Description

Technical Field

[0001] The present invention relates to the technical field of engineering project analysis, and in particular to a method and system for fully intelligently analyzing engineering project investment and progress deviations. Background Art

[0002] In engineering construction, investment and progress are two very important factors that have a crucial impact on the success of a project. The actual progress and investment completion of an engineering construction project are respectively summarized from the completion of various work tasks and the settlement of various subcontracts. These belong to two different dimensions. Based on the apparent progress of the construction project, the completion status can only be roughly estimated and roughly compared with the investment settlement. There are no conditions for direct and accurate comparison. In the event of deviations, it is also impossible to intuitively analyze the specific links where the deviations occurred, making it difficult to achieve precise control and detrimental to the refined management and control of the project. In actual operations, the inability to accurately compare the actual progress of the project with the investment completion status often leads to the inability to detect and correct deviations in investment and progress in a timely manner, thus causing financial risks to the project. Therefore, how to accurately compare and analyze the investment and progress of engineering construction projects and locate deviations has always been an urgent problem to be solved in the field of engineering construction.

[0003] Therefore, the present invention provides a method and system for fully intelligent analysis of engineering project investment and schedule deviations. Summary of the Invention

[0049] The present invention provides a fully intelligent system for analyzing project investment and schedule deviations, comprising:

[0050] A project decomposition module is used to perform PBS decomposition on the construction contract to obtain several cost items of the project, and to perform WBS decomposition on the construction contract to obtain several checklist items of the project;

[0051] A cost allocation module is used to match each cost item with a corresponding checklist item, and to establish a planned cost amount corresponding to each construction progress stage of the project according to the project task corresponding to each checklist item;

[0059] The fourth verification unit is used to allocate the actual cost amount to each of the constructed progress, obtain the cost amount corresponding to each of the constructed progress, establish a budget item corresponding to each of the constructed progress, correct the budget amount of the corresponding budget item according to the construction amount of the current progress corresponding to the current construction progress, and generate a valid budget item for the current construction progress.

[0060] The above technical solution has the following beneficial effects: in order to uniformly quantify investment data and progress and resolve the problem of progress data and investment data belonging to two different dimensions, the cost items and checklist items of the construction project are determined by decomposing the construction contract. This realizes that the project PBS is used as the basic unit, the contract settlement data is used as the actual project cost, and the cost baseline is used as the link to allocate it to each project PBS. Then, based on the matching relationship between the cost items and checklist items, the planned cost amount corresponding to each construction progress stage of the project is estimated. Therefore, during actual construction, the actual cost amount of the current construction progress is determined based on the current construction progress and the progress performance index, and the estimated cost item of the current construction progress is constructed. The current cost deviation amount is obtained by uniformly analyzing the estimated cost items, and finally the remaining cost amount is reallocated. This solves the problem of inconsistent comparison basis in traditional technologies, and also realizes accurate comparative analysis and accurately locates the links with large deviations. It can promote the refined management of investment and progress of construction projects. It can also reallocate limited cost amounts according to actual conditions, improve the clarity of capital investment, and avoid unidentified expenditure.

[0061] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

[0066] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0067] Example 1

[0068] This embodiment provides a method for fully intelligently analyzing the deviation between project investment and schedule. Figure 1 Shown, including:

[0069] Step 1: Decompose the construction contract by PBS to obtain several cost items of the project, and decompose the construction contract by WBS to obtain several list items of the project;

[0070] Step 2: Match each cost item with a corresponding checklist item, and establish the planned cost amount for each construction progress stage of the project based on the project tasks corresponding to each checklist item;

[0071] Step 3: Determine the actual cost amount corresponding to the current construction progress based on the current construction progress and the progress performance index of the project, and generate a budget estimate corresponding to the current construction progress;

[0072] Step 4: Analyze the current cost deviation of the project based on several budget items of the project, and make cost adjustments for each unfinished construction progress stage.

[0073] In this example, PBS decomposition represents the process of breaking down a construction contract into projects, and WBS decomposition represents the process of breaking down a construction contract into work tasks.

[0074] In this example, the cost item represents the capital expenditure of this project;

[0075] In this example, the checklist items represent the activities that need to be performed to complete this engineering project;

[0076] In this example, a cost item can match one or more list items;

[0077] In this instance, a project task represents the execution task targeted by a checklist item;

[0078] In this example, the progress performance index represents the performance of the current construction progress and the performance value corresponding to the performance;

[0079] In this example, the actual cost amount represents the cost consumed to complete the current construction progress;

[0080] In this instance, cost adjustment represents the process of reallocating the remaining cost budget;

[0081] In this example, the budget item represents the cost plan for the current construction progress.

