22 first-level construction engineer basic method for cost analysis of gold test points, first-level construction master notes, long press and like + forward + evaluation continue to be updated, click on my avatar on the Wendang version and send me private message to me: 2022
1) comparison method :
compare the actual indicators with the target indicators;
compare the actual indicators in this issue with the actual indicators in the previous issue;
compare the average level of this industry, Advanced level comparison
2) factor analysis method : also known as the chain replacement method, used to analyze the degree of impact of various factors on cost; during analysis, it is assumed that one of the many factors has changed due to
, while the other factors remain unchanged, and then replace them one by one, and compare their calculation results separately to determine the degree of impact of changes in each factor on cost;
example. The concrete cost data of a project is shown in the following table. Factor analysis method is used to analyze the degree of impact of each factor on cost.
3)Difference calculation method: The difference calculation method is a simplified form of factor analysis method. It uses the difference between the target value and the actual value of each factor to calculate its impact on cost.
4) Ratio method
is to first turn the values of the comparison and analysis into relative numbers, and then observe their relationships.
(1) correlation ratio method can compare two indicators with different properties and related properties to find the ratio, and use this to examine the quality of business results. For example: output value and wages.
(2) composition ratio method is also called gravity analysis method or structural comparison analysis method. Through the composition ratio, we can examine the composition of the total cost and the proportion of each cost item to the total cost, and we can also see the proportional relationship between budget cost, actual cost and cost reduction, so as to find ways to reduce costs.
(3) Dynamic ratio method compares the values of similar indicators in different periods and calculates the ratio to analyze the development direction and speed of this indicator. The calculation of dynamic ratios usually uses two methods: base period index and month-on-month index.
