[0002] In the prior art, the project cost list is usually prepared by qualified tenderers or project cost consultants and reviewed by auditors. The compilers rely on traditional pricing software to prepare the bill of quantities based on design drawings and relevant specifications. However, due to different compilation habits, there are differences in the lists of similar projects, and manual review and standardization processing consumes a lot of manpower and is inefficient.

[0003] In addition, the cost estimation tasks originate from the bidding documents and contracts of different owners. Due to different formats and requirements, cost estimation personnel need to manually match the scope and project quantity, which can easily lead to missing items, resulting in repeated revisions of the list, further reducing work efficiency. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the above-mentioned background technology and to provide a cost list generation system and method based on a standard list set, which can improve the completeness and accuracy of the project cost list structure to facilitate the matching and pricing of subsequent engineering quantities.

[0006] The standard list generation module is used to generate a standard list according to the externally imported list and instructions, and store the standard list in a designated hierarchical directory of the standard list collection module;

[0007] The standard list collection module is used to form a hierarchical directory according to different types of standards, costs and projects, and store the corresponding standard lists in the hierarchical directory;

[0008] The standard list display module is used to display the hierarchical directory of the standard list collection module, and import the standard list under the specified hierarchical directory into the cost list generation module according to external instructions;

[0009] The cost list generation module is used to display the lists imported into it, delete or add items in the standard list according to external instructions, and set price information and project quantities to generate a cost list.

[0010] The present invention provides a method for generating a cost list based on a standard list set, which adopts the cost list generating system based on a standard list set in the above technical solution, and comprises the following steps:

[0011] The standard list generation module generates a standard list and stores the standard list in a designated hierarchical directory of the standard list collection module;

[0012] The standard list collection module forms a hierarchical directory according to different types of standards, costs and projects, and stores the corresponding standard lists in the hierarchical directory;

[0013] The standard list display module displays the hierarchical directory of the standard list collection module, and imports the standard list under the specified hierarchical directory into the cost list generation module according to external instructions;

[0014] The cost list generation module displays the list imported into it, deletes or adds items in the standard list according to external instructions, and sets price information and project quantities to generate the cost list.

[0015] The beneficial effects of the present invention are as follows: the method of the present invention relies on the collection of standard lists, so that cost personnel can quickly compile project lists, which is convenient for the matching and pricing of later engineering quantities and effectively improves work efficiency.

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0030] Example 1

[0031] like Figure 1 As shown, the present invention provides a cost list generation system based on a standard list collection, including a standard list generation module, a standard list collection module, a standard list display module, and a cost list generation module;

[0032] The standard list generation module is used to generate a standard list according to the externally imported list and instructions, and store the standard list in a designated hierarchical directory of the standard list collection module;

[0033] The standard list collection module is used to form a hierarchical directory according to different types of standards, costs and projects, and store the corresponding standard lists in the hierarchical directory;

[0034] The standard list display module is used to display the hierarchical directory of the standard list collection module, and import the standard list under the specified hierarchical directory into the cost list generation module according to external instructions;

[0035] The cost list generation module is used to display the lists imported into it, delete or add items in the standard list according to external instructions, and set price information and project quantities to generate a cost list.

[0036] Specifically, the user can directly import the completed cost list file into the standard list generation module as a standard list and associate it to the hierarchical directory of a selected standard list collection module. Alternatively, the user can associate the cost list currently generated in the cost list generation module as a standard list to the hierarchical directory of a selected standard list collection module. The last level of the hierarchical directory of the standard list collection module can correspond to multiple standard lists. The present invention can continuously optimize the standard list library as data accumulates.

[0037] Specifically, it also includes a historical list generation module, which is used to store historical cost lists and import the specified historical cost lists into the cost list generation module according to external instructions; the cost list generated by the cost list generation module is automatically stored in the historical list generation module as a historical cost list.

[0038] Preferably, during use of the present invention, if the cost estimator already knows that the current project is similar to a previous project, the cost list of the previous project can be directly called from the historical list generation module and opened through the cost list generation module. The user can adaptively modify the existing cost list to generate a cost list for the current project. The process is simple and efficient, which greatly improves work efficiency.

[0039] Preferably, the historical list generation module has a query function, and cost estimators can locate the cost lists of past engineering projects through keyword searches, thereby effectively improving work efficiency.

[0040] Specifically, the cost list generation module is also used to generate the cost list name and determine the project type according to external instructions; the standard list display module selects and displays the corresponding hierarchical directory according to the determined project type.

