【摘要】：我国经过长期大规模的交通基础设施建设,建成了一大批不同条件下的工程项目并为在各种复杂多变的条件下开展线路设计工作积累了丰富的经验。目前不少研究成果通过挖掘线路工程案例数据,总结设计经验,将多学科交叉的思想引入线路设计中,探索出了诸多线路设计的新理论和新方法。针对线路设计发展需要,本文将基于案例的推理技术(Case-based reasoning,CBR)引入线路设计工作,并结合线路特征对案例表达进行了一定的探索。研究主要目的是为线路继承式经验设计提供新理论与方法,解决线路案例在运营中暴露出的线路设计缺陷表达反馈不明确问题,适应云计算和大数据的兴起对于线路设计数字化、智能化与多学科交叉的变革要求。为实现上述目标本文针对线路案例在案例推理技术中的关键步骤——案例表达,研究了不同线路案例的特征属性,构建了案例要素集,建立了案例表示模块并在建立理论和实现方法上做了深入探索和研究,主要研究内容和成果如下:(1)研究案例推理的主要理论,探究其适用于线路设计工作的可行性,结合案例推理的基本原则和方法,进行案例推理系统的优势与劣势分析。(2)将不同环境条件下的线路案例作为后续项目参考目标,从多方面多角度全面展示案例特征。将线路案例特征属性按照要素分类,依照知识表达原理建立要素集。(3)将要素集中主要数据依照类型分类,探究案例库系统构建主要的技术及实现方式。利用关系数据库技术和地理信息系统有关技术的支持,将线路案例和案例推理方法相结合,完成了案例表示模块的建立,实现了案例的输入和展示。案例表达模块建立方法的研究可为设计工作提供有效的案例参考,有效解决运营中设计缺陷反馈表达的问题,同时符合数据挖掘和学科交叉的要求,丰富了线路设计的优化手段,为进一步研究完善线路工程案例推理系统,乃至为推动案例推理在线路设计的广泛使用有一定的推动作用。
[Abstract]:After a long period of large-scale transportation infrastructure construction in China, a large number of engineering projects under different conditions have been built and rich experience has been accumulated for the development of route design under various complex and changeable conditions. At present, many research achievements introduce the idea of multi-disciplinary crossing into the circuit design by mining the case data of line engineering, sum up the design experience, and explore many new theories and methods of line design. To meet the needs of the development of line design, this paper introduces Case-based reasoning (CBR) technology into line design work, and explores the case representation based on line characteristics. The main purpose of the study is to provide a new theory and method for line inherited experience design, and to solve the problem of unclear feedback of line design defects exposed in line cases. To adapt to the rise of cloud computing and big data, line design digital, intelligent and multidisciplinary intersection of the reform requirements. In order to achieve the above goal, this paper studies the characteristic attributes of different line cases and constructs the case element set, aiming at the key step of line case in case-based reasoning technology-case representation. This paper establishes a case representation module and makes a deep exploration and research on the theory and implementation method. The main research contents and results are as follows: 1) the main theory of case-based reasoning is studied, and the feasibility of its application to the design of the circuit is explored. Combined with the basic principles and methods of Case-Based reasoning (CBR), the advantages and disadvantages of Case-Based reasoning system (CBR) are analyzed. The feature attribute of line case is classified according to elements and the set of elements is established according to the principle of knowledge expression. (3) the main data of element set is classified according to type, and the main technology and implementation of case base system are explored. With the support of relational database technology and geographic information system (GIS) technology, the method of line case and case-based reasoning is combined to complete the establishment of case representation module, and the input and display of cases are realized. The research of case expression module can provide effective case reference for design work, solve the problem of design defect feedback expression effectively in operation, and meet the requirements of data mining and subject intersection. It enriches the optimization methods of line design and promotes the further research and improvement of line engineering case-based reasoning system and even the extensive use of CBR in line design.
