基于模糊层次分析的网络服务级安全态势评价方法

针对缺乏网络服务级安全态势评价方法的现状,利用事件注入技术,充分考虑影响服务可用性与性能的重要因素,确立了反映网络服务级安全态势的三级指标体系,并提出一种基于模糊层次分析法(FAHP)的网络服务级安全态势评价方法,通过求出各指标对上一级指标的权重,结合多层次综合评价方法得到模糊最大隶属度向量,从而对网络服务级安全态势进行了量化分析。实验结果表明该方法能有效屏蔽具体服务及入侵行为细节,实现对网络服务级安全态势的定性描述和定量分析。     

房地产投资决策中的复合权重评价方法

为改进房地产投资决策方法,提出了以各权重向量偏差平方和最小为目标函数的复合权重方法.基于线性规划理论,从指标权重的确定入手,将主观赋权法(模糊层次分析,FAHP法)的主观权重和客观赋权法(熵分析法)进行有效结合,建立了基于复合权重方法的房地产投资决策模型,既能反映决策者的主观判断,又能反映客观数据的真实信息.具体应用表明,与其他复合权重确定方法相比,该方法简便实用,有效合理.

Determining the Critical Factors of Radical Innovation Using an Integrated Model of Fuzzy Analytic Hierarchy Process-Fuzzy Kano With a Case Study in Mobarakeh Steel Company

Understanding which radical innovation factor is of higher priority enables engineering managers to allocate the appropriate resources to innovation processes. The aim of this article is to develop a systematic approach for determining the most necessary factors affecting radical innovation. For this purpose, a model was proposed with the following three steps: (i) a comprehensive set of factors was extracted from the literature and customized for a case study company; (ii) quality attributes of the Kano model were applied and weighted as attributes for a fuzzy analytic hierarchy process; and (iii) the factors derived from the second step were weighted using a fuzzy Kano approach and then the critical or must-be factors were identified and weighted. All three steps have been examined at Mobarakeh Steel Company. Findings indicate that factors such as leadership and knowledge management are among the critical factors of radical innovation and must be improved to positively impact radical innovation. Prioritizing radical innovation factors enables engineering managers to allocate the appropriate resources to innovation processes.     

The low carbon development (LCD) levels’ evaluation of the world’s 47 countries (areas) by combining the FAHP with the TOPSIS method

The low carbon economy (LCE) is considered as a kind of development mode (low carbon development, LCD) in this paper. So several problems appear, e.g., what kind of development is LCD? And, how to evaluate the level of LCD? The aim of this study is just to answer these questions. Firstly, the indicators’ system of the LCD level was constructed, which contains five main indicators and 10 sub-indicators. Then, 47 representative countries (areas) worldwide were taken as the numerical case. In the empirical research process, a two step methodology of combining the Fuzzy Analytic Hierarchy Process (FAHP) with the Technique for Order Performance by Similarity to Ideal Solution method (TOPSIS) is proposed. FAHP was used to determinate the main and sub-indicators’ weights of the 47 countries’ (areas’) LCD level, then the TOPSIS method used these weights as its own input weights to complete the whole calculation process. The results indicate that the method proposed can be successfully used in the study and the concept of the LCD level be considered as a very useful tool because the conclusions related to it have some certain directive significances when we have to take decisions on some items. In the end, some reasonable policy suggestions are proposed and some directions for future studies are put forward.
