A Stowage Method for Improving the Stability of Mixed Shipping of Various Iron and Steel Products

Abstract

The invention provides a stowage method to improve the stability of mixed shipping of multiple steel products. The method: reads finished product information, seagoing ship information and stowage requirement information from a port database; generates an initial stowage plan; Starting from the stowage plan, the feasibility of the stowage plan is judged based on the bow and stern balance limits and the left and right balance limits of the ship. The feasible stowage plan is optimized through comprehensive stowage indicators to obtain the final stowage plan. ; Assign shipping serial numbers to each finished product; upload the final stowage plan information to the database, and display the final stowage plan information on the terminal yard terminal and shore crane terminal through the network; extract it according to the shipping serial number through the yard crane The finished products are then transported to the dock shore by truck, and the shore crane operator actually loads the ship based on the final stowage plan obtained. This method quickly generates a stowage plan based on the actual requirements of the transporter and loading and unloading party, and realizes automatic stowage.

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
