Abstract: With the rapid development of rail transit, it puts forward higher requirements for safety. Once a safety accident occurs, it is highly destructive. It is of crucial significance and value to ensuring the safety of urban rail transit network by constructing an effective safety evaluation system. For purpose of this study, an urban transit network safety evaluation system based on topological genetic algorithm was constructed with an example of urban rail transit networking. Four indexes of urban rail transit safety were determined with the literature analysis method in combination with expert scoring method, including network heterogeneity, travel efficiency vulnerability, connection …reliability and network capacity vulnerability. Besides, on the basis of some freeway networks and some freeway collecting toll data of Xi’an city, and the result of road network vulnerability, an index weight computing framework based on topological genetic algorithm was constructed. The result of simulation test shows that freeway manager should strengthen protection over nodes of large probability betweenness, and the urban transit network safety evaluation system based on topological genetic algorithm is of high feasibility and rationality.

Abstract: Teacher evaluation, an important part of teaching quality management, has an important impact on the cultivation of talents. As scientific and objective teaching evaluation can objectively measure the effectiveness of teachers’ teaching means, it is an important criterion for teaching authorities to evaluate teachers’ teaching methods as well as effective means and important ways to improve teaching methods. The evaluation method of traditional English teachers’ teaching ability is subject to subjective factors, which leads to unreliable evaluation results. This paper describes the use of data mining software Clementine to introduce data mining technology into teaching management, extracts useful information hidden …from teaching evaluation data, and explores key factors that influence the quality of teaching. Meanwhile, this paper anonymizes and encodes the data based on data mining technology, discretizes the teaching characteristic variables of English teachers with a large number of eigenvalues, processes teaching data by rough set reduction method, processes English teachers’ teaching database to be mined by rough set method, determines the decision table, sets minimum support and minimum confidence, obtains association rules through association rule mining method to realize English teachers’ teaching data mining, obtains the evaluation indicators through principal component analysis, calculates the English teacher’s teaching ability index, and evaluates English teachers’ teaching ability according to the index value at last. The experimental results show that the evaluation results of the proposed method are reliable and can reflect the true ability of teachers, thus providing a decision-making reference for the management of teaching authorities.

Abstract: Establishing an ecological responsibility system for resource-oriented enterprises aims to further encourage them to assume ecological responsibility. However, Chinese resource-oriented enterprises exhibit unsatisfactory ecological responsibility performance because they cannot ensure the smooth implementation of the ecological responsibility system. With considerations of the characteristics and detailed contents of ecological responsibility, an evaluation index system was established for resource-oriented enterprises, and their ecological responsibility performances were assessed using the intuitionistic fuzzy set–Technique for Order-Preference by Similarity to Ideal Solution method. Challenges of resource-oriented enterprises in ecological responsibility were recognized from the assessment results. Based on the findings, several policy suggestions were proposed …to ensure ecological responsibility performance among resource-oriented enterprises. Show more

Abstract: With the new round of scientific and technological revolution and industrial change accelerating, “electrification, intelligence, network and sharing” has become a new trend of the current automotive industry reform. Accelerating the cultivation and development of new energy vehicles has not only become an urgent task to effectively alleviate the pressure of energy and environment in China and promote the sustainable development of the automobile industry, but also a strategic measure to accelerate the transformation and upgrading of the automobile industry in China. In view of the low survival rate of high-tech innovating enterprises and high input and high risk of …high-tech enterprises, it is of great significance to assess and evaluate the operating efficiency of the high-tech innovating enterprises. This study used the entropy weight method to establish a DEA -based business performance evaluation index model to evaluate and analyze the business performance of the listed new energy vehicles enterprises in China in 2018. The result shows that most of the new energy vehicles enterprises are in the state of increasing returns to scale, conforming to the characteristic of high growth of high-tech enterprises; however, the overall operational efficiency of these enterprises is very low and some of them face the problem of obvious scientific research input redundancy; therefore, the improper input-output framework is the main reason lead to the low scale efficiency for the enterprises and provide corresponding policy proposals for these problems.

Abstract: At present, aircraft accidents caused by human factors occur frequently. As the flight crew is the last line of defense for aviation safety, how to identify and quantitatively evaluate human errors in flight and reduce the error rate has become an important issue for the civil aviation, and it is also the most effective way to control flight operation risks. Thus, the human error mechanism for pilot was investigated by the combine of the fault tree and the Bayesian network theories based on historical research data of typical unsafe events caused by flight human errors. Firstly, the fault tree was …used to identify and qualitatively analyze the risk of systems, and then transformed into a Bayesian network model to obtain the relative probability of intermediate events and top events. Finally, the system hierarchy of unsafe events caused by flight human error was quantitatively evaluated. The results showed that there were 96 failure modes in the system, and the flight human error was caused by the coupling of multiple risk factors. The probability of non-technical skill loss is the highest, followed by that of the lack of technical skills and violations. The basic events in the organization, environment and equipment factors have a great impact on the flight human error, which is a weak link in the system. The results provide some theoretical basis for developing preventive measures of flight human error and improving the level of flight safety. Show more

Abstract: Bibliometric analysis and information visualization software (Cite Space) were used to analyze and organize related research on whether people with the surname Yu descended from Temujin (Genghis Khan) of the Mongol nationality since 1981. Data were collected from the Chinese National Knowledge Infrastructure database, and analytic dimensionalities included basic knowledge of researcher, research institute, sampling of subjects, release time of research results, keywords and hotspot issues, critical cultural symbols, so on. Colleges, universities, and professors in Guizhou Province, China participated in the research, and few journalists also participated in many related surveys. The kernel keywords and critical symbols embodied in …the research were “Mongol Nationality,” “Genghis Khan,” “Tiegaiyu,” “Nine Sons, Ten Jinshi (successful candidates in imperial examinations),” among others. Related studies since 1981 are divided into four development phases and continue to present an expanding trend. Related mainstream viewpoints are divided into three types, namely, the Mongol nationality, Tangut people in the Western Xia Dynasty, and the Han nationality. Research arguments focus on whether people with surname Yu in southwestern China are descendants of Genghis Khan in Mongolia. Future research emphasis and difficulty lies in identifying if people with surname Yu in southwestern China are descendants of Genghis Khan in Mongolia, combining historical truths by processing and analyzing the enormous family trees with the surname Yu. Future research should focus on the emic approach. In the current study, paternal Y chromogene detection and related articles on migrants into Sichuan are predicted to facilitate further research development. Show more
