid amount + guest bid amount)/number of bid evaluation experts, the result is a non-integer value, and then an integer value is determined through a programming rule.

Noun 7, main encryption standard base, source standard base amount is encrypted by two random salt value data, the salt value data is mastered by an expert in the special guest evaluation target, the source standard base amount encrypted by the salt value data is the main encryption standard base, and the expert bidding target is randomly selected by the system in the special guest evaluation target.

Noun 8, sub-encryption bid base, source bid base amount is encrypted by two random salt value data, the salt value data is grasped by a bidding unit or a competent department of the bidding unit, and the source bid base amount encrypted by the salt value data is the sub-encryption bid base.

Noun 9, guest enciphering standard base, enciphering the sum of guest standard base with salt value data, and when evaluating total standard base sum, the evaluation expert displays the guest enciphering standard base on the standard base evaluation book, and the management system of the public resource transaction platform uploads the sum of guest standard base,

since the evaluation expert normally evaluates an integer value, the system is required to generate a random value, for example, the evaluation expert evaluates 8100 ten thousand, and after the random processing, the evaluation expert evaluates 81035479 which is close to 8100 ten thousand, the 81035479 is encrypted, but the guest encryption bid base of the bid base evaluation book is not sent to the bidding institution, but is saved by the evaluation expert, when the system is restored, the public resource transaction platform management system uses the guest encryption bid base provided by the evaluation expert, uses the amount of the guest bid base displayed on the public resource transaction platform management system to encrypt MD5 according to the close value until the guest encryption bid base provided by the evaluation expert is matched, when the restoration process is performed, a random value range needs to be defined, for example, the random value is not more than 100 ten thousand, in this example, all numbers between 81000000 and 81100000 are defined, the maximum number of restoration is 100 ten thousand, which is mainly to prevent part of the bid evaluation experts from disorderly reviewing the bid base, for example, the host bid base is 9000, and as a result, when the system is designed, other ad users can easily review the system can easily find out the abnormal evaluation base, and the system can easily find out the application.

Noun 10, main salt value, and the salt value data used by the main encryption standard is the main salt value.

Noun 11, sub-salt value, and sub-salt value data used by the sub-encrypted standard base is the sub-salt value.

According to the scheme, the tender unit personnel or the supervisor unit personnel can decrypt the salt data by using the auxiliary salt data mastered by the tender unit personnel or the supervisor unit personnel only under the condition that the main salt data cannot be provided, namely the authorization of the main salt data keeper is actually needed, so that the main salt data keeper loses the salt data and the loss of the mobile phone is very likely to happen.

In addition, in government procurement, a bid control price is provided, and the bid control price is relatively transparent to a bidding base, so that the advantage is achieved, but the defect is obvious, that is, some bidding units have bid accompanying units, even the bidding units and the bidding units are communicated in a collective mode, the bid price is raised, the bid control price is already disclosed, the problem of losing bid guarantee money does not exist, and the bid accompanying units usually take the upper limit of the bid control price as a standard to raise the bid price, so that a successful bid owner can bid at a higher price, and the advantage of the medium and small sized items adopting the bid control price is obvious, but a large item adopting the bid control price is difficult to avoid various problems.

Evaluating the bid according to the following steps,

step 1, after bidding is opened, the public resource trading platform management system determines bid evaluation time and bid evaluation experts, when the bid evaluation experts are determined, a bidding unit is required to specify the number of the bid evaluation experts and the types of the bid evaluation experts, and the public resource trading platform management system matches the relevant bid evaluation experts according to the requirements of the bidding unit.

And 2, compiling detailed operable bid evaluation standards for bid inviting files so as to prepare bid evaluation experts as bid evaluation bases.

And 3, each bid evaluation expert independently evaluates the bid, and for both the bid-winning unit and the selection-falling unit, the bid-winning reason and the selection-falling reason are marked.

And 4, in the bid evaluation process, the bid evaluation computer cannot install software with personal communication, such as WeChat and QQ.

And 5, the bid evaluation expert uses a computer to inquire data through internet surfing, the public resource transaction platform management system program captures the address of the webpage and records the browsing time of the webpage, and the address of the webpage and the browsing time are recorded as one of bid evaluation contents.

Step 6, evidence of the bid evaluation process is retained, the evidence of the bid evaluation process comprises video evidence, audio evidence and picture evidence, if a large amount of video evidence is stored, the data volume is increased, therefore, the video evidence often has a certain retention period, however, a bidding project generally takes a long time and often reaches several years, the project is not completed, the related video evidence of the bidding activity does not exist, once disputes occur, the truth is difficult to clear, the picture evidence has the defects of easy copying and modification, the legal effectiveness of the evidence often has problems, accordingly, spliced pictures are adopted for preventing modification, the principle of the spliced pictures is that pictures are used as evidence in key steps of the bidding activity to ensure the fairness of the pictures, for example, pictures when bidding units lift the boards during bid opening, two cutting keys are that the bid amount cannot be modified at will, the head modification difficulty of the participants is large, the heads of the participants and original bid originals are printed by the bidding units, and the original bidding units are difficult to modify, and the participants can hardly use in common transaction management of the bidding units.

