In order to standardize public resource trading activities and improve the operating efficiency of public resource trading platforms, this paper conducts research on the performance of public resource trading platforms. A three-level and 28-dimension performance evaluation index system for public resource trading platform is established by considering the four levels of “input-process-output-effect.” Besides, entropy weight method, gray clustering, and fuzzy comprehensive evaluation are integrated on this basis. Entropy weight method is used to determine the index weight, and the degree value of membership for indexes on gray class is determined based on gray clustering method and converted into a matrix. Then, fuzzy comprehensive evaluation method is used to determine the evaluation value and finally carry out the platform performance evaluation, which provides theoretical support for academic researchers to conduct follow-up research on the performance evaluation of public resource trading platforms.

Maritime Boundary Delimitation

There are 11 provinces along the coastal regions in the Chinese Mainland and the scientific division of marine management boundaries among different provinces within the extents of the territorial sea is of important significance in promoting the sustainable development of the marine economy in China. A fuzzy evaluation index system that includes 14 indices of three subsets was established based on a case study of maritime boundary delimitation between Jiangsu and Shandong Provinces to evaluate the advantages and disadvantages of maritime boundary delimitation and determine the optimal scheme and offset shortages in the current evaluation index system and evaluation methods. Combined weights of indices were calculated through the analytic hierarchy process (AHP) and entropy weight method. The comprehensive evaluation indices were used to evaluate three maritime boundary delimitation schemes, namely, historical boundary delimitation scheme, angle bisector delimitation scheme, and equidistance delimitation scheme. Results show that the equidistance delimitation scheme is relatively superior to the two other schemes. The evaluation index is 0.504761 and the evaluation grade is “good”. The angle bisector delimitation scheme is the second optimal. The evaluation index is 0.361641 and the grade is “moderate”. The historical boundary delimitation scheme is the poorest. The evaluation index is 0.135345 and the grade is “poor”. In the late optimization of maritime boundary delimitation schemes, more consideration should be given to people’s livelihood and protection of national maritime rights and interests. The fuzzy comprehensive evaluation method based on AHP-entropy weight can not only provide a quantitative top-down sequence of schemes in terms of quality and solve estimation problems in maritime boundary delimitation scheme, but also assist decision-makers to select the best scheme. Therefore, it possesses great application values.

At present, the people in the micro-blogging marketing performance evaluation research is still in the weak status, based on the fuzzy theory, a comprehensive questionnaire with the method of entropy weight fuzzy comprehensive evaluation for the micro-blogging marketing performance in this study, with an enterprise’s from January 2019 to October of micro-blogging marketing performance activity, the propagation force and coverage for data collection and the analysis of simulation results. Fuzzy comprehensive evaluation is a method of comprehensively evaluating things based on the degree of membership in fuzzy mathematics theory. The method of evaluating participating units with multiple indicators can evaluate the participating units more reasonably and accurately. The entropy weight law reflects the relative variation degree of each indicator according to the amount of information provided by the observed value of each indicator, and calculates the weight data of the indicator by means of information entropy. Through the establishment of a performance evaluation index system for micro-blog marketing, the micro-blog marketing performance is researched on the three indicators of micro-blog activity, micro-blog communication power and micro-blog coverage in performance evaluation. Among the research results, 23% of people believe that micro-blog activity is more important for performance evaluation; 39% believe that micro-blog communication is more important in performance evaluation; 41% believe that microblog coverage is more important in performance evaluation. This result indicates that the marketing performance of the enterprise’s micro-blog is not only determined by whether the enterprise’s micro-blog is active or not, but also should pay attention to the spreading strength and coverage of the micro-blog. However, the influence of indicators with small weight on the marketing performance of the micro-blog should not be ignored.

This paper designs a comprehensive evaluation system of environmental performance fitting for the silicon production enterprise, and uses the entropy and fuzzy comprehensive evaluation method to assess and analyze the environmental performance of a silicon production enterprise A. Finally we find that A’s environmental performance is worse, and then on put forward some suggestions that may help to improve the enterprise’s environmental performance.
