Dam breach has catastrophic consequences for human lives and economy. In previous studies, empirical models are often, to a limited extent, due to the inadequacy of historical dam breach events. Physical models, which focus on simulating human behavior during floods, are not suitable for fast analysis of a large number of dams due to the complexities of many key parameters. Therefore, this paper proposes a method for fast evaluation of potential consequences of dam breach. Eight main indices, i.e., capacity of reservoir (CR), dam height (HD), population at risk (PR), economy at risk (ER), understanding of dam breach (UB), industry type (TI), warning time (TW), and building vulnerability (VB), are selected to establish an evaluation index system. A catastrophe evaluation method is introduced to establish an evaluation model for potential consequences of dam breach based on the indices which are divided into five grades according to the relevant standards and guidelines. Validation of the method by twelve historical dam breach events shows a good accuracy. The method is applied to evaluate potential consequences of dam breach of Jiangang Reservoir in Henan Province, China. It is estimated that loss of life in the worst scenario is between that of Hengjiang Reservoir and that of Shimantan Reservoir dam breach, of which fatalities are 941 and 2717, respectively, showing that risk management measures should be taken to reduce the risk of potential loss of life.

Background: An objective, comprehensive and scientific evaluation of emergency medical rescue capability (EMRC) is of great realistic significance in assisting the health administrative department to grasp the overall response capability of all emergency medical rescue teams, enabling each team to have a full understanding of its own strengths and weakness and improve itself accordingly. At present, the research on the evaluation of EMRC in Hazardous Chemicals Accidents (HCA) is not systematic and in-depth, and the existing research results also have some shortcomings, such as, the lack of strong theoretical support for the evaluation index system, the relatively single function of evaluation methods, and so on. Objectives: The objective of this article is to research the evaluation index system and a new evaluation method of EMRC in HCA to overcome the above shortcomings. Methods: It establishes an emergency medical rescue capability model by employing the competency model and then constructs the evaluation index system on the basis of the analysis of all the factors of emergency medical rescue capability in hazardous chemical accidents and sets up an evaluation model based on the theory of connection numbers and partial connection numbers. It determines the competence ranking of several emergency medical rescue teams and the competence state of an individual emergency medical rescue team by calculating the connection principal value, and it also predicts how the emergency medical rescue capability will develop based on the values of partial connection numbers. Results: The example shows that the calculation process of this model is relatively simple, and its assessment results are objective and authentic, and moreover, its multi-functions can make up for the deficiency of the simplified function of other evaluation models. Conclusion: This method is scientific and rational to some extent and can provide reference for evaluation problems of the same kind.

The uneven temporal and spatial distributions and the unreasonable development and utilization of water resources have caused increasingly severe water resources shortage around the world. Studying on regional water carrying capacity is beneficial for the optimal management of water resources, and can provide assistance for the sustainable utilization of water resources. The typical karst area in China – Guizhou province was applied as the research area in the paper. Meanwhile, twelve indexes were selected from three perspectives including water supply, water demand and social economy to establish the evaluation index system of regional water carrying capacity. Afterwards, the analysis hierarchy process was utilized to construct the evaluation model of regional water resources carrying capacity, so as to evaluate, compare and analyze the regional water carrying capacity in each city of Guizhou province, China. This model verified the feasibility of the evaluation method. Relevant studies can provide certain theory evidence and method support for the investigation on regional water carrying capacity.

The implemented performance of enterprise’s patent strategy is an important component to measure its comprehensive benefits. It is of strategic significance for an enterprise to evaluate objectively its implemented performance of patent strategy. From the perspective of sustainable development, according to the 4 aspects of creation, application, protection and management of patent, the essay constitutes preliminarily a comprehensive evaluation index system of the implemented performance of enterprise’s patent strategy which is composed of a set of 21 indexes on the basis of an amount of domestic and foreign literature survey, case study and expert consultation, and analyzes the evaluation model and method of implemented performance of enterprise’s patent strategy with the fuzzy comprehensive evaluation and through a real case. The essay thinks the constitution of evaluation index system should obey a series of basic principles of objectivity, systematization, science and conciseness and the evaluation in essence is multi-object, multi-factor and multi-layer. Therefore, it is effective and feasible to select the Fuzzy Comprehensive Evaluation method.
