Description

Technical Field

[0001] The invention belongs to the technical field of bidding data management and relates to a comprehensive management system for bidding data of engineering construction projects. Background Art

[0002] Engineering construction project bidding data refers to a series of information generated during the bidding process of engineering construction projects, including basic project information, bidding unit information, bidding document information, tender document information, bid evaluation information and winning bid information. These data are of great significance to ensuring the fairness, justice and openness of the bidding process and the smooth implementation of the project. Therefore, they need to be managed comprehensively.

[0003] For example, the Chinese patent with the authorization publication number CN116433179A discloses a method for standardizing public bidding information based on a database. The present invention discloses a method for standardizing public bidding information based on a database, including the following steps: S1: confirm the nature of the bidding project. S2: prequalification. S3: scheme design. S4: review of bidding documents. S5: start bidding. S6: confirm the result and notify the result. S7: competitive negotiation. S8: material procurement. By confirming the nature of the bidding project, it is possible to confirm whether the nature of the bidding document is an engineering construction project, government procurement or state-owned enterprise procurement, which is convenient for subsequent targeted bidding. Prequalification can be used to preliminarily screen bidders to improve efficiency. Through scheme design, the technical, economic and management characteristics of the bidding project, as well as the function, scale, quality, price, progress, service and other demand targets of the bidding project can be analyzed and mastered. By confirming the result and notifying the result, the bidding unit can confirm and notify the winning bidder within the specified time and place.

[0004] The above existing technologies have the following deficiencies: 1. Currently, the bidding qualification analysis of engineering construction projects is only conducted based on the credit of the bidding unit, and the bidding qualification analysis is not conducted in multiple dimensions in combination with the qualification information, performance information and credit score of the bidding unit. The comprehensiveness of the bidding qualification analysis results cannot be guaranteed, which increases the risk of subsequent project implementation process, thereby increasing the difficulty and cost of subsequent project management, and at the same time affecting the subsequent smooth progress and overall benefits of the project.

[0005] 2. Currently, when conducting bid compliance analysis of bidding units, the focus is mainly on the bid compliance analysis of the bidding units, and insufficient attention is paid to the compliance analysis of the bidding units' planned schedule, which in turn increases the risk of project delays and makes it impossible to accurately evaluate the rationality of the bidding units' resource allocation. Summary of the invention

[0006] In view of this, in order to solve the problems raised in the above background technology, a comprehensive management system for bidding data of engineering construction projects is now proposed.

[0028] Furthermore, the bidding qualification judgment of the bidding units includes: extracting the bidding qualification index η of each bidding unit in the target engineering construction project j .

[0029] If the bidding qualification index of a bidding unit is lower than the set reference bidding qualification index, the qualified index will be regarded as the bidding qualification judgment result of the bidding unit.

[0030] If the bidding qualification index of a bidding unit is greater than or equal to the set reference bidding qualification index, then unqualified will be used as the bidding qualification judgment result of the bidding unit, and then the bidding qualification judgment results of each bidding unit in the target engineering construction project will be obtained.

[0039] The bid quotation component categories of each qualified bidding unit are matched with the budget quotation component categories of the target engineering construction project to obtain the number of matched budget quotation component categories of each qualified bidding unit. The ratio of the number of matched budget quotation component categories to the bid quotation component categories is taken as the ratio of the number of matched budget quotation component categories of each bidding unit, denoted as ψ p .

[0040] Statistics on the technical compliance of each qualified bidding unit p , ψ′ and τ′ are the ratio of the number of budget quotation categories and the bid quotation deviation rate of the reference respectively, and e is a natural constant.

[0059] It should be added that the bidding information materials of the target engineering construction project include: the bidding information keywords of the target engineering construction project, budget quotations, budget quotation composition categories and target plan progress information; the bidding information materials of the target engineering construction project include: the qualification information, performance information, credit score of each bidding unit in the target engineering construction project, as well as the quotation information and plan progress information of each qualified bidding unit.

[0060] The bidding information classification module is used to classify the bidding information materials according to the bidding information materials of the target engineering construction project to obtain the bidding information of the target engineering construction project.

[0061] Exemplarily, the classification of bidding information materials includes: extracting various bidding information keywords of the target engineering construction project from the bidding information materials of the target engineering construction project, and combining the various bidding information keywords of the target engineering construction project into a bidding information keyword set of the target engineering construction project, denoted as ε.

