Description

Technical Field

[0001] This invention relates to the field of evaluation of power bidding documents, and specifically to a method for evaluating the technical content of power bidding documents. Background Technology

[0002] In the field of power engineering, the evaluation of bidding documents, especially the evaluation of technical content, is crucial. Traditional manual evaluation methods suffer from numerous drawbacks, including low efficiency, high error rates, and heavy workload, making them unsuitable for the demands of modern power engineering bidding. Therefore, the construction of intelligent bidding assistance platforms has become an inevitable trend. Leveraging technologies such as text parsing, intelligent document comparison, and intelligent document review, these platforms can assist bidding experts in quickly completing their evaluations. This not only reduces evaluation time and workload but also lowers the error rate and improves the quality of evaluations. Furthermore, it minimizes human intervention, further ensuring the fairness and impartiality of the bidding process.

[0003] Although existing technologies for intelligent identification and evaluation of power bidding documents have made some progress, there are still some shortcomings in practical applications.

[0004] For example, the existing Chinese patent with authorization announcement number CN108021543B discloses an Internet+-based power equipment procurement system, including a database package with text tags and electronic tags. The text tags carry the name of the power equipment corresponding to the name of the power equipment carried on the text tag, and the electronic tags carry information about the power equipment; a reader that identifies the information of the power equipment to be procured through radio frequency technology; an automatic tender document generation system that automatically generates tender documents based on the information of the power equipment to be procured transmitted by the reader; an automatic bid evaluation system that automatically evaluates the bid documents uploaded based on the tender documents and selects suitable bid documents to generate a bid evaluation report; and a smart dongle module that encrypts the tender documents and bid evaluation reports in the automatic bid evaluation system to prevent modification.

[0005] Although the aforementioned patent has an automatic bid evaluation function, it has obvious defects: on the one hand, it does not elaborate on the specific operation process of automatic bid evaluation; on the other hand, the evaluation dimension is singular, and it only judges based on the comparison results of the main performance index data of the bid and the data required by the bid opening standard, without considering factors such as safety regulations, so the evaluation system is not perfect and is not conducive to selecting the best bid. Summary of the Invention

[0006] The technical problem to be solved by this invention is that it proposes a method for evaluating the technical content of power bidding documents, in order to address the shortcomings of existing technologies. On the one hand, it does not elaborate on the specific operation process of automatic bid evaluation; on the other hand, the evaluation dimensions are too simplistic, relying solely on the comparison results of the main performance indicators of the bid documents with the data required by the bid opening standards, without considering factors such as safety regulations, resulting in an imperfect evaluation system that is not conducive to selecting the best bid documents.

[0007] The technical solution of this invention is: A method for evaluating the technical content of power bidding documents includes the following steps: S1. Extract the bidding documents and each bid document from the bidding platform, and obtain the technical content of each bid document through electronic document parsing; S2. Extract the construction safety specification section from the technical section of each tender document, determine whether it contains the necessary modules and whether each sub-item of the necessary modules complies with the safety specification standards, and evaluate the safety specification compliance of each tender document. S3. Based on the assessment results of the safety compliance of each tender document, the qualified tender documents are initially selected. S4. Extract the equipment and material technical parameters section from the technical content of each qualified bid document in the preliminary screening, obtain the technical parameters of the core equipment, materials and accessories, compare them with the corresponding technical parameter requirements in the bidding documents, evaluate the technical parameter compliance score of each bid document and generate a ranking.

[0008] The specific analysis process of step S1 is as follows: Extract the power bidding documents from the bidding platform, and extract the bid documents from each bidding manufacturer, and record them as each bid document; Obtain the tender document's specifications for the bid document format. If it is a mandatory uniform format, extract the title words for the technical section of the bid document from the tender document's format specifications. If it is a self-designed format, extract the set of title words for the technical section of the bid document from the database. Traverse each tender document, retrieve the title words of the technical section, and mark the position of the title words as the starting position of the technical section; Obtain the level of the title words of the technical section in each tender document, retrieve the next adjacent title word with the same level as the title word of the technical section, and mark the position of the title word as the end position of the technical section content; Extract the technical content of each bid document based on the start and end positions of the technical section.

