Combining means-end chain and fuzzy ANP to explore customers’ decision process in selecting bundles

Although some researches had submitted the hierarchical model of customer value, there are still questions remaining in the model. How to achieve a more effective method for obtaining and analyzing data from customers concerning their expectations is still lacking. Therefore, this research first applied the modification of the means-end chain (MEC) to construct a hierarchy framework of customer value to allow product attributes to be linked. Next, this research combined fuzzy analytic network process (FANP) in exploring customer preference to catch the multiple needs of customers. Meanwhile, in the measurement of customer preference, fuzzy logic and linguistic variables are utilized to overcome human subjective and imprecise thinking. Overall, this research proposes the hierarchy framework of customer value including the causal relationships of attributes–consequence–value to fill previous model's gap, and identified the factors which could enhance the value of bundle, in contrast to the many monetary research treatments of product bundles. Finally, this research presented the value implications of cosmetics bundles and implication for management and marketing.

Mayer-Jensen shell model and magic numbers

Many nuclear models have been put forward since 1932. Among them the collective model proposed by Aage Niels Bohr and Ben Roy Mottelson and the nuclear shell model proposed by Maria Goeppert Mayer and Johannes Hans D Jensen are the two most successful models. A number of experimental facts like the existence of magic numbers compiled by Maria Mayer led to the discovery of the nuclear shell model. The addition of a nuclear spin-orbit coupling force to the mean field of the nucleons successfully predicted the nuclear magic numbers and many other properties of nuclei.

基于粗糙集和模糊聚类的网站日志数据挖掘实例分析

粗糙集理论是有效处理不精确、不确定和含糊信息的软计算工具,模糊聚类分析是依据客观事务间的特征、亲疏程度和相似性,通过建立模糊相似关系对客观事务进行分类的方法.网站日志数据通常是大量的,冗余的,日志中的页面之间的关系也是模糊的,不确定的.该文利用粗糙集理论和模糊聚类的方法对某学校网站的日志数据进行实例分析,抽取用户感兴趣的模式,理解用户的浏览兴趣行为,以便进一步改善网站结构,为用户提供个性化服务.