[0062] Extract the storage bidding information keywords of each storage engineering construction project from the engineering construction project management cloud platform, and then form a storage bidding information keyword set of each storage engineering construction project, denoted as δ i , i is the serial number of the storage engineering construction project, i=1,2,......,m.

[0063] Count the text similarities of each storage engineering construction project The maximum value is selected from the text similarities as a similar storage engineering construction project of the target engineering construction project.

[0064] The bidding information classification method of similarly stored engineering construction projects is extracted from the engineering construction project management cloud platform, and then the bidding information of the target engineering project is classified in the same way as the bidding information classification method of similarly stored engineering construction projects to obtain the classified bidding information, which is used as the bidding information of the target engineering construction project.

[0065] The bidding information analysis module is used to perform bidding qualification index analysis based on the bidding information and bidding information data of the target engineering construction project, and obtain the bidding qualification index of each bidding unit in the target engineering construction project.

[0066] The embodiment of the present invention determines the bidding qualifications of bidding units through the bidding qualification index of each bidding unit, thereby screening out qualified bidding units, thereby reducing the in-depth review of unqualified units, improving the bidding efficiency, and avoiding the waste of time and resources due to qualification issues in the subsequent review process.

[0067] See also Figure 2 As shown, illustratively, the bidding qualification index analysis includes: A1, extracting the qualification information of each bidding unit in the target engineering construction project from the bidding information of the target engineering construction project, and then calculating the qualification index φ of each bidding unit in the target engineering construction project j , j is the serial number of the bidding unit, j=1,2,......,n.

[0068] Furthermore, the statistical qualification index of each bidding unit in the target engineering construction project includes: A1-1, extracting the qualification requirement information of the bidding unit from the bidding information of the target engineering construction project, and then extracting the target qualification level from the qualification requirement information.

[0069] A1-2. Extract the qualification level of each bidding unit from the qualification information of each bidding unit in the target engineering construction project. If the qualification level of a bidding unit is greater than or equal to the target qualification level, the qualification index of the bidding unit is recorded as 1. Otherwise, the qualification index of the bidding unit is recorded as 0. In this way, the qualification index of each bidding unit is obtained, which is recorded as φ j ,φ j The value is 0 or 1.

[0070] A2. Extract the performance information of each bidding unit in the target engineering construction project from the bidding information of the target engineering construction project, and then calculate the performance qualification index of each bidding unit in the target engineering construction project

[0071] Furthermore, the statistical performance qualification index of each bidding unit in the target engineering construction project includes: A2-1, extracting the performance quantity, scale and quality rating of each bidding unit from the performance information of each bidding unit in the target engineering construction project, and recording the performance quantity of each bidding unit as D j .

[0072] A2-2. Match the performance scale of each bidding unit with the target performance scale to obtain the matching performance scale number D of each bidding unit. j ′.

[0073] A2-3. Import the performance quality rating of each tendering unit into the performance quality qualified index analysis model to obtain the performance quality qualified index of each tendering unit, which is recorded as α j .

[0074] It should be added that the specific analysis process of the performance quality qualified index analysis model is as follows: the project acceptance rating and project quality evaluation rating are extracted from the performance quality ratings of each bidding unit. If the project acceptance rating in the performance quality rating of a bidding unit is excellent, it means that the project quality is excellent in all aspects, then the project acceptance score is recorded as μ 1 .

[0075] In a specific real-time example, the project acceptance score for a project with an excellent acceptance rating is 80-90 points. For the convenience of analysis, the specific value can be 85 points.

[0076] If the project acceptance rating of a bidding unit is qualified in the performance quality rating, the project acceptance score is recorded as μ 2 .

[0077] If the project acceptance rating of a bidding unit is unqualified in the performance quality rating, the project acceptance score is recorded as 0, and the project acceptance score z is obtained. 1 , z 1 The value is μ 1 or μ 2 or 0.

[0078] Statistical project acceptance rating qualification indexω 1 , z′ is the total score of project acceptance.

[0079] If a project evaluation rating in a certain performance quality rating of a bidding unit is excellent, that is, the project of the bidding unit has no quality problems and complaints during the implementation and after delivery, indicating that its quality control is good, then the project evaluation score is recorded as μ 3 .

[0080] If a project is rated as good in a certain performance quality rating of a bidding unit, that is, there are a few quality problems and complaints, but the bidding unit can solve them in time and does not affect the normal use of the project and the satisfaction of the owner, then the project evaluation score is recorded as μ 4 .

