[0100] In this embodiment, characteristic analysis refers to an in-depth analysis of the characteristics of each bid evaluation indicator, including the connotation, extension, degree of difficulty in quantification, and relationship with other indicators of the indicator.

[0101] In this embodiment, the model scoring rules refer to the scoring methods and rules formulated according to the characteristics and types of the bid evaluation indicators, which define how to convert the bid evaluation indicators into specific scores and how to comprehensively consider different indicators to obtain the final scoring results.

[0102] In this embodiment, the indicator classification result refers to dividing the evaluation indicators into different categories or groups according to the analysis of their characteristics. For example, the evaluation indicators are divided into qualitative indicators and quantitative indicators. In construction evaluation, quantitative evaluation indicators may include: project quotation, construction period, and project volume; qualitative evaluation indicators: rationality of the design plan, experience and qualifications of the construction team, and quality assurance measures.

[0103] In this embodiment, the scoring criteria refer to specific standards or criteria used to evaluate the bid evaluation indicators.

[0106] Embodiment 6:

[0107] The embodiment of the present invention provides a blockchain-based intelligent bid evaluation management system, an optimization module, including:

[0108] Rating table unit: collects the rating data of all rating experts to form an expert-vector rating table;

[0109] Distribution unit: Perform distribution analysis on the scoring results to obtain the scoring distribution, set the distribution percentage range and distribution fluctuation range for the scoring distribution, obtain the high scoring vector and the low scoring vector according to the distribution percentage, and obtain the abnormal evaluation vector according to the distribution fluctuation range;

[0110] Optimization vector unit: optimizes according to the matching corresponding optimization methods of high-scoring vectors, low-scoring vectors and abnormal evaluation vectors in the expert-vector scoring table to obtain the optimization vector;

[0111] Smart contract unit: According to the elements in the optimization vector, the bid evaluation algorithm in the bid evaluation contract is optimized to obtain a smart contract.

[0112] In this embodiment, distribution analysis is a data analysis process of the scoring results, which is used to understand the distribution characteristics of the scoring data, such as the mean, median, and standard deviation of the scores; the scoring distribution is the form of the scoring result distribution, such as whether it is normally distributed, whether there is skewness, etc. For example, in construction bidding, the analysis finds that the score distribution is concentrated in a certain interval, indicating that most experts have a relatively consistent evaluation of a certain indicator of the project.

[0113] In this embodiment, the distribution percentage range is a specific percentage range for setting the score distribution, such as the top 10% and the bottom 10%. If the distribution percentage range is set and it is found that the bid price of a certain bid is in the top 10% high score segment, it may mean that its bid price is relatively high; the distribution fluctuation range is the fluctuation size of the score result, which is used to identify abnormal fluctuations in the score. For example, if the score of a certain bid on the quality control indicator fluctuates greatly, it may indicate that experts have large differences of opinion on this.

[0114] In this embodiment, the optimization method is a method for adjusting abnormal or inconsistent data in the scoring table. For example, for abnormally high scores, regression analysis may be used to adjust them to a more reasonable level.

[0115] In this embodiment, the bid evaluation algorithm is a series of rules and calculation steps used to calculate the bid evaluation results. For example, a bid evaluation algorithm may calculate a total bid evaluation score by weighting indicators such as quotation, construction period and innovation of design solution.

[0116] In this embodiment, the smart contract is a self-executing contract on the blockchain, in which the terms exist in the form of code. For example, in a construction bid, the smart contract can automatically determine the winning bid based on the bid evaluation algorithm and the bidder's data, and automatically execute the contract terms.

[0117] The working principle and beneficial effects of the above technical solution are as follows: by collecting scoring data, analyzing the distribution of scoring results, identifying abnormal scores, and then optimizing the scoring vector, the evaluation algorithm in the evaluation contract is finally adjusted to achieve more accurate and credible evaluation results, making the evaluation results more precise and reliable.

[0121] Evaluation brain formation unit: Deploy smart contracts on the blockchain structure based on the validity verification results to form an intelligent evaluation brain.

[0122] In this embodiment, a deployment transaction refers to creating a transaction on a blockchain, which contains the code and data of a smart contract, and the purpose is to deploy the smart contract on the blockchain. For example, in a construction bid evaluation, a deployment transaction may contain the smart contract code of the bid evaluation rules, which is used to execute the bid evaluation process on the blockchain.

