承包商視角下的改進(jìn)掙得值法研究
[Abstract]:In the engineering construction industry is still in the rapid development of contemporary, contractors as a major part of the implementation of the project, in which plays a pivotal role. As one of the three major parts of project management, cost is also the content that project managers should focus on and control management. Contractor's cost control is the core to measure the success of the project and the efficiency of the enterprise. It is very important for the analysis and evaluation of the engineering construction project and related enterprises: as a traditional cost analysis method, the earned value method is still of practical value. Plays an important role in helping to analyze costs and progress. However, when the contractor uses it, its pertinence is not strong. In the face of the current situation, the thesis has done the following main work: analyze the essence of earned value method, find its unreasonable place, and carry on the improvement from the contractor's point of view, This paper introduces new indexes PVc and EVc, to get new analysis indexes and distinguishes some former indexes. On the premise of assuming contractor's planned profit the analysis results are summed up and summarized completely. The GA-SVM estimation model is established to determine the value of PVc. The support vector machine estimation model is introduced, the characteristics of the method and the problems to be solved are summarized, the genetic algorithm is briefly described, and the GA-SVM estimation model is constructed. This paper explains the process of using the model to estimate and the important content involved in it; summarizes the process of cost analysis based on the GA-SVM estimation model and the improved earned value; and explains the application of the improved earned value method to the multi-time point analysis. Case N is introduced to collect similar projects in this area using GA-SVM model to carry out regression analysis and predict their PVc value, and cost analysis is carried out from the contractor's point of view, and by comparing the monitoring data of different time nodes, the management effect during the period is evaluated. Compared with the traditional method, the advantages of the improved method are summarized. By improving the traditional earned value method, it can be fully applied by the contractor and can better reflect the complex situation of project schedule and cost. At the same time, the introduction of scientific estimation methods and the application of computer technology to change the inefficient state of project management is a preliminary exploration for the scientific implementation of engineering project management, which is of certain practical significance.
