Shipping Logistics Container Delay at LA Port 集装箱堆积在码头
Containers are unloaded in one day 集装箱一天内卸货完毕 The first containers off the ship are for inter-modal shipments 先卸下的货物 均属于?? These containers are stBaidu Nhomakorabeared in the “hot hatch” 这些货是从”优先”舱位内卸下来的 The balance of the containers are mostly stacked on the ground 其余的货然后才卸下,堆积在码头上 GE gets the OK to use the “hot hatch” for hot shipments GE得到允准, 紧急的货物可以进入”优先” 舱位

The team includes suppliers, 3rd party vendors, GE logistics people, finance, sales, and customers. 组成一个项目攻关小组，包括供应商、第三方供应商、GE物流人员、财务、销售和客户 The supply chain process is mapped from the supplier to the end customer 作出从供应商至终端客户的供应链流程 Measure Phase: 衡量阶段 The current performance is measured by looking at data from the previous 6 months. Capability of this process is 1.5 sigma 检查迄今6个月以来的数据以确定目前的表现，结果是这个流程的能力只达到了1.5
