【摘要】：我國經(jīng)過長期大規(guī)模的交通基礎(chǔ)設(shè)施建設(shè),建成了一大批不同條件下的工程項目并為在各種復(fù)雜多變的條件下開展線路設(shè)計工作積累了豐富的經(jīng)驗。目前不少研究成果通過挖掘線路工程案例數(shù)據(jù),總結(jié)設(shè)計經(jīng)驗,將多學(xué)科交叉的思想引入線路設(shè)計中,探索出了諸多線路設(shè)計的新理論和新方法。針對線路設(shè)計發(fā)展需要,本文將基于案例的推理技術(shù)(Case-based reasoning,CBR)引入線路設(shè)計工作,并結(jié)合線路特征對案例表達(dá)進(jìn)行了一定的探索。研究主要目的是為線路繼承式經(jīng)驗設(shè)計提供新理論與方法,解決線路案例在運營中暴露出的線路設(shè)計缺陷表達(dá)反饋不明確問題,適應(yīng)云計算和大數(shù)據(jù)的興起對于線路設(shè)計數(shù)字化、智能化與多學(xué)科交叉的變革要求。為實現(xiàn)上述目標(biāo)本文針對線路案例在案例推理技術(shù)中的關(guān)鍵步驟——案例表達(dá),研究了不同線路案例的特征屬性,構(gòu)建了案例要素集,建立了案例表示模塊并在建立理論和實現(xiàn)方法上做了深入探索和研究,主要研究內(nèi)容和成果如下:(1)研究案例推理的主要理論,探究其適用于線路設(shè)計工作的可行性,結(jié)合案例推理的基本原則和方法,進(jìn)行案例推理系統(tǒng)的優(yōu)勢與劣勢分析。(2)將不同環(huán)境條件下的線路案例作為后續(xù)項目參考目標(biāo),從多方面多角度全面展示案例特征。將線路案例特征屬性按照要素分類,依照知識表達(dá)原理建立要素集。(3)將要素集中主要數(shù)據(jù)依照類型分類,探究案例庫系統(tǒng)構(gòu)建主要的技術(shù)及實現(xiàn)方式。利用關(guān)系數(shù)據(jù)庫技術(shù)和地理信息系統(tǒng)有關(guān)技術(shù)的支持,將線路案例和案例推理方法相結(jié)合,完成了案例表示模塊的建立,實現(xiàn)了案例的輸入和展示。案例表達(dá)模塊建立方法的研究可為設(shè)計工作提供有效的案例參考,有效解決運營中設(shè)計缺陷反饋表達(dá)的問題,同時符合數(shù)據(jù)挖掘和學(xué)科交叉的要求,豐富了線路設(shè)計的優(yōu)化手段,為進(jìn)一步研究完善線路工程案例推理系統(tǒng),乃至為推動案例推理在線路設(shè)計的廣泛使用有一定的推動作用。
[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.
