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 deviation. Background Art

[0002] In engineering construction, investment and progress are two very important factors that have a vital impact on the success of the project. The actual progress and investment completion of the engineering construction project are summarized by the completion of various work tasks and the settlement of each subcontract, which belong to two different dimensions. The completion status can only be roughly estimated based on the image progress of the construction project and the investment settlement status for rough comparison. There is no direct and accurate comparison condition, and in the event of deviation, it is impossible to intuitively analyze the specific links where the deviation occurs, making it difficult to achieve precise control and not conducive to the refined management and control of the project. In actual operation, it is often impossible to accurately compare the actual progress of the project with the completion of the investment, resulting in the inability to detect and correct the deviation of investment and progress in time, thus causing project funding risks. 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 intelligently analyzing investment and schedule deviations of engineering projects. Summary of the invention

[0066] The preferred embodiments of the present invention are described below in conjunction with 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 As shown, including:

[0069] Step 1: Perform PBS decomposition on the construction contract to obtain several cost items of the project, and perform WBS decomposition on the construction contract to obtain several list items of the project;

[0070] Step 2: Match the corresponding checklist items for each of the cost items, and establish the planned cost amount corresponding to each construction progress stage of the project according to the project tasks corresponding to each of the checklist items;

[0071] Step 3: Determine the actual cost amount corresponding to the current construction progress according to the current construction progress and progress performance index of the project, and generate the budget item 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 decomposing a construction contract into projects, and WBS decomposition represents the process of decomposing a construction contract into work tasks;

[0074] In this example, the cost item represents the capital expenditure of this engineering 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 inventory items;

[0077] In this example, a project task represents an execution task that a checklist item targets;

[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 quantify the investment data and progress uniformly and solve the problem that the progress data and investment data belong to two different dimensions, the cost items and list items of this construction project are determined by decomposing the construction contract, and the project PBS is used as the basic unit. The contract settlement data is used as the actual cost of the project, and the cost baseline is used as the link to allocate it to each PBS of the project. Then, according to the matching relationship between the cost item and the list item, the planned cost amount corresponding to each construction progress stage of this engineering project is estimated. Therefore, in actual construction, the actual cost amount of the current construction progress is determined according to the current construction progress and the progress performance index, so as to build the budget item of the current construction progress, and the current cost deviation amount is obtained by uniformly analyzing the budget items. Finally, the remaining cost amount is reallocated. In this way, the problem of inconsistent comparison basis in traditional technology can be solved, and accurate comparative analysis can be achieved, and the links with large deviations can be accurately located, which can promote the investment and progress of engineering construction projects. Refined management, limited cost amount can also be reallocated according to actual conditions, which improves the clarity of capital investment and avoids expenditures with unknown flows.

[0083] Example 2

[0084] Based on Example 1, the method for fully intelligently analyzing the deviation between investment and schedule of an engineering project, step 1, comprises:

[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 according to the project construction contract, and determine the construction cost corresponding to each construction item according to the project cost composition;

[0086] Step 12: Establish several cost expenditures corresponding to the current engineering project according to the project cost composition, determine several expenditures corresponding to each construction project of the current engineering project in combination with the construction cost corresponding to each construction project, and generate several cost items of 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 a number of independent tasks corresponding to each of the construction projects, and generate a number of checklist items for this 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 example, 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] On the basis of Example 1, the method for fully intelligently analyzing the deviation between investment and schedule of an engineering project, the step 2 comprises:

[0094] Step 21: Create a list measurement rule for the project according to the construction drawings of the project, and use the measurement rule to measure and decompose each list item to obtain several list measurement units and corresponding list measurement methods corresponding to each list item;

[0095] Step 22: respectively identifying the cost measurement unit and the corresponding cost measurement method corresponding to each of the cost items, performing a first match between the list measurement unit and the cost measurement unit to obtain a number of adaptation cost items corresponding to each of the list items, performing a second match between the adaptation cost measurement method corresponding to the adaptation cost item and the corresponding list measurement method to obtain a number of list items corresponding to each of the cost items, and constructing a cost-list combination;

[0096] Step 23: Identify the drawing content corresponding to each of the checklist items in the construction drawing, semantically reorganize the drawing content, generate the project task corresponding to each of the checklist items, mark each of the project tasks 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 according to 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 according to 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 types of 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 net, 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 the cost item and the list item, and obtain several adaptation cost items that may match a list 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 example, the project task represents the execution task corresponding to the checklist item;

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

[0106] In this example, the mission critical node represents a mission 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 are as follows: In order to better match the cost items with the list items and avoid the phenomenon of 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 to determine the list measurement method and list dosage unit corresponding to each list item. Then, the cost items and the 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, and an accurate match is achieved to 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 engineering project, and then each cost-list combination is used to determine the cost information of each construction progress stage. Finally, the cost amount allocation is achieved, 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 investment and schedule of engineering projects, step 3, comprises:

[0110] Step 31: Acquire the progress data of the current engineering project, establish the real-time project progress of the current engineering project according to the progress data, divide the real-time project progress into stages according to the construction progress stages, 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 process data, and establish a positive progress performance index of 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: Count the progress performance index corresponding to each completed construction progress, establish a comprehensive progress performance chart of the current construction progress, and use 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, the process data represents 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 progress of this project, and the current construction progress of this project is determined by a phased processing method. The cost of the constructed progress is calculated 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 the deviation between investment and schedule of an engineering project 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 budget item corresponding to the current construction progress is regarded as a valid budget item.