[0081] If a project is rated as average in a certain performance quality rating of a bidding unit, that is, the project has many quality problems and complaints, or the problems are not solved in time, which has a great impact on the normal use of the project and the satisfaction of the owner, then the project evaluation score will be recorded as μ 5 , and then get the project evaluation score z 2 , z 2 The value is μ 3 or μ 4 or μ 5 , according to ω 1 The statistical method is similar to the statistical method to obtain the project evaluation and rating qualification index, denoted as ω 2 .

[0082] Calculate the qualified index σ of the performance quality rating of the bidding unit, σ=z 1 *f 1 +z 2 *f 2 , f 1 and f 2 are the weights of the project acceptance rating qualification index and project evaluation rating qualification index, respectively. 1 +f 2 =1,f 1 >f 2 .

[0083] It should be added that project acceptance ratings are usually based on clear technical standards, specifications and contract requirements, and are highly objective. For example, the acceptance of construction projects will be strictly checked based on specific indicators such as structural safety, construction quality, and functional compliance. Only when these standards are met can the project pass the acceptance. This ensures that the project has reached a basic level of qualification in terms of technology and quality, and is a hard measure of project results. Project evaluation ratings may be affected by subjective factors, and their objectivity is relatively weak. Therefore, setting f 1 >f 2 For the convenience of analysis, f 1 The specific value can be 0.6, f 2 The specific value can be 0.4.

[0084] According to the statistical method of σ, the qualified index of each performance quality rating of the tendering unit is obtained in the same way, and the mean is calculated. The calculation result is used as the qualified index of the performance quality of the tendering unit. Then, according to the statistical method of the qualified index of the performance quality of the tendering unit, the qualified index of the performance quality of each tendering unit is obtained in the same way, which is recorded as α j .

[0085] A2-4. Statistical performance index θ of each bidding unit in the target engineering construction project j , D″, K and α′ are the reference performance quantity, matching performance scale ratio and performance quality qualification index respectively.

[0086] It should be added that D″, K and α′ are all extracted from the comprehensive management technical specification table of the engineering construction project bidding data.

[0087] A3. Extract the reputation scores of each bidding unit in the target engineering construction project from the bidding information of the target engineering construction project, and then use the ratio of the reputation score of each bidding unit to the total reputation score as the reputation qualification index of each bidding unit in the target engineering construction project, denoted as γ j .

[0088] A4. Statistical target project construction project bidding qualification index η of each bidding unit j , b 1 、b 2 and b 3 are the weights of the qualification index, performance index and reputation index, respectively. 1 +b 2 +b 3 =1, b 1 >b 2 >b 3 .

[0089] It should be added that qualification is an important proof that a bidding unit can legally participate in engineering construction projects and has the corresponding professional capabilities. Performance is the record of a bidding unit's actual participation in similar projects in the past. It can directly reflect the actual construction capabilities, management level and project results of an enterprise in a specific field. However, qualification is a prerequisite for an enterprise to legally participate in engineering construction. Therefore, the weight of the qualification index is greater than the weight of the performance index. Reputation mainly reflects the integrity and reputation of the bidding unit in commercial activities, but it does not directly affect the implementation capability and quality of the project like qualification and performance. Therefore, b is set. 1 >b 2 >b 3 , for the convenience of analysis, b 1 The specific value can be 0.45, b 2The specific value can be 0.35, b 3 The specific value can be 0.2.

[0090] When performing bid qualification index analysis, the embodiment of the present invention improves the rationality of resource allocation by setting weights for the qualification qualification index, the performance qualification index, and the reputation qualification index, thereby increasing the attention paid to key factors and improving the clarity of the bid qualification index calculation results, providing an intuitive basis for judgment for the bidding unit, thereby improving decision-making efficiency.

[0091] The embodiment of the present invention analyzes the bidding qualification index of each bidding unit in the target engineering construction project through the qualification index, performance index and reputation index of each bidding unit in the target engineering construction project, breaking the current deficiency of not combining the qualification information, performance information and reputation score of the bidding unit for multi-dimensional bidding qualification analysis, ensuring the comprehensiveness of the bidding qualification analysis results, thereby reducing the risk of subsequent project implementation process, thereby increasing the difficulty and cost of subsequent project management, and ensuring the smooth progress and overall benefits of the subsequent project.

[0092] The bidding qualification judgment module is used to judge the bidding qualifications of the bidding units according to the bidding qualification index of each bidding unit in the target engineering construction project, and obtain the bidding qualification judgment results of each bidding unit in the target engineering construction project.

[0093] Exemplarily, the bidding qualification judgment of the bidding units includes: extracting the bidding qualification index η of each bidding unit in the target engineering construction project j .

