Honesty is not only the cornerstone of the market economy, but also an important guarantee of maintaining market economy. Construction engineering quality inspection institutions, which are important parts of the quality supervision system, play an important role in the project management and ensuring the quality of the project. After the implementation of the "Measures for the Administration of Quality Inspection of Construction Projects", testing industry began to be operated by the market instead of government. In the face of fierce market competition and the brutal pressure to survive, many issues are prominent, just like imperfect credit system, lagging credit legal construction, lack of honest behaviors, ineffective punishment of dishonest, and so on. Again this background, there is an urgent demand that establishs a comprehensive and implemented quality inspection institutions credit rating system, which is suitable for national conditions. This paper focuses on the design and implementation of credit rating system.There are two important elements in this paper, including designing of institutions’ credit rating index system and building rating model. Firstly, it is summarized that the development of the industry and present situations of the research on the rating system. Secondly, based on literature reading and questionnaires, the factors affecting the credit is established, and then AHP and Entropy method are combined to determine the weight. Finally, a credit rating model based on SVM method is built. An example is analyzed to verify the validity and accuracy of the model, using assistant softwares of Libsvm and Matlab.A comprehensive credit rating index system and precision rating model are completed finally. The research is of great significance to provide a technical reference for the government department, credit a healthy market order, strengthen self-discipline behaviors in the market and improve the management ability of the government.
