Functional requirements of CPS
multi-control functions (supervision for fault diagnostic and corresponding maintenance requests)
Knowledge base (for capitalization and learning functions)
Inference processes (for decision-making aid and dynamic reconfiguration)
Communication interfaces (with umans but also with different connected components)
Requirements (Horvath)
Develop strategies about how to adapt & enhance the sensing, reasoning and informing operations according to the available dynamic context information in real time
Reasoning engine that is able to apply multiple various mechanisms
strategies: the RE needs & should regulate the necessary actuations for controlling context-dependent sensing & informing
The sensors & the informing terminals should perform the control strategies without significant delay in ordrer to enable a timely completion of the context-dependent sensing and informing actions
Context dependent operations closely depends on each other. Each op has to respond to the requests of other operations
The sensor should provide sufficient information for various reasoning & informing actions of the system
Functions (Horvath)
MF of c-d-s
Adapt the sensing behavior to the dynamic context
Aggregate real-time information from the physical world
Manage context information used for developing control strategies
Interpret the need of information from other cd operations
Develop a control strategy to control the WSN
Translate the control strategy into control signals
MF of c-d-r
Make inference based on the available set of information and perform reasoning according to the dynamically changing context
analyze the situation based on the information aggregated
Select a proper reasoning mechanism according to the context information
Manage the context-information, which is required by the context mechanism
Query information from the sensing components
Generate contents for informing by using the reasoning mechanism
MF of c-d-i
Execute the informing of the stakeholders and adapt the informing actions according to the changes in the context
Manage context information which is required by the reasoning mechanisms
query information from the context-dependent sensing components
Select an informing method for a particular stakeholder based on the strategy and the context information
Construct instructive messages for each particulare stakeholder
Integration mechanisms (Horvath)
Internal integration
Enable the generic kernel to provide context dependent strategies for the target application
External Integration
Establish connection with the distributed sensing and actuating components.
