They play a deterministic role in supporting societal mobility, economy, and state strategic defence. Current earthquake response practice demonstrates that the railway is better monitored and has a better potential for fast recovery, and as a rule may have less damage compared to other means of transportation. Therefore, railroads might be returned to operational state quicker. Railways in general – especially in regions where the road systems are less developed– can support disaster management very well. The overall objective of this thesis is to developing models and methodology for active adaptive response to earthquake damage to railways. By more detailed definition of this overall objectives the following tasks had been identified: (i) study the role of railway in disaster response, (ii) analysis of the railway damage and recovery processes, (iii) investigation and developing the required models and (iv) creating and testing the concept of active adaptive response management methodology focused on the fast recovery of railroads in accordance with the operational levels. The general model of response is a combination of (i) a probabilistic model of railway system damage caused by earthquake, (ii) a Markov model of damage and recovery, (iii) a probabilistic model of aftershocks, (iv) a statistical model of secondary effects, (v) impact models of management supporting actions and (vi) response process models. The concept validation is based on the simulations. The described response management is recommended to be implemented into the general disaster management procedures. The major results of the study can be summarized in the following: the role of railway systems in the (earthquake) response management should be considerably improved, because it is underestimated today its damage is moderate and it can be quickly recovered to the operational (usable) level; the extensive literature survey performed and analysed models resulted to definition a general indicator of railway damage as relative unusable track length (like a parameter of the lost capacity) and developing a series of models describing the railway damage – recovery processes; creating an active adaptive response to earthquake damage to railways based on recurring cycles of the zero + six + one steps, including semi empirical situation awareness – evaluation – decision making between each steps, that is supported by the discussed sub-models employing different theoretical, semi-practical calculations and simulations; the introduced methodology had been applied to simulations and concept validation tests including use of available historical data about railway damages caused by earthquakes and fast recovery, using the developed sub-models and followed experts’ recommendations advising possible decisions in different simulated situations. The developed methodology will significantly reduce the number of deaths in the earthquake zone, since the dynamics of the number of deaths caused by earthquakes depends directly on the scale and pace of the rescue operations. Key words: earthquake, disaster/emergency management, railway systems, railway damage, response and recovery modelling. 2 Sergey Kinzhikeyev Modeling recovery of railway system after earthquakes Contents Abstract ................................................................................................................................................... 2 Introduction ............................................................................................................................................. 9 1.
