Methods for Adaptive Resource Availability Management of Geoinformation Systems under Destructive Impacts

Abstract

The complexity of ensuring the availability of geoinformation systems resources is due to the volatile structure of the system, the uncertainty of user tasks and destructive influences. This paper proposes methods that allow to halve the probability of information security risk associated with the disruption of resource availability. The effect is achieved by: 1) preserving the required probability of achieving the activity goal of the identification system, regardless of the strength of disruptive influences; 2) by aggregating the performance of individual physical system elements into virtual pools; and 3) by converting internal user task reserves into performance reserves. The performance of the methods was evaluated using a simulation model developed in MATLAB environment.
