On the basis of the establishment of evaluation index system, an improved entropy weight – grey correlation – TOPSIS model is put forward to select project supply chain vendor, and process the related data. The each index weight is obtained from subjective weighting method and objective entropy method. The positive and negative distance between each evaluation object and ideal solution is calculated, and the grey correlation grade between each evaluation object and ideal solution is obtained. Then the relative closeness of each evaluation object can be gained that we can select the best vendor according to it.

The risk factors in the safety evaluation of antifloating anchor system of underground structure have the characteristics of complexity, grey, and fuzziness. Based on the Delphi method, analytic hierarchy process (AHP), and entropy weight method, this paper establishes a three-level evaluation index system based on four main risk factors and calculates the subjective and objective comprehensive weights of the index according to the comprehensive weighting method. It not only takes into account the valuable experience of the expert group but also reflects the objective impact of the subjective score on the system. On the basis of the above research, the grey-fuzzy safety evaluation method of antifloating anchor system is established by using the grey theory and the relevant theory of fuzzy mathematics. The reliability of the method is verified by an example, which has certain theoretical significance and application value.

In order to enhance the accuracy of regional disaster-carrying capability assessment, the dissipative structure of the regional urban earthquake relative disaster-carrying system is highly complicated and nonlinear. Moreover, the problem is multi-attribute, multi-index and multilevel. Based on the evaluation index system of regional relative disaster-carrying capability, This paper used the entropy weight assignment method to work out each index’s objective weight, quantitatively researched the 29 cities’ earthquake relative disaster-carrying capability, worked out every city’s relative disaster-carrying capability and divided its grades using the mean deviation method. The research results showed that the earthquake relative disaster-carrying capability of our country was much unbalanced. It was positively correlation with the economic performance, the eastern, central and western cities’ earthquake relative disaster-carrying capabilities were mainly distributed in the shape of the ladder. The eastern cities’ capabilities were much higher than the western cities’. So, we suggested that the eastern cities should further improve its earthquake disaster-carrying capability and the central and western cities should spend more efforts to develop its earthquake disaster-carrying capability. Only in this way, our country’s urban earthquake disaster reduction can develop evenly.

Index Weight

Entropy weight method (EWM) is a commonly used weighting method that measures value dispersion in decision-making. The greater the degree of dispersion, the greater the degree of differentiation, and more information can be derived. Meanwhile, higher weight should be given to the index, and vice versa. This study shows that the rationality of the EWM in decision-making is questionable. One example is water source site selection, which is generated by Monte Carlo Simulation. First, too many zero values result in the standardization result of the EWM being prone to distortion. Subsequently, this outcome will lead to immense index weight with low actual differentiation degree. Second, in multi-index decision-making involving classification, the classification degree can accurately reflect the information amount of the index. However, the EWM only considers the numerical discrimination degree of the index and ignores rank discrimination. These two shortcomings indicate that the EWM cannot correctly reflect the importance of the index weight, thus resulting in distorted decision-making results.

By proceeding from practice of the sunny sport activity in higher education institutes, the principles of selecting evaluation index of the campaign have been put forward. Base on the No.17 document of the central committee and related principles, the paper establishes the evaluation index system of the activity. Considering the difficulty of fuzzy synthetic evaluation method in calculation of the multiple factors and ignorance of the relationship among evaluating objects, a new weight evaluation process using entropy method is introduced. This improved method for determination of weight of the evaluating indicators is applied in synthetic evaluation of the sunny sport activity. Compared with the original evaluation method, the method predigests the fuzzy synthetic evaluation process greatly and the evaluation results are more reasonable.

In order to study the coupling coordination relationship, the equipment manufacturing industry has been taken as the example to develop the evaluation index system of producer services and equipment manufacturing industry through employing the entropy weighting method. The relationship between them has been verified in the whole country. The research results show that there is a symbiotic relationship between the producer services and the equipment manufacturing industry. Both of them are mutually promoted and symbiotically developed. The unbalanced economic development in all regions of China is dominated by the synergy degree difference of both sides, which provides the guidance for the regional economic development in our country.

Aircraft combat survivability is defined as the capability of an aircraft to avoid or withstand a man-made hostile environment, which has been increasingly important. In order to give a rational calculation of aircraft combat survivability, an integrated method based on combination weighting and multiattribute intelligent grey target decision model is proposed. Firstly, an evaluation index system containing susceptibility index and vulnerability index as well as their subindexes is established. Then a multiattribute intelligent grey target decision model is introduced. A combination weighting method is brought up based on a modified AHP (analytic hierarchy process) method and the entropy method, offering a rational weight for various indexes. Finally, utilize the multiattribute intelligent grey target decision model to assess the aircraft combat survivability of aircraft, verified by a practical case of five aircraft. The results show that the proposed method is effective and has a great value in engineering application, which will provide useful references for other projects’ evaluation.
