Using simulation, we examine the decisions in moving freight between inbound and outbound trailers in a cross dock. The decisions examined include direct versus indirect handling of pallets, number of open receiving doors, door layout, number of forklifts, size of cross dock and freight mix. This study provides useful insights on handling freight in a cross dock. 相似文献

A supply chain using the cross‐dock approach can speed goods from upstream suppliers to downstream customers quickly and cost‐effectively, with benefits to the entire chain, if the appropriate type of cross‐dock is chosen and then designed, staffed and managed for effective performance. Unlike a warehouse, which offers storage, a cross‐dock is a high performance rapid transit point that does not provide storage. Although cross‐docks have been studied with some thoroughness, what has not been seen clearly is that a cross‐dock does not operate in isolation and therefore can't be optimized independently from the upstream and downstream processes. To be successful, cross‐dock optimization makes demands for high performance on all members of the supply chain in terms of speed, effective planning, high reliability, near error‐proof processes and a high degree of transparency, visibility and information‐sharing; accordingly, the article refers to this integrative perspective as a “cross‐dock based supply chain.” To make clear this interdependency between the cross‐dock and the chain based on it, a new definition that classifies types of cross‐dock based supply chains is offered. To assist scholars analyzing and industry management choosing a cross‐dock approach, cross‐dock based supply chains are classified as falling into three different types. Lastly, based on field work in industry and on literature review, nine critical success factors for cross‐dock based supply chain operations are offered. 相似文献

就真空管道运输实现以后,在未来物流体系中扮演的角色、定位,真空管道物流运输的特点、基本模式,真空管道货运车厢的设计与运行方式等进行讨论。研究认为:(1)真空管道运输将跟现有的水运、铁路、公路、航空运输业形成竞争,分流一定的货源;(2)真空管道运输是对现有运输方式的补充,虽然在部分功能上会发生替代,但是,真空管道运输不会取代铁路、公路、航空等运输方式;(3)真空管道货运车厢均须为全密封的,但不需要安装生命保障系统;(4)真空管道冷藏车厢的制冷系统在行驶过程中不允许跟管道真空环境进行气体交换,但真空环境是良好的绝热介质,在真空管道中运行的冷藏车厢恒温条件容易得到保证;(5)在规划设计真空管道运输系统时应考虑设置真空管道货运站。 相似文献

我国铁矿石码头布局现状分析 总被引:1,自引:0,他引:1
通过对我国铁矿石码头供需及布局现状的分析.总结出我国铁矿石码头布局存在着码头总体接卸能力不足、大型铁矿石专用码头不足、码头集疏运能力仍需改善三个主要问题.这对于解决目前我国进口铁矿石港口积压问题,降低铁矿石运输成本.满足未来我国进口铁矿石运输条件具有十分重要的意义.同时也为我国未来矿石码头的建设和布局规划提供了重要的理论依据。 相似文献
