Stowage method capable of improving mixed stowage sea transportation stability of various steel products

Abstract

The invention provides a stowage method capable of improving the mixed stowage sea transportation stability of various steel products. The method comprises the following steps: reading finished product information, seagoing vessel information and stowage requirement information from a port database; generating an initial stowage scheme; judging whether the stowage schemes are practicable or not by starting from the initial stowage scheme and according to ship head and tail balance limit and ship left and right balance limit, and optimizing the practicable stowage schemes through comprehensive stowage indexes to obtain the final stowage scheme; distributing a shipment serial number for each finished product; uploading the final stowage scheme information to the database, displaying the final stowage scheme information on a wharf storage yard terminal and a shore tackle terminal through network; and extracting the finished products according to the shipment serial number and by a storage yard crane, transporting the finished products by a truck to a wharf shore, and actually shipping by a shore tackle operator according to the obtained final stowage scheme. By the method, the stowage scheme is generated quickly according to the actual requirements of a transportation party and a loading and unloading party, and automatic stowage is realized.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a stowage method for improving the stability of mixed loading of various steel products by sea. Background technique [0002] Because of the low cost of sea transportation and large cargo capacity, the finished products of iron and steel enterprises are mainly transported by sea vessels. Various products are transported from the production plant area to the dock yard by off-site trucks. When the ship arrives at the dock, planners will The volume, load, arrival station and other information of the incoming ship and the information of various finished products allocated to it formulate a stowage plan. The plan determines the placement of finished products in the ship and the order of loading. After the stowage plan is issued, it will be stacked The yard cranes put the finished products into the trucks in the yard in turn, and then the trucks in the yard transport t...

Problems solved by technology

[0004] Compared with inland river ships, ocean-going ships have a huge capacity and can carry a large number of different types of steel products. Therefore, the scale of the problem to be solved is larger and the solution is more difficult. The current stowage plan of this type mainly relies on the terminal planner to communicate with the ship by phone. Negotiated and formulated, the efficiency is low and a scientific and reasonable stowage plan cannot be given, and transportation safety and quality are difficult to guarantee

At present, there are relatively few studies on the stowage problem of ocean-going iron and steel products. Patent No. 200510028376.4 "Steel Products Bulk Freight Ship Volume Stowage Method" has studied the problem of bulk loading of various products, but it does not consider the actual constraints such as the offset of the center of gravity of the ship and The placement information of each product is not given, which increases the difficulty of operation and affects the actual effect of the final placement

Patent No. 201310429869.3 "An Automatic Stowage Method for Improving the Stowage of Finished Products by Water" studies the stowage plan of iron and steel products, but this study only considers the situation that all products belong to coils, and does not consider the mixed loading of various finished products and The direction of product placement is different from that required for shipping by sea
