In this paper, the model of multi-dimension grey evaluation is applied to assessment on the sustainable development situations of our country and their classification are divided Scientific foundation are provided to realize the sustainable development. The attempts of gray system method application in the sustainable development are done. 本文将多维灰色评估模型应用于可持续发展的评价 ,对我国可持续发展总体能力进行了多层次综合评估 ,在此基础上对我国可持续发展总体能力进行了分类 ,为灰色系统分析方法在可持续发展研究中的应用作了有益的尝试 ,评估结果为指导与调控我国可持续发展提供了科学依据。 To evaluate the EW equipment’ combat effectiveness, which is related to so many factors, is a complex question, in which the information about specification is incomplete and vague. The grey system theory is a powerful tool to settle the kind question. A grey evaluation system and model, based on the hierarchy structure for evaluating the combat effectiveness of EW equipment, are proposed and the evaluation algorithm is introduced.

To evaluate the EW equipment’ combat effectiveness, which is related to so many factors, is a complex question, in which the information about specification is incomplete and vague. The grey system theory is a powerful tool to settle the kind question. A grey evaluation system and model, based on the hierarchy structure for evaluating the combat effectiveness of EW equipment, are proposed and the evaluation algorithm is introduced. The evaluation approach is to establish an experts team whose task is to weigh and score each subsystem’ specification based on the tactical and technical specification of the EW equipment, and then to use the grey theory to deal with the data they determine, and consequently to gain the combat effectiveness. A simulation example is also given, which shows that the approach is brief and effective. This approach can be used to evaluate the combat effectiveness of EW equipment, as well as to compare like kind equipment, so that the EW equipment can be sorted based on the combat effectiveness. 电子战装备作战效能评估是一个十分复杂的问题,涉及因素多,而且部分因素存在信息不完全和不确定的问题,而灰色系统理论是处理这类问题的有力工具。提出了利用灰色系统的相关理论来评估电子战装备的作战效能,建立了基于层次结构的灰色评估指标体系,介绍了灰色评估模型和评估算法。最后利用 MATLAB 语言进行了仿真评估举例,结果表明该方法简单有效,不仅能评估单台电子战装备的作战效能,还能对同类型的多台装备进行作战效能的优劣排序。 An evaluating index system is put forward on the benefits of small watershed comprehensive controls on the Loess Plateau.Taking Zhuanyaogou watershed in northwest of Shanxi province as an example,the multidimensional gray evaluation model is used to evaluate the benefits of comprehensive controlling in 1989,1998 and 2010.The results show that the land area of high gray type and low gray type go up and the middle gray type land area rapidly goes down.At the same time,the development trend types on comprehensive... An evaluating index system is put forward on the benefits of small watershed comprehensive controls on the Loess Plateau.Taking Zhuanyaogou watershed in northwest of Shanxi province as an example,the multidimensional gray evaluation model is used to evaluate the benefits of comprehensive controlling in 1989,1998 and 2010.The results show that the land area of high gray type and low gray type go up and the middle gray type land area rapidly goes down.At the same time,the development trend types on comprehensive controlling benefits are divided.There are high stable type,low stable type,ascending type,descending type and unstable type.The low stable type and descending type are main types.New conception and new tactic should be applied in the future. 构建了黄土高原小流域综合治理效益评价指标体系,以砖窑沟流域为例,选择1989、1998、2010年3个时期,采用多维灰色评估模型进行小流域综合治理效益评价。结果表明,高灰类和低灰类的土地面积均为上升趋势,但高灰类上升缓慢,中灰类呈迅速下降趋势。同时,划分了综合治理效益发展趋势类型,即高稳定型、低稳定型、上升型、下降型和不稳定型,其中低稳定型和下降型的发展趋势成为流域的主要类型。今后的黄土高原小流域综合治理应采取新思路、新策略。图3,参13。
