基于供应链管理的供应商综合评价与优化选择

现代企业的竞争已经转变为供应链之间的竞争,供应商评价选择是构建高效率供应链的重要环节.文章结合现时的市场环境,提出和确定了供应商评价指标,建立了供应商评价指标体系.从制造商的角度构建了一个对供应商的评价模型,并采用集成AHP和模糊综合评价的方法进行了优化选择研究.     

基于复杂网络和依赖关系的机电系统零部件重要性度量（英文）

针对当前已有重要性度量研究的局限性,提出一种基于复杂网络和依赖关系的机电系统中零部件重要性度量方法,该方法结合了机电系统零部件在系统中的功能角色及其在复杂网络中的拓扑位置.首先,探索了机电系统中零部件之间的依赖关系的表示和计算方法.其次,将机电系统中的零部件建模为有向加权依赖复杂网络(FDN),其中,点权由零部件在系统中的功能角色及其在复杂网络中的拓扑位置共同确定,而边权由零部件之间的依赖强度表示.考虑到PageRank算法无法计算零部件之间的依赖强度,在PageRank算法的基础上提出一种IPIM算法,该方法结合复杂网络的点权和边权,并考虑了机电系统中邻居零部件的重要性.最后,通过实例验证了所提方法的准确性,该方法能够有效地确定机电系统中零部件的重要性.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
