    When I was seven years old my mom was diagnosed (诊断) with cancer. The doctors told us my mom

might be saved with surgery (手术). But it could also kill her. She chose to have it.

    The day before the surgery I was off school, and my mom planned the best day of my life, everything I

loved at seven and everything that would put a smile on my face. The day began with her waking me up

saying, "Kate, I have a surprise for you. Come and see." The surprise was a doll I had wanted for the longest

time. Throughout the day, she told me everything that she thought I would need to know to grow up and be

a good person; she told me to be the best I could be and that I would always make her proud. We had a picnic

in the park, and it was so cold that we moved to the car. The day was filled with laughter. For the first time

in a long time I could see she was really happy. I would never forget her smile, or the way her eyes shone as

if we were the same age. It was the best day of my life, and I will never forget the conversations we shared. 

    My mother managed to live through the surgery. Now when I look back, I realize that the best day of my

life could be her last and this could be the last day I would remember with her, the last one we shared. I also

understand how unselfish a mother is.

问答题 案例分析题

海尔集团作为中国家电企业的龙头,是较早开始物流改革的。它希望通过物流重组增强企业竞争优势,有效地推动海尔的发展。海尔选择零部件作为主要突破口,建立现代化的立体库,开发库存管理软件,充分解决了零部件管理不先进、库存资金占用大的问题,使其达到最先进水平。随后向管理水平不能跟进的车间、分货方和经销商推荐先进的作业方法。机械化搬运和标准化包装随之出现,采用符合国际标准托盘和塑料周转箱。在上述问题有所改进之后,检验环节的问题暴露,检验时间长造成库存大量积压。海尔于是取消了检验环节,将之分散到供方和第三方仓库,大大的减少了库存量和库存资金积压,目前只有三天的库存量。海尔的物流发展计划实施了一年收到非常明显的效果,同时,海尔也利用第三方物流进行内部配送,通过企业物流整合社会力量。海尔实施物流的困难主要包括两方面。其一来自人们头脑中的习惯思维问题,大家的观念还是停留在是否能为自身带来方便的阶段。为此,海尔成立了专门从事物流改革推进的物流推进本部,由集团见习总裁亲自负责。包括采购、配送、运输三个事业部的物流推进本部使得采购、生产支持、物资配送从战略上一体化。其二是缺乏可以借鉴的相关经验,因此,海尔只能结合企业自身实际情况,在最短的时间内摸索出适应于海尔独有的物流管理模式。目前,海尔内部的物流事业部正在努力实现社会化,向其他企业提供服务,使海尔的企业物流最终成为海尔的物流企业。请回答下列问题:

(1)第四方物流是一个新兴的物流概念,请比较其与案例中的第三方物流有何区别?

(2)海尔若要开展第四方物流,你认为其关键是什么?
