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.

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.

Combined with the development status of the green building industry in our country, this paper builds the evaluation index system of green building, and explores the network relationship among the indexes by introducing the network level analysis method, obtaining the weight coefficient of the different level index. Then on the basis of the weight size of each factor it determines the influence degree of each index on green building evaluation index system and the primary factor which has a great influence on green building evaluation index system, so as to provide the basis to find out the green building evaluation index system adapting to various types.

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.
