Complex equipment system resilience: Composition, measurement and element analysis

This paper analyzes the resilience composition of complex equipment system. By considering the system itself, resources, and the human factor, the resilience is analyzed from three components: structure resilience, resource resilience and strategy resilience. The impact of subsystems and their interrelationships on resilience are analyzed in structure resilience. In resource resilience, consumable and non-consumable resources are distinguished, and their influences on system resilience are analyzed, respectively. In strategy resilience, how people affect system resilience is discussed, and the nature of strategy resilience in resilience process is analyzed. Based on the above analysis, how these three components of resilience perform in actual systems is analyzed, and the three components of system resilience are refined into five specific factors involved in system resilience. Then, an improved resilience measurement method for complex equipment systems is given. In simulation, the five elements of resilience are analyzed and studied, respectively. Through simulation and comprehensive analysis, this paper can give a deeper understanding of the three components of system resilience. The quantitative and qualitative analysis on how to optimize the system under the framework of resilience engineering and the optimization principles of system are provided.
