【摘要】：随着我国对水资源利用的大力开发,一些大型水利工程不断开工建设,对缓解电力紧张、防洪排涝起到重要作用。工程建设项目的投资加大,建设周期加长,受外部环境的影响加大,使得工程项目管理变得更加复杂。如何在计划工期内以合理的质量标准和工程造价完成项目,实现项目价值最大化是水利工程项目管理的重要内容。本文从工程项目整体角度出发,以水利工程建设期的工期、成本和质量三大目标的均衡优化及决策为研究对象,提出了三大目标均衡优化的模型和决策方法,并付诸于工程项目实践,研究成果对提升我国水利工程建设期的目标管理理论和技术水平具有非常重要的意义。本文在国家自然科学基金项目(51379192)资助下,主要工作和研究成果如下:(1)提出了水利工程建设期质量-工期分段函数关系式和质量-工期-成本拟合函数关系式,构建了水利工程建设期模糊多模式工期-成本-质量综合均衡优化模型,解决了模糊不确定环境中多种作业实施模式下的水利工程建设期工期-成本-质量综合优化问题。算例优化结果验证了模型的合理性和有效性,并将模型应用到混凝土面板堆石坝工程上,可为工程项目的项目调度和目标控制提供技术支持。(2)提出了一种基于遗传免疫算子的骨干微粒群算法对水利工程建设期模糊多模式工期-成本-质量均衡优化模型进行求解,解决了骨干微粒群算法容易陷入局部最优和多样性较差的问题。通过对多目标标准测试函数的仿真测试,验证了算法具有较好的收敛性和分布性。并将改进算法应用到混凝土面板堆石坝工程工期-成本-质量综合优化模型求解中,收到了良好效果,体现了改进算法的计算优势。(3)提出了一种基于加权广义马氏距离的TOPSIS方法对水利工程建设期工期-成本-质量均衡优化结果进行决策优选,解决了传统TOPSIS方法中决策结果受属性指标量纲影响大、未考虑属性指标间的相关性、协方差矩阵不可逆的问题。实例表明,基于加权广义马氏距离的TOPSIS方法优选出的结果符合实际情况,验证了改进方法的合理有效性,为水利工程建设项目决策方案的评价优选提供一种更好的智能决策工具。(4)以河口村水库工程为例,对本文提出的水利工程建设期工期-成本-质量均衡优化及决策的研究成果进行了应用研究,决策结果可为河口村水库工程管理者制定资源配置计划和项目调度计划,对工程进行系统调控提供技术支撑。河口村水库工程的实际应用是本文理论研究成果指导实践的新尝试,同时也验证了本文提出的水利工程建设期工期-成本-质量均衡优化模型和多属性决策方法具有合理性和一定的可操作性。
[Abstract]:With the development of water resources utilization in China, some large water conservancy projects continue to be built, which plays an important role in alleviating the power shortage and flood control and drainage. The construction project management becomes more complicated because of the increase of the investment, the longer construction cycle and the greater influence of the external environment. How to complete the project with reasonable quality standard and project cost within the planned period and maximize the project value is an important content of water conservancy project management. From the point of view of the whole project, this paper puts forward the model and decision method of equilibrium optimization of water conservancy project construction period, taking the balance optimization and decision of the construction period, cost and quality of water conservancy project as the research object. The research results are of great significance to improve the management theory and technology level of water conservancy projects in China. Supported by the National Natural Science Foundation of China 513791922, the main work and research results are as follows: 1) the relationship between quality and construction period and the fit function between quality and cost in the construction period of water conservancy projects are put forward in this paper. In this paper, a fuzzy multi-mode comprehensive optimization model of duration, cost and quality in the construction period of water conservancy project is constructed, which solves the problem of comprehensive optimization of construction period, cost and quality of water conservancy project under multiple operation implementation modes in fuzzy uncertain environment. The optimization results of an example verify the rationality and validity of the model, and the model is applied to the concrete face rockfill dam project. This paper provides technical support for project scheduling and target control of engineering projects. (2) A backbone particle swarm optimization algorithm based on genetic immune operator is proposed to solve the fuzzy multi-mode time-cost quality equilibrium optimization model in the construction period of water conservancy projects. It solves the problem that backbone particle swarm optimization is easy to fall into local optimum and diversity is poor. The convergence and distribution of the algorithm are verified by the simulation of multi-objective standard test function. The improved algorithm is applied to solve the comprehensive optimization model of concrete-faced rockfill dam with time-cost and quality, and good results are obtained. This paper presents a TOPSIS method based on weighted generalized Markov distance to optimize the optimization results of construction period, cost and quality of water conservancy projects. In the traditional TOPSIS method, the decision results are greatly affected by the dimension of the attribute index, the correlation between the attribute indexes is not considered, and the covariance matrix is irreversible. An example shows that the TOPSIS method based on weighted generalized Markov distance is suitable for the practical situation, and the validity of the improved method is verified. To provide a better intelligent decision tool for the evaluation and selection of water conservancy project construction project, taking the Hekou village reservoir project as an example, In this paper, the research results of optimization and decision making of the balance between duration, cost and quality in the construction period of water conservancy project are studied. The decision result can make the resource allocation plan and the project dispatching plan for the project manager of Hekou village reservoir. Provide technical support for systematic control of the project. The practical application of Hekou Village Reservoir Project is a new attempt to guide the practice of the theoretical research achievements in this paper. At the same time, it is verified that the proposed optimization model and multi-attribute decision making method of water conservancy project construction period are reasonable and feasible.
