Branding Strategies of Born Globals

Born global companies have now been studied for a decade. However, little has been written specifically about the challenges facing born globals in their branding endeavours. This research examines the branding strategies of 30 Finnish small and medium-sized born globals. The experience, qualities and global orientation of the founder and the top management team are found important for the success of the born globals in their branding achievements. A key argument is that business-to-business and business-to-consumer born globals differ as to their branding strategies and approaches. The analysis reveals a major imperative; branding strategies are dynamic and depend on the globalisation degree.     

Scarcity effects on sales volume in retail

Prior research provides controversial findings as to whether products become more or less desirable when accompanied by product scarcity. As there are many options relevant for retailing to generate product scarcity, it seems beneficial to identify the conditions under which scarcity should be applied as an instrument for sales promotion. We differentiate our considerations by the type of scarcity, the product category and by the existence of other purchase arguments for the scarce product. The main result of our empirical investigations is that these three conditions are relevant factors which influence the direction of scarcity's effect on product desirability.     

直扩系统中数字匹配滤波器的设计仿真

主要讨论了量化比特数和取样间隔对数字匹配滤波器（DMF）解扩电路性能的影响，通过直扩系统（DSSS）的仿真结果表明；DMF的量化比特数取3时，量化误差可忽略不计（近似为无穷量化结果）；而在低抽样率下依靠DMF的样值序列前端处理（FEP）可以使系统误码率达到高抽样率的效果，而硬件代价却大大减小。     

Measures of economies with an arbitrarily large number of equilibria

Balasko (1978) shows that in a compact subset of the space of economies, not too many economies can have too many equilibria. We extend Balasko’s result to the whole set of economies for a suitable measure. We show that the measure of economies with a large number of equilibria approaches zero as this number tends to infinity. An analogous result in the infinite‐dimensional setting is also established.     

基于旅游者角度的中国旅游区划分研究

根据游客消费行为特征中的旅游者访问频率、逗留时间以及旅游景点市场份额之间的关系,本文引入旅游显性比较优势、旅游位序比指数,采用四象限分类法将旅游区分为重点旅游区、深渊旅游区、崛起旅游区和传统旅游区四类。本文进一步结合Bulter的旅游地生命周期理论和Plog的旅游者心理学分类理论研究基于旅游者角度的旅游区划分在旅游市场营销中以及旅游流预测中的应用价值。     

基于灰色规划的物流联运方式选择问题研究

在物流管理中,联运方式已经成为物流运输的主要方式[1],而如何合理选择各运输方式的组合,也成为物流管理中的一类重要问题。本文根据各种运输方式的运输成本、运输速度等变量是不确定性的特点,首次引入灰色规划理论,对物流运输方式的组合问题进行了研究,建立了基于灰色规划的物流联运方式选择问题研究模型。并采用实例的方式,对此模型的不同定位规划问题进行了对比分析,结果证明了模型的合理性。     

多属性决策模型研究及应用

针对现实多属性决策问题的复杂性,提出了基于组合赋权和区间灰数的TOPSIS方法多属性决策模型。通过组合赋权确定权重并引进区间灰数描述决策者评价信息的不确定性,结合TOPSIS方法建立决策模型。最后结合实例证明该模型的有效性。     

基于模糊组合权的模糊TOPSIS方法在供应商选择中的应用研究

供应商的选择在供应链管理中是很重要环节,供应商选择的成功与否将直接影响到整个供应链的竞争优势,故有必要对供应商选择进行深入研究。本文将已有的模糊组合权方法和模糊TOPSIS方法相结合,提出一种基于模糊组合权的模糊TOPSIS方法,并将其应用于供应商的选择研究中。文章首先总结已有的相关研究结果,给出供应商评价的准则,接着介绍三角模糊数的相关理论,推出模糊组合权及模糊TOPSIS的算法步骤,最后通过一个算例验证方法的可行性。     

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。
