目前,美国有大量的制造业企业在海外投资设厂,虽然有反全球化的现象,但这种趋势不会改变。美国有多种运输模式,这些模式是服务水平和价格的函数,订货至交货时间均值和方差的提高往往伴随着缓冲库存量和存货持有成本的增加。在供应链和物流研究方面,对不确定性事件和重大中断事件的研究以及对弹性供应链的研究是两个重要的研究方向,可以使企业能对高破坏性事件作出迅速反应,并从中迅速恢复。
At present, there are a large number of manufacturing companies in the United States investing and setting up factories overseas. Although there are anti-globalization phenomena, this trend will not change. The United States has a variety of modes of transport that are a function of service levels and prices. Increases in the mean and variance of time to delivery are often accompanied by an increase in buffer inventory and inventory holding costs. In the research of supply chain and logistics, the study of uncertain events and major disruptions and the study of flexible supply chains are two important research directions that can enable companies to quickly respond to high destructive events and quickly restore.
