Calculation And Analysis Of Engineering Cost Based On Index Model

Engineering cost index is widely used in the field of engineering construction,a way of cost accounting is the art of engineering cost and mathematical model used the combination of its reflective is the number of each product price and the change degree of project cost in time,concrete method is to use the original data,through the method of comparing machine index and index during the reporting period,each period index values,form a reflects the time sequence of number of engineering and product price system based on the analysis of the trend of the magnitude of the changes,to be able to better understand the overall situation of the construction market and the trend of supply and demand,etc.Through changing trend and the change rule of amplitude can understand cost,and these information formal owners and investors need information through the analysis of engineering cost index,winner to total cost of the whole project more fully understand,and then on the basis of economic cost analysis was carried out on the project,estimates,etc.,thus enabling project management can effectively control project,improve the management level of the project.At present,China's economic system reform into the deepening market pattern and order,further development and perfection under such a background,puts forward new requirements for engineering cost index calculation,the development of the market makes the factors affected the project cost is more complicated and diversified factors change more intense,regional differences are more obvious,which makes the engineering cost of more obvious and complex traditional static mode of accounting,engineering cost index has been unable to meet the needs of the reality of accounting,must be realistic of dynamic of construction cost accounting and management on the other hand the project cost index,the regional differences of the opposite sex is more and more obvious.It is also very difficult to carry outeffective calculation and integration.In this context,it is necessary to carry out further research on the accounting method of the total engineering cost index,so as to establish a more reasonable and scientific accounting system and method for the regional differences and realistic changes.In this paper,based on the above problems and obstacles existing in current accounting project cost expenditure of the project cost index further deep analysis and research of theoretical model,more detailed and comprehensive analysis,now widely used in various areas and calculation of all kinds of generalized index calculation model,find out the structure features of the model calculation in the process of generalization,and these models in calculating errors existing in the process of accounting,the key reference for engineering cost index has more advanced areas,such as Hong Kong,such as the UK's more mature advanced methods and experience,combined with the current our country engineering construction deficiencies and weaknesses,A set of more scientific and reasonable project cost accounting index system is established.To expect a more scientific reflect and predict the construction project cost and cost,on the basis of the new index model is established in this paper,according to different situations of construction project further calculates the total index of model analysis,specification in construction engineering the quantities bill valuation,on the basis of combining the basic principles of economics,engineering index calculation method of mathematics further generalization of the connotation of statements,understand to explain specific patterns of each model and then using the general analysis method of empirical study.The practicability and operability of the engineering cost index model and compilation method in this paper are clarified.