[0082] The working principle and beneficial effects of the above technical solution are as follows: In order to uniformly quantify investment data and progress and resolve the issue of progress data and investment data belonging to two different dimensions, the cost items and checklist items of the construction project are determined by decomposing the construction contract. This implements the project PBS as the basic unit, using contract settlement data as the actual project costs, and allocating them to each project PBS based on the cost baseline. Then, based on the matching relationship between cost items and checklist items, the planned cost amount corresponding to each construction progress stage of the project is estimated. During actual construction, the actual cost amount of the current construction progress is determined based on the current construction progress and the progress performance index, thereby establishing an estimated cost item for the current construction progress. By uniformly analyzing the estimated cost items, the current cost deviation amount is obtained, and finally, the remaining cost amount is reallocated. This not only solves the problem of inconsistent comparison bases in traditional technologies, but also enables accurate comparative analysis and accurately locates links with large deviations, promotes the refined management of investment and progress of construction projects, and can also reallocate limited cost amounts according to actual circumstances, improving the clarity of capital investment and avoiding unidentified expenditures.

[0083] Example 2

[0084] Based on Example 1, the method for fully intelligently analyzing project investment and progress deviations, step 1, includes:

[0085] Step 11: Perform PBS decomposition on the project construction contract to obtain several construction items of the current engineering project, construct the project cost composition of the current engineering project based on the project construction contract, and determine the construction cost corresponding to each construction item based on the project cost composition;

[0086] Step 12: Establishing several cost expenditures corresponding to the current engineering project based on the project cost composition, and determining several expenditures corresponding to each construction project in combination with the construction cost corresponding to each construction project, thereby generating several cost items for the current engineering project;

[0087] Step 13: Establish project planning tasks corresponding to each of the construction projects according to the construction contract, perform WBS decomposition on the project planning tasks to obtain several independent tasks corresponding to each of the construction projects, and generate several checklist items for the current project based on the basic task requirements corresponding to each of the independent tasks.

[0088] In this example, the project cost components represent the allocation of investment costs for this engineering project;

[0089] In this instance, independent tasks represent complete tasks included in the construction project;

[0090] In this example, the task-based requirements represent the financial and transactional basis for executing independent tasks.

[0091] The working principle and beneficial effects of the above technical solution are as follows: the cost items and list items of this engineering project are determined by decomposing the project construction contract. During the decomposition process, the project cost composition of this engineering project is deeply analyzed to determine the cost expenditure and several independent tasks of this engineering project. In this way, the project construction contract can be refined to make the resulting cost items and list items more convincing.

[0092] Example 3

[0093] Based on Example 1, the method for fully intelligently analyzing project investment and progress deviations, step 2, includes:

[0094] Step 21: Create a bill of quantities measurement rule for the project based on the construction drawings of the project, and use the measurement rule to perform measurement decomposition on each bill item to obtain several bill of quantities and corresponding bill of quantities measurement methods corresponding to each bill item;

[0095] Step 22: Identify the cost measurement unit and the corresponding cost measurement method corresponding to each cost item, perform a first match between the list measurement unit and the cost measurement unit to obtain a number of adapted cost items corresponding to each list item, perform a second match between the adapted cost measurement method corresponding to the adapted cost item and the corresponding list measurement method to obtain a number of list items corresponding to each cost item, and construct a cost-list combination;

[0096] Step 23: Identify the drawing content corresponding to each checklist item in the construction drawing, semantically reorganize the drawing content, generate a project task corresponding to each checklist item, mark each project task in the construction drawing, and determine the task association relationship between different project tasks based on the marking results and basic parameters of the construction drawing;

[0097] Step 24: Establish several key task nodes based on the task association relationship to logically combine the checklist items, find the checklist items contained between adjacent key task nodes, establish the construction progress stage of the project, determine the cost information corresponding to each construction progress stage based on the cost-checklist combination, and generate the planned cost amount corresponding to each construction progress stage.

[0098] In this example, the list measurement rules represent the standardized measurement methods for list items for various projects, contracts, and procurement activities;

[0099] In this instance, measurement decomposition represents the process of identifying the inventory measurement units and inventory measurement methods of inventory items;

[0100] In this example, the unit of measurement indicates the unit of the item to which an expenditure corresponds, for example, one ton of cement, ten meters of protective netting, where "ton" and "meter" are the units of measurement;

[0101] In this example, the measurement method indicates the delivery and acceptance method of the item corresponding to an expenditure, for example: tiles need to be checked for completeness;

[0102] In this example, the purpose of the first matching is to narrow the matching range between cost items and inventory items and obtain several adaptation cost items that may match one inventory item;

[0103] In this example, the purpose of the second matching is to: determine the cost item corresponding to each list item;

[0104] In this instance, the project task represents the execution task corresponding to the checklist item;

[0105] In this instance, the task association relationship represents the causal relationship between different project tasks;

[0106] In this example, the task key node represents a task node generated by obtaining a complete result after completing one or more project tasks.

