[0045] Various exemplary embodiments, features and methods of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0046] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0047] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0048] <Method Example>

[0049] It should be noted here that before executing the method disclosed in the present invention, a case library consisting of real engineering cost cases needs to be constructed first, so that cost indicators can be generated based on the large number of real engineering cases accumulated in the case library.

[0050] When building a case library, the data entry function of the system based on the execution of the method disclosed in this disclosure is implemented. Specifically, a data entry control is set in the system interface. When the data entry control is triggered, the push display is as follows: Figure 1 The case entry interface shown in the figure has selection controls such as engineering category selection control, cost stage selection control, consulting work attribute selection control, case classification selection control, and case belonging to the same project name search selection control.

[0051] When the project category selection control is triggered, the project category list will be pushed and displayed. The project category list includes multiple pre-divided project categories, and each project category is refined and classified to obtain multiple divided project categories. The user can select the project category to which the input case belongs in the project category list. When any project category in the project category list is selected, the selected project category is set as the project category of the input case.

[0052] When the cost stage selection control is triggered, the following will be pushed: Figure 2 The cost stage list shown in the figure. The cost stage list includes five cost stages: estimation, budget estimate, budget, settlement and final settlement. Each cost stage is divided into multiple types. Among them, the estimation stage is divided into six types: project proposal, proposal instead of feasibility study, feasibility study report, project application report, funding application report and implementation plan. The budget estimate stage is divided into four types: project application report, funding application report, implementation plan and preliminary design budget estimate. The budget stage is divided into four types: construction drawing budget, bidding control price, bidding quotation and contract price. One type of completion settlement is set for the settlement stage. One type of project final settlement is set for the final settlement stage. The user can select the cost stage and type to which the case to be entered belongs in the cost stage list. If any cost stage and type in the cost stage list is selected, the selected cost stage and type will be set as the cost stage of the entered case.

[0053] The consulting work attribute selection control includes two sub-selection controls: compilation and evaluation. Users can choose compilation and evaluation based on the actual situation of the entered case.

[0054] The case classification selection control includes a storage project selection sub-control. When the storage project selection sub-control is selected, the subsequent case storage function can be realized.

[0055] When the search selection control for cases belonging to the same project name is triggered, you can query the project names of all cases stored in the database. If the case being entered already has related cases stored in the database, you need to select the corresponding project name from the project names of the stored cases as the project name of the case being entered to ensure that the same projects stored in the database have a unified project name.

[0056] The user can enter the case's engineering category, cost stage, consulting work attributes, case classification type, and project name through the case entry interface. After completing these settings, click the Next control to push out the project feature entry interface that matches the entered engineering category and cost stage. The project feature entry interface is as follows: Figure 3 As shown, it includes multiple project features and corresponding cost data structures set for the project category and cost stage. Users can enter the various project features of the case through the project feature entry interface. Among them, the project features include at least one of common features, category features and entity features. The common features refer to the information that all project categories have, and their database table structures should be consistent. Category features refer to the features that a certain project category has, and entity features refer to the individual features of specific projects. For example, when the project category is kindergarten, the common features may include project category, project name, construction site, project location, construction stage, construction nature, construction content, construction scale, approval department, approval time, source of funds, name of construction unit, name of consulting unit, name of design unit, name of consulting unit, name of consulting unit project manager, mobile phone number of consulting unit project manager, contracting method, project start time, project completion time, industry, information price location, pricing base time and other features; category features may include school scale (classes), construction land Characteristics such as area (m2), floor area ratio, greening rate (%), assembly rate (%), total construction area (m2), green building standards, seismic fortification intensity, geological conditions, and civil air defense level; entity characteristics may include single building area (m2), number of above-ground floors, number of underground floors, above-ground floor height, underground floor height, structure type, foundation engineering, foundation pit support method, roof engineering, wall engineering, floor engineering, door and window engineering, ceiling engineering, water supply and drainage engineering, fire protection engineering, heating engineering, air conditioning engineering, ventilation engineering, electrical engineering, building intelligent engineering, gas engineering, and supporting equipment.

[0057] After completing the project feature entry of the case, you can enter the cost result file entry interface. The cost result file entry interface includes a file upload control, through which users can upload the engineering drawings of the case. When the engineering drawings are uploaded, the API interface of the cost software will be called. When the API interface of the cost software is called, the engineering cost result file of the case will be output according to the engineering drawings of the case, and the output engineering cost result file will be linked to the cost result file entry interface.

[0058] After the cost results file of the entered case is linked to the cost results file entry interface, the system will be triggered to obtain the standard data structure table that matches the entered engineering category and cost stage, and match the project characteristics of the entered case and the information in the cost results file to the corresponding fields in the standard data structure table, so that the entered case will be stored in the form of a standard data structure table.

