Uncertainty theory is a branch of axiomatic mathematics dealing with experts’ belief degree. Considering the uncertainty with experts’ belief degree in the evaluation system and the different roles which different indices play in evaluating the overall goal with a hierarchical structure, a new comprehensive evaluation method is constructed based on uncertainty theory. First, index scores and weights of indices are described by uncertain variables and evaluation grades are described by uncertain sets. Second, weights of indices with respect to the overall goal are introduced. Third, a new uncertainty comprehensive evaluation method is constructed and proved to be a generalization of the weighted average method. Finally, an application is developed in evaluating software quality, which shows the effectiveness of the new method.

According to the subjectivity, randomness and fatigue of the satisfaction selection of online teaching evaluation indicators for the students, the level of teachers teaching can not truly measure by the evaluation results. This paper introduces the fuzzy comprehensive evaluation method to deal with the evaluation data, and Practice has proved that this method produced results more equitable to reflect on teaching level. Which help teachers to promptly improve and improve teaching, the variable quality of teaching time control for process control, change the static management for dynamic management.

Blast Performance

In blasting operation, some undesirable impacts, such as fly-rock, fragmentation, and back break, are induced. If the blasting design is not optimized, these mentioned impacts would reduce the blasting efficiency. To improve and optimize the blast design, blasting effect evaluation is essential. Due to the complexity of interactions among blasting parameters, empirical methods may not be appropriate for blast design optimization. A two-level mathematical model based on fuzzy mathematics, is proposed in this work. In total, 11 typical parameters were chosen and classified into three groups. The blasting effect is evaluated from three aspects, and then the comprehensive evaluation is given. A blasting effect evaluation system was developed based on the mentioned method on the platform of VC++. Some other techniques, such as image processing, were integrated into the system, which allowed for obtaining all of the parameters rapidly and conveniently. The system was applied in practical bench blast engineering. The results obtained from the system can provide effective information for the optimization of the next blast design.

The Evaluation System

In order to evaluate the application effect of spinescence as an alternative to metal segregating gratings of expressway, the evaluation system is built. By using the methods of AHP and FCE the comprehensive isolation effect evaluation of Solanum deflexicarpum is carried out. The result shows that the comprehensive evaluation method can guide and enhance the effect of future spinescence application on segregating gratings engineering of expressway.

Qualitative Index

Since there are few methods to evaluate the qualitative index in dam safety monitoring and the evaluation system is imperfect, in this paper a new quantitative and comprehensive evaluation method for qualitative index is explored with the introduction of the method of interval marking, Set-Valued Statistics, grey theory and Jousselme distance function. Firstly, the interval marking method and Set-Valued Statistics are used to obtain the comprehensive quantitative value; then the evaluation class of the comprehensive quantitative value is quantified and the evidence vector is obtained through grey theory; next the weights of all qualitative indices are obtained through Jousselme distance function; finally the comprehensive influence of the qualitative indices on dam safety is determined by using the evidence vector and weights. The case study proves that this method is feasible which can reasonably determine the influence of qualitative index on dam safety.

Abstract Aiming at the problem of transformer condition evaluation, a comprehensive evaluation system for transformer noise is constructed according to the mechanism of transformer noise generation and propagation. Using matter-element theory and AHP, a state analysis method for transformer noise evaluation based on AHP matter-element model is proposed. The case analysis proves that the method is feasible for non-contact evaluation of transformer faults, and can accurately evaluate the state of the transformer, providing guidance for the operation and maintenance of the transformer.

The method to evaluate spacial schemes for public facilities is weighted average method, which was deduced to evaluate the spacial schemes of primary schools in Yuter community, and select the best one. For this purpose, investment coefficient, distance coefficient and enrolment proportion were introduced as the variables. According to the addition rule and the multiplication rule, the optimal scheme is the layout with one school. This weighted average method is effective and easy to be implemented in evaluation of spacial layout.
