【摘要】：建设工程项目的生产规模大、资源消耗多、生产和使用周期长以及管理任务重等特点决定了工程项目实施过程中存在着大量导致工程变更的不确定因素,工程变更频繁发生;而工程变更也对项目的投资、进度、质量三大管理目标的实现形成了巨大阻碍。综合工程变更发生的高频性和变更对项目管理造成的不可小觑的影响,工程变更管理势必成为建设工程项目管理的一项重要内容,研究对工程变更的管理和控制具有重要意义。本文站在业主方的角度进行研究,首先通过对工程变更管理相关背景资料的分析,总结出研究的意义和目的,然后通过对大量国内外文献资料的分析,总结出对工程变更管理研究的三个不足之处。接着对工程变更的定义、分类、表现形式及其影响等相关理论作一个概述,为接下来的研究奠定理论基础。再接着对这三个问题分别提出实用的分类解决方法:第一,确定了一套变更风险流程管理的方法,分为设定目标、风险识别、风险评估、风险分配、风险控制、风险管理后评估六个步骤来进行工程变更风险的有效控制;第二,在做好变更风险控制的前提下,采用定性与定量相结合的方法,构建群决策REM相对熵集结模型来进行变更方案优选,解决了变更方案选择随意性大的问题;第三,详尽明确了三类变更综合单价的确定方法并建立了识别变更综合单价中不平衡报价的数学模型,解决了变更综合单价确定无定则的问题;最后进行研究总结,指出本文研究的不足并对今后变更管理的研究作出展望。本文通过对工程变更管理中现存的三个问题提出实用的解决方法,为变更管理提供重要的思路,对顺利实现项目管理的三大目标具有重大的现实意义。
[Abstract]:The characteristics of large production scale, large consumption of resources, long production and service cycle and heavy management tasks determine that there are a large number of uncertain factors leading to engineering changes in the process of implementation of construction projects, and engineering changes occur frequently. But the project change also forms the huge obstacle to the project investment, the progress, the quality three management goal realization. The high frequency of the comprehensive engineering change and the influence of the change on the project management can not be underestimated. The engineering change management is bound to become an important content of the construction project management, and the research is of great significance to the management and control of the engineering change. In this paper, from the perspective of the owner, the author summarizes the significance and purpose of the research through the analysis of the background information of engineering change management, and then through the analysis of a large number of domestic and foreign literature. Three deficiencies of the research on project change management are summarized. Then the definition, classification, manifestation and influence of engineering change are summarized, which lays a theoretical foundation for the following research. Then put forward the practical classification solutions to these three problems: first, determine a set of change risk process management methods, including target setting, risk identification, risk assessment, risk allocation, risk control, After risk management, six steps are used to effectively control the risk of engineering change. Secondly, the qualitative and quantitative methods are used to control the risk of engineering change. The REM relative entropy aggregation model is constructed to optimize the selection of change schemes, which solves the problem of randomness in the selection of change schemes. Thirdly, In this paper, the methods of determining three kinds of variable integrated unit price are clarified in detail, and the mathematical model of identifying unbalanced quotation in changing comprehensive unit price is established, which solves the problem of determining the unfixed price of changing comprehensive unit price. This paper points out the deficiency of this paper and looks forward to the study of change management in the future. This paper puts forward practical solutions to the three existing problems in project change management, which provides important ideas for change management, and has great practical significance for the smooth realization of the three goals of project management.
