As the scale and scope of distributed and multi-agent systems grow, it
becomes increasingly important to design and manage the manner in
which the participants interact. The potential for bottlenecks,
intractably large sets of coordination partners, and shared bounded
resources can make individual and high-level goals difficult to
achieve. To address these problems, many large systems employ an
additional layer of structuring, known as an organizational design,
that assigns agents particular and different roles, responsibilities
and peers. These additional constraints can allow agents to operate
effectively within a large-scale system, with little or no sacrifice
in utility. Different designs applied to the same problem will have
different performance characteristics, therefore it is important to
understand and model the behavior of candidate designs.
In this talk I will first introduce a domain-independent
organizational design representation able to model and predict the
quantitative performance characteristics of agent organizations. This representation, capable of capturing a wide range of
multi-agent characteristics in a single, succint model, will support
the selection of an appropriate design given a particular
operational context. I will demonstrate the representational
capabilities and efficacy of this language by comparing a range of
metrics predicted by the models to previously obtained empirical
results. I will then outline how these same models can help design
agent organizations, through the application of appropriate search
techniques over the modeled space.