[0094] If the bidding qualification index of a bidding unit is lower than the set reference bidding qualification index, the qualified index will be regarded as the bidding qualification judgment result of the bidding unit.

[0095] If the bidding qualification index of a bidding unit is greater than or equal to the set reference bidding qualification index, then unqualified will be used as the bidding qualification judgment result of the bidding unit, and then the bidding qualification judgment results of each bidding unit in the target engineering construction project will be obtained.

[0096] The bidding conformity confirmation module is used to record each bidding unit that is qualified in the bidding qualification judgment result as each qualified bidding unit, and then confirm the bidding information of the target engineering construction project based on the bidding information data of each qualified bidding unit.

[0097] See also Figure 3 As shown, illustratively, the confirming of the bidding information of the target engineering construction project includes: B1, extracting the quotation information and planned progress information of each qualified bidding unit from the bidding information materials of each qualified bidding unit.

[0098] B2. According to the quotation information of each qualified bidding unit, the quotation compliance of each qualified bidding unit is calculated. p , p is the serial number of qualified bidding units, p = 1, 2,......, q.

[0099] Furthermore, the statistics of the bid compliance of each qualified bidding unit include: B2-1, extracting the bid price and bid price component categories from the bid information of each qualified bidding unit, and recording the bid price of each qualified bidding unit as ξ p .

[0100] B2-2. Extract the budget quotation and budget quotation component categories from the bidding information of the target engineering construction project, and record the budget quotation of the target engineering construction project as ξ′.

[0101] B2-3. Calculate the bid price deviation rate τ of each qualified bidding unit p ,

[0102] B2-4. Match the bid quotation component categories of each qualified bidding unit with the budget quotation component categories of the target engineering construction project to obtain the number of matched budget quotation component categories of each qualified bidding unit. The ratio of the number of matched budget quotation component categories to the bid quotation component categories is taken as the ratio of the number of matched budget quotation component categories of each bidding unit, denoted as ψ p .

[0103] B2-5. Count the technical proposal compliance of each qualified bidding unit. p , ψ′ and τ′ are the ratio of the number of budget quotation categories and the bid quotation deviation rate of the reference respectively, and e is a natural constant.

[0104] It should be added that ψ′ and τ′ are both extracted from the comprehensive management technical specification table of the engineering construction project bidding data.

[0105] B3. According to the plan progress information of each qualified bidding unit, calculate the plan progress compliance degree l′ of each qualified bidding unit p .

[0106] Furthermore, the statistical calculation of the plan progress compliance of each qualified bidding unit includes: B3-1, extracting the target plan progress information from the bidding information of the target engineering construction project, and then extracting the total target duration and the target duration of each plan stage, and recording the total target duration as t 0 .

[0107] B3-2. Extract the total planned duration of each qualified bidding unit and the planned duration of each planning stage from the planned progress information of each qualified bidding unit, and record the total planned duration of each qualified bidding unit as t p .

[0108] B3-3. Match and compare the target duration of each planning stage with the planned duration. If the planned duration of a planning stage is less than or equal to the target duration of the planning stage, the planning stage is recorded as a conforming planning stage. Then, the number of conforming planning stages of each qualified bidding unit is obtained, and the ratio of the number of conforming planning stages to the number of planning stages is taken as the conforming planning stage number ratio, which is recorded as

[0109] B3-4. Calculate the planned progress compliance of each qualified bidding unit l′ p , The ratio of the number of planned stages that meet the reference is set.

[0110] It should be added that It is extracted from the comprehensive management technical specification table of engineering construction project bidding data.

[0111] B4. Compliance of bidding information of qualified bidding units in the target engineering construction project β p , β p =min(l p *r 1 +l′ p *r 2 ), r 1 and r 2 are the weights of the quotation compliance and the planned progress compliance, r 1 +r 2 =1, r 1 >r 2 .

[0112] It should be added that the reason why the weight of quotation compliance is relatively large is that for the tendering unit, project cost control is crucial, and quotation compliance is directly related to the budget execution and capital investment of the project. The reason why the weight of planned schedule compliance is relatively small is that although the planned schedule is also important for the smooth implementation of the project, in actual operation, the schedule plan can often be adjusted according to the actual situation of the project, so setting r 1 >r 2 , for the convenience of analysis, r 1 The specific value can be 0.6, r 2 The specific value can be 0.4.

[0113] B5. The compliance degree and bidding information of each qualified bidding unit in the target engineering construction project shall be used as the bidding information of the target engineering construction project.
