本研究的目的是為船舶之船段劃分進行優化分析。船舶在起建之初會針對船艙功能進行初步劃分，劃分出機艙段、船艏段、船艉段、住艙段等等。接著再依照建造廠房大小限制、人員施工需求、吊裝限制等等多方面向進行細部船段大小劃分，待劃分完成後再利用各個船段來進行工作排程來控管工期。良好的船段劃分不但可以梳理各船段工作順序以及重要性，更可減少各個施工環節所造成的浪費進而降低建造成本，反之，若是不盡完善的船段劃分可能徒增施工困難度，或是增加各類施工環節之成本，可見對於大型船舶之船段劃分研究有其必要性。
因目前國內缺乏船段劃分研究的相關文獻，各個船廠都根據以往的施工經驗來推算出適當大小的船段。目前最常使用的船段劃分法為廠房極限劃分法，這種方法是根據廠房極限的大小來進行分割。雖然這種方法可以最大程度地利用廠房產能，但現今的船舶設計不斷推陳出新，這種方法切割出的船段龐大，如果面臨設計變更需求時，可能會對廠房的功能及整體施工流程造成嚴重的影響。因此，研究適合現今船型設計的船段劃分方法至關重要。
本文將探討船段劃分的基本法則以及船段製作的流程進行分析，首先使用六何法定義問題，並使用魚骨圖及根源衝突法找出改善及惡化要素，再利用萃智理論中的矛盾矩陣及創新發明原則對各功能船段進行船段劃分優化分析，研擬出全新的劃分準則並進行模擬後得知減少了40%的修改次數，在設計、施工等成本上也有卓越的經濟效益提升。

This thesis mainly discusses the optimized analysis of block arrangement of a ship. At the beginning of shipbuilding, the ship will be initially arranged from a functional perspective, including engine room construction, fore construction, bow construction, superstructure, etc. The detailed block arrangement inside the ship will then be separated according to the size limit of the shipyard, personal working requirements, hoisting restrictions, etc. After the design of block arrangement is completed, the estimated schedule of each block will be used to control the overall timeline of the shipbuilding process.
A good block arrangement can not only streamline the shipbuilding work sequence, but also reduce material waste caused by each block, thereby reducing overall costs in shipbuilding. Conversely, if the block arrangement is not designed optimally, it may increase the difficulty of shipbuilding or result in increased costs for each part during shipbuilding. In summary, studying block arrangement is essential for shipyards.
Currently, there is a lack of relevant literature on ship block arrangement methods. Therefore, each shipyard designs the appropriate size of ship blocks based on past experience, commonly using the shipyard's size limitations as a reference. While this method maximizes the use of shipyard capacity, ship design and development are constantly evolving. If shipyards continue to use outdated block arrangement methods, production may be delayed due to design revisions. Hence, it is crucial to study block arrangement methods for ship design.
This research will discuss the rules of shipbuilding and ship block arrangement, analyze the shipbuilding production process, and utilize TRIZ theory for optimization analysis of each functional ship block.
This thesis will discuss the rules of shipbuilding and ship block arrangement. First, the 5W1H method will be used to define the problem, and then the fishbone diagram and root contradiction analysis will be used to identify improvement and deterioration factors. The interactive contradiction matrix and innovative invention principles from the TRIZ theory will be utilized to optimize the arrangement of various functional sections of the ship, and a new arrangement criterion will be developed. Simulation results show a 40% reduction in modification times, as well as a significant increase in economic benefits for design and construction costs.
