Description

Technical Field

[0001] The present invention relates to the technical field of computer automatic management, and in particular to a project bidding management method and system. Background Art

[0002] The bidding work of engineering projects is generally managed by a special procurement department. In the bidding process, the bidding personnel of Party A need to send project information and requirements to each Party B unit by email. The bidders in Party B prepare bids and then send them to Party A. Party A organizes judges to score the company's qualifications, historical performance, project planning, quotations, etc. according to different proportions, and finally selects the winning bidder. In this model, it is easy to leak the materials submitted by the tenderer, and the bidding process is not transparent enough, and there is suspicion of internal determination. The winning bid is not the best bid and is inefficient. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a project bidding management method and system, which can automatically manage according to the existing project bidding model, improve efficiency while ensuring the fairness and transparency of bidding.

[0004] A project bidding management method of the present invention comprises the following steps:

[0005] (1) When preparing the bid, the bidder shall scan the bid documents into electronic scans, which shall be packaged and classified according to the fixed information files and project-related information files for delivery, and the fixed information files and project-related information files of the same bidder shall be linked;

[0006] (2) Fixed information files are sent directly to the tenderer's bid evaluation document library, and project-related information files are first sent to the information extraction module to extract relevant information, including project technical information and quotation information. The relevant information is extracted into the standard template to generate the bid evaluation file;

[0007] (3) Send the bid evaluation documents to the bid evaluation document library, classify and store them with fixed information documents, and output them randomly in random order for bid evaluation;

[0008] (4) After the bid evaluation is completed, the project-related information files corresponding to the bid evaluation documents are matched with the fixed information files using the associated information, and the scores are calculated to complete the bid evaluation.

[0009] Furthermore, the information for associating the fixed information file and the project-related information file in step (1) is an official seal image, and the steps for extracting the official seal image are as follows:

[0010] (1-1) Perform color recognition on the electronic copies of the fixed information files and project-related information files of the same bidder, scan the pixels in the electronic copies line by line, and mark the pixel a when the RGB value of the pixel a is within the range of (255 ≥ R > 200, 50 ≥ G > 0, 50 ≥ B > 0);

[0011] (1-2) extracting the boundary of the marked pixel area, and determining it as an official seal image when the boundary is circular and contains recognizable text information;

[0012] (1-3) The text within the boundary is recognized. If the text in the official seal images in the electronic copies of the fixed information file and the project-related information file is consistent, the two files are associated, and the official seal images of the two files are extracted and stored as associated information.

[0013] Furthermore, the bidder needs to prepare project-related information documents in a specific format, including: adding specific symbols at the beginning and end of the text of the project technical information; using tables to prepare quotation information; the steps for extracting project technical information and quotation information include:

[0014] (2-1) Convert the RGB image of the electronic version of the project-related information file into a grayscale image using the conversion formula R*0.3+G*0.59+B*0.11;

[0015] (2-2) Scan the project-related information files line by line, and reassign pixels with grayscale values ​​between 60 and 111.5 to a range of 200 to 255;

[0016] (2-3) Recognize specific symbols in project-related information files, directly intercept the content between two specific symbols, and extract it into the technical information part of the standard template;

[0017] (2-4) Perform box recognition on the project-related information file, directly capture the content in the box, and extract it into the quotation information part of the standard template.

[0018] Furthermore, access to the information extraction module requires the highest access permission.

[0019] The present invention also provides a project bidding management system, comprising a first upload port, a second upload port, a bid evaluation document library and an information extraction module;

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] like Figure 1-Figure 4 As shown: a project bidding management system of this embodiment includes a first upload port, a second upload port, a bid evaluation document library and an information extraction module;

[0032] The bid evaluation document database is divided into a fixed information database and a related information database;

[0033] The first upload port is connected to a fixed information base in the bid evaluation document library, the second upload port is connected to an input end of an information extraction module, and the output end of the information extraction module is connected to a related information base of the bid evaluation document library;

[0034] The files in the fixed information database are sorted according to the upload time, and the files in the related information database are sorted randomly.

[0035] The bidding process includes:

[0036] Step 1: The bidder prepares the bid document according to the requirements of the tenderer; the general bid document consists of three parts, namely the credit part, the business part and the technical part;

[0037] The credit section includes a series of contents such as company qualifications and company situation introduction, as well as other relevant contents such as other documents required by the bidding documents, including the company's performance and various certificates and reports.

[0038] The technical part includes technical solutions such as project description, design and construction plan, bill of quantities, staffing, drawings, tables and other technology-related materials.

[0039] The commercial part includes the bidding quotation description, the total bidding price, the main material price list and the contract conditions (general and special), etc.

[0040] The credit part is related to the information of the bidding company itself and generally rarely changes, so it is defined as a fixed information file in this embodiment.

[0041] The technical part and the commercial part need to be formulated according to the specific bidding project of the bidding party and need to be changed according to different projects. Therefore, they are defined as: project-related information files in this embodiment.

