Метод композиційного забезпечення функціональної стійкості інформаційної системи на мобільній платформі

Abstract

The paper addresses the problem of ensuring functional resilience of information systems deployed on mobile platforms operating under limited resources and intermittent connectivity. A method of compositional provision of functional resilience is proposed based on forming alternative service compositions and adaptive system reconfiguration according to current resource conditions. An integral indicator of compositional resilience is introduced to evaluate system operability considering service states, resource usage, reconfiguration costs, and communication channel availability. The method enables adaptive operational control and improves survivability of mobile information systems in dynamic environments.
