Research On Quality Cost Prediction And Management Scheme Decision Of Construction Enterprise

The paper introduces the conception and consistence of quality cost, analyses the quality cost constituents of the construction business according to the characteristics of construction enterprises, and puts forward the management system of quality cost. The paper does further study on prediction, one step in the quality cost management system. The paper makes use of linear regressive model, grey prediction model and combined forecasting methods to predict the quality cost of engineering project, analyses the superiority and inferiority of every method. Due to the theoretical defect of grey prediction formula, the paper modifies the previous formula, proposes new formula, and improves the prediction accuracy at a certain degree .In addition, the paper introduces the other five steps in the quality cost management system and management scheme decision-making method that considers value deviation. In the end, the paper uses practical data of some company to analyze the several methods introduced before.The main work of the paper is:1.to illustrate the conception of quality cost and research achievement both abroad and at home, to draw up control system according to the particular condition of the construction enterprise.2.to establish quality cost management system, to introduce the six steps of quality cost management briefly, and to analyze the correlation and interaction of every step.3.to study the prediction methods of quality cost, to establish prediction model, to analyze the superiority, inferiority, and adaptability of every method.4.to discuss the methods of and application to the quality cost management scheme decision.