[0041] Preferably, the user selects the project type by inputting instructions, and the standard display module selects and displays the graded catalog that meets the selected project type according to the input instructions, thereby improving the efficiency of the user's search and browsing of the total collection catalog. The user can also select the cost type by inputting instructions, such as bidding cost analysis, cost target, construction drawing budget, subcontract settlement, etc. The selected cost type is marked in the system to characterize the cost stage and is used for the user to distinguish the cost list later, but is not used for subsequent catalog division.

[0042] Preferably, the user can continuously pull down the hierarchical directory through external input commands to locate the standard list applicable to the current project. The user can import multiple standard lists into the cost list generation module for display, thereby providing the user with a variety of choices to ensure that the generated cost list meets the user's current needs.

[0043] Specifically, it also includes a unit price analysis module, which is used to generate reference price information of any item in the cost list currently produced by the cost list generation module based on the price information of the specified item in the specified historical cost list or the standard list and the set engineering quantity information;

[0044] The cost list generation module calls the reference price information corresponding to the project in the unit price analysis module as the set price information display.

[0045] Preferably, according to external instructions, for a certain project in the list currently made by the cost list generation module (the project has been set with the corresponding engineering quantity), the unit price analysis module is started; the unit price analysis module selects several projects in the historical cost list or the standard list according to the external instructions and sets the corresponding engineering quantity to correspond to the engineering quantity of the currently selected project in the cost list generation module. The underlying logic of this operation is: a certain project in the current production list that has set the engineering quantity can be disassembled into a combination of several projects in the historical cost list or the standard list according to the set engineering quantity. Therefore, by calculating the total price of several set engineering quantity projects in the historical cost list or the standard list, the total price of a certain project in the current production list that has set the engineering quantity can be obtained, thereby obtaining the unit price of the project in the current production list. The unit price analysis module can draw on past experience and combine actual needs to obtain the reference unit price of a single project, improve work efficiency, and ensure the rationality of price setting.

[0046] Specifically, it also includes an information price module, which is used to form an information price file according to a specified historical cost list or a standard list; the information price file includes items and their corresponding unit price information prices; when there are identical items in multiple specified lists, the average unit price of the item in multiple lists is used as the unit price information price of the item;

[0047] The cost list generation module calls the specified information price file in the information price module and displays the information price corresponding to the items of the cost list currently being produced.

[0048] Preferably, the user can use external input instructions to start the cost list generation module to generate the cost list name and determine the project type, and use the information price module to associate the currently produced cost list with the specified information price file.

[0049] The user can also directly start the information price module through external instructions, and then call the specified historical cost list or standard list according to the external instructions. The information price module automatically extracts the items in the specified list and their corresponding unit price information to form an information price file. After the information price file is generated, it can display the highest and lowest prices, average prices, median prices and other related information and conclusions, which is convenient for cost personnel to provide reference information without having to review previous materials, effectively improving work efficiency. When the cost list generation module calls the information price file from the information price module, it only uses the crawler function to search for the information price of each item in the current cost list in the information price.

[0050] If the user does not specify the information price file through the information price module when starting the cost list generation module, the information price will not be displayed.

[0051] Alternatively, if a certain item and its price information do not exist in the specified information price file, the information price of the item will not be displayed. The present invention further provides price information guidance for the cost list currently being produced through the information price module integrated standard list collection and historical list, and provides users with effective historical data support.

[0052] Specifically, it also includes a cost comparison module, which is used to form and display comparison details and comparison summaries for designated historical cost lists according to external instructions; the comparison details include the differences in project quantities, unit prices and total prices between designated historical cost lists; the comparison summary is a conclusion on the causes of the differences generated from matters, project quantities and unit prices based on the comparison details.

[0053] Preferably, the user can view the existing historical cost lists and standard lists of the standard list collection module and the historical list generation module through the cost comparison module. The user inputs instructions to select at least two historical cost lists and standard lists. The cost comparison module obtains the consistent items and their price information in the selected lists through the crawler function, and compares the price, engineering quantity and cost differences of the same items in different lists to form a comparison conclusion. At the same time, the overall items and price differences between the two lists are compared, and the reasons for the differences are analyzed from multiple dimensions, providing users with diversified analysis conclusions and realizing effective cost list comparison analysis.

[0054] Since both the historical cost list and the standard list use the same standardized template for project names and layout, the cost comparison module can efficiently and accurately obtain comparison conclusions, making it easier to provide reference opinions for users.

[0055] Specifically, it also includes a template management module, which is used to generate and store a templated cost list (hereinafter referred to as the template list) according to external instructions, and import the specified templated cost list into the cost list generation module according to the external instructions.

[0056] Preferably, the user can customize the templates of subdivided types through the template management module, and directly import the template list into the cost list generation module when compiling the cost list, thereby effectively improving work efficiency.