[0009] The specific analysis process of step S2 is as follows: Obtain the title keywords for the construction safety specifications section, and extract the content of the construction safety specifications section from the technical section of each tender document; If the construction safety specifications section of the tender documents meets all the following conditions, then the tender documents comply with the safety specifications. (1) Includes all necessary modules; (2) All sub-items of each necessary module comply with safety standards and specifications; Conversely, the tender documents do not meet safety standards.

[0010] The specific method for determining whether the construction safety specification section contains all necessary modules is as follows: Obtain the tender documents and their specifications regarding the format and content of the bid documents; If a uniform format is mandatory, each module of the construction safety specifications section in the tender documents shall be designated as a necessary module and the title words of each necessary module shall be obtained. If it is a self-designed format, extract the necessary modules of the construction safety specification section and the set of title words for each necessary module from the database; The process involves iterating through the construction safety specifications section of the tender documents and searching for the title keywords of each necessary module. If all title keywords for each necessary module are successfully retrieved, then the construction safety specifications section contains all necessary modules. If the title keyword retrieval for a necessary module fails, then a necessary module is missing from the construction safety specifications section.

[0011] The specific method for determining whether each sub-item of the necessary module complies with safety standards is as follows: Obtain the safety specifications and standards for each sub-item in the necessary module, and compare the safety specifications of each sub-item in the necessary module with their corresponding standards. If the safety specifications of each sub-item in the necessary module are not lower than their corresponding standards, then each sub-item in the necessary module complies with the safety specifications and standards; otherwise, there are sub-items in the necessary module that do not comply with the safety specifications and standards.

[0012] The specific method for obtaining the safety specifications and standards of each sub-item in the necessary modules is as follows: T1: Obtain the security specifications and standards in the tender documents, and determine whether each sub-item in the necessary modules falls within the security specifications and standards in the tender documents; If a sub-item of a necessary module falls within the safety specifications and standards outlined in the tender documents, then execute T2; If a sub-item of a necessary module is not within the safety specifications and standards outlined in the tender documents, then execute T3; T2: Obtain the mandatory safety standards for the power industry for this sub-item of the necessary module and compare them with the safety standards in the tender document; If the safety specification standard in the bidding document is higher than or equal to the mandatory safety specification standard in the power industry, then the safety specification standard in the bidding document shall be used as the safety specification standard for this sub-item of the necessary module. If the safety standards in the tender documents are lower than the mandatory safety standards of the power industry, then the mandatory safety standards of the power industry will be used as the safety standards for this sub-item of the necessary module. T3: Extract the safety standards of each historical project stored in the database, and take the safety standards of the necessary module for this sub-item in the same type of historical project as the project in the tender document as the safety standards of the necessary module for this sub-item; T4: Obtain the safety specifications and standards for each sub-item in the necessary modules.

[0013] The specific analysis process in step S4 includes: Obtain the title keywords for the equipment and materials technical parameters section, and extract the content of the equipment and materials technical parameters section from the technical sections of the preliminarily qualified tender documents; Based on the equipment and material technical parameters section of each tender document, obtain the technical parameters of each core piece of equipment in each tender document and compare them with the corresponding technical parameter requirements in the tender document to analyze the compliance of each core piece of equipment in each tender document. The weights of each core device and the weights of each technical parameter in each core device are set. Based on the compliance of each technical parameter of each core device in each bid document, the compliance of the technical parameters of the core devices in each bid document is obtained through weighted fusion analysis.

