【摘要】：房地产企业往往对建设工程的开发节奏控制比较严格，一些节点的脱节都可能造成工程延期，而且还可能导致成本的增加以及一些工程质量问题。作者在地产公司工程部实习过程中参与了消防验收、交房等活动，感受到工程部对建设节奏、节点的重视程度，对延期影响因素研究具有一定的价值，，故选延期影响因素作为研究课题。文章针对我国工程项目建设中经常因受到众多因素影响而出现工程延期的现象，且国内对工程延期影响因素的相关研究尚不够深入的情况下，通过分析、评价建设工程项目延期的主要影响因素，并提出相应的防范措施，对确保工程项目的顺利建成并及时发挥其投资效益具有一定理论价值和重要的现实意义。文章综合运用了文献研究法、专家访谈法、问卷调研研究法、定性分析与定量分析相结合方法、实证分析等方法。先是对工程延期相关的研究及理论进行了梳理和回顾，分析了国外关于延期研究的两个主要流派的主要观点并进行了对比，阐述了国内对于延期方面研究主要观点，为得到影响中国建设工程延期影响因素及构建模型做了理论铺垫。接着阐述了文章涉及到的基础理论，即建设工程项目管理的相关理论、建设工程项目进度管理的相关理论等等，通过对这些相关理论的研究为后文分析工程延期影响因素、确定分析方法以及构建评价模型奠定理论基础。根据文献研究法初步确定影响工程延期影响因素的WBS网络图，并结合专家访谈法最终确定了建设工程延期影响因素表，为后面实例分析提供了基础。文章详细介绍了主成分分析法的相关理论及基于主成分分析法评价模型的构建过程，即有效变量的筛选、主成分分析法适用性检验、确定主成分因子的数量、确定主成分因子的荷载分布及主成分因子表达式、主成分因子重新命名及解释；文章结合前面得到的39个延期影响因素，对评价模型进行实例分析，通过评价模型的具体运用最终得到并解释了7个工程延期的主成分因子，即：施工现场管理因子、沟通管理因子、设计管理因子、项目前期准备管理因子、成本管理因子、资源管理因子、质量管理因子。论文根据主成分评价模型得到的引起建设工程项目主要延期因素的7个主成分因子，针对性地提出预防工程延期的措施，文章的研究成果不仅能够完善工程项目管理体系，并且能够为工程项目管理者改善工程项目延期的现状提供较好的参考与借鉴。
[Abstract]:Real estate enterprises often have strict control over the pace of development of construction projects, and the disjointing of some nodes may result in project delays. It may also lead to the increase of cost and some problems of engineering quality. The author participated in the fire control acceptance, house delivery and other activities in the internship process of the engineering department of the real estate company, and felt that the engineering department attached great importance to the construction rhythm and node. It has certain value to the research of delay influencing factors, so we choose delay factors as the research topic. In view of the phenomenon that the project delay often occurs because of the influence of many factors in the construction of the project in our country, and the related research on the influencing factors of the project delay in our country is not deep enough, through the analysis, To evaluate the main factors affecting the delay of construction projects, and to put forward the corresponding preventive measures, It has certain theoretical value and important practical significance to ensure the smooth construction of engineering project and bring its investment benefit into full play in time. The paper synthetically applies literature research method, expert interview method, questionnaire research method, etc. The qualitative analysis combined with quantitative analysis, empirical analysis and other methods. First of all, the related research and theory of project delay are reviewed and reviewed, and the main viewpoints of two main schools of delay research abroad are analyzed and compared. This paper expounds the main viewpoints of the research on delay in China, and makes a theoretical foundation for obtaining the influencing factors and the construction model of the delay of construction projects in China, and then expounds the basic theory involved in the article. That is, the related theories of construction project management, construction project schedule management and so on. This paper establishes the theoretical foundation for determining the analysis method and the construction of evaluation model. According to the literature research method, the paper preliminarily determines the WBS network diagram that affects the factors affecting the delay of the project, and finally determines the table of the influencing factors of the delay of the construction project in combination with the expert interview method. The related theory of principal component analysis and the construction process of evaluation model based on principal component analysis are introduced in detail, that is, the selection of effective variables, the applicability test of principal component analysis. The number of principal component factors, the load distribution of principal component factors, the expression of principal component factors, the renaming and interpretation of principal component factors are determined. Through the concrete application of the evaluation model, seven principal component factors of project delay are obtained and explained, that is, construction site management factor, communication management factor, design management factor, pre-project preparation management factor, cost management factor, etc. Resource management factor, quality management factor. According to the seven principal component factors that cause the main delay factors of the construction project, the paper puts forward the measures to prevent the delay of the project. The research results of the paper can not only perfect the project management system. And can provide better reference and reference for project manager to improve the status quo of project extension.