[0059] By referring to the above steps, a large number of real engineering cost cases collected can be stored in the database, forming a case library with a standard data structure table including many real cases. It should be noted that a large number of real cases will be continuously entered during the use of the system, so as to realize the continuous updating of cases in the case library.

[0060] After the case library is constructed, the cost indicator generation method disclosed in the present invention can be executed.

[0061] Figure 4 A flow chart showing a method for generating a cost index of a project cost according to an embodiment of the present disclosure is shown. Figure 4 As shown, the method includes steps S1100-S1400.

[0062] S1100, obtaining the project characteristics and various cost items of the project to be priced, wherein the project to be priced is the project to be priced currently.

[0063] In a possible implementation, when obtaining the project characteristics of the project to be priced, the following steps may be included:

[0064] First, the engineering category and cost stage of the engineering to be costed are obtained. Specifically, an index query control is provided in the system for executing the disclosed method. When the index query control is triggered, the following information will be pushed: Figure 5 The indicator query interface shown in the figure has a project category selection control and a cost stage selection control. The project category and cost stage of the project to be costed can be set through the project category selection control and the cost stage selection control of the interface. The specific setting method is described above and will not be repeated here. After completing the setting of the project category and cost stage of the project to be costed, the system can obtain the project category and cost stage of the project to be costed.

[0065] Second, based on the engineering category and cost stage of the project to be priced, push and display the project feature configuration area that matches the project to be priced. Specifically, after obtaining the engineering category and cost stage of the project to be priced, Figure 5 The bottom of the indicator query interface shown pushes and displays the project feature configuration area that matches the project to be costed. The project feature configuration area includes project feature fields that match the project category and cost stage of the project to be costed. Users can set multiple key project features of the project to be costed through the project feature configuration area to facilitate subsequent target case screening. Among them, project features also include three categories of project features: general features, category features, and entity features.

[0066] Third, based on the project feature configuration area displayed by the push, the project features of the project to be priced are obtained. Specifically, after the user configures the project features of the project to be priced in the project feature configuration area and clicks query, the system can obtain the project features of the project to be priced.

[0067] In a possible implementation, when obtaining each cost item of the project to be priced, the following steps may be included:

[0068] First, the project category and cost stage of the project to be costed are obtained. Specifically, the acquisition process is as described above and will not be repeated here.

[0069] Second, based on the project category and cost stage, obtain the various cost items of the project to be costed. Specifically, it should be noted that a mapping relationship table including project category, cost stage and corresponding cost items is pre-stored in the system, and the cost items corresponding to the project category and cost stage of the project to be costed can be obtained by querying the mapping relationship table. The cost items corresponding to the project category and cost stage of the project to be costed are the cost items of the project to be costed.

[0070] After obtaining the project characteristics and various cost items of the project to be priced, step S1200 may be executed to filter out target cases matching the project to be priced from a pre-built case library based on the project characteristics.

[0071] In a possible implementation, when selecting a target case matching the project to be costed from a pre-built case library based on project characteristics, the following steps may be included:

[0072] First, obtain the pre-configured query conditions. Specifically, in Figure 5The indicator query interface shown also has a query condition configuration area. The user can configure the required query conditions in the query condition configuration area. After the query condition configuration is completed, click Submit and the system can obtain the pre-configured query conditions. The query conditions may include at least one of the characteristic numerical type allowable deviation, pricing benchmark time deviation, construction site co-level, and the number of cases expected to participate in the statistics.

[0073] Second, select the cases that meet the project characteristics and query conditions from the case library as the initial target cases. Figure 6 The target case display interface shown. In the first area of ​​the target case display interface (i.e. Figure 6 The filter similar cases area shown in the figure displays the project features and query conditions for filtering the initial target cases, and identifies the degree of match between each initial target case and the project features and query conditions. Specifically, when the initial target case meets the project features and query conditions, a check mark is marked at the position corresponding to the project features and query conditions. When the initial target case does not meet the project features and query conditions, a difference mark is marked at the position corresponding to the project features and query conditions. In this way, the user can clearly see the match between each initial target case and each project feature and query condition. The second area of ​​the target case display interface (i.e. Figure 6 The similar cases list that meets the filtering conditions shown in the figure displays a list of multiple initial target cases that currently meet the conditions.

[0074] Third, obtain the project characteristics that must be met, and select the cases that meet the project characteristics that must be met from the initial target cases as the target cases that match the project to be costed. Figure 6 In the first area shown, there are click controls for project features and query conditions. When any project feature or query condition is selected, the selected project feature or query condition is used as a project feature that must be met. After obtaining the project features that must be met, the cases that meet the project features that must be met are further selected from the initial target cases as target cases that match the project to be costed, and the target cases displayed in the first area and the second area are updated.

