Exceptions and Accountability for Robust Applications of JaCaMo

We present two extensions to the JaCaMo framework that support the realization of robust multi-agent organizations. Robustness amounts to the degree to which a system can function correctly in the presence of perturbations. The first extension provides an exception handling mechanism suited for MAS; the second one is grounded on the notion of accountability to create feedback chains among agents. Both extensions are built upon a uniform approach and provide high-level abstractions that facilitate the design and development of MAS that meet robustness requirements.
