With respect to the multiple attribute decision making problems with linguistic preference relations on alternatives in the form of incomplete linguistic judgment matrix, a method is proposed to analyze the decision problem. The incomplete linguistic judgment matrix is transformed into incomplete fuzzy judgment matrix and an optimization model is developed on the basis of incomplete fuzzy judgment matrix provided by the decision maker and the decision matrix to determine attribute weights by Lagrange multiplier method. Then the overall values of all alternatives are calculated to rank them. A numerical example is given to illustrate the feasibility and practicality of the proposed method.  相似文献

Abstract:
Aimed at improving the simulation credibility of war complex system, the step-by-step control flow of war complex system simulation credibility was put up under the guidance of hierarchy principle, which improved the simulation credibility of war complex system by increasing similarity with the real war. Then, the war complex system simulation credibility control method oriented "data, model, simulation experiment process, and simulation application"—DMPA were built and expatiated. This method references the thought of industry production quality control to improve war complex system simulation credibility by reducing the influence of unauthentic factors. According to simulation practice, this method has preferable maneuverability and practicability.  相似文献

According to the aggregation method of experts’ evaluation information in group decision-making,the existing methods of determining experts’ weights based on cluster analysis take into account the expert’s preferences and the consistency of expert’s collating vectors,but they lack of the measure of information similarity.So it may occur that although the collating vector is similar to the group consensus,information uncertainty is great of a certain expert.However,it is clustered to a larger group and given a high weight.For this,a new aggregation method based on entropy and cluster analysis in group decision-making process is provided,in which the collating vectors are classified with information similarity coefficient,and the experts’ weights are determined according to the result of classification,the entropy of collating vectors and the judgment matrix consistency.Finally,a numerical example shows that the method is feasible and effective.  相似文献

The main faults existing in current scale methods are that the scales do not represent the real importance of alternatives and their relations. This paper presents a proportion judgment scale and introduces a new method based on the proportion scale for construction comparison matrix in the analytic hierarchy process (AHP). The proportion judgment scales do not have the faults existing in current scale methods and the comparison matrix constructed by the new scale  相似文献

This paper presents a new method for constructing synthetic matrix which is obtained by extending the given judgement matrices in the Analytic Hierarchy Process(AHP).The consistency relationship among the given matrices and therir synthetic matrix is studied.The method can be used to deal with situations where the number of the given alternatives is larger than nine,and needs less pairwise comparisons thanany others.Thus it will aid in the design of the AHP,which will reduce the information overload of decision maker,a major drawback of the original AHP algorithm.Finally,a numerical example is given to show the feasibility and effectiveness of the method.  相似文献

Structuring the hierarchy of a system is an important link of solving problems with the analytic hierarchy process. This paper gives and proves the two theorems about the relationship between the hierarchy and the reachability matrix of the system. On the basis of it, we propose a method of structuring hierarchy by directly using the reachability matrix of the system. This method is simpler and clearer than that of interpretive structural modeling and is suitable for both manual calculating and computer proceeding. It fully shows the simplicity of the AHP.  相似文献

1 IntroductionWe know that in order to obtain a superlinearly convergent method it is necessary to approximate the Newton step asymptotically (see [ll). How can we do this without actually evaluatingthe Hessian matrix by ally approximate to the Hessian matrix at every iteration? The answerwas discovered by Davidonl2] and was subsequently developed and popularized by Fletcher andPowell[3l. It consists of starting with any approximation to the Hessian matrir, and at eachiteration, updating th…  相似文献