[0057] Specifically, the hierarchical catalog of the standard list module includes an engineering classification catalog and a standard classification catalog; among which:

[0058] The first-level catalog of the project classification catalog is classified according to the project type, and the second-level catalog is classified according to the full-caliber cost components of each project. The second-level catalog is classified in turn according to the different projects or cost items under each cost component; the last level of the project classification catalog corresponds to at least one standard list;

[0059] The first-level directory in the standard classification directory is classified according to project type, the second-level directory is classified according to different standards under each project type, and the third-level directory is a standard list corresponding to each standard.

[0060] like Figure 2 As shown, when the first-level catalog is an EPC general contracting project, the cost structure is based on the process flow of wind power generation and photovoltaic power generation, and refers to the actual budget preparation regulations and cost standards for photovoltaic / onshore wind farm projects, and is sorted and classified in combination with the company's own cost structure characteristics. First, the full-caliber cost structure elements of the general contracting project are formed vertically, and then the costs are decomposed horizontally from three levels: unit project, sub-project, and list: the full-caliber cost structure includes five parts, namely construction and installation project costs, equipment and material procurement costs, consulting services and other fees, enterprise cost costs, and provisional funds / provisional estimates; the second-level projects in the cost decomposition can refer to the actual budget preparation regulations and cost standards for photovoltaic / onshore wind farm projects.

[0061] Preferably, the present invention can efficiently realize the cost list preparation of new energy projects. Due to the particularity of new energy projects, its subdivision projects are cumbersome and complex, but the construction content of a single project is clear as a whole.

[0062] Furthermore, through the unit price analysis module of the present invention, the construction content of a single project in a new energy project can be effectively and reasonably disassembled, and the corresponding sub-items and their corresponding prices can be called from the historical cost list or the standard list to form a reference unit price for a single project, thereby improving work efficiency while ensuring the rationality of the unit price setting.

[0063] Furthermore, due to the standardized design of new energy projects, the price information module can be used to efficiently and intuitively reference the prices in the previous list, without the need for users to look up materials for inquiries. At the same time, users can also continuously update the price information file based on the continuously generated new cost list, so that the system is continuously optimized.

[0064] Furthermore, the cost comparison module can realize the specific cost comparison of different new energy projects, providing effective data support for the subsequent work of cost estimators.

[0065] Furthermore, due to the cumbersome construction content of new energy projects, the projects involved in a single project may cover multiple independent unit projects. By setting template lists for different unit projects in the template management module, the template list can be used first when compiling the cost document, effectively improving the efficiency of making the cost list.

[0066] Specifically, it also includes a user information module, which is used to store and verify the user's account and password and their permissions, and open the use permissions to the verified users; the use permissions include editing, merging and reviewing the cost list under the corresponding permissions;

[0067] It also includes a permission association module for associating the cost list with the editing, merging and reviewing permissions of the user according to external instructions;

[0068] It also includes an audit module, which is used to display the cost list under the user's audit authority and receive the audit conclusion from the user, and display the audit conclusion of the cost list under the user's editing authority;

[0069] It also includes a file merging module for merging the cost lists under the user's merging authority to generate a new cost list according to external instructions.

[0070] Preferably, the user enters the account number and password through the login interface, and the user information module receives the account number and password entered by the user and verifies them. For users who pass the verification, they are adjusted to the operation interface. The present invention sets corresponding permissions to ensure that only specific users can edit specific cost lists, thereby ensuring the assistance and management effectiveness of the cost list compilation process.

[0071] After completing the preparation of the cost list, the user can automatically jump to the associated interface of the review authority by clicking the corresponding button in the operation interface, and enter instructions in the associated interface of the review authority, and the instruction content includes the reviewer information. The authority association module receives the reviewer information and opens the review authority of the cost list to the reviewer, that is, adjusts the use authority information of the reviewer in the user information module.

[0072] After completing the preparation of the cost list, the user can also automatically jump to the associated interface of the merged authority by clicking the corresponding button in the operation interface, and enter instructions in the associated interface of the merged authority, and the instruction content includes the merged personnel information. The authority association module receives the merged personnel information and opens the merged authority of the cost list to the merged personnel, that is, adjusts the use authority information of the merged personnel in the user information module.

[0073] After the user logs into the system, he can view the audit conclusions of the cost list to be audited, the cost list that has been audited, and the cost list submitted for audit through the audit work interface.

[0074] At the same time, different users can make cost lists for different sub-items of the same project, and then start the file merging module to view all the cost lists that can be merged within the scope of the merging authority. By selecting multiple specified cost lists, they can be merged into an overall cost list.

[0075] The present invention ensures that the comparison, preparation, merging and review of the cost list can be achieved in the same system through process-based authority setting, thereby effectively improving the work efficiency of the cost process.