[0107] The working principle and beneficial effects of the above technical solution: In order to better match cost items and list items and avoid matching errors, the list measurement rules are first established according to the construction drawings, and the list items are measured and decomposed using the rules, and the list measurement method and list dosage unit corresponding to each list item are determined. Then, the cost items and list items are matched for the first time according to the cost measurement unit of the cost item, and a number of adaptive cost items corresponding to each list item are determined. Then, a second match is performed according to the cost measurement method to achieve accurate matching and generate a cost-list combination. By analyzing the task association relationship between different project tasks, the list items are logically combined to determine the construction progress stage of this project. Then, each cost-list combination is used to determine the cost information of each construction progress stage. Finally, the cost amount is allocated and the planned cost amount of each construction progress stage is determined. In this way, cost allocation can be performed on the construction progress stage, and a reference value can be set for the cost input of the construction process, providing an effective reference for workers and managers, reducing the workload of managers, and improving the work efficiency of workers.

[0108] Example 4

[0109] Based on Example 1, the method for fully intelligently analyzing the deviation between project investment and schedule, step 3, includes:

[0110] Step 31: Acquire the progress data of the current engineering project, establish a real-time project progress of the current engineering project based on the progress data, divide the real-time project progress into stages according to the construction progress phases, and determine the current construction progress of the current engineering project;

[0111] Step 32: Establish a planned construction time period corresponding to each construction progress stage according to the construction contract, determine the actual construction time period corresponding to the current construction progress according to the progress data, and establish a positive progress performance index for the current construction progress when the actual construction time period is ahead of the planned construction time period; otherwise, establish a negative progress performance index;

[0112] Step 33: Counting the progress performance index corresponding to each completed construction progress, creating a comprehensive progress performance chart for the current construction progress, and using the comprehensive progress performance chart to perform cost accounting on the current construction progress to obtain the actual cost amount of the current construction progress;

[0113] Step 34: Allocate the actual cost amount to each of the constructed progress to obtain the cost amount corresponding to each of the constructed progress, establish a budget item corresponding to each of the constructed progress, correct the budget amount of the corresponding budget item according to the construction amount of the current progress corresponding to the current construction progress, and generate a valid budget item for the current construction progress.

[0114] In this example, process data refers to the data generated when executing this engineering project;

[0115] In this example, the positive progress performance index represents the performance index generated when the current construction progress is faster than the planned progress, and the negative progress performance index represents the performance index generated when the current construction progress is slower than the planned progress;

[0116] In this example, each completed progress corresponds to a progress performance index;

[0117] In this example, the amount attributed to the cost indicates the amount of cost allocated to the construction progress. This is done to achieve more detailed cost allocation and to decompose cost items with multiple list items.

[0118] The working principle and beneficial effects of the above technical solution: In order to further improve the effectiveness of intelligent analysis, in the actual work process, the process data generated by this project is collected in real time, so as to establish the real-time project process of this project, and the current construction progress of this project is determined by a phased processing method. The cost accounting of the constructed progress is carried out by analyzing the performance index of the current construction progress, and the actual cost amount of the current construction progress is determined. Then, the cost amount of the constructed progress is determined by amount allocation, and a budget item of each constructed progress is established. In this way, the construction cost can be monitored in real time, and the construction situation corresponding to each expenditure can be clarified, thereby establishing a budget item, which serves as a basis for the subsequent analysis of the deviation between cost and progress.

[0119] Example 5

[0120] Based on Example 4, the method for fully intelligently analyzing project investment and schedule deviations includes:

[0121] When the construction volume of the current progress corresponding to the current construction progress is not 100%, the estimated volume of the corresponding estimated item is proportionally compressed according to the construction volume of the current progress to generate a valid estimated item corresponding to the current construction progress;

[0122] When the construction volume of the current progress corresponding to the current construction progress is 100%, the estimated budget item corresponding to the current construction progress is regarded as a valid estimated budget item.

