Plan Management And Resource Allocation Optimization On Railway Emergency Management

Railway emergency management has been given wide attention because of frequent railway emergencies, which imply that there are many weaknesses in the construction of the emergency management system and its implementation. Perfect and effective railway emergency management system is the inevitable requirement for rail transport safety. This paper studied the framework of railway emergency management system and the railway emergency plan and emergency resource which impact the efficiency of the railway emergency rescue directly. The main contents are concluded as follows:(1) Construction the framework of railway emergency management system. The term "railway emergency" and "railway emergency management" are defined and analyzed. Railway incidents are motivated by the four factors of human, environmental, equipment, and management, based on which a hierarchical classification risk matrix of railway emergency was put forward. According to the situation, a framework of railway emergency management system was built, which combined macro-middle-micro-scale levels and five aspects of law, system, mechanism, plans, and security system.(2) Relative theories of railway emergency plan. The definition of "railway emergency plan" and "railway emergency plan management" were given. Based on the situation and existing problems in railway emergency plans management, its grade and classification system was advanced, building the relationship among three-level management organization (Ministry of Railways, railway bureau, station and depot), plan type (comprehensive plans, special plans, department plans) and emergency type (natural disasters, accident disaster, public health, social security). Then the concept and model of lifecycle management of railway emergency plan was brought forward and its flow chart was depicted. And the process of drawing out, examination and approval, drilling and exercise, and revision in railway emergency plan are elaborated, All of this made the standards and steps of railway emergency plan management perfect and normative. Finally, the evaluate methods were proposed from form and elements of plan.(3) Railway emergency service facilities location optimization based on interval numbers. Considering the distance between emergency points as interval numbers, the paper built three models of single-point, multi-point and preferred location using minimum risk path. Absolute central point and genetic algorithm were adopted to resolve these problems and examples were presented which indicated the models and algorithms validate(4) Static and dynamic optimization allocation of railway emergency resource. Considering the uncertainty of emergency type and emergency resource demand, taking the maximum of loss reduction as a target, a static allocation model based on utility function was modeled and solved by Monte Carlo. On command of dynamic and fare distribution, a dynamic allocation model based on non-cooperative game theory was built and solved using Nash Equilibrium method.(5) Scheduling method of railway emergency resource. The scheduling models of single-point single-resource, single-point multi-resource and multi-point multi-resource were built, which considering different constraint condition and goals, and solved in different methods.(6) Combined with the theories and methods proposed in the paper, the emergency rescue command system for Qinghai-Tibet railway was developed. Its framework and functions were elaborated. The system provided a set of solutions for the railway emergency resource allocation optimation.
