【摘要】：鐵路選線是鐵路建設(shè)的重要組成部分,線路方案比選是鐵路設(shè)計中一項建設(shè)性極強(qiáng)的工作,線路方案選擇正確與否,直接關(guān)系到能否滿足國家政治、經(jīng)濟(jì)和國防對本線路的要求,并且影響到線路設(shè)計的質(zhì)量、工程造價、施工條件和運(yùn)營效果。因此這項工作必須深入實際,根據(jù)不同設(shè)計階段,做好調(diào)查研究,充分收集資料,有系統(tǒng)有計劃地進(jìn)行全面比選。 本文旨在運(yùn)用模糊重心理論進(jìn)行鐵路設(shè)計方案比選,建立線路方案比選系統(tǒng)。將模糊重心理論的方法與線路方案比選結(jié)合。論文首先通過對國內(nèi)鐵路選線的研究,歸納總結(jié)目前存在的問題,提出本文的研究意義和研究內(nèi)容。其次,指出了方案評價的原則和意義,并將系統(tǒng)劃分為技術(shù)、經(jīng)濟(jì)、環(huán)境、社會四個指標(biāo),并建立了系統(tǒng)總體結(jié)構(gòu)圖,對四項指標(biāo)分別進(jìn)行了詳盡的闡述。第三,文章就現(xiàn)有的綜合評價方法進(jìn)行了探討和分析,選擇應(yīng)用廣泛的模糊綜合評價方法作為鐵路線路方案比選的理論基礎(chǔ),其中,重點(diǎn)介紹了本文采用的模糊重心理論的方法。第四,論文在介紹線路方案比選的基礎(chǔ)知識后,對系統(tǒng)的功能設(shè)計和結(jié)構(gòu)設(shè)計進(jìn)行了綜合分析,建立了結(jié)構(gòu)功能設(shè)計圖,并完成了建模。第五,本文引入工程實例對系統(tǒng)進(jìn)行驗證和檢測。用線路方案比選系統(tǒng)在兩個備選方案中選出最佳方案。通過對工程實例的驗證,證明了系統(tǒng)功能具有一定的實用性。 本系統(tǒng)基于面向?qū)ο蟮拈_發(fā)方法,以Visual Studio2003作為系統(tǒng)的開發(fā)平臺,應(yīng)用Visual Basic作為系統(tǒng)的開發(fā)語言,實現(xiàn)了數(shù)據(jù)直接輸入與調(diào)用數(shù)據(jù)文件兩個功能,計算結(jié)果準(zhǔn)確,可視化界面較人性化,效率較高。 鐵路線路方案比選系統(tǒng)的開發(fā),是一個龐大的系統(tǒng)工程,也是一個循序漸進(jìn)的過程,既需要扎實的理論基礎(chǔ),又要有深厚的計算機(jī)編程功底。展望線路方案比選的未來發(fā)展,建立智能化的系統(tǒng)已成為不可阻擋的歷史潮流。
[Abstract]:Railway route selection is an important part of railway construction, and line scheme comparison and selection is a constructive and extremely strong work in railway design. Whether the railway plan is correct or not is directly related to whether or not to meet the national politics. The requirements of economy and national defense for this line will affect the quality of the line design, project cost, construction conditions and operation results. Therefore, this work must go deep into the actual situation, according to the different design stages, do a good job of investigation and study, and collect sufficient data. A systematic and planned overall selection. The purpose of this paper is to use the theory of fuzzy gravity center to compare and select railway design schemes, and to set up a system for comparing and selecting railway line schemes. The method of fuzzy gravity center theory is combined with the selection of line schemes. Firstly, through the research on the selection of railway lines in China, This paper summarizes the existing problems, puts forward the research significance and research content of this paper. Secondly, it points out the principles and significance of program evaluation, and divides the system into four indicators: technology, economy, environment and society. The overall structure diagram of the system is established, and the four indexes are elaborated in detail. Thirdly, the article discusses and analyzes the existing comprehensive evaluation methods. The widely used fuzzy comprehensive evaluation method is chosen as the theoretical basis of railway line scheme comparison and selection. Among them, the method of fuzzy gravity center theory adopted in this paper is introduced emphatically. 4th, after introducing the basic knowledge of route scheme comparison and selection, The function design and structure design of the system are analyzed synthetically, the structure function design diagram is established, and the modeling is completed. 5th, In this paper, an engineering example is introduced to verify and detect the system. The optimal scheme is selected between two alternative schemes by comparing the circuit scheme with the system. Through the verification of engineering examples, it is proved that the function of the system has certain practicability. Based on the object-oriented development method, the system uses Visual Studio2003 as the development platform and Visual Basic as the development language of the system. The system realizes the functions of direct data input and data file transfer, and the calculation results are accurate. The visual interface is more humanized and more efficient. The development of railway line comparison and selection system is a huge system engineering and a gradual process. It needs not only a solid theoretical foundation, but also a solid foundation of computer programming. The establishment of intelligent systems has become an irresistible historical trend.
