模糊多维偏好群决策的BOT项目风险管理研究

运用模糊的语言变量进行多属性事物的群体评价决策,即模糊信息多维偏好群决策。由于BOT项目的风险结构十分复杂,如何对BOT项目风险进行有效的分级管理显得十分重要。系统地分析了BOT全生命周期风险的内容与属性,运用模糊决策理论和多维线性规划模型,结合改进的Borda分值法,构建了BOT项目生命周期的模糊信息多维偏好线性规划风险评价模型。模型中既考虑了决策者意见的一致性,又兼顾了决策意见的差异性,为BOT项目风险管理和评价提供了新的思路。     

国际市场进入模式的选择决策模型研究

经济的全球化和信息的迅速发展为企业的国际化经营创造了良好的条件。企业的国际化经营又在很大程度上依赖于国际市场进入的模式。基于国际市场进入模式对于企业经营发展的重要性,本文分析了国际市场进入模式的主要影响因素,并在此基础上构建一个较为全面的国际市场进入模式综合决策模型。在具体操作层面上,拟采用模糊数学的工具提出国际市场进入模式的识别模式,为企业的国际化经营的实施提供战略指导。     

基于模糊评价法的宜居社区评价研究

在21世纪人本主义回归的思潮下,“宜居”成为城市发展的关键词,而社区在宜居城市建设中发挥着越来越重要的作用.探讨宜居社区的评价指标,目的在于基于地方尺度和居民视角,识别社区发展面临的关键问题,并在为社区规划提供参考依据.采取强调居民主观感受的模糊评价方法,在北京市交道口街道通过分层抽样的问卷调查获得数据.结果表明,社区...     

基于新发展理念的安徽省高质量发展水平测度研究

安徽省的高质量发展水平测度对本省经济高质量发展有重要的实践意义,同时对其他省市的高质量发展有着重要的借鉴意义.本文在新发展理念的引领下,从创新驱动发展、区域协调发展、绿色发展、发展成果共享四个维度建立了综合的评价指标体系,利用熵权TOPSIS法进行赋权排序,对安徽省16个地级市的高质量发展水平进行了测度.在对得分进行分...     

基于模糊概念的可疑金融交易量化关联规则研究

从模糊集的基本理论入手,通过定义模糊概念软化属性域的划分边界,提出了一种新的基于模糊概念的量化关联规则方法.本方法克服了因划分区间而造成数据缺失的不足.最后通过将某市2004年的实际数据运用到建立的算法中,验证算法的有效性,为有效开展可疑金融交易识别提供了有益的参考.     

基于行为—结果—反馈的粤西北山区“十二五”高标准农田建设绩效评价及低效因子诊断

[目的]弥补现有绩效观的不足,提出并解析了基于行为—结果—反馈的土地整治绩效评价内涵,开展粤西北山区"十二五"高标准农田建设绩效评价及低效因子诊断。[方法]从实施行为、效益结果、调查反馈3个方面建立指标体系,采用熵权改进的TOPSIS法和障碍度模型量化评估绩效水平并诊断低效因子。[结果]粤西北山区各县市在组织实施、综合效益和调查反馈方面各有不足,"十二五"高标准农田建设绩效水平总体有待进一步提高,绩效评价结果具有显著的区域差异,罗定市绩效值最高,绩效水平为良好;英德市、蕉岭县、南雄市、仁化县的绩效水平为中级;郁南县、龙川县、始兴县、云安县的绩效水平为低级;对于粤西北山区大多数县(市),实施行为作为首位低效因子,对高标准农田建设绩效的贡献度最小。[结论]基于行为—结果—反馈的绩效观,采用熵权改进的TOPSIS法和障碍度模型的绩效评价,能够客观衡量研究区高标准农田建设绩效水平。增加田间道路建设、提高土地流转面积、加强专项工作经费落实对于提高粤西北山区高标准农田建设水平具有普适性。     

A fuzzy multi-criteria decision model for international tourist hotels location selection

The main purpose of this paper is to present a fuzzy multi-criteria decision making (FMCDM) model for international tourist hotel location selection. In this article we created 21 criteria for selecting the international tourist hotel location acquired from literatures review and practical investigations. And the methods of fuzzy set theory, linguistic value, hierarchical structure analysis, and fuzzy analytic hierarchy process are used to consolidate decision-makers’ assessments about criteria weightings. Finally, an empirical study for identifying the international tourist hotel location selection in Taiwan is conducted to demonstrate the computational process and effectiveness of FMCDM proposed by this paper.

Quality of service and segmentation in the MICE industry: An approximation based on fuzzy logic

This article aims to evaluate the service quality experienced at academic conferences held at the Universidad Técnica Particular de Loja in Ecuador. Our approach is based on fuzzy logic and ideal solutions to calculate a global attendee satisfaction index for specific market segments: Gender, nationality, and age. Current literature on the service quality experienced by conference attendees is still scarce. Our results show that the analyzed segments experience varying levels of satisfaction, and that the more influential attributes to each of them are also different. Our results can be applied to improve the competitiveness of Loja and that of Universidad Técnica Particular de Loja.     

Fuzzy Rasch model in TOPSIS: A new approach for generating fuzzy numbers to assess the competitiveness of the tourism industries in Asian countries

This study proposes a novel approach, the Fuzzy Rasch model, which combines Item Response Theory (IRT) and fuzzy set theory. This paper applies the Fuzzy Rasch model in Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to analyse the Tourism Destination Competitiveness (TDC) of nine Asian countries: China, Hong Kong, Japan, Korea, Malaysia, Singapore, Taiwan, Thailand and the Philippines. The study was conducted in 2009 using 6 criteria and 15 indices. The results demonstrate the feasibility of applying the Fuzzy Rasch model in TOPSIS to analyse TDC in Asian countries. In addition, the proposed model also provides an effective means of applying the MCDM method to study TDC. Furthermore, in 2009, the Asian countries were ranked from most to least competitive as follows: China, Japan, Hong Kong, Malaysia, Thailand, Singapore, Taiwan, Korea and the Philippines.
