Evaluation model of venture investment based on fuzzy matter-element method of combined weight

Journal of Southeast University(English Edition) 2008年第S1期24卷 27-32页

作者： Meng Lin1 Bao Guangping2 Sun Yutao1(1 Department of Economics, Dalian University of Technology, Dalian 116024, China)(2 Finance and Taxation School, Northeast Finance and Economy University, Dalian 116025, China) Department of Economics Dalian University of Technology Dalian 116024 China Finance and Taxation School Northeast Finance and Economy University Dalian 116025 China

An evaluation model of an international venture investment project on the basis of fuzzy matter-element and combined weight methods is introduced. First, the compound fuzzy matter-element of optimal subordinate degree is constructed on the principle of the bigger-more-optimal or the less-more-optimal depending on the actual evaluation indicators, and combined with standard fuzzy matter-element to form a difference-square fuzzy matter-element. Secondly, a combined weight is calculated by both information entropy and the expert grading method. Finally, the compound fuzzy matter-element of Euclidian approach degree by M(·,+)method is constituted and used to classify venture investment projects. Based on the model above, six venture investment projects in a company are evaluated, and the results show that the projects are all good, which is demonstrated by the good income of the projects. Therefore, the coincidence of evaluation results and actual operation status indicates that the model is of great value in practical application.

Frontiers of Structural and Civil Engineering 2011年第1期5卷 105-111页

Taking account of the fuzzy results of the seepage monitoring analysis of roller compacted concrete(RCC)dam and uncertainties of the individual indicator evaluation,the fuzzy matter-element model of seepage monitoring of RCC dam analysis has been established with the use of the fuzzy matter-element analysis theory and the concept of euclid approach *** use of entropy theory can calculate the weighting factor through the disorder utility values of the information reflected by the data itself,which can effectively avoid the problems of weight distribution and uncertainties of subjective judgments of the seepage monitoring analysis of roller compacted concrete *** further the example shows that the analysis of entropy-based fuzzy matter-element analysis model of the seepage monitoring of roller compacted concrete dam is in accordance with the actual situation,which verifies the effectiveness of the method.

Optimizing selection of bridge raft based on fuzzy matter-element model and combination weighting

Engineering Sciences 2012年第1期10卷 61-64,96页

作者： Li Feng Shao Fei Wang Jianping Li Zhigang Engineering College of Engineer Corps PLA University of Science ＆ TechnologyNanjing 210007 China College of Mechanics and Materials Hohai University Nanjing 210098 China

It＇ s a necessary selection to support the maneuver across Yangtze River by floating bridge constructed by portable steel bridge and civilian ships. It is a comprehensive index for the scheme of bridge raft, containing a variety of technical factors and uncertainties. The optimization is the selection in the constructing time, quantity of equipments and man power. Based on the calculation result of bridge rafts, an evaluating system is established, consisting of index of spacing between interior bays, raft length, truss numbers, operation difficulty and maximal bending stress. A fuzzy matter element model of optimizing selection of bridge rafts was built up by combining quantitative analysis with qualitative analysis. The method of combination weighting was used to calculate the value of weights index to reduce the subjective randomness. The sequence of schemes and the optimization resuh were gained finally based on euclid approach degree. The application result shows that it is simple and practical.

物流管理 2011年第7期

作者：张诚

本文选取我国中部六省1998～2008年统计数据，采用模糊物元方法，对物流业就业人数、物流投资额、铁路线长、公路线长、中部地区客运量、中部地区货运量、邮路长度、载货汽车吨位、邮电业务总量等九个相关指标进行分析。文章对中部六省... 详细信息

本文选取我国中部六省1998～2008年统计数据，采用模糊物元方法，对物流业就业人数、物流投资额、铁路线长、公路线长、中部地区客运量、中部地区货运量、邮路长度、载货汽车吨位、邮电业务总量等九个相关指标进行分析。文章对中部六省物流能力值发展趋势的研究表明，投资及信息化水平对提高物流能力具有较大作用，而物流人才匮乏等因素则会阻碍物流能力的提升。为提升中部地区物流能力，推动中部地区经济发展，中部六省必须加大物流基础设施投入力度，保证投入资金的比重；加强中部地区物流人员的引进与培养，满足物流业人才的需求；逐步完成覆盖整个区域的现代化物流信息平台，广泛采用信息网络技术，实现资源共享与信息共用；加强资源整合力度，提高资源配置效益；加强省际交流与合作，共同致力于物流能力的提高。