[0075] In a possible implementation, after the target cases matching the engineering items to be priced are screened out, the method further includes: selecting a final target case that meets the user's needs from each target case. Specifically, a selection box is provided in front of each target case displayed in the second area of ​​the target case display interface. When the selection box in front of any target case is selected, it is screened out as the final target case.

[0076] In this embodiment, the user can first filter out the initial target cases by project features and query conditions, and then further filter out the target cases by setting the project features that must be met. Finally, the user can further filter out the final target cases from the target cases according to their own needs, thereby meeting the user's case screening requirements of different granularities.

[0077] After the target case is screened, step S1300 may be executed to determine the penetration stages of each expense item, and calculate the reference expense index of each expense item in each penetration stage based on the target case.

[0078] In a possible implementation, when determining the stages through which each cost item passes, it is implemented based on the through labels of each cost item, wherein the through labels are used to identify the cost stages through which the cost item passes, and the measurement standards for the through stages are unified.

[0079] The penetration label includes full penetration label, partial penetration label and non-penetration label. When the penetration label is a full penetration label, it indicates that the measurement standards of the cost items in the estimation, budget estimate, budget, settlement and final settlement are unified, and the corresponding penetration stages are the five cost stages of estimation, budget estimate, budget, settlement and final settlement. When the penetration label is a partial penetration label, it indicates that the measurement standards of the cost items in some cost stages are unified, and the corresponding label will identify the specific cost stage it penetrates. When the penetration label is a non-penetration label, it indicates that the measurement standards of the cost items in each cost stage are not unified, and the corresponding penetration stage is only the current cost stage.

[0080] When setting the through-label of each cost item, it is implemented based on the keywords of each cost item. Specifically, after determining the cost item corresponding to the project category and the cost stage, the keywords of the cost item will be obtained. If the cost item exists in all cost stages and the keywords in all cost stages are consistent, the through-label of the cost item is determined to be a full-through label. If the cost item exists in some cost stages and the keywords in some cost stages are consistent, the through-label of the cost item is determined to be a partial-through label, and the cost stages it runs through are recorded. If the cost item only exists in the current cost stage, the through-label of the cost item is determined to be a non-through label. Among them, the keywords include the name of the cost item, the unit of measurement, and the remarks. The unit of measurement identifies the caliber of measurement, and the remarks are used to record the work content. If the keywords are consistent, it means that the statistical caliber of the cost item in each cost stage is consistent. Since the statistical caliber of the cost items in each cost stage is consistent, they are comparable.

[0081] After determining the labels of each expense item, the reference expense indicators of each expense item in each stage can be calculated based on the target case. Figure 7For each stage of the cost item, extract the cost item value of the current stage from each target case, and calculate the maximum value, arithmetic mean, median, concentrated distribution value and minimum value of each value, and use the calculated maximum value, arithmetic mean, median, concentrated distribution value and minimum value as the reference cost index of the cost item in the current stage. By referring to the above steps, the reference cost index of each stage can be obtained.

[0082] For example, if the stages of cost item A are estimation and budgeting, then first for the estimation stage, read the value of cost item A in the estimation stage of each target case and calculate the maximum, arithmetic mean, median, concentrated distribution value and minimum value as the reference cost index of cost item A in the estimation stage. Then, read the value of cost item A in the budgeting stage of each target case and calculate the maximum, arithmetic mean, median, concentrated distribution value and minimum value as the reference cost index of cost item A in the budgeting stage. In other words, for cost item A, 5 reference cost indexes for the estimation stage and 5 reference cost indexes for the budgeting stage will be obtained.

[0083] S1400, based on the reference cost index of each cost item in each penetration stage, generate the cost index of each cost item in the current cost stage. Specifically, based on the reference cost index of each cost item in each penetration stage, generate a data statistical chart including the reference cost index of each penetration stage (specifically, Figure 8 As shown on the right, users can clearly understand the reference cost indicators in each stage through the data statistics chart, and then select the reference cost indicators that meet the requirements of the investment system from the data statistics chart as the cost indicators of the current cost stage. By default, the median of the reference cost indicators corresponding to the current cost stage can be used as the cost indicator of the current cost stage.

[0084] The present disclosure provides a method for generating cost indexes of engineering cost, including: obtaining project characteristics and various cost items of the engineering to be priced; selecting target cases matching the engineering items to be priced from a pre-built case library based on the project characteristics; determining the run-through stages of each cost item, and calculating the cost index of each cost item in each run-through stage based on the target case; generating the cost index of each cost item in the current cost stage based on the cost index of each cost item in each run-through stage. The method disclosed in the present disclosure can refer to the cost index of each cost stage to determine the cost index of the current cost stage, so that the cost index of the current cost stage will not exceed the cost index of the previous cost stage, and thus the cost result meets the requirements of the investment system.
