【摘要】：国内LNG行业经过10余年的发展,已累计建成32台大型LNG储罐,预计未来其建设数量仍会呈现大幅度增长。随着项目特征的改变、业主单位多方位需求和期望的提高,如何科学地选择一个适合项目的发包模式,在维护业主利益方面具有重要的影响。本文在现有多种工程发包模式的基础上,通过运用层次分析法研究分析适合大型LNG低温储罐工程的发包模式。首先,通过对国内外已建成的LNG储罐工程的发包模式以及国内广泛应用的发包模式进行对比分析并结合业主单位能力的现状,确定了DBB模式、EPC总承包模式、CM模式以及EP+C模式四项作为分析研究的备选方案层;其次,通过文献研究、专家咨询和判断,确定了5个准则层一级指标和14个子准则层二级指标,并完成大型LNG储罐工程发包模式选择层次结构模型的构建。最后,基于层次结构模型设计问卷,并向选定的专家发放问卷调查以获得判断矩阵基础数据,运用软件分析计算出5个准则层及14个子准则层指标的权重,并进一步计算得到方案层各备选发包模式的决策数据。计算结果显示,EPC总承包模式是最优的选择,DBB模式次之。本文通过对发包模式的研究分析以及层次分析法的运用,探索并构建了一套适合于LNG储罐工程发包模式选择的方法,具有较好的实用价值和研究意义。
[Abstract]:After more than 10 years of development, the domestic LNG industry has built 32 large LNG storage tanks, and it is expected that the number of LNG storage tanks will continue to increase by a large margin in the future. With the change of project characteristics and the improvement of owners' demands and expectations, how to scientifically select a suitable contracting mode for the project will have an important impact on the maintenance of owners' interests. Based on the existing contracting modes of various projects, this paper studies and analyzes the contracting modes suitable for large LNG cryogenic storage tank projects by using the Analytic hierarchy process (AHP). First of all, by comparing the domestic and foreign LNG storage tank project contracting mode and domestic widely used contracting mode, and combining with the current situation of the owner's capacity. Four items of DBB mode, EPC general contracting mode, CM model and EP C model, are determined as the alternative for analysis and research. Secondly, through literature research, expert consultation and judgment, The first grade index of five criterion layer and the second grade index of 14 sub-criterion layer were determined, and the model of the model selection for large LNG storage tank project was constructed. Finally, a questionnaire is designed based on hierarchical structure model, and a questionnaire is sent to selected experts to obtain the basic data of judgment matrix. The weight of five criterion layers and 14 sub-criteria layers are calculated by software analysis. Furthermore, the decision data of each alternative contracting mode are calculated. The results show that EPC general contracting mode is the best choice. Through the research and analysis of the contracting mode and the application of AHP, this paper explores and constructs a set of suitable methods for the selection of the contracting mode of LNG storage tank project, which has good practical value and research significance.