[0123] Example 6

[0124] Based on Example 4, the method for fully intelligently analyzing project investment and schedule deviations includes:

[0125] Obtaining a historical progress performance index corresponding to an adjacent construction progress before the current construction progress, and establishing a performance vector of the adjacent construction progress;

[0126] When the actual construction time period is ahead of the planned construction time period, establishing a time difference vector between the actual construction time period and the planned construction time period, and calculating an inner product between the time difference vector and the performance vector;

[0127] Adding a positive sign to the calculation result to generate a positive progress performance index of the current construction progress;

[0128] When the actual construction time period lags behind the planned construction time period, obtaining the lag time of the current construction progress, and analyzing the construction position corresponding to the lag time within the actual construction time period;

[0129] Obtain the ratio of the actual construction duration to the planned construction duration corresponding to the construction location, add a positioning symbol to the ratio of the actual construction duration to the planned construction duration according to the construction code of the construction location, and add a reverse symbol to the ratio of the actual construction duration to the planned construction duration to generate a reverse progress performance index of the current construction progress.

[0130] In this example, the time difference vector indicates the direction from the actual construction period to the planned construction period, and the modulus is the time difference between the actual construction period and the planned construction period.

[0131] In this example, the construction code represents the project code corresponding to a construction location, and different construction locations correspond to different construction codes.

[0132] The working principle and beneficial effects of the above technical solution are as follows: by processing the current construction progress in different situations, different progress performance indexes are established for the current construction progress in different situations, thereby providing a powerful accounting standard for cost accounting work.

[0133] Example 7

[0134] Based on Example 1, the method for fully intelligently analyzing project investment and progress deviations, step 4, includes:

[0135] Step 41: Counting several budget items of the current engineering project, establishing a dynamic structure of the current engineering project based on the budget content corresponding to each budget item, identifying the budget cost corresponding to each budget item in the dynamic structure, analyzing the deviation value corresponding to each budget item based on the planned cost amount corresponding to each construction stage, and determining the current cost deviation amount of the current engineering project;

[0136] Step 42: Determine the remaining cost amount corresponding to the current project based on the current cost deviation amount, and reallocate the remaining cost amount according to the amount ratio corresponding to each of the unfinished construction progress stages to obtain the allocated cost amount corresponding to each of the unfinished construction progress stages;

[0137] Step 43: Analyze the execution standards of the cost items corresponding to each of the unfinished construction progress stages, determine the validity of the corresponding allocated cost amounts based on the execution standards, make small adjustments to the allocated cost amounts based on the validity corresponding to each of the unfinished construction progress stages, and obtain the effective cost amounts corresponding to each of the unfinished construction progress stages.

[0138] In this example, the dynamic structure represents the capital flow structure of this project;

[0139] In this example, the estimated cost represents the sum of all construction costs in a construction schedule;

[0140] In this example, a small adjustment means an amount within 5% of the allocated amount.

[0141] The working principle and beneficial effects of the above technical solution are as follows: by analyzing the estimated items of this project to establish the dynamic structure of this project, then identifying the estimated cost of each estimated item, determining the current cost deviation of this project, and then reallocating the remaining cost amount of this project. In order to ensure the rationality of the amount allocation, the allocated cost amount is slightly adjusted according to the execution standard of each cost item, and the effective cost amount corresponding to each unfinished construction progress stage is determined. In this way, the cost investment can be adjusted according to the actual situation during the actual construction process, which can not only ensure the smooth progress of the construction process, but also ensure the openness and transparency of the invested funds and control the investment risks.

[0142] Example 8

[0143] Based on Example 7, the method for fully intelligently analyzing project investment and schedule deviations further includes:

[0144] When the current cost deviation is higher than the specified deviation value, it is determined that the completed construction progress of the project is abnormal;

[0145] Tracing the source of the project amount included in each of the budget items to obtain the project purpose corresponding to each of the project amounts;

[0146] Determine unusual project uses based on the valid cost range corresponding to each of the stated project uses;

[0147] Locate the use of the abnormal project, generate an abnormal report for the current project and display it.

[0148] In this example, the specified deviation value represents 7% of the current cost deviation amount.

[0149] The working principle and beneficial effects of the above technical solution are as follows: when the cost of the completed construction progress is too high or too low, it indicates that there is an abnormality in the project that has been completed at this time. Then, the source of each project amount is traced to determine the purpose of the abnormal project expenditure, and the report is provided for management personnel to review, which helps management personnel to discover and solve problems in a timely manner.

[0153] A cost allocation module is used to match each cost item with a corresponding checklist item, and to establish a planned cost amount corresponding to each construction progress stage of the project according to the project task corresponding to each checklist item;

[0154] A budget verification module is used to determine the actual cost amount corresponding to the current construction progress based on the current construction progress and the progress performance index of the current project, and generate budget items corresponding to the current construction progress;

[0155] The intelligent adjustment module is used to analyze the current cost deviation of the current engineering project based on several estimated items of the current engineering project, and to adjust the cost of each unfinished construction progress stage.

