Integration of a Multi-Stage Bulk Materials Acquisition System from the Viewpoint of Dock Operations     

Hong Tau Lee 《Marine Georesources & Geotechnology》2001,19(3):207-219

A multi-stage bulk materials acquisition system is examined from the viewpoint of dock operations. The whole process can be divided into four stages and treated as four subsystems: ships scheduling planning, material yard planning, dock arrangement, and material discharging. Since the structure and the complexity of each subsystem is different, the solution approaches applied are also different with respect to each. To increase operations efficiency and data consistency, an integration of the subsystems by coordinating the operations sequence and data communications for the four subsystems is discussed. The four subsystems are illustrated by using the material docks of China Steel Corporation, and the models developed in this research are also validated. The results indicate that the models developed are capable of deriving solutions better than the existing ones. Although the discussions are confined to China Steel Corporation, the models can be applied to other companies with similar operations.  相似文献

曹瑾  张卫锋  张汝祥 《云南地质》2021,(1):127-132

云南师宗县高良码头公路西侧古滑坡为一中型推移式土质滑坡,滑坡体规模30.8万m3.该古滑坡曾造成南盘江短期堵塞,之后古滑坡堆积体处在临界稳定状态.由于修建的省道S207公路从滑坡下部通过,古滑坡堆积体开始蠕动,2013年8月滑坡堆积体加剧蠕动变形,后缘弧状拉张裂缝及错台变形强烈.通过多次实地调查,激发古滑坡堆积体蠕动因...  相似文献
