基于TOPSISI的空管运行单位安全能力分类评估研究

从空管一线运行单位的安全出发,考虑到航班量逐年递增以及各空管运行单位年飞行保障量存在较大地区性差异。为使各空管运行单位现有安全保障能力与其飞行保障量更好的匹配,将塔台、区域保障架次和跑道数量作为重要的属性来进行空管安全能力评估单位分类。运用已构建的评估指标体系,采用标准离差法-TOPSIS排序法,通过输出结果验证单位分类评估的合理性。

Hazmat facility location and routing analysis with explicit consideration of equity using the Gini coefficient

This paper develops a model to analyze facility location and routing decisions in the context of hazardous materials transportation. A novel aspect of this model is the explicit consideration of equity using the Gini coefficient, an established computation to evaluate equity. To solve the model, we develop a method that combines Lagrangean relaxation with column generation and illustrate that method using a realistic case study. We present a case study of hazardous material railway transportation with consideration of social horizontal equity categorizing the population by household income.

Determinants of website traffic: the case of European fashion apparel retailers

The globalization process together with the extraordinary growth in the use of Internet offer firms new growth opportunities. Retail firms are using a multichannel approach, involving the Internet, in their internationalization strategies. Website traffic as measured by unique users and online awareness is among the measures for assessing the success of the online channel. There is little evidence, however, linking website traffic and the characteristics of the retail multichannel internationalization process. In order to fill this gap, this paper analyses the factors explaining the retailer's international website traffic. Website traffic data for a sample of European fashion apparel retailers are modelled as dependent on characteristics of the organization and of its physical and virtual internationalization strategy. Following the results of several linear regression models, we infer the complementarity of online and offline channels in the international operation, as well as the contribution of social networks as traffic generators.
