This is the key issue in the research for abstractions, models, technologies and methodologies for the engineering of complex systems This is the issue of coordination models and languages [Papadopoulos and Arbab, , Busi et al. MotivationsEvolution of Coordination Models IOrigins of coordination models and languages Coordination models originated in the context of closed and parallel systems E.
How did this happen? In this lecture, I will sketch an explanation and provide a perspective—based on [Omicini and Viroli, ]A. Tuple-based Models for Complex Systems CoordinationOrigins of Tuple-based Models IIFrom closed to open systems Linda introduces an environment abstraction devoted to the management of the agent interaction space As a conceptual consequence, computation and coordination conceived as the management of interaction [Wegner, ] were to be considered as two orthogonal dimensions of computer-based systems [Gelernter and Carriero, ] handled — that is, analysed, modelled, designed, programmed — in an independent way, by adopting suitable abstractions and mechanismsA.
Tuple-based Models for Complex Systems CoordinationEssential Features of Linda-derived Models ITwo other features characterise tuple-based models as they descend fromthe original Linda ancestor distribution of the coordination abstractions expressiveness of the coordination abstractionsrespectively termed as [Busi et al.

Nature-inspired Coordination ModelsNature-inspired Coordination Models INature-inspired computing The main idea is to extract models and patterns from natural systems of any sorts, and apply them within computational contexts Nature-inspired models includes neural networks, genetic algorithms, swarm intelligence,. Coordination in Self-organising SystemsFeatures of Self-organising CoordinationRequired features of self-organising coordination modelsAccording to [Viroli et al.
Coordination in Self-organising SystemsTime-dependency, Probabilistic Behaviour IClassical coordination models Apparently classical coordination models apparently address the issues of time-dependency and probabilistic behaviour in some way For instance tuple matching templates are returned in a non-deterministic way chemical laws are known to be probabilistic and time-dependentA. Coordination middleware — in particular, tuple-based ones — should be adopted to support self-organising semantic coordination Examples eternally adaptive service ecosystems for pervasive computing [Viroli and Zambonelli, ] e-Health systems [Nardini et al.

Abstract Coordination is one of those words: it appears in most science and social fields, in politics, warfare, and it is even the subject of sports talks. AHRQ is funding research to better understand how diagnostic errors happen and what can be done to prevent them.
