[0051] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1 The first aspect of the present invention provides a BIM-based engineering project procurement management system, including: a procurement management module, and a list generation module and a terminal processing module connected thereto;

[0053] List generation module: obtain the design drawings and parameters of the project, build the BIM model based on the design drawings and parameters; extract component information from the BIM model, and generate a purchase list based on the component information; the component information includes component name, quantity, specification and material

[0054] Procurement management module: screen several suppliers according to the procurement list, obtain supply information of several suppliers, calculate the evaluation coefficients of several suppliers; screen out the final supplier from the suppliers based on the evaluation coefficient; and,

[0055] Obtain product information of several components, divide the project into several project cycles, and match product information with several project cycles; obtain delivery information of final supplier products; monitor the progress of the project in real time to determine whether a new round of procurement is needed; if yes, generate a procurement processing signal; if no, continue to detect the progress of the project;

[0056] Terminal processing module: processes products based on procurement processing signals.

[0057] See also Figure 2 , obtain the design drawings and parameters of the engineering project, where the design drawings include plan views, elevation views, and section views; the parameters include the size, material, and position of the components; select BIM modeling software, draw floor lines and grid lines according to the design drawings, draw several components in the BIM modeling software in turn, set the parameters of the components according to the parameters, and obtain the BIM model.

[0058] For example: Assuming that there is a design drawing and parameters of an engineering project, select BIM software Revit / ArchiCAD to draw the project, set the parameters of the components according to the parameters, and finally get the BIM model.

[0059] Extract component information from the BIM model, and determine whether the component information contains all types of information. If yes, retain the corresponding component information; if not, supplement the corresponding missing information; number the component information i according to the component name; arrange the corresponding data types according to the component number to obtain a purchase list; where i = 1, 2, ..., n, and n is a positive integer.

[0060] For example, suppose three sets of component information are extracted from the BIM model, and the integrity of the component information is judged. It is found that the second set of data is missing the material of the component; then the component material of the second set of data is supplemented;

[0061] According to the collected results, the component information is sorted and numbered as 1, 2, and 3.

[0062] Filter several suppliers according to the purchase list, obtain the supply information of several suppliers, divide several suppliers according to the purchase list, and obtain the supplier number ij; mark the reputation score, product score and the number of product types as XFij, CFij and CSij respectively; where j represents the supplier number, j=1,2,…,m, m is a positive integer; calculate the supplier evaluation coefficient through the formula PXij=α×ln(CSij+1)+β×XFij+γ×CFij; where α, β and γ are proportional coefficients greater than 0.

[0063] For example: suppose that the suppliers of component 2 are screened and three suppliers are selected; α=10,β=0.5,γ=0.5; the supply information of the three suppliers is obtained as follows:

[0064] First supplier: reputation score XF21 = 94; product score CF21 = 89; number of product types CS21 = 5; then the evaluation coefficient PX21 = 109.42;

[0065] The second supplier: reputation score XF22 = 97; product score CF22 = 93; number of product types CS22 = 3; then the evaluation coefficient PX22 = 108.86;

[0066] The third supplier: reputation score XF23=96; product score CF23=92; number of product types CS23=6; then the evaluation coefficient PX23=113.46.

[0067] Divide several suppliers into a group according to the component name to obtain several groups of suppliers; sort the suppliers in the several groups from large to small according to the evaluation coefficients to obtain a supplier ranking table corresponding to each group; select the supplier ranked first from the supplier ranking table, and integrate several suppliers to obtain the final supplier.

[0068] For example: suppose the suppliers of component 2 are sorted from large to small according to the evaluation coefficient, and the supplier ranking table obtained is supplier 3, supplier 1, supplier 2; then supplier 3 is selected as the final supplier of component 2.

[0069] See also Figure 3 , obtain the time of sub-projects in the engineering project from the database, calculate the average time of the same sub-project, and use the average time as the basis for division; obtain the engineering sequence of the sub-projects, sort the average time according to the engineering sequence to obtain several project cycles corresponding to the engineering project.

[0070] For example: Assume that sub-projects A, B, and C are divided, and the average time of the sub-projects is calculated to be 2 months, 1 month, and 1.5 months;

[0071] The sub-projects are arranged in order: sub-project A takes 2 months to construct, sub-project B takes 1 month to construct, and sub-project C takes 1.5 months to construct.

[0072] Obtain product information of several components, retrieve several project cycles and corresponding sub-projects; match product information with sub-projects to obtain project product tables corresponding to several sub-projects; and divide product information in the project product table into corresponding project cycles according to the project cycles corresponding to the sub-projects.

[0073] For example: suppose that the products of sub-project A and sub-project B are matched, and the matching components of sub-project A are components 3, 7, 8, 9, 10 and 11; the matching components of sub-project B are components 2, 6, 14 and 17; fill in the quantity, material and final supplier of the corresponding components into the project product table.

[0074] Retrieve product information corresponding to several project cycles, extract delivery information, match the delivery information with the product information to obtain a delivery matching table; before the start of a sub-project, determine whether all components of the sub-project have been delivered based on the delivery matching table. If so, analyze the next sub-project; if not, generate a procurement processing signal; detect the progress of the sub-project, and when the sub-project progress reaches the preset progress, determine whether all components of the next project cycle have been delivered based on the delivery matching table. If so, continue to detect the engineering progress; if not, generate a procurement processing signal.

[0075] For example: Assuming that the delivery of the product is checked before the start of sub-project A, and all components of sub-project A are delivered, then construction of sub-project A begins; when the construction reaches 1.8 months, the delivery of sub-project B is checked, and it is found that component 6 has not been delivered, then a procurement processing signal is generated.

[0076] Retrieve the procurement processing signal, and negotiate with the final supplier to set the delivery deadline based on the procurement processing signal; test the delivery deadline, and re-screen the suppliers when the final supplier fails to deliver within the delivery deadline.

[0077] For example: Assume that according to the procurement processing information, the delivery period of component 6 is negotiated to be set at 10 days with the final supplier. The delivery is checked on 10 days and it is found that the final supplier of component 6 has delivered the component. Then the delivery information of the sub-project is continuously checked.

[0078] Part of the data in the above formula is calculated by removing the dimension and taking its numerical value. The formula is a formula closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0079] Working principle of the present invention: The present invention obtains design drawings and parameters of the engineering project, and constructs a BIM model according to the design drawings and parameters; extracts component information from the BIM model, and generates a purchase list according to the component information; screens several suppliers according to the purchase list, obtains supply information of several suppliers, and calculates evaluation coefficients of several suppliers; screens out the final supplier from the suppliers based on the evaluation coefficient; obtains product information of several components, divides the engineering project into several project cycles, and matches product information with several project cycles; obtains delivery information of the final supplier's products; monitors the progress of the engineering project in real time to determine whether a new round of procurement is needed; if yes, generates a procurement processing signal; if not, continuously detects the progress of the engineering project; processes the product based on the procurement processing signal.
