Groupon模式下团购网站消费者信任度的模糊综合评价

Groupon模式网络团购的快速发展,是当前我国电子商务领域出现的新热点。虽然消费者信任度对于Groupon模式团购网站的发展有着重要的作用,但是当前还没有相关的研究文献。本文首先分析了影响Groupon团购网站消费者信任度的主要因素,然后用AHP和模糊评价分析建立了Groupon团购网站消费者信任度评价模型,最后以某团购网站为例,对其消费者信任度进行了评价。     

企业并购的财务风险评价研究

首先对企业并购中存在的对目标企业定价、并购融资、并购价值支付及在并购后对于目标企业的财务整合风险等财务风险进行了概述,在此基础上提出了企业并购决策中财务风险评价指标体系,然后构建了企业并购中财务风险评价的二级模糊综合评价模型。最后对运用一案例对财务风险评价模型进行了实证研究,验证了模型的可行性。     

The evaluation of forest crop damages due to climate change. An application of Dempster–Shafer method

In order to assess damage risk caused by climate change in forest areas, Dempster–Shafer theory of evidence and fuzzy measures were applied to develop a framework for the estimation of economic forest damage. According to the definition of risk supported by the Intergovernmental Panel on Climate Change, a function of hazard and resilience lines of evidence was defined. The results of the hazard and resilience assessment were used to develop an economic framework based on Faustmann studies. The evaluation model, implemented through a spatial analysis procedure, was carried out linking Faustmann formula with hazard and resilience raster maps. The model permitted to estimate in monetary terms two possible costs to be supported: the first one is expressed as the expected damage to the forest crop on the basis of the current obtainable woody assortments and the second one referred to the potential expenses to pay in order to mitigate the risk. Finally, the framework was tested on an area of central Italy (Tuscany region).

Anonymous social influence

We study a stochastic model of influence where agents have “yes” or “no” inclinations on some issue, and opinions may change due to mutual influence among the agents. Each agent independently aggregates the opinions of the other agents and possibly herself. We study influence processes modeled by ordered weighted averaging operators, which are anonymous: they only depend on how many agents share an opinion. For instance, this allows to study situations where the influence process is based on majorities, which are not covered by the classical approach of weighted averaging aggregation. We find a necessary and sufficient condition for convergence to consensus and characterize outcomes where the society ends up polarized. Our results can also be used to understand more general situations, where ordered weighted averages are only used to some extent. Furthermore, we apply our results to fuzzy linguistic quantifiers, i.e., expressions like “most” or “at least a few”.     

Valuation of Landmass Degradation Using Fuzzy Hedonic Method: A Case Study of National Capital Region

A Hedonic model to determine the revealed willingness to pay for landmass of different suitability classes, based on landmass functional characteristics obtained through subjective assessments, is developed for the National Capital Region in India. The inherent non-specificity involved in subjective evaluation is minimized using fuzzy logic based regression technique. The proposed fuzzy regression involves regression using central values of triangular fuzzy number and minimization of non-specificity using linear programming. The revealed willingness-to-pay for landmass of different suitability classes is used for valuation of disbenefits due to urban expansion on landmass of different agricultural suitability classes in National Capital Territory of Delhi. Appropriate pricing policies to prevent the future inappropriate landuse practices are developed using the landmass valuation.     

The impact of market freedom on the adoption of third-party electronic marketplaces: A fuzzy AHP analysis

Electronic-marketplace (EM) is an innovative model for interfirm transactions that are undertaken via the Internet. However, in view of higher investment costs and other associated risks, many small and medium-sized enterprises (SMEs), instead of establishing their own EMs, turn to adopt third-party-hosted EMs. In literature, most relevant studies to the adoption of the third-party-hosted EM were conducted on the research contexts of free market. Industries under the protection of government policies may have limited degree of market freedom, different from industries without these protection policies. Thus, this study intends to compare the decision choice of EM adoption between industries with various degree of market freedom. The decision choice of EM adoption consisted of many strategic factors that were constructed in terms of a three-layer hierarchical structure proposed in this paper. A fuzzy analytic hierarchical process (Fuzzy AHP) was utilized to estimate the relative importance of these individual strategic factors involved in the decision-making process of adopting third-party EMs. The research findings indicated there were some similarities and differences in the decision choice between the two industries of interest. The variety of market freedom can account for the differences in the decision choice of EM adoption. In addition to enhancing our understanding of the EM adoption decision of participative companies, the research findings also provide insightful information to third-party EM providers so that they may improve the effectiveness and efficiency of resource allocation.     

电子商务企业配送中心选址评价指标体系及模糊综合评价

电子商务环境下的物流配送中心选址涉及到多方面的因素,是一项复杂的系统工程。在建立选址模型时,很难将选址中的所有影响因素考虑周全,即使把这些因素考虑全面,也很难量化形成模型中的约束条件。所以,在进行电子商务环境下的物流配送中心选址时,应咨询和参考各相关专家的意见和建议,进行定性的选择。因此,提出模糊综合评价法来确定电子商务环境下配送中心选址方法。
