Query: Contract-based Hierarchical Resilience Management for Cyber-Physical
  Systems   Orchestrated collaborative effort of physical and cyber components to satisfy
given requirements is the central concept behind Cyber-Physical Systems (CPS).
To duly ensure the performance of components, a software-based resilience
manager is a flexible choice to detect and recover from faults quickly.
However, a single resilience manager, placed at the centre of the system to
deal with every fault, suffers from decision-making overburden; and therefore,
is out of the question for distributed large-scale CPS. On the other hand,
prompt detection of failures and efficient recovery from them are challenging
for decentralised resilience managers. In this regard, we present a novel
resilience management framework that utilises the concept of management
hierarchy. System design contracts play a key role in this framework for prompt
fault-detection and recovery. Besides the details of the framework, an Industry
4.0 related test case is presented in this article to provide further insights.