Receding horizon H∞ control scheme which can deal with both the H∞ disturbance attenuation and mean square stability is proposed for a class of discrete-time Markovian jump linear systems when minimizing a given quadratic performance criteria. First, a control law is established for jump systems based on pontryagin’s minimum principle and it can be constructed through numerical solution of iterative equations. The aim of this control strategy is to obtain an optimal control which can minimize the cost function under the worst disturbance at every sampling time. Due to the difficulty of the assurance of stability, then the above mentioned approach is improved by determining terminal weighting matrix which satisfies cost monotonicity condition. The control move which is calculated by using this type of terminal weighting matrix as boundary condition naturally guarantees the mean square stability of the closed-loop system. A sufficient condition for the existence of the terminal weighting matrix is presented in linear matrix inequality (LMI) form which can be solved efficiently by available software toolbox. Finally, a numerical example is given to illustrate the feasibility and effectiveness of the proposed method.  相似文献

The uncertain multi-attribute decision-making problems because of the information about attribute weights being known partly, and the decision maker's preference information on alternatives taking the form of interval numbers complementary to the judgment matrix, are investigated. First, the decision-making information, based on the subjective uncertain complementary preference matrix on alternatives is made uniform by using a translation function, and then an objective programming model is established. The attribute weights are obtained by solving the model, thus the overall values of the alternatives are gained by using the additive weighting method. Second, the alternatives are ranked, by using the continuous ordered weighted averaging (C-OWA) operator. A new approach to the uncertain multi-attribute decision-making problems, with uncertain preference information on alternatives is proposed. It is characterized by simple operations and can be easily implemented on a computer. Finally, a practical example is illustrated to show the feasibility and availability of the developed method.  相似文献

在一个基于不确定型AHP方法的群决策过程中,现有文献对专家决策可信度的研究,亦即专家可信度的衡量,都是采取简单的算术平均法或加权平均法,是一种静态的权重赋权法,没有体现出专家间的动态盖异性.本文在综合运用可信度理论和不确定型AHP有关理论的基础上,提出了基于不确定型判断矩阵相似性和差异性的专家可信度的不确定型AHP方法.本文研究中,结合权重的主客观理论,得出不确定型AHP的最终权重,并将其应用到地基工程质量风险评价中,取得了比较理想的评判结果.  相似文献

基于判断矩阵的专家聚类赋权研究   总被引:5,自引:2,他引:3  
群组AHP评价方法研究中,现有赋权方法虽考虑了专家评判的具体内容的一致性,但缺乏对专家本身逻辑性的度量,以致可能出现虽然最后评判结果与群体共识相近,而评判结果并非完全为某位专家本意,却给予了与其他专家相同权重的问题。对此,提出了一种将判断矩阵赋权和专家聚类赋权相结合的方法,该方法采用聚类分析原理,将专家个体排序向量进行分类,根据分类结果和判断矩阵一致性确定专家权重系数。算例表明,该方法可行有效。  相似文献

AHP方法中判断矩阵的标度扩展构造法   总被引:22,自引:0,他引:22  
黄德才  郑河荣 《系统工程》2003,21(1):105-109
AHP在实际使用中常常因判断矩阵出现一致性检验错误而导致决策难产,且这个问题至今没有得到根本性解决,本文通过实例分析说明,导致一致性检验错误的根本原因是判断短阵的传统构造方法存在严重缺陷,它固化了选定的标度,使原先有差别的候选方案在比较过程中失去差别,因此,本文提出一种新的判断矩阵构造方法-标度扩展法,并证明该方法无论使用什么标度,所构造的判断矩阵都是完全一致的。故不需进行一致性检验且排序向量也容易获得,从而提高AHP方法决策的可靠性,并使AHP方法变得简便易行。  相似文献

针对基于语言判断矩阵的群决策逆判问题,通过对语言判断矩阵进行“量化”,将其转化成为互反判断矩阵,进而提出了一种依据数理统计理论的分析方法.该方法通过引进随机误差的概念,得出了一致性判断矩阵中元素的相对误差服从均值为零的正态分布的结论,进一步依据这一结论,根据各评判专家所提供的判断矩阵对专家们进行反判,即通过计算各专家的偏离度,对专家们进行排序,并且根据假设检验理论对排序进行检验、对专家们进行分类、最后用一个算例说明了该方法的有效性和实用性.  相似文献
