Description

Technical Field

[0001] The present invention belongs to the field of project cost, and relates to data analysis technology. Specifically, it is a whole-process dynamic management control system, method and storage medium for project cost. Background Art

[0002] Project cost management refers to the whole-process and all-round business behaviors and organizational activities that comply with policies and objective laws for the construction project cost and the price of construction and installation projects by using scientific, technical principles and methods under the principle of unified goals and each taking its own responsibility to ensure the economic benefits of the construction project and the economic rights and interests of all parties concerned.

[0003] The invention patent with the publication number of CN117829864A discloses an automatic calculation method and system for project cost materials. The automatic calculation method realizes automatic and intelligent calculation, improving the efficiency and accuracy of project cost management. However, this automatic calculation method cannot analyze the accuracy and reliability of channel information. When the market price fluctuates greatly but the channel information is not updated in time, it will lead to a decrease in the accuracy of the calculation result and finally give a calculation result that does not conform to the actual situation.

[0004] In view of the above technical problems, the present application proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide a whole-process dynamic management control system, method and storage medium for project cost, which is used to solve the problem that the prior art cannot analyze the accuracy and reliability of channel information;

[0006] The technical problem to be solved by the present invention is: how to provide a whole-process dynamic management control system, method and storage medium for project cost that can analyze the accuracy and reliability of channel information.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A whole-process dynamic management control system for project cost includes a management control platform, and the management control platform is communicatively connected with a list verification module, a reliability analysis module, a risk control module and a data storage module;

[0009] The list verification module is used to verify and analyze the project cost list: generate a verification period and divide the verification period into several verification time periods. At the end of each verification time period, randomly distribute the project cost list to each network server according to the project name. After receiving the project cost list, the network server marks the project cost list as the verification object, verifies and analyzes the verification object to obtain the cost deviation data ZP and the quotation deviation data BP; perform numerical calculations on the cost deviation data ZP and the quotation deviation data BP to obtain the deviation coefficient PC of the verification object, and determine whether the accuracy of the verification object meets the requirements through the deviation coefficient PC;

[0010] The reliability analysis module is used to perform reliability analysis on the verification and analysis results of the project cost list: when the completion quantity of the verification time period reaches L1, at the end of the subsequent verification time period, mark the completion quantity of the verification time period as the completion value, mark the number of times the network server is marked as the correction object as the correction value, mark the ratio of the correction value to the completion value as the correction coefficient, and determine whether the data reliability of the network server meets the requirements through the correction coefficient;

[0011] The risk control module is used to perform audit risk control analysis on the project cost list.

[0012] Further, the process of obtaining the cost deviation data ZP includes: obtaining the project unit price and project quantity of each item in the verification object, marking the product of the project unit price and the project quantity as the single item amount of the project, summing up the single item amounts of all projects to obtain the verification amount, obtaining the total cost value output by the verification object and marking it as the cost amount, marking the absolute value of the difference between the verification amount and the cost amount as the cost deviation amount, and marking the ratio of the cost deviation amount to the verification amount as the cost deviation data ZP.

[0013] Further, the process of obtaining the quotation deviation data BP includes: the network server retrieves the market quotation range corresponding to the project from the database, marks the average value of the maximum value and the minimum value of the market quotation range as the market quotation standard value, marks the absolute value of the difference between the project unit price and the market quotation standard value as the quotation deviation amount, marks the ratio of the quotation deviation amount to the market quotation standard value as the quotation deviation value of the project, and sums up and averages the quotation deviation values of all projects in the verification object to obtain the quotation deviation data BP.

[0014] Further, the specific process for determining whether the accuracy of the verification object meets the requirements includes: obtaining the deviation threshold PCmax through the data storage module, and comparing the deviation coefficient PC of the verification object during the verification period with the deviation threshold PCmax. If the deviation coefficient PC is less than the deviation threshold PCmax, it is determined that the accuracy of the verification object meets the requirements, and both the verification object and the corresponding network server are marked as normal objects. If the deviation coefficient PC is greater than or equal to the deviation threshold PCmax, it is determined that the accuracy of the verification object does not meet the requirements, and both the verification object and the corresponding network server are marked as correction objects. Meanwhile, a correction signal is generated and sent to the mobile terminal of the management staff through the management control platform.

