模糊数排序法及其在房地产项目类型优选中的应用

针对层次分析法的不足，本文提出用五个三角模糊标度数来代替语言变量，以说明待选方案对评价准则的相对影响程度，通过比较方案与准则间的相互关系而得出模糊评判矩阵，评判矩阵与权向量相乘，可计算出各个方案的模糊数，再对模糊数进行大小排序而优选方案，将此法应用于优选房地产项目类说明了它的具体应用。     

对教师业绩综合评价模型化设想

本文利用数学方法构造了一个综合评价教师业绩的模型。本模型主要特点:1.从选择评价标志及确定各标志权重到给参评者计算评价值都采用数学方法处理,尽量避免主客观误差;2.建立了对评委的制约机制。

Stable partitions in a model with group-dependent feasible sets

Summary. In this paper we consider a model of group formation where group of individuals may have different feasible sets. We focus on two polar cases, increasing returns, when the set of feasible alternatives increases if a new member joins the group, and decreasing returns, when a new member has an opposite effect and reduces the number of alternatives available for the enlarged group. We examine two notions, stability and strong stability of group structures, that correspond to Nash and Strong Nash equilibrium of the associated non-cooperative game, and identify the classes of stable and strongly stable environments.Received: 29 June 2003, Revised: 17 February 2004, JEL Classification Numbers: C71, C72, D62, D71.The previos version of this paper has been written while the second author was visiting the Technical University of Dresden.

不同质条件下招投标双方的博弈研究

在无标底招标项目中,招投标各方之间存在诸多博弈现象。基于投标各方不同质的假设条件下,对招投标双方的博弈进行了深入地研究。利用价值效益评价决策的方法建立了招标方的评标计分模型和中标评价模型。根据招标方的评标偏好性,提出了招标方的评标策略集和中标策略集。同时制定在不同条件下的招投标双方最优中标策略和最优投标策略。

A linguistic decision process in group decision making

Assuming a set of linguistic preferences representing the preferences of the individuals, a linguistic choice process is presented. This is developed using the concept of fuzzy majority for deriving a collective linguistic preference, and the concept of nondominated alternatives for deriving the selected alternatives in the linguistic choice process. The fuzzy majorities are equated with fuzzy linguistic quantifiers. The collective linguistic preference is derived by means of a linguistic ordered weighted averaging operator whose weights are defined using a fuzzy linguistic quantifier. In order to obtain the nondominated alternatives, we present a novel reformulation of Orlovski's nondominance degree under linguistic information.     

An integrated novel interval type-2 fuzzy MCDM method to improve customer satisfaction in public transportation for Istanbul

In this paper, the problems of public transportation customers in Istanbul are addressed and their satisfaction levels are evaluated by using customer satisfaction survey and statistical analysis. A novel interval type-2 fuzzy MCDM method is proposed based on TOPSIS and GRA, to evaluate and improve customer satisfaction in Istanbul public transportation. Then, the criteria need to be improved are determined and different improvement suggestions are made for all public transportation firms.     

基于FAHP的民营企业融资效率评价

建立一个民营企业融资效率评价模型。通过建立民营企业融资效率评价指标体系,指出影响民营企业融资效率的因素主要有融资成本、融资结构、企业法人治理结构、资金利用率、融资机制规范度、清偿能力和宏观经济环境。另外,采用层次分析法结合模糊综合评价对民营企业融资效率进行综合评价,分析其结果,并用算例说明了该方法的实际应用。
