Description

Technical Field

[0001] The present invention relates to the field of metallurgical technology, and in particular to a method for managing the value delivery and bidding evaluation of metallurgical equipment throughout its life cycle. Background Art

[0002] At present, in addition to delivering the physical production line to the owner, the EPC general contractor in the metallurgical industry also includes digital completion delivery, and the digital content includes but is not limited to BIM three-dimensional models, equipment value, etc. The BIM model directly reflects the actual status of the project completion delivery and provides a structured basis for digital completion delivery information.

[0003] However, the value of equipment is difficult to reflect accurately and timely. It either needs to be entered manually or exported from the BIM list details and filled in offline and then imported. This is time-consuming and labor-intensive, and it is easy to make mistakes when exporting and importing the list details. Therefore, it is urgent to design a value delivery and bidding evaluation management method for metallurgical equipment throughout its life cycle to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a method for managing the value delivery and bidding evaluation of metallurgical equipment throughout its life cycle, so as to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] The value delivery system for the entire life cycle of metallurgical equipment includes a factory digital center subsystem and an EPC engineering value management subsystem. The factory digital center subsystem is used for digital delivery of completed projects. The factory digital center subsystem includes compiling a three-dimensional model, compiling a factory object TAG number, transmitting TAG number information to the EPC engineering value management subsystem, collecting value information after standardized and structured processing of each module, and displaying value information on the three-dimensional model. The EPC engineering value management subsystem includes a budget estimate module, a procurement module, a settlement module, an operation and maintenance module, and standardized and structured processing of value information. The value delivery system for the entire life cycle of metallurgical equipment also includes a bidding subsystem, which includes a bidding module, a bidding module, a bid evaluation module, and a winning bid list module.

[0007] Furthermore, the estimate module, procurement module, settlement module and operation and maintenance module in the EPC engineering value management subsystem receive the bit number information transmitted by the factory digital center subsystem, and the standardized and structured processed value information is transmitted to the factory digital center subsystem through value delivery.

[0008] Furthermore, the TAG number is the physical location code of the equipment extracted from the three-dimensional model, and the TAG number is used to encode the data transmission of the equipment list in the estimation stage, procurement stage, final settlement stage, and operation stage of the "one code for all" project.

[0009] Furthermore, the basis for project division and budget preparation is the WBS decomposition structure. The EPC engineering value management subsystem prepares or collects budget value information based on the WBS decomposition structure, transmits TAG number information to the bidding subsystem, and collects procurement, settlement and operation and maintenance value information.

[0010] Furthermore, the engineering cost database for the value delivery of the entire life cycle of metallurgical equipment is based on the WBS code and TAG code value delivery list, including the estimated value, procurement value, settlement value, and operation and maintenance value of equipment and facilities. The value can be summarized at different levels of WBS granularity.

[0011] The bidding evaluation management method for the full life cycle value delivery of metallurgical equipment includes the metallurgical equipment full life cycle value delivery system,

[0012] S1. Generate bidding list: The bidding module generates the bidding list based on the TAG number and equipment type transmitted by the procurement module of the EPC engineering value management subsystem and the BJ series template;

[0013] S2. Supplier selection: The bidding module is used to collect supplier bidding data according to the standard BJ series template. The bid evaluation module compares the sub-items and component prices of each supplier's bidding list according to the BJ series template and selects suppliers with appropriate prices;

[0014] S3. Collection of winning bid lists: The winning bid list module collects the winning bid lists according to the superior TAG code and returns them to the procurement module in the EPC engineering value management subsystem.

[0015] Furthermore, the BJ series template is a bidding template, and the value of the procurement stage is downwardly expanded and subdivided using TAG codes, further decomposing and standardizing general equipment and commonly used non-standard equipment according to components or assembly relationships to form a bidding template.

[0016] Furthermore, the BJ series templates are used for suppliers' bid quotations. The bid quotations in the BJ series templates include winning bid data, and the winning bid data are aggregated to form a procurement value. Through the association relationship of the TAG number, the procurement amount value of the previous level TAG number is assigned.

[0017] Furthermore, based on the WBS structure, TAG codes and BJ series, the digital value delivery of equipment and facilities is realized, and three standard databases are established, namely the WBS decomposition structure library, the standard equipment TAG code library, and the standard BJ series bidding template.

[0018] Furthermore, in the EPC project, the standard WBS decomposition structure library is used as the main framework of the project, and the standard TAG code library is used as the equipment list, which is mounted under the WBS structure. The standard BJ series bidding is used, and the BJ series winning equipment list is mounted under the TAG code. The procurement value is aggregated to the upper level TAG according to the winning list. That is, the TAG code is used as a bridge, which is associated with the WBS upward and the BJ series winning equipment downward.

