Study The Management Of Construction Projects Based On Improved Projection Pursuit Model

Construction is the backbone of basic industries matter of national economy. At thi -s stage of the construction industry in the momentum of rapid development, China is st -epping up its infrastructure, and the construction industry as an important force is drivi -ng economic development rapidly. As an important stage in the implementation of the construction industry, construction project management, which can give a direct impact on how well the development of the construction industry, played a key role. However, the ultimate goal of construction project management is to achieve the target control of the objectives. So how to achieve the control of the objectives best is an important aspe -ct of the success or failure related to the construction industry. Genetic algorithms borrow biological evolution - "survival of the fittest" rule to solve the optimization problem of the objective function significantly. The principle of projection pursuit model is exploratory data analysis methods directly from the sample data-driven. Project the high dimensional data into low dimensional space, The method that reflect the characteristics of high dimensional data by the low-dimensional projection of spatial data can be widely used in high-dimensional, non-Linear, non-normal, etc. In this paper, the projection pursuit model has to be improved, through the use of the principles twice, we can get optimal function value of the relative higher quality, and accordingly index data combination is more reasonable.The article, introducing an improved model of projection pursuit to construction pr -oject management, designed to provide more rational basis of construction project man -agement control model for the theory and the business community. Main tasks are as fo -llows.(1) Systematically introduce the concept, characteristics and significance of three o -bjectives control of the construction project management;(2)A detailed study and draw the rationality and superiority of the improved projec -tion pursuit model, and to give the specific steps of the improved projection pursuit mo -del;(3) Apply the modified projection pursuit model to the three objectives control of construction project management;(4) By case analysis, comparing with the findings of general projection pursuit mo -del to illustrate the advantages of this method.
