Description
Technical Field
The invention relates to the technical field of engineering cost management, in particular to a settlement control over-approximate-calculation early warning method and system for engineering projects.
Background
The project budget is the plan for the project to generate revenue and expenditure for a given period of time in the future. The method can evaluate the investment of engineering projects in a currency form and reflect the economic effect of the engineering. The method is the basis for strengthening enterprise management, carrying out economic accounting, assessing engineering cost and compiling construction plan, and is also the main basis for bidding and quotation of engineering tenders and determining engineering cost. The project settlement refers to the final settlement of the project price to a contracting unit after a construction enterprise completes all contracted projects according to the content specified by a contract, the quality of the received projects is qualified, and the contract requirements are met. The project settlement is a summary file of all construction cost, construction achievement and financial condition from the beginning of project completion to the completion delivery of the project by taking the physical quantity and the currency index as measurement units.
The construction period of the project is long, the number of the consumed funds is large, intermediate settlement and annual settlement are needed to be carried out on the project cost for the construction and installation enterprises to compensate the funds consumed in the construction in time, and completion settlement is needed after all project completion acceptance. It can be seen that project settlement is an important task in the contract of project, and for this reason, chinese patent publication No. CN111582915A discloses "a project budget and settlement comparison system" which includes a budget input unit, a settlement input unit, a budget data storage unit, a settlement data storage unit, a calculation unit, a data comparison unit, and an input recording unit. Simultaneously, also discloses the following steps: inputting the project budget of the current month into a budget input unit; the project budget data enters the calculation unit for calculation and then is stored in the budget data storage unit; and then the project settlement data in the current month is input into a settlement input unit.
The project budget and settlement comparison system in the above-mentioned conventional scheme can conveniently compare the project settlement amount (data) with the estimated amount, and further can judge whether the amount of the project cost settlement exceeds the estimated amount (i.e. exceeds the estimated amount). However, in actual research, the applicant has found that before the construction cost is settled, the construction project is subjected to construction stages such as a new start stage, a reconstruction stage and a completion stage, and the construction stages generate corresponding cost. However, the existing scheme only manages the amount of the project cost settlement node, but does not manage the contract amount in the construction stage, so once the amount of the project cost settlement node exceeds the approximate value, the method is difficult to make up, and the existing scheme has a poor effect of the excess control of the project cost settlement node. In addition, after an engineering project is over-approximated, some enterprises need to select 'work stealing and material reduction' in the subsequent construction process to avoid continuing over-approximated calculation, so that the engineering quality is difficult to guarantee. Therefore, the applicant thinks of designing a super-approximate calculation early warning method capable of carrying out super-approximate calculation early warning on each construction stage before the settlement so as to improve the super-approximate management and control effect on the settlement of the engineering project.

Detailed Description
The following is further detailed by the specific embodiments:
the first embodiment is as follows:
the embodiment discloses a settlement control over-approximate-calculation early warning method for an engineering project.
A construction stage before an engineering project settlement stage is divided into a plurality of project nodes, contract amount of each project node is compared with a corresponding node early warning value when the project node occurs, and corresponding super-approximate-calculation early warning is sent out when the contract amount of the project node exceeds the corresponding node early warning value. As shown in fig. 1, the method specifically includes the following steps:
s1: correspondingly dividing a construction stage before an engineering project settlement stage into a plurality of project nodes; then, correspondingly generating a node early warning value of each project node and a settlement early warning value in a settlement stage according to the approximate calculation amount of the project;
s2: acquiring contract amount of the project node when the project node occurs, comparing the contract amount of the project node with a corresponding node early warning value, and sending a corresponding over-approximate-calculation early warning signal when the contract amount is larger than the corresponding node early warning value;
s3: and acquiring corresponding contract amount in a settlement stage, comparing the contract amount in the settlement stage with the corresponding settlement early warning value, and sending a corresponding super-approximate-calculation early warning signal when the contract amount is greater than the corresponding settlement early warning value.
In the invention, the construction stage before the project settlement stage is divided into a plurality of project nodes, and the contract amount of each project node is controlled, so that the project can be prevented from exceeding budget during construction, further the problem of excessive approximate calculation of the project in the settlement stage can be avoided to a certain extent, the control effect of the project settlement can be improved, and the project quality can be assisted to be improved. And secondly, the node early warning value and the settlement early warning value are generated by calculating in advance according to the approximate calculation amount and the historical data or the experience value, so that the cost control effect on each project node and the settlement stage is better, and the control effect on the project settlement can be improved.
In a specific implementation process, in step S1, a node risk value corresponding to each project node is generated according to the estimated amount of the engineering project; in step S2, when a project node occurs, the contract amount of the project node is compared with the corresponding node risk value, and a corresponding risk early warning signal is sent when the contract amount is smaller than the corresponding node risk value.
In the actual management and control process, some construction enterprises can purchase some cheap building materials with specifications inconsistent with preset rules in order to avoid over-approximate calculation, so that the quality of engineering projects is difficult to ensure. Therefore, the node risk value is set, and a corresponding risk early warning signal can be sent out when the contract amount is smaller than the corresponding node risk value, namely, a risk early warning can be sent out when the contract amount is obviously inconsistent with the budget amount so as to remind relevant personnel to check, thereby assisting in improving the engineering quality.