[0019] In the above technical scheme, the present invention provides a method for managing the value delivery and bidding evaluation of the entire life cycle of metallurgical equipment. The present invention improves the digital value delivery process of the EPC general contracting project in the metallurgical industry and increases the delivery speed.

The EPC project value management subsystem prepares or collects budget value information based on the WBS decomposition structure, transmits TAG number information to the bidding subsystem, and collects procurement, settlement and operation and maintenance value information.

[0036] Furthermore, the engineering cost database for the value delivery of the entire life cycle of metallurgical equipment is based on the WBS code and TAG code value delivery list, including the estimated value, procurement value, settlement value, and operation and maintenance value of equipment and facilities. The value can be summarized at different levels of WBS granularity.

[0037] The bidding evaluation management method for the value delivery of the whole life cycle of metallurgical equipment includes the value delivery system of the whole life cycle of metallurgical equipment.

[0038] S1. Generate bidding list: The bidding module generates the bidding list based on the TAG number and equipment type transmitted by the procurement module of the EPC engineering value management subsystem and the BJ series template;

[0039] S2. Supplier selection: The bidding module is used to collect supplier bidding data according to the standard BJ series template.

[0045] Example 1

[0046] The value delivery system for the whole life cycle of metallurgical equipment includes the factory digital center subsystem and the EPC engineering value management subsystem. The factory digital center subsystem is used for digital delivery of completed equipment. The factory digital center subsystem includes compiling three-dimensional models, compiling factory object TAG numbers, transmitting TAG number information to the EPC engineering value management subsystem, collecting value information after standardized and structured processing of each module, and displaying value information on the three-dimensional model. The EPC engineering value management subsystem includes the budget module, procurement module, settlement module, operation and maintenance module, and standardized and structured processing of value information. Based on the content of digital delivery and the management requirements of the EPC project itself, the equipment value life cycle has four main stages, namely, the budget stage, procurement stage, settlement stage, and operation and maintenance stage. Among them, the procurement stage has the longest cycle, the large amount of data, and involves bidding, bid evaluation and other processes. The four stages of metallurgical equipment are combined with three-dimensional models to realize the value delivery of the whole life cycle, optimize the bidding process of the equipment procurement stage, and the value delivery system for the whole life cycle of metallurgical equipment also includes the bidding subsystem, which includes the bidding module, the bidding module, the bid evaluation module and the winning bid list module.

[0047] The estimate module, procurement module, settlement module and operation and maintenance module in the EPC engineering value management subsystem receive the bit number information transmitted by the factory digital center subsystem, standardize and structure the value information, and deliver the standardized and structured value information to the factory digital center subsystem through value delivery; the TAG bit number is the physical location code of the equipment extracted from the three-dimensional model, and the TAG bit number uses this code to transmit data in the estimate stage, procurement stage, settlement stage, and operation stage of the equipment list in the "one code for all" project. After the equipment list is one code for all, the amount of value generated in each stage has a direct correlation (horizontally), and the WBS design realizes hierarchical decomposition (superior and subordinate relationship), and uses WBS coding combined with TAG bits to establish an association relationship. Through the WBS structure and TAG code, digital value delivery of various granularities in the stages of equipment and facility estimate, procurement, settlement value, etc.

[0048] WBS coding rules: WBS coding rules can reflect the hierarchical characteristics, and there are two coding methods.

[0049] Coding method 1: Divide the levels by digits. The example is as follows: the first two digits XX represent the first level, the third and fourth digits represent the second level, and the last digit represents the third level. The WBS decomposition structure of standard process facilities is established. Coding method 1 example:

[0050]

[0051] Coding method 2: Use separator codes to represent levels, with one separator representing level 1. An example is as follows: A standard process facility WBS decomposition structure is established based on levels such as level 1 (process), level 2 (facility), level 3 (system), and level 4 (area).

[0052] Encoding method 2 example:

[0053]

[0054] The implementation methods of encoding method one or two are all within the scope of the present invention. TAG code encoding rules: TAG equipment bit number is set to 8 segments, among which: the base code is 2 Arabic numerals, the facility code is 2 uppercase letters, the facility serial number is 1 Arabic numeral or uppercase letter (1-9, ABC... in sequence after greater than 10), the WBS code is 3 Arabic numerals, the WBS extension code is 3 Arabic numerals, the separator is 1 half-width symbol "-", the professional code is 1 Arabic numeral or uppercase letter (1-9, ABC... in sequence after greater than 10), and the serial number is 3 Arabic numerals. Examples are as follows:

[0055]

[0056] Note: "N" represents Arabic numerals, "A" represents uppercase English letters, and "X" indicates that the number position can be either Arabic numerals or uppercase English letters.

