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 system at hand consists of many individual units (cities) and the mechanism is based on their cooperative interaction, which makes the recovery efficient regardless of the particular position of affected region. Previously we studied the dynamics of recovering 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. Proc. Int. Conf. Sim. Tech. (JSST 2012), p. 493). In the present paper we analyze the effects of lack of information on the recovery rate. The first one is the delay of the information about the city states. The second one is its incompleteness. As one of the main results, it is demonstrated that the duration of recovering process weakly affected by the lack of information.
