【摘要】：造船制造業(yè)是一個復(fù)雜的、科學(xué)的系統(tǒng)工程，產(chǎn)品導(dǎo)向型作業(yè)分解（ProductWork Breakdown Structure，PWBS）是現(xiàn)代造船模式下運作方法的基礎(chǔ)，關(guān)系到設(shè)計、制造和管理等方面。造船廠利用成組技術(shù)（Group Technology，GT）原理，以中間產(chǎn)品為導(dǎo)向，進(jìn)行細(xì)致的作業(yè)分析，通過分解和組合，均衡地安排生產(chǎn)和分配資源，從而不斷提高生產(chǎn)效率，縮短造船周期，降低造船成本，最終達(dá)到精益造船的目的。 在船舶制造過程中，管子的加工對于產(chǎn)品的周期和質(zhì)量均有較大影響，是除船體制造外第二個加工量最大的作業(yè)單元，管子制造計劃的保證，對船體各分道建造過程至關(guān)重要，如果不能保證預(yù)舾裝的順利開展，勢必增加船塢等后道作業(yè)負(fù)荷，會增加塢期，，甚至影響碼頭系泊試驗?zāi)酥猎嚭焦ぷ�，對船舶施工進(jìn)度造成影響。 本文首先通過相關(guān)文獻(xiàn)的研究和一些船廠的實地調(diào)研，闡述了國內(nèi)外管子制造的現(xiàn)狀，并對其歸納、整理和分析。其次，通過對作業(yè)分解結(jié)構(gòu)理論的研究，介紹了中間產(chǎn)品導(dǎo)向作業(yè)分解結(jié)構(gòu)的造船模式和成組技術(shù)的應(yīng)用。對于管子制造，提出了材料、尺寸特征和質(zhì)量特征是管子制造PWBS的三個核心要素，并通過管子制造的PWBS研究，展開了對上海外高橋造船廠管子制造的工藝性分析，包括管子制造工藝分解和分類成組的方法。本文圍繞管子制造的PWBS，用BP神經(jīng)網(wǎng)絡(luò)算法研究了管子制造定額工時的標(biāo)準(zhǔn)化，這對管子制造生產(chǎn)效率的提高具有積極的意義。 論文最后對本文的研究工作進(jìn)行了總結(jié)，并對以后的研究做出了展望。
[Abstract]:Shipbuilding manufacturing is a complex, scientific system engineering, product-oriented operation decomposition (ProductWork Breakdown Structure,PWBS) is the basis of modern shipbuilding operation method, related to design, manufacturing and management. Shipyards use the principle of group technology (Group Technology,GT), take intermediate products as the guide, carry out detailed operation analysis, arrange production and distribution resources in a balanced way through decomposition and combination, so as to continuously improve production efficiency and shorten shipbuilding cycle. Reduce the cost of shipbuilding, and finally achieve the purpose of lean shipbuilding. In the shipbuilding process, the pipe processing has a great influence on the product cycle and quality. It is the second largest processing unit except for the hull manufacturing. The guarantee of the pipe manufacturing plan is very important to the construction process of the hull. If the pre-outfitting can not be carried out smoothly, it will increase the working load of the rear track such as the dock, increase the docking period, even affect the dock mooring test and even the trial navigation work, which will affect the progress of the ship construction. In this paper, the current situation of pipe manufacture at home and abroad is expounded through the research of related literature and field investigation of some shipyards, and it is summarized, sorted and analyzed. Secondly, through the research on the theory of job decomposition structure, the shipbuilding mode and the application of group technology of intermediate product oriented job decomposition structure are introduced. For pipe manufacturing, it is proposed that the material, dimension and quality are the three core elements of pipe manufacturing PWBS, and through the PWBS study of pipe manufacturing, the technological analysis of pipe manufacturing in Shanghai Waigaoqiao Shipyard is carried out. Including tube manufacturing process decomposition and classification into groups. In this paper, the standardization of the quota man-hour of pipe manufacturing is studied by using BP neural network algorithm in PWBS, which has a positive significance for improving the production efficiency of pipe manufacturing. At the end of the paper, the research work of this paper is summarized, and the future research is prospected.