[0057] The basis for the division of engineering projects and the preparation of budget estimates is the WBS decomposition structure. In the EPC engineering value management subsystem, budget estimate value information is compiled or collected based on the WBS decomposition structure, and TAG number information is transmitted to the bidding subsystem to collect procurement, settlement and operation and maintenance value information; the engineering cost library for the value delivery of the entire life cycle of metallurgical equipment is based on the WBS code and TAG code value delivery list, including the budget estimate value, procurement value, settlement value, and operation and maintenance value of equipment and facilities. The value can be summarized at different levels of WBS granularity.

[0058] Example 2

[0059] This embodiment is further limited on the basis of the first embodiment. The bidding evaluation management method for the full life cycle value delivery of metallurgical equipment includes a metallurgical equipment full life cycle value delivery system.

[0060] S1. Generate bidding list: The bidding module generates the bidding list based on the TAG number and equipment type transmitted by the procurement module of the EPC engineering value management subsystem and the BJ series template;

[0061] S2. Supplier selection: The bidding module is used to collect supplier bidding data according to the standard BJ series template. The bid evaluation module compares the sub-items and component prices of each supplier's bidding list according to the BJ series template and selects suppliers with appropriate prices;

[0062] S3. Collection of winning bid lists: The winning bid list module collects the winning bid lists according to the superior TAG code and returns them to the procurement module in the EPC engineering value management subsystem.

[0063] The BJ series templates are bidding templates, and the value of the procurement stage is expanded and subdivided downward using TAG codes, further decomposing and standardizing general equipment and commonly used non-standard equipment according to components or assembly relationships to form a bidding template; the BJ series templates are used for suppliers' bid quotations. The bid quotations in the BJ series templates include winning bid data, and the winning bid data are aggregated to form the procurement value. Through the association relationship of the TAG number, the procurement amount value of the upper-level TAG number is assigned.

[0064] Classification of BJ series bidding templates and component decomposition method: According to the similarity of equipment procurement components, a unified template is formulated, the data format is standardized, and a standard is formed. The equipment procurement quotation data is stored in a structured manner (previously it was an attachment), so that the bidding data can be refined and compared between different bidders. According to the equipment procurement category, several types of equipment procurement inquiry and quotation forms are set, including: BJ1 electromechanical product inquiry and quotation form, BJ2 three-electric, public auxiliary non-standard or large equipment inquiry and quotation form, BJ3 electrical panels, boxes, cabinets inquiry and quotation form, BJ4 equipment design inquiry and quotation form, BJ5 non-standard mechanical equipment inquiry and quotation form, BJ6 single-machine complete equipment inquiry and quotation form, BJ7 cooperative manufacturing equipment quotation form, BJ8 reused equipment inquiry and quotation form, BJ9 complete equipment inquiry and quotation form and BJ10 imported equipment (bid) quotation form.

[0065] For each type of equipment purchase inquiry and quotation, first set up the equipment purchase sub-item and set a unique sub-item standard code. For example, the "single machine complete set equipment inquiry and quotation" is divided into 16 sub-items, namely host structure equipment, host mechanical supporting equipment, etc., and each sub-item is set with a standard sub-item code: BJ6-01, BJ6-02, etc.

[0066] For each type of equipment procurement sub-item, set equipment procurement parts and set unique standard part codes. For example, "Host structure equipment" sets four types of procurement parts, namely general structural parts, processed structural parts, metal processing parts, and special materials. Each procurement part has a standard part code: BJ6-01-01, BJ6-01-02, BJ6-01-03, BJ6-01-04.

[0067] Based on the WBS structure, TAG code and BJ series, the digital value delivery of equipment and facilities is realized. Three standard databases are established, namely the WBS breakdown structure library, the standard equipment TAG code library and the standard BJ series bidding template. In the EPC project, the standard WBS breakdown structure library is cited as the main framework structure of the project, and the standard TAG code library is cited as the equipment list, which is mounted under the WBS structure. The standard BJ series is used for bidding, and the list of BJ series winning equipment is mounted under the TAG code. The procurement value is aggregated to the upper level TAG according to the winning list. That is, the TAG code is used as a bridge, which is associated with the WBS upward and with the BJ series winning equipment downward.

[0068] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