[0014] The specific analysis method for the compliance of the technical parameters is as follows: D1: Obtain the type of technical parameter. If it is numeric, execute D2; if it is non-numeric, execute D3. D2: The deviation of the technical parameters is calculated by subtracting the values ​​from the technical parameters required in the tender document; Obtain the linear correlation type between technical parameters and the degree of conformity between technical parameters, wherein the linear correlation type includes positive correlation and negative correlation; Based on the quantitative mapping relationship between the set technical parameter deviation, linear correlation type and technical parameter compliance, the compliance of the technical parameters is matched to obtain the compliance. D3: Compare the technical parameters with the descriptions in the technical parameter requirements of the tender document. If the descriptions are consistent, obtain the compliance degree of the technical parameters based on the set compliance degree of the consistent descriptions. If the descriptions are inconsistent, the technical parameter compliance rate is obtained by filtering based on the set technical parameter compliance rate corresponding to various descriptions when the descriptions are inconsistent.

[0015] The specific analysis process in step S4 also includes: Similarly, based on the analysis method of the compliance of the technical parameters of the core equipment in each tender document, the compliance of the technical parameters of the materials and accessories in each tender document is obtained; The technical parameter compliance of the core equipment, materials and accessories in each bid document is substituted into a preset compliance scoring model to obtain the technical parameter compliance score of each bid document. The model includes the correlation between the technical parameter compliance of the core equipment, materials and accessories and the technical parameter compliance score.

[0016] The specific analysis process in step S4 also includes: The bid documents are sorted in descending order of their technical parameter compliance scores to generate a ranking of each bid document, which is then sent to the bidding platform.

[0017] The beneficial effects of this invention are: Compared with existing technologies, the technical content evaluation method for power bidding documents described in this invention has the following advantages: 1. Clear evaluation process: This invention details the complete operation process from extracting documents and parsing content to assessing compliance with safety standards, comparing technical parameters, analyzing technical parameter compliance scores, and generating rankings, making the evaluation process operable and traceable.

[0018] 2. Comprehensive evaluation system: This invention not only considers the compliance of equipment and material technical parameters, but also focuses on evaluating the construction safety specifications section to determine whether it includes the necessary modules and whether each sub-item of the necessary modules meets the safety specifications. It evaluates from both safety and quality dimensions to ensure that the selected tender documents are more reliable.

[0019] 3. Adaptable to different file formats: This invention addresses the different situations where the tender document format is either mandatory or self-designed. It extracts relevant title words from the tender document specifications or databases to accurately extract the technical content and content of each section, thereby improving the applicability of the method.

[0020] 4. Reasonable Compliance Calculation: When analyzing the compliance of technical parameters, this invention distinguishes between numerical and non-numerical parameters and processes them differently. For numerical parameters, the deviation is calculated by subtraction and the mapping is quantified by combining linear correlation types. For non-numerical parameters, the compliance is determined by comparison of descriptions. At the same time, weights and scoring models are considered to make the evaluation of the compliance score of technical parameters more scientific.

[0021] This addresses the shortcomings of existing technologies, such as: firstly, the lack of detailed explanation of the specific operational procedures for automatic bid evaluation; and secondly, the single evaluation dimension, which relies solely on the comparison of key performance indicators in the bid documents with the data required by the bid opening standards, without considering factors such as safety regulations, resulting in an imperfect evaluation system that is not conducive to selecting the best bid documents.

[0025] Figure 3 This is a flowchart illustrating the process of obtaining the necessary module sub-items safety specifications and standards for this invention. Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 and Figure 2 As shown, the present invention provides a method for evaluating the technical content of power bidding documents, comprising the following steps: S1. Extract the bidding documents and each bid document from the bidding platform, and obtain the technical content of each bid document through electronic document parsing.

[0028] As a preferred option, the specific analysis process of step S1 is as follows: extract the power bidding documents from the bidding platform, and extract the bid documents of each bidding manufacturer, and record them as each bid document.

[0029] Obtain the tender document's specifications for the bid document format. If it is a mandatory uniform format, extract the title words for the technical section of the bid document from the tender document's format specifications. If it is a self-designed format, extract the set of title words for the technical section of the bid document from the database.

