【摘要】：自我國首條城市軌道交通開通以來，到目前已經(jīng)有十多個城市建成近500km的軌道交通運營線路。面對城市軌道交通高速的發(fā)展，安全是軌道交通的重中之重，對軌道交通安全狀況進行評價有著積極的作用。軌道交通企業(yè)在資源相對匱乏和不平衡的狀況下，從投入和產(chǎn)出的角度進行安全效率的研究，不但能夠了解軌道交通安全所處的階段，還能夠明確怎樣分配與利用軌道交通的資源。這樣的評價研究對軌道安全有一定的理論和現(xiàn)實意義。 本文采用了數(shù)據(jù)包絡(luò)分析方法（DEA），且根據(jù)經(jīng)濟學(xué)基本理論來對軌道交通安全效率進評價。數(shù)據(jù)包絡(luò)分析方法是由著名的運籌學(xué)家查恩斯等科學(xué)家在1978年提出的，它應(yīng)用于具有多個投入與產(chǎn)出的復(fù)雜系統(tǒng)，根據(jù)多指標(biāo)投入與產(chǎn)出對相同類型的決策單元進行相對效率的評價。城市軌道交通屬于是一個復(fù)雜的生產(chǎn)系統(tǒng)，具有多項投入和多項產(chǎn)出的特點，數(shù)據(jù)包絡(luò)分析方法應(yīng)用到城市軌道交通的評價當(dāng)中，在保證評價的科學(xué)性和在客觀性的同時，不僅僅可以得到投出和產(chǎn)出的相對效率，而且也能夠得到?jīng)]有達到最優(yōu)效率的原因和投入與產(chǎn)出需要調(diào)整的量。 本文通過介紹城市軌道交通安全理論的基礎(chǔ)上，確定數(shù)據(jù)包絡(luò)適合于城市軌道交通安全效率的評價研究。分析了DEA評價方法的原理和思路，對運用在軌道安全的適用性進行了研究。在對城市軌道交通安全效率的分析上，分別從投入主導(dǎo)型和產(chǎn)出主導(dǎo)型上分別進行了綜合技術(shù)效率，，純技術(shù)效率和規(guī)模效率的分析。在對軌道安全理論和數(shù)據(jù)包絡(luò)的研究基礎(chǔ)上，遵循建立指標(biāo)的原則形成評價指標(biāo)體系。同時也建立了評價軌道安全效率的DEA模型：測量綜合技術(shù)效率的C2R與C2GS2模型，并且通過Matalb數(shù)學(xué)軟件的對模型編程求解。并選取了廣州城市軌道交通9年間的安全為決策單元并進行了相關(guān)評價研究，根據(jù)評價的結(jié)果，對非DEA有效的決策單元進行改進，并提出相應(yīng)的改進對策。 本論文的研究表明。DEA方法可以作為評價軌道交通安全的方法。軌道交通的決策者可以通過利用DEA方法對其安全進行評估，使資源得到充分的利用，改進安全的規(guī)章制度，達到提高安全的效率這個目標(biāo)。
[Abstract]:Since the opening of the first urban rail transit in China, more than ten cities have built rail transit lines near 500km. In the face of the rapid development of urban rail transit, safety is the most important part of rail transit, and it plays an active role in evaluating the safety situation of rail transit. Under the condition of relative scarcity and imbalance of resources, the research on safety efficiency of rail transit enterprises from the angle of input and output can not only understand the stage of rail transit safety, It is also clear how to allocate and utilize the resources of rail transit. This kind of evaluation research has certain theoretical and practical significance to track safety. In this paper, the method of data envelopment analysis (DEA),) is used to evaluate the safety efficiency of rail transit according to the basic theory of economics. The method of data Envelopment Analysis (DEA) was proposed in 1978 by scientists such as renowned operational research scientist Charles Jones. It is applied to complex systems with multiple inputs and outputs. The relative efficiency of the same type of decision making unit is evaluated according to the multiple index input and output. Urban rail transit is a complex production system with the characteristics of multiple inputs and outputs. Data envelopment analysis method is applied to the evaluation of urban rail transit, which ensures the scientific and objective evaluation at the same time. Not only can the relative efficiency of input and output be obtained, but also the reasons why the optimal efficiency is not reached and the amount of input and output need to be adjusted can also be obtained. On the basis of introducing the theory of urban rail transit safety, this paper determines that the data envelope is suitable for the evaluation of urban rail transit safety efficiency. The principle and train of thought of DEA evaluation method are analyzed, and the applicability of applying it to track safety is studied. In the analysis of the safety efficiency of urban rail transit, the comprehensive technical efficiency, pure technical efficiency and scale efficiency are analyzed respectively from the input-oriented and output-oriented. On the basis of studying the theory of track safety and data envelope, the evaluation index system is formed according to the principle of establishing indicators. At the same time, the DEA model for evaluating the track safety efficiency is established: C2R and C2GS2 models for measuring the comprehensive technical efficiency, and the model is solved by programming the Matalb mathematical software. The safety of Guangzhou urban rail transit for 9 years is selected as the decision-making unit and the relevant evaluation research is carried out. According to the evaluation results, the non-DEA effective decision-making unit is improved, and the corresponding improvement countermeasures are put forward. The research in this paper shows that the DEA method can be used to evaluate the safety of rail transit. The decision makers of rail transit can evaluate their safety by using DEA method, make full use of resources, improve safety rules and regulations, and achieve the goal of improving safety efficiency.