In a specific implementation process, as shown in fig. 2, step S3 specifically includes the following steps:
s31: after the submission information of the settlement stage passes, acquiring a first contract audit amount and a second contract audit amount of the settlement stage; the settlement early warning value is ninety percent of the approximate amount;
s32: comparing the first-order-of-contract amount with the corresponding settlement early warning value, and if the first-order-of-contract amount is greater than the settlement early warning value, sending a corresponding super-approximate-calculation early warning signal; otherwise, entering the next step;
s33: comparing the second amount of examination of the contract with the corresponding settlement early warning value, and if the second amount of examination of the contract is greater than the settlement early warning value, sending a corresponding super-approximate calculation early warning signal; otherwise, entering the next step;
s34: and entering a final stage.
In the settlement stage, the invention firstly checks the settlement submission information, controls the amount of money in the settlement stage after the submission information passes, and can send out a corresponding super-approximate calculation early warning signal, thereby improving the control effect on the engineering settlement. And secondly, the invention carries out two different risk control on the contract amount in the settlement stage, which is beneficial to improving the control effect on the project settlement.
In the specific implementation process, in step S1, the construction phase before the engineering project settlement phase is divided into new construction nodes, reconstruction nodes, continued construction nodes and completed construction nodes.
According to the method and the system, each project node is correspondingly divided according to the construction stage of the project, so that the divided project nodes can be adapted to the actual construction process of the project, the control effect on each project node can be improved, and the control effect on the project settlement can be improved.
In the specific implementation process, the node early warning value of the new start node is forty percent of the approximate calculation amount, and the node risk value of the new start node is twenty percent of the approximate calculation amount; the node early warning value of the reconstruction node and the reconstruction node is seventy percent of the approximate calculation amount, and the node risk value of the reconstruction node and the reconstruction node is fifty percent of the approximate calculation amount; the node early warning value of the completed node is eighty percent of the approximate amount, and the node risk value of the completed node is sixty percent of the approximate amount.
According to the invention, through setting the node early warning value and the node risk value of each project node, the cost control effect on each project node and the settlement stage is better, and the risk early warning can be sent out when the contract amount and the budget amount are obviously inconsistent so as to remind related personnel to check the material and cost information, so that the control effect on the project settlement can be improved, and the project quality can be assisted to be improved.
Example two:
on the basis of the first embodiment, the embodiment discloses a method for updating a node early warning value.
In step S1 of this embodiment, when the contract amount of the previous project node is smaller than the corresponding node warning value, the node warning value of the next project node is adjusted according to the contract amount of the previous project node and the corresponding node warning value.
According to the invention, the node early warning value of the next project node can be adjusted according to the difference value between the contract amount of the previous project node and the node early warning value, so that the final settlement amount of the project can be more fit with the approximate calculation amount, thus the cost of each project node can be better controlled, and the control effect of the project settlement can be favorably improved.
For example, the preset node early warning value of the new start node is forty percent of the estimated amount; the node early warning value of the reconstruction node and the reconstruction node is seventy percent of the approximate calculation amount; and the node early warning value of the completed node is eighty percent of the approximate calculation amount. Then, when the contract amount of the new start node is twenty-five percent of the estimated amount, the difference value between the contract amount of the new start node and the node early warning value is fifteen percent, so that the node early warning value of the next project node of the new start node, the rebuilt node and the rebuilt node is adjusted to seventy-five percent of the estimated amount in the embodiment. When the contract amount of the new start node is thirty-eight percent of the approximate amount, the difference value between the contract amount of the new start node and the early warning value of the node is two percent, so that the early warning values of the next project node, the reconstruction node and the reconstruction node of the new start node are adjusted to be sixty-nine percent of the approximate amount.
Specifically, when the difference value between the contract amount of the previous project node and the node early warning value is greater than ten percent, the node early warning value of the next project node is correspondingly adjusted upwards; and when the difference value between the contract amount of the previous project node and the node early warning value is less than five percent, correspondingly adjusting the node early warning value of the next project node downwards. The specific adjustment value is determined according to historical data or corresponding engineering projects. Thus, the final settlement amount of the engineering project can be more matched with the estimated amount.

the central management unit is used for inputting the contract amount of the project node into a pre-established super-probability early warning model and acquiring a super-probability early warning result output by the super-probability early warning model;
and the super-probability early warning model generates a node early warning value corresponding to the project node according to the approximate amount of money, then compares the contract amount of the project node with the corresponding node early warning value, and outputs the corresponding super-probability amount and sends out a super-probability early warning signal as a super-probability early warning result when the contract amount of money is greater than the corresponding node early warning value. In the embodiment, the super-probability early warning model is established according to each dimension parameter of the project and historical project information; each dimension parameter of the project comprises a project node, a project node start-stop time, project personnel information, project main content and project approximate calculation amount; and the super-probability early warning model calculates the corresponding node early warning value according to a Monte Carlo analysis method.
According to the invention, the construction stage before the project settlement stage is divided into a plurality of project nodes by the project stage division unit, and the contract money of each project node is controlled by combining the project node monitoring unit and the central management unit, so that the project can be prevented from exceeding budget during construction, and further the problem of overapproximate calculation of the project in the settlement stage can be avoided to a certain extent, thereby improving the control effect of the project settlement and assisting in improving the project quality. Secondly, the hyper-probabilistic early warning model generates corresponding node early warning values and settlement early warning values in advance according to the approximate calculation amount and historical data or experience values, so that the cost control effect of each project node and settlement stage is better, and the control effect of project settlement can be improved.
