【摘要】：2003年以来,随着世界航运业的蓬勃发展,我国造船行业也进入了快速发展的时期,并在国际市场中逐渐取得了竞争优势,市场份额也逐步扩大,经济效益稳步提升。到2011年我国造船业的完工总量,手持订单量,新接订单量三项指标已连续三年占据全球首位。在我国造船业高速发展中我们也必须看到,我国大部分船厂仍然存在技术力量薄弱、精细化管理程度不够、生产效率低、资源浪费情况严重等问题。单从造船总量上来看我们虽然处于领先地位,但是我们在经济效益、设计能力、管理水平、生产效率等等这些关键指标上仍然与世界先进造船国家存在较大差距,生产就是要经济效益,如果没有了经济效益,那么企业的发展就会受到制约。近年来,世界经济持续低迷,在造船订单锐减,船舶造价持续走低的严峻形势下,如何加强造船企业的核心竞争力、加快产业升级是中国造船企业必须面对的问题,只有解决好这些问题,才能在行业洗牌中站稳脚跟,不被淘汰。船舶建造的特点是生产周期长、工序繁杂、工种繁多、工作量巨大,传统造船模式采取人海战术,试图以投入大量人力的方式加快生产进度,而对管理模式和工艺工法的研究和创新投入较少,这使我国造船企业与日、韩等先进造船国家相比失去了核心的竞争优势。造船生产效率低,直接导致生产成本增加、资源浪费,也会影响企业的造船总量和经济效益。本文以大船集团为背景,选取造船关键路径中的生产准备、计划管理、分段建造、总装阶段等方面存在的问题为切入点,利用诊断工具深入分析这些环节中存在的问题对生产效率、建造周期的影响,并对这些问题提出一系列的解决措施和优化方案来达到提高生产效率的目的。
[Abstract]:Since 2003, with the vigorous development of the world shipping industry, China's shipbuilding industry has entered a period of rapid development, and has gradually gained competitive advantage in the international market, and the market share has gradually expanded. By 2011, the total completion of China's shipbuilding industry, hand-held orders. The three indexes of new order volume have occupied the first place in the world for three consecutive years. In the rapid development of shipbuilding industry in China, we must also see that most shipyards in our country still have weak technical force and inadequate level of fine management. From the point of view of the total quantity of shipbuilding, we are in the leading position, but we are in the economic benefit, the design ability, the management level. There is still a big gap between the production efficiency and other key indicators with the advanced shipbuilding countries in the world. The production is to economic benefits, if there is no economic benefits, then the development of enterprises will be restricted in recent years. The world economy continues to be depressed, in the severe situation that shipbuilding orders decrease sharply and shipbuilding cost continues to decline, how to strengthen the core competitiveness of shipbuilding enterprises and speed up industrial upgrading is a problem that Chinese shipbuilding enterprises must face. Only by solving these problems can we stand firm in the trade shuffle and not be eliminated. Ship construction is characterized by long production cycle, complicated working procedures, various types of work and huge workload. The traditional shipbuilding mode adopts human wave attack, trying to speed up the production progress by investing a lot of manpower, but the research and innovation of the management mode and the process method are less, which makes the shipbuilding enterprises in our country. Korea and other advanced shipbuilding countries have lost the core competitive advantage. The low efficiency of shipbuilding production directly leads to the increase of production costs and waste of resources. This paper takes the shipbuilding group as the background, selects the production preparation, the plan management, the subsection construction, the assembly stage and so on in the shipbuilding key path as the breakthrough point. The effects of these problems on production efficiency and construction cycle are analyzed by means of diagnostic tools, and a series of solutions and optimization schemes are put forward to achieve the purpose of improving production efficiency.
