【摘要】：造船业实施业务流程再造(BPR)及优化(BPI),是理顺船舶建造流程,实现船舶建造均衡、有节拍生产的重要途径,也是我国造船企业实现跨越式发展,建立现代造船模式的必经之路。对船坞生产流程进行优化,有利于引进现代化造船生产管理模式,全面推动生产管理模式的转变,保持船坞搭载过程均衡、提高船坞利用率、提高船舶建造质量、缩短船舶建造周期和降低成本,增强企业的盈利能力和市场竞争力。因此,实施船坞生产流程优化,对切实促进企业发展具有重要意义。虽然目前我国造船企业已在建造总量取得领先地位,但是生产管理和生产效率与世界一流的造船企业相比还有很大的差距。尤其船坞作为造船企业的核心资源,坞期长、效率低是困扰我国造船企业长足发展的生产瓶颈。因此我们必须重视船坞生产流程优化,降本增效,才有可能实现由“量变”向“质变”突破,从而在激烈的竞争中赢得市场。本文拟运用精益造船理论,结合龙穴造船公司现有生产流程,分别从作业和管理两个角度,对快速搭载工法研究、精度管理研究、大型总段建造研究、船坞搭载网络研究、场地资源管理研究、环形搭载推进生产模式研究、建造生产节拍研究、出坞完整性状态管理研究等八个方面展开探讨,找出现有生产流程的问题和差距,提出优化船坞总装化造船生产流程的思路,达到最终缩短建造周期、降低生产成本、提高船坞效益的目的。论文从理论分析到现实问题剖析,再到对策和建议,以及策划建立新流程和实际应用评估,提出对船坞生产流程优化的一些想法。并通过实船建造实施状况,从船坞周期、搭载效率、完整性状态等经济性指标分析来验证新的生产流程体系的有效性与实用性,为后续局部流程的继续优化提供参考依据。龙穴造船公司的船坞生产在经过上述一系列流程优化后,逐步均衡有序,平稳提速上量,生产形势得到极大改善。
[Abstract]:The implementation of Business process Reengineering (BPRR) and the optimization of BPI in shipbuilding industry are the important ways to straighten out the ship construction process, realize the balance of ship construction and rhythmic production, as well as realize the development of Chinese shipbuilding enterprises by leaps and bounds. The only way to establish modern shipbuilding mode is to optimize the production flow of shipyard, which is helpful to introduce modern shipbuilding production management mode, to promote the transformation of production management mode, to keep the balance of dock loading process, and to improve the utilization ratio of shipyard. To improve the quality of ship construction, shorten the construction period and reduce the cost, enhance the profitability and market competitiveness of the enterprise. Therefore, the implementation of shipyard production process optimization, It is of great significance to promote the development of enterprises. Although China's shipbuilding enterprises have gained a leading position in the total amount of construction at present, But there is still a big gap between production management and production efficiency compared with the world-class shipbuilding enterprises, especially the dock, as the core resource of shipbuilding enterprises, has a long docking period. Low efficiency is the bottleneck of the rapid development of shipbuilding enterprises in China. Therefore, we must pay attention to the optimization of shipyard production process, reduce the cost and increase efficiency in order to achieve a breakthrough from "quantitative change" to "qualitative change". In order to win the market in the fierce competition. This paper intends to use lean shipbuilding theory, combined with the existing production process of Longxuan Shipbuilding Company, from the two angles of operation and management, research on the rapid loading method, precision management, Eight aspects, such as the research on the construction of large main section, the research on dock carrying network, the research on site resource management, the research on the production mode of ring carrying propulsion, the research on construction production rhythm, the research on the state management of dock integrality, etc., are discussed. In order to shorten the construction period, reduce the production cost and improve the efficiency of shipyard, the paper puts forward the idea of optimizing shipbuilding production flow of shipyard assembly, which can reduce the production cost and improve the benefit of shipyard. To countermeasures and suggestions, as well as planning to establish new processes and practical application evaluation, put forward some ideas for shipyard production process optimization, and through the actual implementation of shipbuilding, from dock cycle, loading efficiency, The economic index analysis, such as integrity state, is used to verify the validity and practicability of the new production process system, which provides a reference basis for the continuous optimization of local processes. After the shipyard production of Longxuan Shipbuilding Company goes through a series of process optimization, Gradually balanced and orderly, steady speed up, production situation has been greatly improved.
