A formal and run-time framework for the adaptation of local behaviours to match a global property

We address the problem of automatically identifying what local properties the agents of a Cyber Physical System have to satisfy to guarantee a global required property φ. To enrich the picture, we consider properties where, besides qualitative requirements on the actions to be performed, we assume a weight associated with them: quantitative properties are specified through a weighted modal-logic. We propose both a formal machinery based on a Quantitative Partial Model Checking function on contexts, and a run-time machinery that algorithmically tries to check if the local behaviours proposed by the agents satisfy φ. The proposed approach can be seen as a run-time decomposition, privacysensitive in the sense agents do not have to disclose their full behaviour.
