Resource Redistribution under Lack of Information: Short-Term Recovery after Large Scale Disasters

TL;DR

This paper proposes a resource redistribution mechanism for disaster recovery that remains effective despite delays or incompleteness of information, ensuring efficient short-term recovery of socio-technological systems after large-scale disasters.

Contribution

It introduces a resource redistribution mechanism resilient to information delays and incompleteness, enhancing disaster mitigation strategies.

Findings

Duration of resource redistribution is weakly affected by information lack.

Mechanism ensures efficient recovery regardless of affected region's position.

Simulation confirms robustness of the proposed approach.

Abstract

The paper is devoted to the problem of disaster mitigation. It develops an emergent mechanism of resource redistribution aimed at recovering of a socio-technological system affected by a large scale disaster. The basic requirements to the short-term recovery are taken into account in constructing this mechanism. The system at hand consists of many individual units (cities) and the mechanism is based on their cooperative interaction, which makes the resource redistribution efficient regardless of the particular position of affected region. Previously we studied the dynamics of supply process governed by this mechanism when all the information about the system is available and actual from the beginning of the process (V. Lubashevskiy, T. Kanno, K. Furuta, arXiv:1310.0648). In the present paper we analyze the effects of lack of information on the resource delivery rate. Two scenarios of the lack of information are allowed for. The first one is the delay of the information about the city states. The second one is its incompleteness. As a result of simulation, it is demonstrated that the duration of the resource redistribution governed by the developed mechanism is weakly affected by the lack of information.
