仓储是物流运作的基础,随着我国经济的发展,对物流、仓储业务的外包需求逐步增多,中小物流企业对仓储租赁的需求也日益强烈,仓储业面临着越来越大的发展空间.但是我国的仓储业在运作方式和设施上存在大量的弊端,严重影响了物流成本与费用的节约水平,尤其是盲目引进国外技术与理念,造成生搬硬套现象严重,妨碍了我国仓储业的健康发展,因此在提高服务水平,降低库存,节约时间,成本最小化的压力下,仓储管理显然是越来越重要了. 相似文献

自动化立体仓库作为现代物流技术领域内出现的一种新型仓储方式,在工业生产中发挥着日益重要的作用。自动化立体仓库作业调度往往需要多巷道堆垛机联合作业,根据作业调度相关原则,提出基于时间要求的堆垛机调度算法模型和优化调度的三个目标,运用遗传算法实现多目标的优化,采用矩阵编码和不同目标互相交叉的方法,解决多巷道堆垛机联合作业优化调度问题,突破了传统的仅对单目标进行优化的特点。 相似文献

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? 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