[0123] In this embodiment, the contract code refers to the source code of the smart contract, which defines the function and logic of the smart contract. For example, in a construction bid evaluation, the contract code may include the evaluation rules, scoring criteria, weight distribution and other logic.

[0124] In this embodiment, a contract transaction refers to a transaction that includes smart contract code and data, which will be broadcast to the blockchain network and verified and executed by nodes in the network. For example, in a construction bid evaluation, a contract transaction may include the smart contract code of the bid evaluation rules, as well as related bid evaluation data and parameters.

[0125] In this embodiment, verifying the validity of a contract transaction refers to the nodes in the blockchain network verifying the validity of the contract transaction according to a consensus algorithm, including verifying the syntactic correctness of the contract code, the integrity of the transaction data, etc. For example, in a construction bid evaluation, verifying the validity of a contract transaction may include checking whether the smart contract code of the bid evaluation rules is correct, and whether the bid evaluation data is complete and accurate.

[0126] In this embodiment, broadcasting refers to sending the contract transaction to all nodes in the blockchain network for verification and execution by the nodes. For example, in construction bid evaluation, broadcasting may include sending the smart contract code of the bid evaluation rules and the bid evaluation data to all nodes in the blockchain network.

[0127] In this embodiment, forming an intelligent bidding evaluation brain means successfully deploying the smart contract on the blockchain structure based on the validity verification results, thereby forming an intelligent bidding evaluation brain. For example, in construction bidding evaluation, forming an intelligent bidding evaluation brain may include deploying a smart contract of bidding evaluation rules on the blockchain and enabling it to automatically execute the bidding evaluation process.

[0128] The working principle and beneficial effects of the above technical solution are as follows: by creating a deployment transaction, the smart contract code is deployed to the blockchain, and the validity of the transaction is verified by the consensus algorithm of the blockchain, and finally an intelligent bidding evaluation brain is formed and runs on the blockchain, ensuring the transparency and security of the bidding evaluation process, thereby increasing the transparency and credibility of the bidding evaluation process.

[0129] Embodiment 8:

[0130] The embodiment of the present invention provides a blockchain-based intelligent bid evaluation management system, wherein the bid evaluation brain forming unit includes:

[0131] The validity verification results are packaged into a new block. After the new block is accepted by the network and added to the blockchain, the deployment transactions in the block are executed sequentially. At the same time, the bytecode of the smart contract is recorded on the blockchain, and the contract address is generated, thus forming an intelligent bidding brain.

[0132] In this embodiment, a new block is a data structure in a blockchain network, which contains a set of transaction records and is created at regular intervals and appended to the end of the blockchain. A new block usually includes a block header and one or more transaction records. The block header contains metadata of the block, such as version number, hash value of the previous block, timestamp, difficulty target, random number, etc. For example, in a construction bid, suppose there is a bidding process that needs to be evaluated through a smart contract. When the relevant information of the bid evaluation (such as the validity verification result) is verified to be correct, this information will be packaged into a new block. A new block may contain all the scoring records of a certain construction bid.

[0133] In this embodiment, bytecode is a low-level code, which is a binary representation of the compiled smart contract source code. It consists of a series of bytes and can be understood and executed by blockchain nodes. It includes all the operation instructions of the smart contract. These instructions define the logic and behavior of the contract. For example, in the example of construction bidding, the bytecode of the smart contract may represent the evaluation rules, such as how to calculate the total score, how to determine whether the bid is valid, etc. After these rules are compiled into bytecode, they are stored on the blockchain.

[0134] In this embodiment, the contract address is a unique identifier of the smart contract on the blockchain. Once the smart contract is deployed, a unique contract address will be generated. The contract address is usually generated by the hash value of the public key, which ensures the uniqueness of the address. For example, for a construction bid, once the bid evaluation smart contract is deployed on the blockchain, it will generate a contract address. All companies participating in the bid can view the bid evaluation results or interact with the smart contract through this contract address.

[0135] The working principle and beneficial effects of the above technical solution are as follows: by packaging the validity verification results into a new block and adding it to the blockchain, executing the deployment transaction, recording the smart contract bytecode, and generating the contract address, an intelligent bidding evaluation brain is constructed to ensure the security and immutability of the bidding evaluation data.

[0136] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