[0015] Further, the specific process for determining whether the data reliability of the network server meets the requirements includes: obtaining the correction threshold through the data storage module, and comparing the correction coefficient with the correction threshold. If the correction coefficient is less than the correction threshold, it is determined that the data reliability of the network server meets the requirements. If the correction coefficient is greater than or equal to the correction threshold, it is determined that the data reliability of the network server does not meet the requirements, and the corresponding network server is marked as an update server. A data update signal is generated and sent to the mobile terminal of the management staff of the update server through the management control platform.

[0016] Further, the specific process for the risk control module to conduct an audit risk control analysis on the project cost list includes: at the end of the verification period, marking the number of times the verification object is marked as a correction object as the risk value, marking the ratio of the risk value to the completion value as the risk coefficient, obtaining the risk threshold through the data storage module, and comparing the risk coefficient with the risk threshold. If the risk coefficient is greater than or equal to the risk threshold, it is determined that the verification object has an audit risk, and a risk warning signal is generated and sent to the mobile terminal of the management staff through the management control platform. If the risk coefficient is less than the risk threshold, a continuous risk analysis is performed on the verification object.

[0017] Further, the specific process for conducting a continuous risk analysis on the verification object includes: marking the difference between the deviation coefficient PC of the verification object in the current verification period and the deviation coefficient PC in the previous verification period as the continuous value, obtaining the continuous threshold through the data storage module, and comparing the continuous value with the continuous threshold. If the continuous value is less than the continuous threshold, it is determined that the verification object does not have an audit risk. If the continuous value is greater than the continuous threshold, it is determined whether the network server used in the current verification period is marked as an update server. If so, the verification object is assigned to another network server to re-perform the verification analysis, risk control analysis, and continuous risk analysis. If not, it is determined that the verification object has an audit risk, and a risk warning signal is generated and sent to the mobile terminal of the management staff through the management control platform.

[0018] A method for dynamic management and control of the whole process of project cost, comprising the following steps:

[0019] Step 1: Check and analyze the project cost list and mark the check object as a normal object or a correction object;

[0020] Step 2: Analyze the reliability of the check and analysis results of the project cost list and determine the data reliability of the network server;

[0021] Step 3: Analyze the audit risk control of the project cost list and determine whether the check object has audit risk.

[0022] A computer storage medium, on which a computer program is stored, and when the program is executed by a processor, it implements the method for dynamic management and control of the whole process of project cost.

[0023] The present invention has the following beneficial effects:

[0024] 1. Through the list check module, the project cost list can be checked and analyzed, the deviation analysis of the project cost list can be carried out from the perspective of the list cost and the market quotation, and the deviation coefficient can be obtained. The deviation coefficient is used to feedback the deviation degree of the result of the project cost list. At the same time, the check results are updated regularly in the way of periodic time-sharing check, and the project cost list is randomly assigned to each network server for check operation according to the project name, so as to reduce the loss risk brought by the check of a single network server and help to improve the data security;

[0025] 2. Through the reliability analysis module, the reliability of the check and analysis results of the project cost list can be analyzed. Based on the premise of randomly assigning check tasks, the number of times the network server is marked as a correction object is counted and the correction coefficient is obtained. According to the correction coefficient, the necessity of data update of a single network server is feedback, so as to ensure the accuracy of the check results;

[0026] 3. Through the risk control module, the audit risk control analysis of the project cost list can be carried out, the marking results of the check object in all check time periods are counted and the risk coefficient is obtained. According to the risk coefficient, the audit risk degree of the check object is feedback, and the check object with audit risk is marked and warned in combination with continuous risk analysis.
