s:In order to predict the harm of sudden pollution to source water,screen out appropriate emergency disposal technologies,an evaluation index system of emergency treatment technology in urban drinking water source based on threat evaluation was established by analytic hierarchy process (AHP) from the points of pollution situation,pollution position,water source scale,emergency management and alternative water source.Threat was divided into four levels, and different threat-levels corresponded with different weight of the evaluation index system of emergency disposal technologies. When pollution event occurred, emergency experts graded every index, got the threat-level according to the linear weighted method and selected corresponding set of weights of the emergency disposal technologies The method proved to be an scientific and accurate.

Fast and accurate threat evaluation (TE) of incoming air targets has a great influence on air defense. In this paper, two new generalized intuitionistic fuzzy soft set (GIFSS) methods are proposed for threat evaluation of air targets. Firstly, the threat evaluation index system is reasonably constructed by analyzing the relative kinematics between the targets and assets, apart from that between the targets and interceptors, which is more reasonable and practical. Secondly, after the threat indexes (TI) are properly obtained, two new aggregation operators for GIFSS are put forward based on the generalized λ-Shapley Choquet integral. The proposed operators not only depict the correlations among the evaluation index but also consider the importance of them globally. Finally, the effectiveness and superiority of the proposed methods are verified through a numerical simulation including four air targets in different index systems.

This paper has set an evaluation index system for "two-oriented society", which was divided into four levels. The factor analysis was adopted to find out the public factors of input indexes and output indexes about conserving resources and environment, then the scores of all public factors were calculated, and the construction conditions of our nearly 10 years "two-oriented society" were evaluated by using the data envelopment analysis. The conclusion was that the construction conditions of Chinas "two-oriented society" showed a rising trend which was at the expense of the coordinative development of the subsystems. At last, some suggestions were put forward.

Abstract. To achieve good water conservancy under the well-off society before 2020, the future water conservancy planning is undergoing in Yunnan Province. In this study, by analysing the research results of domestic relevant water evaluation index systems and combining this with the water conservancy construction key of Yunnan Province, an unique evaluation index system was proposed to evaluate the well-off water conservancy level of Yunnan Province. It is composed of three levels which are the target layer, criterion layer and index layer. And the criterion layer includes six systems, namely flood control and drought relief mitigation, reasonable allocation of water resources, highly effective water utilization, water source protection and river health security, water management and securing of water development. The analytic hierarchy process (AHP) was used to determine the weight of each index. According to the present situation of water development and the related water conservancy planning in Yunnan Province, the target value of each index and evaluation standards are put forward for Yunnan Province in 2020. The results show that the evaluation results are consistent with the actual condition of water development in Yunnan Province and can be used to examine the effects of well-off water conservancy planning.

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