[0030] Iterate through each tender document, retrieve the title words of the technical section, and mark the position of the title words as the starting position of the technical section.

[0031] Obtain the level of the title words of the technical section in each tender document, retrieve the next adjacent title word with the same level as the title word of the technical section, and mark the position of the title word as the end position of the technical section.

[0032] Extract the technical content of each bid document based on the start and end positions of the technical section.

[0033] It should be noted that if the format of the tender documents is a mandatory uniform format, the titles of the technical sections of each tender document will be the same. If the format of the tender documents is a self-designed format, the titles of the technical sections of each tender document may be different, but the meanings will be similar.

[0034] It should be noted that the set of titles for the technical section of the tender documents stored in the database is based on the naming rules of the technical section titles in a large number of tender documents, and the titles in the set are synonyms or near-synonyms of each other.

[0035] In this embodiment, the present invention extracts relevant title words from the tender document specifications or databases to accurately extract the technical content and content of each section, thus improving the applicability of the method, depending on whether the tender document format is mandatory or self-designed.

[0036] It should be noted that the selection of the construction safety specifications and equipment and material technical parameters sections for evaluating the technical content of the tender documents is based on the dual logic of risk control and quality assurance throughout the entire project lifecycle. Construction safety specifications directly relate to the safety of personnel and property during project implementation, ensuring that the bidder has a sound safety management system and emergency plans, effectively mitigating the risk of construction accidents. Meanwhile, equipment and material technical parameters are the material foundation of project quality; precise parameter settings ensure that the performance of equipment and materials meets design requirements, avoiding rework and delays due to substandard quality. The combined evaluation of these two sections not only strengthens safety measures from a process management perspective but also controls the quality of the project from the source, achieving a comprehensive assessment of the project's technical feasibility and reliability, reducing potential project risks, and providing strong support for the smooth progress and delivery of the project.

[0037] S2. Extract the construction safety specifications section from the technical section of each tender document, determine whether it contains the necessary modules and whether each sub-item of the necessary modules complies with the safety specifications standards, and evaluate the safety specifications compliance of each tender document.

[0038] As a preferred option, the specific analysis process of step S2 is as follows: obtain the title words of the construction safety specification section, and extract the content of the construction safety specification section from the technical part of each tender document.

[0039] If the construction safety specifications section of the tender documents meets all the following conditions, then the tender documents comply with the safety specifications.

[0040] (1) Includes all necessary modules.

[0041] (2) All sub-items of each necessary module comply with safety standards.

[0042] Conversely, the tender documents do not meet safety standards.

[0043] It should be noted that, according to the tender document's stipulations on the tender document format, if a mandatory uniform format is required, the title words for the construction safety specifications section will be extracted from the tender document's format stipulations; if a self-designed format is required, the set of title words for the construction safety specifications section will be extracted from the database.

[0044] It should be noted that the method for extracting the construction safety specifications section from the technical section of the tender documents is based on the same principle as the method for extracting the technical section from the tender documents. When the tender documents are in a mandatory uniform format, the titles of the construction safety specifications sections in all tender documents will be the same. When the tender documents are in a self-designed format, the titles of the construction safety specifications sections in each tender document may be different, but the meanings will be similar.

[0045] As a preferred embodiment, the specific method for determining whether the construction safety specification module includes all necessary modules is as follows: Obtain the tender documents and their specifications regarding the format and content of the tender documents.

[0046] If a uniform format is mandatory, each module in the construction safety specifications section of the tender documents shall be designated as a necessary module, and the title words of each necessary module shall be obtained.

[0047] If it is a self-designed format, extract the necessary modules and title sets of the construction safety specifications section from the database.

[0048] The process involves iterating through the construction safety specifications section of the tender documents and searching for the title keywords of each necessary module. If all title keywords for each necessary module are successfully retrieved, then the construction safety specifications section contains all necessary modules. If the title keyword retrieval for a necessary module fails, then a necessary module is missing from the construction safety specifications section.