[0042] When preparing the bid documents, the bidder shall scan the bid documents into electronic scans, which shall be packaged and classified according to the fixed information files and project-related information files for delivery;

[0043] The electronic copy of the fixed information file is directly uploaded to the fixed information library in the bid evaluation file library through the first upload port and sorted by upload time;

[0044] The electronic files of project-related information are uploaded to the information extraction module through the second upload port, sorted by upload time, and queued for information extraction;

[0045] The information extraction module associates the fixed information file and the project related information file of the same bidder, and the information associated with the fixed information file and the project related information file is the official seal that can represent the identity information of the bidder;

[0046] Since all electronic documents are scanned images, it is necessary to extract the official seal image of the bidder from the electronic document. The specific steps of extraction include:

[0047] (a) Perform color recognition on the electronic copies of the fixed information files and project-related information files of the same bidder, mainly focusing on the red color used in the official seal. The host of the information extraction module is used to scan the pixels in the electronic copies line by line. When the RGB value of pixel a is within the range of (255≥R>200, 50≥G>0, 50≥B>0), the pixel visually appears to be red close to the official seal, so pixel a is marked until all pixels are scanned;

[0048] (b) extracting the boundary of the marked pixel area. There are many algorithms for boundary extraction, such as calculating the gradient value of the pixel, finding out the pixel point with a gradient value greater than a threshold as the boundary, etc. Since it is a prior art, it will not be described in detail.

[0049] When the boundary is a circle and there is recognizable text information inside, when recognizing the circle, the pixels at the boundary are substituted into the formula (xa) 2 +(yb) 2 =r 2 The judgment can be made in , where (x, y) is the pixel coordinates at the boundary, and (a, b) is the coordinates of the center of the circle. The cross intersection method can be used to determine the circle, that is, extract a group of pixel points with equal or similar horizontal coordinates but large vertical coordinate difference to construct a vertical straight line, and another group of pixel points with equal or similar vertical coordinates but large horizontal coordinate difference to construct a horizontal straight line. The intersection point of the vertical straight line and the horizontal straight line can be defined as the origin;

[0050] When at least 80% of the pixels roughly meet the above formula, it can be determined as an official seal image;

[0051] (c) Identify the text within the boundary. If the text in the official seal images in the electronic copies of the fixed information file and the project-related information file is consistent, the two files are associated, and the official seal images of the two files are extracted and stored as associated information.

[0052] Step 2: It is necessary to remove the information that can reflect the identity of the bidder contained in the project-related information documents. Since the text information of the bidding documents is too complex and the format is not uniform, it is necessary to set a special format for the bidding documents prepared by the bidder; including:

[0053] ①Add specific symbols at the beginning and end of the text of the project technical information; ②Use tables to create quotation information;

[0054] The above-mentioned format can be used to quickly extract information. The steps for extracting project technical information and quotation information include:

[0055] (a) Convert the RGB image of the electronic version of the project-related information file into a grayscale image using the conversion formula R*0.3+G*0.59+B*0.11. Convert the scanned electronic version in color format into a grayscale image containing only grayscale information, which can reduce the complexity of processing;

[0056] (b) Scan the project-related information files line by line and re-assign the pixels with grayscale values ​​between 60-111.5, with the range of 200-255. After the grayscale conversion of the red official seal image, the grayscale value of the pixels is between 60-111.5. By re-assigning the grayscale value of the official seal image, the official seal image can be replaced with the white part close to the background, thereby erasing the information that can reflect the identity of the bidder;

[0057] (c) Identify specific symbols in project-related information files, directly intercept the content between two specific symbols, and extract it into the technical information part of the standard template;

[0058] Since the words "Technical confidence" reflect the technical strength of the bidder, if the existing text recognition technology is used, it may cause recognition errors, making it difficult to understand the bidder's technical solution or even misunderstand it. Therefore, this part can be directly intercepted and placed in the standard template and provided to the judges;

[0059] (d) Perform box recognition on the project-related information files, directly capture the content in the box, and extract it into the quotation information part of the standard template. The quotation part is more important, so after directly recognizing the box, directly capture the image inside and provide it to the judges.

[0060] Therefore, in this step, the fixed information file is generally sent directly to the bid evaluation file library of the tenderer, and the project related information file is first sent to the information extraction module to extract relevant information, including project technical information and quotation information, and the relevant information is extracted into the standard template to generate the bid evaluation file;

[0061] Step 3: Send the bid evaluation documents to the relevant information database of the bid evaluation document library, so as to classify and store them with the fixed information documents, and output them randomly in disorder for bid evaluation;

[0062] Step 4: The judges score and evaluate the bids according to the fixed information and unknown information of the bidders. After the evaluation is completed, the project-related information files corresponding to the evaluation documents are matched with the fixed information files using the associated information. The corresponding scores can be summed up to obtain the final scores of each bidder, and the evaluation is completed by scoring.

[0063] Specifically, when associating, the associated information (ie, the official seal image) is compared one by one with the associated information in the disordered project-related information file in the order of the fixed information file, and the association is completed if the internal texts match.

[0064] In addition, the information extraction module is an encrypted server, and access to the encrypted server requires the highest access rights to prevent the internally stored project-related information files from being tampered with.

[0065] In summary, a project bidding management method and system of the present invention divides the bidding documents provided by the bidder into fixed information files related to the business information of the unit and project related information files specially prepared for the project. The fixed information files are directly submitted to the bid evaluation party for evaluation and scoring; the project related information files are processed by image processing to extract the project technical information and quotation information contained therein into a standard template, thereby eliminating the information related to the bidder's identity in the project related information files, and submitting them to the bid evaluation party for evaluation and scoring after random order; after the scoring is completed, the project related information files and fixed information files of the same bidder are associated through the associated information to obtain the final score; thereby, the bidding process is made fairer by excluding the identity information of the bidder, and the bidding documents are automatically sorted by the system to eliminate some irrelevant information, thereby making the bidding process more efficient.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
