Description

Background
The ship has the characteristics of large volume, complex structure, various consumables, precise system, high price and the like, and the ship industry generally adopts single-piece small-batch production and has long manufacturing period. In general, shippers order a smaller number of ship types at a time than in the automotive aircraft industry, and order continuously only when the shipping market is high. In view of the characteristics of single-piece small-batch ship production, and the combination of the industrial characteristics of strong industrial relevance, large capital investment and small profit in the ship industry, the control of the shipyard on the steel cost is very strict, and the control is mainly reflected in the aspect of the utilization rate of the steel.
In order to improve the utilization rate of steel, each shipyard generally adopts a single-ship single-section self-adaptive multi-specification nesting mode to order the steel, and although the problem of the utilization rate of the steel is well solved, the multiple steel specifications bring about the phenomenon of uneven steel distribution, and then the situation of steel substitution during operation is caused, when the goods are in order, only goods can be accumulated, so that redundant inventory occupies the site, and then the shipyard rents the site to accumulate the redundant steel. In the series of processes, the design end repeatedly performs steel part typesetting for maximally utilizing steel, and the investment of the whole fund is about over 1000 thousands of the warehouse lease fee, the steel plate turning manual kinetic energy fee, the goods transportation fee, the pockmark polishing fee in the stacking period and the like of the material service end. Compared with the economic benefits brought by the improvement of the utilization rate of steel, the method is considered from the point of view of integrity, if the method is adopted, the utilization rate of steel resources is not enough, the manpower and fund overall arrangement of a company is not facilitated, the improvement of the economic benefits of each shipyard is not facilitated for a long time, and the high-efficiency and high-quality development of the shipping industry is also hindered. The following factors are mainly responsible for this phenomenon: (1) the planned resource goodness of fit is low, the ordering plan is not matched with the steel-making plan of a steel mill, so that the steel is not supplied in time, the load of cutting equipment of a shipyard is unbalanced, and the steel ordered to the mill is not required by operation segmentation, so that the steel is substituted to cause the phenomenon of cargo stock; (2) the steel products are various in specification and are made of the same material, the average thickness of each steel product is about 20-130, all the steel products are required to be prepared in 1-2 months, the ordering mode has extremely strict requirements on the steel making capacity of a steel mill, and a material purchasing department needs to find the steel mill to order all the steel products all over the world; (3) the method is influenced by the nesting mode of a single ship and a single section, the order of magnitude of parts of the single section is generally 500-1000, the plate thickness is about 5-20, the material is about 5-10, and various personalized steel specifications are easy to generate through the combination of the plate thickness, the material and the zero-order size, so that the unification or standardization of the steel specifications is not facilitated.