[0123] Example 6

[0124] Based on Example 4, the method for fully intelligently analyzing the deviation between investment and schedule of an engineering project 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, a time difference vector between the actual construction time period and the planned construction time period is established, and an inner product between the time difference vector and the performance vector is calculated;

[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, so as to generate a reverse progress performance index of the current construction progress.

[0130] In this example, the time difference vector indicates the direction: the actual construction time period points to the planned construction time period, and the modulus is the vector of the time difference between the actual construction time period and the planned construction time period;

[0131] In this example, the construction code represents a 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] On the basis of Example 1, the method for fully intelligently analyzing the deviation between the investment and schedule of an engineering project, the step 4 comprises:

[0135] Step 41: Count several budget items of the current engineering project, establish a dynamic structure of the current engineering project according to the budget content corresponding to each budget item, identify the budget cost corresponding to each budget item in the dynamic structure, analyze the deviation value corresponding to each budget item according to the planned cost amount corresponding to each construction stage, and determine 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 effectiveness of the corresponding allocated cost amounts based on the execution standards, make small adjustments to the allocated cost amounts based on the effectiveness 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: the dynamic structure of this project is established by analyzing the estimated items of this project, and then the estimated cost of each estimated item is identified to determine the current cost deviation of this project, and then the remaining cost amount of this project is reallocated. 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 the deviation between investment and schedule of a construction project further includes:

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

[0145] Tracing the source of the project amount contained in each budget item to obtain the project purpose corresponding to each project amount;

[0146] Determine the abnormal project usage according to the effective cost range corresponding to each of the said project usages;

[0147] Locate the purpose of the abnormal project, generate an abnormal report for the 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: When the cost of the completed construction progress is too high or too low, it indicates that there is an abnormality in the engineering project that has been completed at this time, and 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.

[0152] The project decomposition module is used to perform PBS decomposition on the construction contract to obtain several cost items of the current engineering project, and perform WBS decomposition on the construction contract to obtain several list items of the current engineering project;

[0153] A cost allocation module is used to match the corresponding checklist item to each cost item, and to establish the 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 checking module is used to determine the actual cost amount corresponding to the current construction progress according to the current construction progress and progress performance index of the current engineering 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 budget items of the current engineering project, and to make cost adjustments for each unfinished construction progress stage.

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

[0157] In this example, the cost item represents the capital expenditure of this engineering 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 inventory items;

[0160] In this example, a project task represents an execution task that a checklist item targets;

[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 quantify the investment data and progress uniformly and solve the problem that the progress data and investment data belong to two different dimensions, the cost items and list items of this construction project are determined by decomposing the construction contract, and the project PBS is used as the basic unit. The contract settlement data is used as the actual cost of the project, and the cost baseline is used as the link to allocate it to each PBS of the project. Then, according to the matching relationship between the cost item and the list item, the planned cost amount corresponding to each construction progress stage of this engineering project is estimated. Therefore, in actual construction, the actual cost amount of the current construction progress is determined according to the current construction progress and the progress performance index, so as to build the budget item of the current construction progress, and the current cost deviation amount is obtained by uniformly analyzing the budget items. Finally, the remaining cost amount is reallocated. In this way, the problem of inconsistent comparison basis in traditional technology can be solved, and accurate comparative analysis can be achieved, and the links with large deviations can be accurately located, which can promote the investment and progress of engineering construction projects. Refined management, limited cost amount can also be reallocated according to actual conditions, which improves the clarity of capital investment and avoids expenditures with unknown flows.

[0166] Example 10

[0167] On the basis of Example 9, the system for fully intelligently analyzing the investment and progress deviation of engineering projects, the budget checking module includes:

[0168] A first checking unit is used to obtain the progress data of the current engineering project, establish the real-time project progress of the current engineering project according to the progress data, divide the real-time project progress into stages according to the construction progress stages, and determine the current construction progress of the current engineering project;

[0169] A second checking unit is used to 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 process data, and establish a positive progress performance index of 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;

[0170] The third checking unit is used to count the progress performance index corresponding to each completed construction progress, establish a comprehensive progress performance chart of the current construction progress, and use 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;

[0171] The fourth checking 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 the 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 the effective budget item of the current construction progress.

[0172] In this example, the process data represents 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 progress of this project, and the current construction progress of this project is determined by a phased processing method. The cost of the constructed progress is calculated 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.