[0049] It should be noted that the necessary modules of the construction safety specifications section stored in the database are determined based on the safety specifications standards of the power industry, and the set of titles of each necessary module stored in the database is summarized based on the naming rules of the titles of each necessary module in the construction safety specifications section of a large number of tender documents.

[0050] In one specific embodiment, the necessary modules of the construction safety specification section include, but are not limited to, safety management system, safety protection measures, safe construction measures, construction site safety technical specifications, and emergency plans.

[0051] As a preferred embodiment, the specific method for determining whether each sub-item of the necessary module complies with the safety standard is as follows: obtain the safety standard of each sub-item in the necessary module, compare the safety standard of each sub-item in the necessary module with its corresponding standard, and if the safety standard of each sub-item in the necessary module is not lower than its corresponding standard, then each sub-item of the necessary module complies with the safety standard; otherwise, there are sub-items in the necessary module that do not comply with the safety standard.

[0052] As a preferred option, see [reference] Figure 3 As shown, the specific method for obtaining the safety specifications and standards of each sub-item in the necessary modules is as follows: T1: Obtain the security specifications and standards in the tender documents, and determine whether each sub-item in the necessary modules falls within the security specifications and standards in the tender documents.

[0053] If a sub-item of a necessary module falls within the safety specifications and standards outlined in the tender documents, then execute T2.

[0054] If a sub-item of a necessary module is not within the safety specifications of the tender document, then execute T3.

[0055] T2: Obtain the mandatory safety standards for the power industry for this sub-item of the necessary module and compare them with the safety standards in the tender document.

[0056] If the safety standard in the tender document is higher than or equal to the mandatory safety standard in the power industry, then the safety standard in the tender document will be used as the safety standard for that sub-item of the necessary module.

[0057] If the safety standards in the tender documents are lower than the mandatory safety standards of the power industry, then the mandatory safety standards of the power industry will be used as the safety standards for this sub-item as a necessary module.

[0058] T3: Extract the safety standards of each historical project stored in the database, and use the safety standards of the necessary module for that sub-item in historical projects of the same type as the project in the tender document as the safety standards of the necessary module for that sub-item.

[0059] T4: Obtain the safety specifications and standards for each sub-item in the necessary modules.

[0060] It should be noted that the safety standards in the bidding documents must not be lower than the mandatory safety standards of the power industry.

[0061] It should be noted that the mandatory safety standards for the power industry are formed by collecting national and local power engineering safety regulations and industry standards, and updating and maintaining them regularly.

[0062] S3. Based on the assessment results of the compliance of each tender document with security specifications, the qualified tender documents are initially selected.

[0063] It should be noted that bid documents that meet all necessary modules and sub-items in the construction safety specifications section will be screened out, while bid documents that do not meet the safety specifications will be directly eliminated.

[0064] S4. Extract the equipment and material technical parameters section from the technical content of each qualified bid document in the preliminary screening, obtain the technical parameters of the core equipment, materials and accessories, compare them with the corresponding technical parameter requirements in the bidding documents, evaluate the technical parameter compliance score of each bid document and generate a ranking.

[0065] As a preferred embodiment, the specific analysis process of step S4 includes: Obtain the title keywords for the equipment and materials technical parameters section, and extract the content of the equipment and materials technical parameters section from the technical sections of the preliminarily qualified tender documents.

[0066] Based on the equipment and material technical parameters section of each tender document, obtain the technical parameters of each core piece of equipment in each tender document and compare them with the corresponding technical parameter requirements in the tender document to analyze the compliance of each core piece of equipment in each tender document with the technical parameters.

[0067] The weights of each core device and the weights of each technical parameter in each core device are set. Based on the compliance of each technical parameter of each core device in each bid document, the compliance of the technical parameters of the core devices in each bid document is obtained through weighted fusion analysis.

