Abstract

This article is based on the Ministry of Construction Standard Quota \The project cost index for construction-related units have very important significance. In the feasibility study stage, the project cost index to provide a basis for determining the investment estimation, is the main basis of the owners to make decisions; design phase, the project cost index can be used to calculate the budget for the cost limit design and reasonable choice design provides a reliable reference cost limit; bidding stage, the use of the tender side project cost index can be determined reasonable in price, to avoid the phenomenon appears below the cost price bid; construction phase, the project cost index provides an important reference for the preparation of the budget cost of the budget cost accuracy can be quick to judge. The papers selected the largest urban construction project in the amount of residential construction projects, project cost index as an object of study. First, starting from the choice of the exponential model, the analysis and comparison of eight exponential model, the final selection of the Laspeyres and Paasche index model as a research tool, and gives the formula of the project cost index model; followed on composite index weights determine a combination of qualitative and quantitative analysis; followed by the acquisition of the project cost information gives more comprehensive recommendations; final prediction model instance forecast. The main contents include the following sections: (1) the choice of the exponential model essays on eight index model is a simple index, simple arithmetic average index, Laspeyres, Paasche index, ideal index, function index, socialist countries index covariant affect the index from the bias of the indices and the pros and cons of a comprehensive comparison to finalize the selection of the index model Laspeyres and Paasche index. ② project cost index preparation of project cost index generally divided into a single index and the composite index, the article gives a single index and the composite index formula. ③ exponential model weights determined for the preparation of the composite index, weights determine has a decisive role, but because of the differences of the construction projects, which makes the determination of the weights tend to remain in the stage is determined based on the subjective experience that is qualitatively Analysis. The paper presents a qualitative and quantitative analysis method of combining :1-9 ratio scale method, referred to as the scale method, and gives a simple example. ④ project cost information collected standard Ministry of Construction Standard Quota to strengthen the monitoring and guidance of urban residential construction costs, standardize and unify the building of the National Urban residential construction project cost information database, developed urban housing construction project cost information data standard \uniform format and content (referred to as \(5) prediction theory application eight prediction methods, a comprehensive comparison of the final selection of the ARMA model and gray prediction model to predict the application instance.
