Catastrophe Progression

As an effective measure to reduce energy and material consumption, green building has drawn much attention all over the world. Under the background of ecological city construction, the development speed of green building is extremely high in China. However, it is unclear about the overview of regional green building development. This study puts forward an evaluation model to scientifically measure the regional development of green building. The rough set theory and the catastrophe progression method optimized by entropy method are utilized in the model. A case study is conducted to clarify the application of the evaluation model, and the spatial distribution of regional green building development in 2015 is shown in the end. The result shows that the evaluation model is scientific and applicable. The spatial distribution of green building development in China was uneven. Green building development concentrated on the Beijing-Tianjin-Hebei area, Jiangsu-Zhejiang-Shanghai Area, Guangdong and Chongqing. Tibet was almost the bottom in every aspect, but it performed the best in economic efficiency. This study not only contributes to the research area of green building development, but also helps to promote green buildings in practice.

Development Capability

In order to alleviate the pressures of environmental pollution and the energy crisis, and to lay out and capture huge emerging markets as soon as possible, all countries in the world are vigorously developing new energy vehicles (NEVs). This paper analyzes the factors influencing the development capability of the NEV industry from the aspects of autonomy, controllability, and stability, and constructs an evaluation index system. Based on the improved entropy method and the catastrophe progression method, we establish an evaluation model for the development capability of China’s NEV industry and comprehensively evaluate the development capability of 15 new energy auto companies. An empirical analysis finds that the outlook for the overall development capability of China’s NEV industry is not optimistic, and there is a big gap in the industry, lacking core technology and independent innovation capability. We propose countermeasures such as increasing research and development (R&D) investment and innovation, and improving policy support.

The hidden costs due to the current evaluation model for green building lacks relevance, and therefore this paper, fuzzy comprehensive evaluation method, From the three major aspects of business, users and social selected 16 indicators of the operational phase of the hidden costs of starting to build a green building implicit operational phase cost evaluation model through structural entropy method will combine objective assignment method and subjective assignment method to determine the evaluation index weights, In order to achieve the operational phase of the project the green building real-time monitoring of hidden costs. The results show that the hidden costs of green building evaluation index for multi-operational phase problem, the method can be more objectively and accurately reflect the size of the extent of its hidden costs.

Public Transportation System

The basic principle of matter element analysis theory was applied to establish the multi-level extensible evaluation model of advanced public transportation system. First, evaluation index system was established from three aspects, the transit technology level, economic benefit, social benefit and environmental impact. Then, according to the characteristics of evaluation indexes on different levels, entropy method and AHP was respectively used to determine the index weight value. Grade of evaluation was given by calculating relational degrees by layers. Finally, APTS in a city was studied as an example, and improvement measures were put forward. The method is proved to be reasonable and valid.

Green construction plays an important role in the formation of green building. For the characteristics of fuzziness and incompatibility, this paper introduces the theory of fuzzy matter-element into the evaluation of green construction. The power weight is worked out with the entropy method, the related degree values between the standard fuzzy matter-element and each fuzzy matter-element is established, it lines up each scheme to pick up the best scheme. The result shows that among the methods of multiple indexes comprehensive evaluation of green construction, this method can reflect the extent of green construction objectively and accurately.

The safety of urban human settlements has ever aroused extensive attention of the whole world. And the safety of urban human settlements and the evaluation are scarcely studied. The safety evaluation index system of urban human settlements was put forward, the safety evaluation model based on the catastrophe theory and GIS technology was built up. And the model was applied in the case study of cities in Sichuan Province. According to the above index and catastrophe progression method, the scoring and ranking of every 17 indicators of the safety evaluation in 18 prefecture-level cities in Sichuan Province were calculated. Finally, the grading map of the safety evaluation of Human Settlements in Sichuan Province was obtained. The results showed that the evaluation result is basically accordant with people's perceptions. According to concrete conditions of different cities, it should make corresponding measures and analyze deeply to get the scientific and feasible scheme.

The development of the economic system is affected by many factors, and the stability of the traditional economic analysis model is difficult to maintain. In order to explore the efficient and stable economic system evaluation and analysis model, based on machine learning ideas, this study uses rough set algorithm as the basic algorithm, and applies the related methods of rough set and catastrophe model theory to the evaluation of ecological economic development level. Moreover, this study reduces the redundant index of the index system and calculates the importance of the index after reduction. Based on the catastrophe set model, this study uses MATLAB software programming to comprehensively quantify the ecological economy, and finally divides the ecological economic grade. In addition, this study combines rough set theory with fuzzy mathematics, and initially establishes a two-branch fuzzy evaluation model. Finally, this study combines the actual situation to use the established model to evaluate the regional eco-economic system. The research results show that the method proposed in this paper has a certain effect, which can provide a reference for subsequent related research.

Catastrophe Progression

This study proposes a new comprehensive evaluation method with principal component reduction and catastrophe progression method, considering the complexity, hierarchy, contradiction, and relevance of the factors in sortie generation of carrier aircrafts. First of all, the index system of sortie generation capacity is ascertained, which contains correlative indexes. The principal component reduction method is applied to transform the correlative indexes into independent indexes. This method eliminates the effect of correlativity among indexes. The principal components are determined with their contributions. Then the reduced principal components are evaluated in catastrophe progression method. This method is easy to realize without weights, which is more objective. In fact, catastrophe progression method is a multidimensional fuzzy membership function, which is suitable for the incompatible multiobjective evaluation. Thus, a two-level evaluation method for sortie generation capacity of carrier aircrafts is realized with principal component reduction and catastrophe progression method. Finally, the Surge operation of aircraft carrier “Nimitz” is taken as an example to evaluate the sortie generation capacity. The results of the proposed method are compared with those of Analytic Hierarchy Process, which verify the usefulness and reliability of the proposed method.