And 7, communicating the bid evaluation expert with the bidding unit and the bidding unit personnel, wherein the public resource transaction platform management system adopts voice-changing software during communication, so that the bidding unit and the bidding unit personnel are not clear of specific dialogue with the bid evaluation expert during communication.

Step 8, evaluating a bidding conclusion and signing, wherein the bidding conclusion is divided into 3 parts, a source conclusion, an encryption conclusion and salt value data,

and 8.1, source conclusion, namely directly uploading the bid evaluation conclusion to a public resource transaction platform management system after the bid evaluation expert finishes bid evaluation, wherein the source conclusion is called source conclusion.

And 8.2, encrypting the conclusion, wherein the data of the source conclusion part reserved by the bidding unit is formed by encryption, so the result is called an encrypted conclusion.

And 8.3, the salt data is auxiliary encrypted data which is saved by the evaluation expert and is used in the encryption process of the source conclusion part data, so that the salt data is called as the salt data.

The embodiment is as follows: the encryption flow of the encryption conclusion is carried out,

step 1, the system firstly stipulates that the bid evaluation conclusion of the bid evaluation expert has the lowest word number limit, for example, the lowest 300 words.

And 2, grouping the bid evaluation conclusions by the system according to a certain word number, for example, dividing the bid evaluation conclusions into groups of 6 words, wherein the bid evaluation conclusions have at least 50 groups according to the specification of the first step, and counting the groups by the system.

And step 3, determining the initial group number and the encryption group number for starting encryption, wherein the group number calculation is performed in a reverse order from the text tail of the bid evaluation conclusion, namely the text tail is the 1 st group, the initial part is the last group, and the encryption group number is not more than the number of the divided groups, otherwise, the program calculation is in error.

Step 4, allocating the salt value data of the corresponding group number according to the group number required to be encrypted, and encrypting the salt value data in groups,

there are many methods for the number of encryption groups, one is to use a randomly generated data to control, for example, randomly generate 8, or 8 groups, randomly generate 7, or 7 groups, and add the random number as salt data into salt data of an evaluation expert, one is to uniformly specify, for example, uniformly specify 8 groups, all encryption conclusions are composed of 8 groups, for example, if MD5 of 32-bit data type is used for encryption, then MD5 of 32-bit data type has a data length of 16 bits, therefore, all encryption conclusions are 16 × 8=128 bits, if random data is used, the encryption conclusion is not the same, but the length of the encryption conclusion is not related to the length of the source conclusion, so that although the source conclusion is public, the length of the encryption conclusion cannot be analyzed.

And 5, decrypting, namely when decryption is needed, providing the salt value data by the bid evaluation expert, encrypting by using the source conclusion, and decrypting if the encryption conclusion is consistent with the encryption conclusion of the bidding unit.

Signature processing, wherein the signature is encrypted by MD5, the specific steps are that the name of the evaluation expert and salt value data are encrypted to obtain an MD5 value after encryption, then the evaluation expert writes the MD5 value, it needs to be noted that handwriting recognition software is adopted for the MD5 value written by the evaluation expert, namely the evaluation expert needs to scan the MD5 value written by the evaluation expert into the public resource transaction platform management system software, the handwriting recognition software is adopted, only if the MD5 value recognized by the handwriting is the same as the encrypted MD5 value, the manual signature can be successful, if the evaluation expert has errors in handwriting for the first time, the original signature must be scratched, and the signature is carried out again until the signature is correct.

Because the signature is an encrypted signature, when a specific bid evaluation expert needs to be identified, two methods are provided, one is handwriting identification, the bid evaluation expert of the project is inquired through a public resource transaction platform management system, handwriting comparison is utilized, the other method is decryption by utilizing MD5, and the method needs to be noted that the value range of the randomly generated salt value data needs to be limited, for example, 6 numbers from 0 to 9, so that the decryption is simpler, the salt value data is enumerated and cracked from 000000 to 999999 by directly utilizing all expert names participating in the bid evaluation project, and cracking software is faster.

Communication between the bidding institution and the bid evaluation expert:

the bidding unit and the bid evaluation expert are communicated by adopting number-changing software, and the number-changing software is completed by adopting the following steps:

step 2, the number changing software changes the mobile phone numbers of all the bid evaluation experts, and changes the number of the mobile phone number of one person of the bid inviting unit, wherein the person of the bid inviting unit is called a responsible person, and then the public resource transaction platform management system sends the number changing number to the mobile phones of the responsible person and the bid evaluation experts;

step 6, after the number change is completed, when a responsible person and a bid evaluation expert use a mobile phone to communicate, two schemes are provided, wherein the two schemes are as follows:

step 6.1, noise appears after the communication, so that the communication cannot be clearly heard, the opposite party can only be informed of the message, and the information expression of the two parties is carried out through short messages;

The bidding expert is forbidden to use voice communication with the bidding unit because the bidding expert is used to listen to the surnames of other people according to the traditional Chinese habits to call the other people so as to be beneficial to calling the other people, in addition, the possibility of disclosing various information by the bidding expert is very high in voice communication, if short messages are used, the possibility of disclosing the information is very low, both people can not know the information of the other people through changing the number, the possibility of sleeving is lower, the bidding unit only uses the responsible person to contact with the bidding expert, if the situation that the situation does not accord with the legal regulations occurs, the responsible person of the bidding unit has irrevocable responsibility, at least, the original information at first is disclosed by the responsible person, the responsibility of the responsible person is stronger, in addition, the short messages have the characteristics that the text content is not similar to the voice content, the text content is easy to inquire, if the person of the bidding unit knows the contact way of the bidding expert and can be connected with the text expert, and the problem is not good source.

