Emergency plan modeling is the foundation of the work for digitizing emergency plans. On the basis of analyzing the content and structure of the existing urban rail transit emergency plans, a formalization method for emergency plans based on ontology is put forward. The core terms of emergency plans are extracted and classified. The relationships between various concepts are concluded. Combined with related concepts of ontology five meta-words, the ontology model of emergency plans is constructed. The emergency plan system from a subway company is presented as a real world case to establish the semantic model, providing the feasibility of the method proposed.

Emergency plan is a project document to guide and deal with public emergency events, and also is the core of emergency management. Nowadays, most emergency plans in China exist in non-semantic form and are difficult to play roles effectively. Ontology is an important method to describe semantic model. Therefore, in this paper, emergency plan ontology model is constructed by ontology technology of semantic Web and Web Ontology Language OWL, which formally describes the conceptions of emergency plan and the relations between them. Finally, the model is used in ontology-based semantic retrieval system, and improves the retrieval recall and precision.

Fire emergency response of urban rail transit is a complex multiattribute risk decision-making problem. In emergency response analysis, it is necessary to consider the psychological behaviors of decision-makers such as reference dependence, loss aversion, and judge distortion. Applying different emergency plans can intervene the development and evolution of urban rail emergency fire and may even result in different levels of casualties and property losses. For this situation, this paper proposes an emergency response decision-making method based on prospect theory. First, according to the prospect theory, this paper quantitatively describes the comprehensive psychological perception of decision-makers for casualties and property losses in different situations. Then, the psychological perception of decision-makers for the important levels of different situations is calculated. Third, according to the situation comprehensive values, situation weights, and the cost inputs of emergency plans, the comprehensive prospect values of each emergency plan are calculated, and the fire emergency plans can be ranked based on comprehensive prospect value. At last, the fire emergency disposal of Tianjin rail transportation line 3 is considered as the background in this paper. The feasibility and effectiveness of the purposed method is illustrated through the case study.

Analyze the sudden failure influence to urban rail transit normal operation, has important significance to grasp the key of failure emergency treatment. This paper take moving block mode for example, first by use of multi-particle traction model, general consider the passenger comfort, safety control and other factors, design the multi-train tracking calculate model. Then according to the different influence to urban rail transit operation, classify the sudden failure into two kinds: sudden train failure and sudden section break off failure, analyze the multi-train movement simulate arithmetic under the two kinds of failure, based on this, design the simulation system’s workflow, build the urban rail transit multi-train movement simulate system under sudden failure. Finally, by analyze the calculate results of two kinds of failure, verified the system’s validity. Simulate urban rail transit multi-train movement process under sudden failure can master the detail instance about failure influence operation, deeply analysis the infect’s diffusion process caused by failure or delay, provide a powerful assist analyze tool to analysis the network’s operation reliability, constitute correlative emergency plan.