[0068] It should be noted that, according to the tender document's stipulations on the tender document format, if a mandatory uniform format is required, the title words for the equipment and material technical parameters section should be extracted from the tender document's format stipulations; if a self-designed format is required, the set of title words for the equipment and material technical parameters section should be extracted from the database.

[0069] It should be noted that the method for extracting the equipment and material technical parameters section from the technical section of each qualified bid document after preliminary screening is the same as the method for extracting the technical section from the bid document itself.

[0070] As a preferred embodiment, the specific method for analyzing the conformity of the technical parameters is as follows: D1: Obtain the type of technical parameter. If it is numeric, execute D2; if it is non-numeric, execute D3.

[0071] D2: The deviation of the technical parameters is calculated by subtracting the values ​​from the technical parameter requirements in the tender document.

[0072] Obtain the linear correlation type between technical parameters and the degree of conformity of technical parameters, wherein the linear correlation type includes positive correlation and negative correlation.

[0073] Based on the quantitative mapping relationship between the set technical parameter deviation, linear correlation type and technical parameter conformity, the conformity of the technical parameters is matched to obtain the conformity of the technical parameters.

[0074] D3: Compare the technical parameters with the descriptions in the technical parameter requirements of the tender document. If the descriptions are consistent, obtain the compliance degree of the technical parameters based on the set compliance degree of the consistent descriptions.

[0075] If the descriptions are inconsistent, the technical parameter compliance rate is obtained by filtering based on the set technical parameter compliance rate corresponding to various descriptions when the descriptions are inconsistent.

[0076] It should be noted that the deviation of the technical parameters is signed and can be positive, negative or zero.

[0077] It should be noted that if the linear correlation between technical parameters and their conformity is positive, then the larger the technical parameter, the greater the conformity; if the linear correlation is negative, then the larger the technical parameter, the smaller the conformity.

[0078] As a preferred embodiment, the specific analysis process of step S4 further includes: Similarly, based on the analysis method of the compliance of the technical parameters of the core equipment in each tender document, the compliance of the technical parameters of the materials and accessories in each tender document can be obtained.

[0079] The technical parameter compliance of the core equipment, materials and accessories in each bid document is substituted into a preset compliance scoring model to obtain the technical parameter compliance score of each bid document. The model includes the correlation between the technical parameter compliance of the core equipment, materials and accessories and the technical parameter compliance score.

[0080] In this embodiment, when analyzing the compliance of technical parameters, the present invention distinguishes between numerical and non-numerical parameters and processes them differently. For numerical parameters, the deviation is calculated by subtraction and the mapping is quantified by combining linear correlation type. For non-numerical parameters, the compliance is determined by comparison of descriptions. At the same time, weights and scoring models are considered to make the evaluation of the compliance score of technical parameters more scientific.

[0081] As a preferred embodiment, the specific analysis process of step S4 further includes: sorting each bid document according to its technical parameter compliance score from high to low, generating a ranking of each bid document, and sending it to the bidding platform.

[0082] In this embodiment, the present invention elaborates on the complete operation process from extracting files and parsing content to assessing compliance with security specifications, comparing technical parameters, analyzing technical parameter compliance scores, and generating rankings, making the evaluation process operable and traceable.

[0083] In this embodiment, the present invention not only considers the compliance of equipment and material technical parameters, but also focuses on evaluating the construction safety specifications section to determine whether it contains necessary modules and whether each sub-item of the necessary modules meets safety specifications. The evaluation is carried out from both safety and quality dimensions to ensure that the selected tender documents are more reliable.

[0084] The above formulas are all dimensionless calculations. The formulas are derived from software simulations based on a large amount of collected data to obtain the most recent real-world results. The preset parameters in the formulas are set by those skilled in the art according to the actual situation.

[0085] The above embodiments can be implemented, in whole or in part, by software, hardware, firmware, or any other combination thereof. When implemented using software, the above embodiments can be implemented, in whole or in part, in the form of a computer program product.
