System resilience enhancement through modularization for large scale cyber systems

It has become increasingly evident that large scale cyber systems can be brittle and may exhibit unpredictable behavior when faced with unexpected disturbances. Even weak and innocuous disturbances can bring down the system inoperative and may introduce catastrophic disasters to the society. The goal of this research is to provide effective mechanisms to enhance the resilience of large scale cyber systems. Process interactions will be modeled and the relationship between interaction and system resilience will be analyzed. The effectiveness of modularization on resilience enhancement will be illustrated. A dynamic programming algorithm based solution will be developed to provide a solution to enhance system resilience through system modularization.
