Problems solved by technology

[0004] However, in the construction process, the actual construction cost is related to many factors, such as the price of construction materials, the increase or decrease of materials after design changes, etc. These factors are very easy to change and will greatly affect the calculation cost of the project cost. The accuracy will affect the error between the calculation cost and the actual cost in the project cost. If the error is too large, it will cause economic losses.

Embodiment 1

[0047] A method for risk management and control of the cost process, such as figure 1 shown, including the following steps:

[0048] Step S1: Obtain a plurality of historical cost data, and perform a weighted average on the multiple historical cost data to obtain an estimated cost. In step S1, the weight of the weighted average is the building volume corresponding to the historical construction cost data, wherein the building volume is the total square sum of the building or the unit square price of the building. The proportion of the weight is directly proportional to the annual growth rate of the price per unit area of ​​the building. Historical cost data can be the total construction value of completed buildings. The total number of square meters of buildings or the price per square meter of buildings can represent the value of building volume. A large total square meter of buildings represents a large building volume, and a high price per square meter of buildings represe...

Embodiment 2

[0059] A cost process risk management and control system, the difference from Embodiment 1 is that it includes a plurality of modules, and the plurality of modules are program codes running on a computer operating system such as WIN10 to implement corresponding functions, such as calling API programs, reading storage Programs for data, programs for logical operations, and programs for mathematical operations, etc., the modules are as follows:

[0060] The cost estimation module is used to obtain a plurality of historical cost data, and perform a weighted average on the multiple historical cost data to obtain a cost estimate.

[0061] Also included in the cost estimating module are:

[0062] The weight loading unit is used to load the building volume corresponding to the historical cost data into the weighted average weight, wherein the building volume is the total square sum of buildings or the square price of a building unit.

[0063] The weight matching unit is used to set ...

Abstract

The invention relates to the technical field of engineering cost, and discloses a cost process risk management and control method and system, and the method comprises the steps: S1, carrying out the weighted average of a plurality of historical cost data, and obtaining a cost estimation value; S2, carrying out unique corresponding operation on the plurality of building data sub-items and the plurality of calculation parameter items to obtain a cost summary table and a cost summary value; S3, performing unique corresponding operation on the plurality of building data sub-items and the pluralityof budget quota items to obtain a contract confirmation table and a contract confirmation value, and comparing the contract confirmation value with the cost summary value; S4, performing unique corresponding operation on the construction change item and the contract confirmation table to obtain a predicted investment table and a predicted investment value, and comparing the predicted investment value with the cost summary value; S5, performing unique corresponding operation on the plurality of updated building data sub-items and the plurality of settlement quota items to obtain a completion settlement table and a completion settlement value, and comparing the completion settlement value with the cost summary value; Risk management and control after multiple comparisons can effectively realize management and control and early warning of risks in the construction cost process.

Description

technical field [0001] The present invention relates to the technical field of engineering cost, more specifically, it relates to a risk management and control method and system for the cost process. Background technique [0002] In recent years, the rapid development of my country's economy has led to the rapid progress of the construction industry. The process of building a building is inseparable from project planning, project cost, construction and other links. Among them, project cost is an important part of construction cost control. [0003] Usually, the project cost refers to the construction price of the project, which refers to the sum of all the expected or actual costs to complete the construction of a project. From the perspective of the owner, the project cost refers to the construction cost of the project, that is, all the fixed asset investment expenses that are expected to be paid or actually paid for the construction of a project. These costs mainly includ...
