heal.abstract Although not at the forefront of emergency management rationale, in cases of catastrophes, transportation networks prove their role as vital lifelines, ensuring network connectivity and providing the necessary, underlying ways for the execution of a series of emergency operations. At the same time, transportation networks are themselves vulnerable to structural and functional degradation, which, combined with the stochasticity involved in the travelers' behavior and the diverse needs arising under emergency conditions, mount the pressure for the need of effective network management; this will, most probably than not, require a re-structuring of network functioning, often in the form of network re-configuration, along with the employment of other operational strategies. In this context, the development of appropriate management tools that can account for the network's operational state and the individuals' behavioral aspects and optimally re-structure them to the benefit of overall network functionality are of significant practical importance. In such settings, these tools can help facilitate the related emergency operations and provide critical added value to the whole disaster management process. In this context, the present thesis endeavors to advance the state-of-the-art in disaster management by providing a framework that supports and promotes the enhancement of network functionality in an integrated manner. The thesis distances itself from the consideration of specific network operations and examines network functioning from a wider perspective, that of generalized network management. In order to do so, the framework explicitly considers the operational state of the network and users' behavioral patterns and attempts a system re-organization on the basis of defined objectives; this is achieved through the use of appropriate strategies, the development of a multi-aspect performance measure, the formulation of suitable hypotheses regarding route construction and route choice and the selection of an appropriate analysis concept. The dissertation ultimately provides a sound conceptual and mathematical framework for efficiently handling the various needs arising in the period following a catastrophe. The framework can be used as a planning tool by transportation professionals and stakeholders and adds a higher degree of realism in the decision-making process by explicitly accounting for some of the stochasticities that are either way present in transportation management, but possibly exacerbated in a post-disaster setting. en