[0156] In this example, PBS decomposition represents the process of breaking down a construction contract into projects, and WBS decomposition represents the process of breaking down a construction contract into work tasks.

[0157] In this example, the cost item represents the capital expenditure of this project;

[0158] In this example, the checklist items represent the activities that need to be performed to complete this engineering project;

[0159] In this example, a cost item can match one or more list items;

[0160] In this instance, a project task represents the execution task targeted by a checklist item;

[0161] In this example, the progress performance index represents the performance of the current construction progress and the performance value corresponding to the performance;

[0162] In this example, the actual cost amount represents the cost consumed to complete the current construction progress;

[0163] In this instance, cost adjustment represents the process of reallocating the remaining cost budget;

[0164] In this example, the budget item represents the cost plan for the current construction progress.

[0165] The working principle and beneficial effects of the above technical solution are as follows: In order to uniformly quantify investment data and progress and resolve the issue of progress data and investment data belonging to two different dimensions, the cost items and checklist items of the construction project are determined by decomposing the construction contract. This implements the project PBS as the basic unit, using contract settlement data as the actual project costs, and allocating them to each project PBS based on the cost baseline. Then, based on the matching relationship between cost items and checklist items, the planned cost amount corresponding to each construction progress stage of the project is estimated. During actual construction, the actual cost amount of the current construction progress is determined based on the current construction progress and the progress performance index, thereby establishing an estimated cost item for the current construction progress. By uniformly analyzing the estimated cost items, the current cost deviation amount is obtained, and finally, the remaining cost amount is reallocated. This not only solves the problem of inconsistent comparison bases in traditional technologies, but also enables accurate comparative analysis and accurately locates links with large deviations, promotes the refined management of investment and progress of construction projects, and can also reallocate limited cost amounts according to actual circumstances, improving the clarity of capital investment and avoiding unidentified expenditures.

[0166] Example 10

[0167] Based on Example 9, the system for fully intelligently analyzing project investment and schedule deviations, wherein the budget verification module includes:

[0168] a first checking unit configured to obtain progress data of the current engineering project, establish a real-time project progress of the current engineering project based on the progress data, divide the real-time project progress into stages according to the construction progress phases, and determine a current construction progress of the current engineering project;

[0169] a second checking unit for establishing a planned construction time period corresponding to each construction progress stage according to the construction contract, determining an actual construction time period corresponding to the current construction progress according to the progress data, and establishing a positive progress performance index for the current construction progress when the actual construction time period is ahead of the planned construction time period, and establishing a negative progress performance index otherwise;

[0170] a third checking unit, configured to calculate a progress performance index corresponding to each completed construction progress, establish a comprehensive progress performance chart of the current construction progress, and perform cost accounting on the current construction progress using the comprehensive progress performance chart to obtain an actual cost amount of the current construction progress;

[0171] The fourth verification unit is used to allocate the actual cost amount to each of the constructed progress, obtain the cost amount corresponding to each of the constructed progress, establish a budget item corresponding to each of the constructed progress, correct the budget amount of the corresponding budget item according to the construction amount of the current progress corresponding to the current construction progress, and generate a valid budget item for the current construction progress.

[0172] In this example, process data refers to the data generated when executing this engineering project;

[0173] In this example, the positive progress performance index represents the performance index generated when the current construction progress is faster than the planned progress, and the negative progress performance index represents the performance index generated when the current construction progress is slower than the planned progress;

[0174] In this example, each completed progress corresponds to a progress performance index;

[0175] In this example, the amount attributed to the cost indicates the amount of cost allocated to the construction progress. This is done to achieve more detailed cost allocation and to decompose cost items with multiple list items.

[0176] The working principle and beneficial effects of the above technical solution: In order to further improve the effectiveness of intelligent analysis, in the actual work process, the process data generated by this project is collected in real time, so as to establish the real-time project process of this project, and the current construction progress of this project is determined by a phased processing method. The cost accounting of the constructed progress is carried out by analyzing the performance index of the current construction progress, and the actual cost amount of the current construction progress is determined. Then, the cost amount of the constructed progress is determined by amount allocation, and a budget item of each constructed progress is established. In this way, the construction cost can be monitored in real time, and the construction situation corresponding to each expenditure can be clarified, thereby establishing a budget item, which serves as a basis for the subsequent analysis of the deviation between cost and progress.
