【摘要】：船舶管系設(shè)計是船舶總體設(shè)計的主要內(nèi)容之一,良好的管路布局結(jié)果不僅需要有豐富管道設(shè)計經(jīng)驗的專家或工程師參與,而且還需要一套良好的管路設(shè)計方法。良好的管系設(shè)計方法在船舶管系設(shè)計中占有舉足輕重的地位,它對提高船舶管系設(shè)計質(zhì)量,縮短船舶總體設(shè)計周期,提高船舶設(shè)計建造效益等意義重大。但在現(xiàn)實管路設(shè)計中,由于管路系統(tǒng)本身的復雜性,使得船舶管路自動化設(shè)計變得極度困難,基于此,本文提出了基于人機合作的管路布局優(yōu)化設(shè)計方法來對船舶管路三維布局優(yōu)化設(shè)計問題進行研究。 船舶管系設(shè)計主要有三個方面,分別是單條管路的布置設(shè)計,多條管路并行布置設(shè)計以及分支管路的布置設(shè)計,本文重點對單條管路布置設(shè)計和多條管路布置設(shè)計方法進行了深入研究。管路布置設(shè)計問題屬于NP-hard問題,近幾年有不少學者應用智能優(yōu)化算法對該問題進行研究,并取得了一定成果,但這種僅靠算法迭代求解布置管路的方法,在算法迭代求解過程中,缺少了設(shè)計者的參與,算法的收斂性能具有局限性,為了改善算法的收斂性能,本文提出了基于人機合作的船舶管路三維布局優(yōu)化設(shè)計方法。針對該研究內(nèi)容,本文研究了船舶管路布局設(shè)計的人機合作機理,闡明了人工個體的獲取方法及加入原則,結(jié)合船舶管路布局特點,提出了基于人機合作的改進蟻群算法,給出了基于人機合作的管路布局優(yōu)化蟻群算法步驟,詳細描述了基于人機合作的蟻群算法在船舶管路三維布局優(yōu)化設(shè)計問題中的應用過程。 另外,通過仿真實驗驗證了在蟻群算法基礎(chǔ)上結(jié)合人機合作操作能夠較好地解決單條管路三維布置的設(shè)計問題,設(shè)計效果優(yōu)于僅利用人工智能優(yōu)化方法的設(shè)計結(jié)果；將生物學中的協(xié)同進化算法應用到三維多管路并行布置設(shè)計問題中并結(jié)合人機合作的思想,能夠較好地對該問題進行求解。這種基于人機合作思想對管路布局進行優(yōu)化設(shè)計的方法將為開辟新的管系設(shè)計思路提供一定的參考價值和指導意義。

[Abstract]:Ship piping design is one of the main contents of ship overall design. Good pipeline layout results need not only experts or engineers with rich pipeline design experience, but also a set of good pipeline design methods. Good piping design method plays an important role in ship piping design. It is of great significance to improve the quality of ship piping design, shorten the overall design cycle of ships, and improve the efficiency of ship design and construction. However, in the real pipeline design, because of the complexity of the pipeline system itself, the automatic design of the ship pipeline becomes extremely difficult. Based on this, this paper proposes a pipeline layout optimization design method based on human-computer cooperation to study the three-dimensional layout optimization design of the ship pipeline. There are three main aspects in the design of ship pipeline system, which are the layout design of single pipeline, the parallel layout design of multiple pipelines and the layout design of branch pipeline. in this paper, the layout design of single pipeline and the layout design method of multiple pipelines are studied in detail. The problem of pipeline layout design belongs to NP-hard problem. In recent years, many scholars have studied the problem by using intelligent optimization algorithm, and some achievements have been made. However, in the process of iterative solution of pipeline by algorithm, there is no participation of designers, and the convergence performance of the algorithm is limited. in order to improve the convergence performance of the algorithm, In this paper, a 3D layout optimization design method of ship pipeline based on man-machine cooperation is proposed. In view of this research content, this paper studies the man-machine cooperation mechanism of ship pipeline layout design, expounds the acquisition method and addition principle of artificial individual, combined with the characteristics of ship pipeline layout, puts forward an improved ant colony algorithm based on human-computer cooperation, and gives the steps of pipeline layout optimization ant colony algorithm based on man-machine cooperation. The application process of ant colony algorithm based on man-machine cooperation in 3D layout optimization design of ship pipeline is described in detail. In addition, the simulation results show that the combination of ant colony algorithm and man-machine cooperation operation can solve the design problem of three-dimensional layout of single pipeline, and the design effect is better than that of artificial intelligence optimization method. The co-evolutionary algorithm in biology can be applied to the parallel layout design problem of three-dimensional multi-pipeline and combined with the idea of human-computer cooperation, and the problem can be solved well. This method of optimizing pipeline layout based on the idea of man-machine cooperation will provide certain reference value and guiding significance for opening up new ideas of pipe system design.