[0076] The specific use process of the present invention is further described below in conjunction with specific embodiments.

[0077] The user enters his / her personal account and password on the system login page and enters the operation page after verification. The user can view the cost list directory that can be edited, merged and reviewed under the user's authority through the operation page, and can perform editing, merging or reviewing operations by clicking the corresponding cost list name.

[0078] The standard list collection module in the system background has stored the standard list collection. Figure 3 As shown, the user can jump out of the input command dialog box by clicking the "New" button in the operation interface.

[0079] The user enters the basic information of the cost file in the command dialog box: the customized cost list name, the selected cost type and the standard total list (that is, select the corresponding project type); select "Information Price File"; start the template management module by clicking "Template" to quickly reference the established template list.

[0080] Among them, "cost type" is divided according to the stage of cost document formation, such as bidding cost analysis, cost target, construction drawing budget, subcontract settlement, etc. Corresponding labels are generated according to the selected cost type to mark the cost type of the final generated cost list.

[0081] Based on the selected "Standard Total List", the hierarchical catalog, template list and information price file displayed in the standard list display module are simplified to only display the hierarchical catalog, template and information price file of the selected project type. The template list and information price file will be marked with the corresponding project type when they are produced.

[0082] like Fig. 9 As shown, click "Template" to start the template management module, and a dialog box for the optional template list corresponding to the selected "Standard General List" type will appear on the page. Fig.10 As shown in the figure, click "Information Price File" to start the information price module, and a dialog box for optional information price files corresponding to the selected "Standard General List" type will appear. After checking the corresponding file, click OK to return to the Figure 3 The page shown.

[0083] After completing the command dialog box, click "OK" to start the cost list generation module and jump to the cost list compilation page. Figure 4 In this specific embodiment, the cost type is selected as the cost target; the standard total list (i.e., the corresponding project type is selected) is selected as the power project. In this embodiment, no template list is selected.

[0084] The standard list display module calls the corresponding hierarchical directory and the corresponding forms under the directory in the standard list collection module based on the selection of "Power Engineering", and displays them on the left side of the cost list preparation page.

[0085] The user can locate the last level of the standard form by pulling down the hierarchical directory on the left side of the cost list preparation page, and add the standard form to the cost list preparation page.

[0086] Alternatively, the user can start the historical list generation module through the "Import" button, locate a historical cost list similar to the current project through retrieval, lead it to the cost list generation module, and then display it through the cost list compilation page.

[0087] Alternatively, the user can start the template management module through the "Template" button and import the template list.

[0088] Users can add items based on the imported list to meet current needs.

[0089] Based on the currently edited cost list, the user can click the "one-click clear engineering quantity" button to uniformly delete the engineering quantity data in the current form, and the "one-click clear unit price" button to uniformly delete the unit price data in the current form.

[0090] The information price module automatically fills in the information price according to the project information written in the current form based on the selected information price file.

[0091] After setting the engineering quantity for any item in the list, you can click the icon in the corresponding "Unit Price Analysis" column to start the unit price analysis module. Figure 5 As shown in the figure, after starting the unit price analysis module, click "Add List Item" in the pop-up dialog box to select the historical cost list or the standard list. Figure 6 As shown in the figure, further select reference items for unit price analysis under the selected list. Figure 7 As shown, you can select several different reference items for unit price analysis under different lists, and set the engineering quantity of each reference item accordingly. The unit price analysis module obtains the total price of the selected item in the current cost form by summing the unit price and engineering quantity of each reference item, divides it by the set engineering quantity, obtains the reference unit price of the selected item, and automatically fills it into the unit price column. Users can manually modify the filled unit price information.

[0092] Users can set the unit price of each item based on the conclusions displayed by the unit price analysis module and the information price module. After confirming that all items have been added and all quantities and unit prices have been set, you can click the "Calculate and Save" button at the bottom of the cost list compilation page to generate the cost list.

[0093] After the user verifies that the cost list is correct, he or she can set the reviewer for the cost list.

[0094] like Fig.11 As shown in the figure, the user can click the "Cost File Comparison" button on the main page to start the cost file comparison module. The main page automatically pops up a dialog box. Under the selected "Standard Total List", further select the historical cost list of the "Power Engineering" type. The cost file comparison module automatically generates the following according to the selected historical cost list: Fig.12 Comparative data shown.

[0095] like Fig.13 As shown, the user can click the "Cost File Merge" button on the main page to start the cost file merge module. The main page automatically pops up a dialog box, and under the selected "Standard Total List", further select the historical cost list of the "Power Engineering" type. The cost file comparison module automatically generates a merged cost list based on the selected historical cost list.
