【摘要】：我国高速铁路的建设和运营里程均位居世界第一,已成为象征国人骄傲的国家名片。相比于普通铁路和高速公路等道路工程,高速铁路施工由于施工难度大、涉及技术高给物资管理带来了新的挑战,物资管理的优劣对工程项目的质量和施工成本有着重要的影响。鉴于此,本文对高速铁路施工项目中的物资管理流程、评价方法、优化方法等展开了研究,分析讨论了高速铁路中的物资管理问题和优化问题。首先,总结了项目施工过程中的物资管理流程,研究了物资管理组织结构、物资计划、物资采办以及重要材料的管理制度和方法,归纳了物资管理对工程施工的影响和现存管理方式的优劣。指出物资管理贯穿于整个项目施工过程,必须加强物资管理的制度建设。其次,从质量控制、成本控制和风险控制三个角度研究了施工项目中的物资管理评价方法,采用模糊评价法对供应商进行了评价,获取了材料价值较高的供应商。结果表明,物资管理的评价应当综合考虑质量控制、成本控制以及风险控制,但模糊评价方法存在受主观因素影响大等不足。然后,提出了改进型差分进化算法作为物资管理的优化算法,并建立了相应的数学模型,使用C++语言编写了优化程序。结果表明,rand-to-best和best-to-rand差分算子结合自适应控制参数后的算法对所有测试函数均有较高的成功率,并且前者能兼顾算法的成功率和计算效率。最后,发展了物资管理优化模型,提出了物资管理优化流程。以沪昆客运专线云南段施工项目中的钢筋采购为例,针对物资管理中的关键环节和供应商的主要属性,开展了物资管理优化分析。结果表明,优化模型能综合权衡采购、运输、仓储和回收等环节中的众多因素,得出保证工程质量和进度并使得总成本最低的物资管理方案。优化的备选供应商数量越多,总成本越低,物资管理评价方法对优化结果的影响越小,大幅减弱了人为主观因素对优化管理的影响。
[Abstract]:The construction and operation mileage of high-speed railway in China ranks first in the world, and has become the national business card that symbolizes the pride of Chinese people. Compared with other road projects, such as ordinary railways and highways, the construction of high-speed railways has brought new challenges to material management because of the difficulty of construction and the high technology involved. The quality of material management has an important impact on the quality and construction cost of the project. In view of this, this paper studies the material management flow, evaluation method and optimization method in the construction project of high-speed railway, and analyzes and discusses the material management problem and optimization problem in high-speed railway. First of all, it summarizes the material management process in the construction process of the project, studies the material management organization structure, the material plan, the material acquisition and the important material management system and the method. The influence of material management on engineering construction and the advantages and disadvantages of existing management methods are summarized. It is pointed out that material management runs through the whole construction process of the project, and the system construction of material management must be strengthened. Secondly, from three aspects of quality control, cost control and risk control, the evaluation method of material management in construction project is studied, and the supplier with high material value is obtained by using fuzzy evaluation method. The results show that quality control, cost control and risk control should be taken into account in the evaluation of material management. Then, the improved differential evolution algorithm is proposed as the optimization algorithm for material management, and the corresponding mathematical model is established, and the optimization program is written in C language. The results show that the algorithm with rand-to-best and best-to-rand difference operator combined with adaptive control parameters has a high success rate for all test functions, and the former can take into account the success rate and computational efficiency of the algorithm. Finally, the optimization model of material management is developed, and the optimization flow of material management is put forward. Taking the steel bar purchasing in the construction project of Yunnan section of Hu-Kun passenger dedicated line as an example, the optimization analysis of material management is carried out in view of the key links in material management and the main attributes of suppliers. The results show that the optimization model can balance many factors in procurement, transportation, storage and recovery, and obtain the material management scheme which can ensure the quality and schedule of the project and make the total cost lowest. The more the number of alternative suppliers is, the lower the total cost is, and the less the impact of material management evaluation method on the optimization results is, which greatly weakens the influence of human subjective factors on the optimization management.
