![]() Products of the shipbuilding industry are characterized by huge volume, high specificity of a single ship, and a high degree of customization of parts, which creates challenges for ports and shipyards and makes the assessment of how to transport blocks in a effective way more difficult. However, shipbuilding differs from other manufacturing industries. Therefore, it is important that China masters the manufacturing technology required to build high-tech ocean-going passenger ships. In July 2017, the Ministry of Industry and Information Technology issued the Guide to Scientific Research Projects of High-Tech Ships (2017 edition), which clearly indicated the need to make advancements in the engineering design and construction technology of high-tech ocean-going passenger ships and to raise standards and improve intellectual property logistics management systems for the construction of such vessels.ĭue to the limited annual output of these ships globally, it is difficult for domestic enterprises to buy ready-made, second-hand luxury cruise ships that meet the needs of the Chinese market. The Made in China 2025 report issued by the State Council notes that the design and construction of high-tech ocean-going passenger ships is an important aspect of the development of Chinas shipbuilding industry. Influenced by positive factors such as national policy support and consumption upgrading, this market has strong market potential.Ĭruise ships are important cultural carriers on Chinas Maritime Silk Road and in other national strategies, and recent research has revealed that the Maritime Silk Road has influenced many areas and needs to be managed well. Although China is already the second-largest cruise market globally, the penetration rate of domestic cruise tourism is still less than 1%. The China Cruise Industry Development Report (2019) predicted that the scale of Chinas cruise market would reach 300 billion to 400 billion yuan in 2020. 2010–2019 global cruise passenger volume. ![]() The smaller the value of the objective function, the more the usage rate of a particular one (2) loading is the biggest obstacle to the overall working time of flat transporters, and a simple optimization model cannot solve this problem and (3) based on the optimization model, the load efficiency of flat transporters can be improved, and the delivery time can be reduced.įig 1. ![]() Three conclusions are reached: (1)The flat transporter utilization rate is inversely related to the value of the objective function. Based on organizing the various logistical processes for blocks and the circulation process in the shipyard, we established a model that takes the task time window and other factors as constraints, and minimizes the sum of delay time and no-load time of flat transporters while satisfying the punctuality of scheduling tasks. ![]() In this paper, the blocks and the flat transporters are the research objects. The reasonable use of methods to complete the transfer scheduling of intermediate products is of great importance. This is because ships like these tend to turn sideways at high speed, and you'll instantly lose a ship if it rolls over.Shipbuilding is a complex and large-scale operation involving many intermediate products (blocks) and the frequent transfer of blocks among workshops and stockyards. For example, ships like Brigantine that have side sails on the front and back can be quite annoying for this phase.
