AbstractThe author presents a new comprehensive evaluation method based on uncertainty theory in this paper. According to this kind of method, the evaluation quality of each evaluated index given by every expert is regarded as an uncertain variable. Then a comparison rule of uncertain comprehensive evaluation is proposed by means of expected value of uncertain variable. Some properties about the comparison rule are discussed. At last, an example about the comparison of urban environment quality is given to illustrate the uncertain comprehensive evaluation method.

Core Rockfill Dam

Construction progress and quality are two important objectives in the construction of high core rockfill dam. It is of great significance to evaluate their control effect comprehensively. In this paper, the progress and quality of high core rockfill dam construction management are the study objectives. in order to achieve the real-time control of coupling them, the comprehensive evaluation method for the quantitative analysis of their complex relationship is proposed. Based on the comprehensive analysis of the mechanisms of the influence related factors in the construction process, the comprehensive evaluation index system of the high core rockfill dam coupling construction progress and quality is designed ; the comprehensive evaluation index data acquisition process is analyzed; the comprehensive evaluation method for the high core rockfill dam filling unit is put forward. finally, a comprehensive evaluation of high core rockfill dam filling unit model based on TOPSIS is established. Engineering examples show that this method plays a guiding role in real-time control of coupling high core rockfill dam construction progress and quality.

Rational Evaluation

Evaluation of teachers is one of the most important sectors for colleges and universities to foster a high-quality teaching staff influencing the training qualities of students directly. Scientific and rational evaluation of teachers has the important guide functions to improve the quality of teachers, inspire teachers' potential and creativity and encourage teachers to make constant progress. It is difficult to evaluate one teacher objectively and fairly using the ordinary evaluation method for the influencing factors are more and complex. The fuzzy comprehensive evaluation method of selecting outstanding teachers in university is proposed in this paper, its main goal is to make the scientific and rational evaluation on one teacher and select outstanding teachers. Finally, an example of fuzzy comprehensive evaluation on one certain teacher for the illustration of the proposed method is represented, the result indicates that the scientific and rational evaluate result is provided by the fuzzy comprehensive evaluation method.

Bid Price

There are two kinds of bid evaluation methods in China, which are the lowest bid price method and the comprehensive evaluation method. They have their own advantages and disadvantages, and they can’t replace each other. Especially, the applicable scope of comprehensive evaluation method is wide. Quantifying the technical bid and commercial bid weighted, calculating for each bid comprehensive evaluating price or comprehensive evaluation points, and then selecting a high comprehensive quality unit. The paper aims at the particularity of comprehensive evaluation method. Then to study the content of the construction quality management system, the indicators and criteria, which guarantees the quality of the project.

Self-compacting concrete (SCC) has been widely used in engineering for improving the product quality and efficiency at the construction sites, enhancing the working conditions and the appearance of concrete. Workability is an important property of SCC. But none of a single method has been developed for evaluation workability of SCC efficiently. Aiming at the quality control of fresh SCC, a fuzzy comprehensive evaluation method for evaluating workability of SCC was put forward and a case study was done by measuring slump, slump flow, L-box ratio, J-ring flow, bleeding and sieve segregation of fresh SCC in the present paper. Evaluation results indicated that fuzzy comprehensive evaluation method can give a quantitative evaluation of workability of SCC and it is convenient to establish an expert system for controlling the quality of fresh SCC by using fuzzy comprehensive evaluation method.

Establish a nonlinear membership function of slope stability taking the case of six different sliding blocks on a typical slope and do a second class fuzzy comprehensive evaluation on the determinate membership. Comparing the result of stability evaluated with former result determined by extension classified method, it shows that it is basically conforming to evaluate slope stability using membership function which is established according to the changing rules of impact factors of slope such as quality of rock, massiveness of rock mass and dip angle of rock. This method can be referential in a qualified sense for the forecasting and preventing of landslide disasters.
