Abstract Ecological effect evaluation of water diversion is a difficult and long-term process requiring complex monitoring data and scientific evaluation method. Based on remote sensing data and the ecological investigation data of Yellow River delta, this study built a wetland ecology evaluation index system with the analytic hierarchy process (AHP) framework, which included 13 evaluation indices of three criteria as suitability, diversity, and functionality. Fuzzy-AHP comprehensive evaluation method was used to evaluate the ecological effect of water diversion at Diaokou River wetland restoration zone. The results show that the comprehensive evaluation index (CEI) of wetland ecology is 0.464 before water diversion, which belongs to the ‘poor’ level, while after five years of water diversion, the CEI increased to 0.737, which belongs to the ‘fine’ level. It represents that ecological water diversion has made prominent positive effects for the ecosystem of Diaokou River wetland restoration zone. The research result could give decision-makers a clear understanding about the ecological effect of wetland water diversion and provide scientific guidance for strategic decisions.

Constructing livable eco-civilized cities has become one of the important tasks of the reasonable planning of urban development. The construction of an ecological city aims to achieve the harmonious coexistence of society, resource, and environment. However, the current evaluation method system of an ecological building encounters problems from a defective evaluation index. Hence, a relatively perfect evaluation index system is built. First, the analytic network process (ANP) is combined with the existing standards online. Then, a rapid calculation of the index weight is performed using Super Decisions software. Based on the needs of complicated problems, the classical TOPSIS model algorithm is improved by introducing the weight coefficient; this improved TOPSIS algorithm is then taken as the core to build a whole set of comprehensive evaluation method system for ecological buildings. The ecological urban agglomeration in Qinling Mountains of Xi’an is used in this study as the example to perform verification in practice. Contrastive analysis is performed on the evaluation results of the new and old buildings using this method system; the results indicate that the ecological effect of the buildings in the new area is much better than that of buildings in the old area. These results are mostly consistent with the evaluation results given by the expert group. Thus, the comprehensive evaluation system proposed in this article is reliable, and effective, as well as practical to some extent. This method can be used in a wider range of building evaluation and further improved in future studies.

Power flow shift being one of the main reasons that cause a large-scale blackout of power system, it is important to get the power flow shift under control at the beginning of the failure. In view of multidrop overload which frequently occurs in power outage, a comprehensive evaluation method is proposed to control the power flow shift. This method synthetically considers the control nodes' ability to eliminate the overload of the transmission in combination with PCA in which nodes' sensitivity of branch is selected as the evaluation index, divides them into two types (nodes that increase the power output to branch and others that decrease the power output to branch) and then obtains the control nodes' operation sequence. Additionally, a reverse equal matching adjustment is used to realize the control over multidrop overload. Typical numerical example is used to verify the effectiveness of the comprehensive evaluation method.

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.

To utilize the objective information of index data and consider the important role of subjective judgment in the evaluation of distribution automation equipment testing results, a comprehensive evaluation method based on AHP (Analytic Hierarchy Process) and CRITIC (CRiteria Importance Through Intercriteria Correlation) method is proposed. Firstly, an evaluation index system of distribution automation equipment testing results considering seven big indicators and thirty-six small indicators is established. Secondly, AHP and CRITIC method are adopted to solve a practical evaluation problem of distribution automation equipment testing results. The subjective weights of each evaluation index are calculated by AHP, the objective weights of each evaluation index are calculated by the CRITIC method. Then, to achieve the sorting of distribution automation equipment testing results accurately, the comprehensive weights are obtained by combining the two weights. Finally, the analysis and comparison of case studies show that the proposed evaluation index system can accurately reflect the performance of distribution automation equipment and the comprehensive evaluation method of distribution automation equipment testing results which comprehensively considers the subjective comprehensive evaluation results.