And then entering a final bid stage, downloading a bid evaluation conclusion by a bidding organization, and determining a preliminary bid winner according to the bid evaluation decision.

And (4) performing field assessment, wherein after the written assessment is passed, the preliminary bidding wining unit is informed to perform field assessment, however, the written assessment conclusion is published after the field assessment, if the written assessment conclusion is far from the field assessment conclusion, the written assessment conclusion needs to be rechecked, and if the field assessment and the written assessment conclusion are approximately consistent, the written bidding wining unit becomes a formal bidding winner.

After the bid settling and the field examination pass, the contract is signed, and the bidding process is completed.

the encryption flow of the encryption conclusion and the salt data is as follows:

step 1, the management system of the public resource transaction platform provides that the bid evaluation conclusion of the bid evaluation expert has the lowest word number limit, and the bid evaluation conclusion can be successfully submitted only under the condition that the word number is equal to or exceeds the lowest word number;

step 3, determining the initial group number and the encryption group number for starting encryption, wherein the encryption group number is less than the number of the divided groups, and the public resource transaction platform management system automatically generates the definition values of the initial group number and the encryption group number for defining the initial group number and the encryption group number for encryption;

and 5, when decryption is needed, the salt value data is needed to be provided by the bid evaluation expert, encryption is carried out by utilizing the source conclusion, and the obtained encryption conclusion is consistent with the encryption conclusion of the bidding unit, namely decryption is carried out.

2. The common resource trading platform management system of claim 1, wherein: the label opening step is as follows:

step 1, determining the bid opening time by a bid inviting unit, and submitting the specific bid opening time to a public resource transaction platform management system;

step 3, opening the bid, wherein the bid document does not record the bid amount, the bidding unit enters the opening stage after submitting the bidding document, the opening discipline is informed when opening the bid, the whole course of the opening chamber is recorded, each bidding unit sequentially enters the bidding writing chamber, the bidding writing chamber is not recorded, after the bid amount is written, the bid amount is sealed or covered, the bidding unit is taken out of the bidding writing chamber and enters the next bidding unit, until all the bidding units finish writing the bid, the host announces opening the bid, all the bidding units lift the label, tear off the seal or the covering object, the host publicly records the bid amount of each bidding unit, and after confirming that no bid exists, the opening stage is entered;

step 4.1, decrypting by using the auxiliary salt value, dialing the label-removing number by a responsible person, starting label-removing of the auxiliary salt value after a label-removing number holder submits a request which can not provide the main salt value to the public resource transaction platform management system, and removing the label according to the following method,

and 5, directly declaring the outgoing if the bid amount is lower than the source bid amount, and entering the next bid evaluation stage if the bid amount is more than or equal to the source bid amount.

3. The common resource trading platform management system of claim 1, wherein: signature processing, wherein the signature adopts MD5 encryption, the specific steps are,

step 2, the evaluation expert manually writes the MD5 value;

step 5, when the handwritten data identified by the public resource transaction platform management system software is different from the encrypted MD5 value, the manual signature fails; the public resource transaction platform management system software indicates the difference between the two, and the appraisal expert needs to give up the original signature according to different reasons, the handwriting is illegible, and the original signature is abandoned, and the handwriting is resubmitted after the completion, and if the handwriting is wrong, the error is corrected, the original signature is scratched, and the signature is resubmitted;

and 6, after the signature is finished, taking out the bidding documents by the bidding evaluation experts, putting the bidding documents into a bidding document temporary storage room which is not monitored until all the bidding documents are put into the bidding document temporary storage room and leave, and taking out the bidding documents by the bidding unit.

4. The common resource trading platform management system of claim 1, wherein: the standardized management of the bidding document files is realized,

the standardized management of bidding documents means that the file names of the bidding documents have public beginning parts, namely all the files of one bidding document have the same file name beginning part, and the paper files, the file folders and the electronic document names are the same.

5. The common resource trading platform management system of claim 1, wherein: the public resource transaction platform management system adopts number-changing software to facilitate the connection between a bidding unit and a bid evaluation expert, and the number-changing software is completed by adopting the following steps:

step 3, after the number change is finished, the responsible person and the evaluation expert cannot communicate by using the original number;

step 4, after the software changes the number, the mobile phone communication between the responsible person and the evaluation expert is controlled by the number-changing software, and the communication with other people is not affected;

and 7, after the bid evaluation is finished, the number change software releases the number change, at the moment, the dialed number change number is a null number, and the short message cannot be received.
