【摘要】：城市供水系統(tǒng)是城市形成的必要基礎(chǔ)，，是城市形成和發(fā)展的先決條件之一。城市供水系統(tǒng)安全與否，關(guān)系到城市的興衰。近年來，由于環(huán)境污染以及城市管網(wǎng)的老化破壞，城市供水系統(tǒng)的安全性正在面臨前所未有的挑戰(zhàn)。因此，對城市供水系統(tǒng)進行安全評價，對于城市供水系統(tǒng)的管理建設(shè)將具有非常重要的意義。 本文將供水系統(tǒng)分為水源地與供水管網(wǎng)兩大部分進行評價。深入分析供水系統(tǒng)安全評價的研究現(xiàn)狀及發(fā)展方向，簡要介紹安全評價的理論知識，利用故障樹分析法全面分析影響供水系統(tǒng)安全的因素，進而建立安全評價指標體系，在指標體系的基礎(chǔ)上，建立安全評價等級表。通過查閱大量資料，不斷嘗試，將一些對層次分析法比較完善的改進有機的結(jié)合在一起，并且和相關(guān)性關(guān)系計算組成一個新的改進的層次分析法(IAHP)。應用SPSS軟件對評價指標的相關(guān)性進行分析，采用三標度法間接建立判斷矩陣，采用求解擬優(yōu)化一致性矩陣的方式提高矩陣的一致性，進而確定權(quán)重，并利用MATLAB7.1編制程序計算，將應用傳統(tǒng)的與改進的層次分析法進行對比分析。在此基礎(chǔ)上，建立以模糊模式識別模型和模糊綜合評判相結(jié)合的多層次多級復雜系統(tǒng)模糊評價模型，依靠該模型，并借助EXCEL的矩陣運算功能提高運算精確性，最后計算出安全評價等級。 依托“基于節(jié)能減碳的供水網(wǎng)絡(luò)多目標多工況智能優(yōu)化技術(shù)研究”和“黃河中下游地區(qū)供水管網(wǎng)安全保障國家重大專項---基于供水安全的城市供水管網(wǎng)的優(yōu)化改擴建技術(shù)”兩大課題，以東營市水源地和青島市區(qū)管網(wǎng)為研究區(qū)域，依靠多層次多級復雜系統(tǒng)模糊評價模型，分別計算水源地及供水管網(wǎng)的安全等級。根據(jù)計算結(jié)果，分析系統(tǒng)運行的問題，并對存在問題提出改進建議。
[Abstract]:Urban water supply system is the necessary foundation of urban formation and one of the prerequisites for urban formation and development. Whether the urban water supply system is safe or not is related to the rise and fall of the city. In recent years, the safety of urban water supply system is facing unprecedented challenges due to environmental pollution and aging damage of urban pipe network. Therefore, the safety evaluation of urban water supply system will be of great significance to the management and construction of urban water supply system. In this paper, the water supply system is divided into two parts: water source and water distribution network. This paper deeply analyzes the research status and development direction of water supply system safety evaluation, briefly introduces the theoretical knowledge of safety evaluation, analyzes the factors affecting water supply system safety by using fault tree analysis method, and then establishes a safety evaluation index system. Based on the index system, the safety evaluation level table is established. By consulting a large amount of data, we try to combine some perfect improvements of AHP, and form a new improved Analytic hierarchy process (IAHP) with the calculation of correlation relationship. The correlation of evaluation index is analyzed by SPSS software, the judgment matrix is established indirectly by using three-scale method, the consistency of matrix is improved by solving the quasi-optimization consistency matrix, and the weight is determined, and the calculation program is compiled by MATLAB 7.1. The traditional analytic hierarchy process and the improved analytic hierarchy process are compared and analyzed. On this basis, the fuzzy evaluation model of multi-level and multi-level complex system based on the combination of fuzzy pattern recognition model and fuzzy comprehensive evaluation is established. The model is relied on and the calculation accuracy is improved by the matrix operation function of excel. Finally, the grade of safety evaluation is calculated. Research on Multi-objective and Multi-condition Intelligent Optimization Technology of Water supply Network based on Energy Saving and carbon reduction and National Major Project of Water supply Network Safety guarantee in the Middle and Lower reaches of Yellow River: optimization and Reform of Urban Water supply Network based on Water supply Security Two major topics of expansion technology, Based on the fuzzy evaluation model of multi-level and multi-level complex system, the safety grade of water source and water supply network are calculated by taking Dongying water source area and Qingdao urban pipeline network as the research area. According to the calculation results, the problems of system operation are analyzed, and suggestions for improvement are put forward.
