Summary

We propose the construction of a general-purpose heterogeneous rational multi-agent architecture, and the development --on a computational implementation of this architecture-- of prototype multi-agent systems with learning capabilities that cooperate in the solution of complex problems in medical environments. This proposal involves four working-hypothesis:
  1. Complex rational behaviour, in a software agent, is the result of the cohesive interaction of basic "rationality aspects" (ontological, epistemic, motivational, communicational), each one of them has a formal representation, basic units are assembled through simple, well-defined means, and a rational software agent always has elements that are context-specific.
  2. Those formalizations can be computationally transcribed in an Object-Oriented environment --where available logic-based tools can be adapted and encapsulated-- to build general purpose rational agents that can be tailored to act efficiently in a given context.
  3. The deployment of rational general-purpose accountable software agents, that can be tailored to cooperatively solve different tasks, is a viable, effective and economically sound way of addressing some of the challenges brought forward by real world complex applications.
  4. The medical and hospital-management environments constitute appropriate "proof of concept" cases for multi-agent based tools; from a technical standpoint, because of the complexity and richness of the problems involved, and from a technology-transference perspective, because of the technological maturity of these environments.
Distinctive features of this proposal are:
  • Formal: the use of a layered reflective first-order framework, based on a reflective dynamic logic, that integrates into a cohesive architecture various "aspects of rationality", which, in turn, are themselves formal systems.
  • Technical: (i) the "encapsulation", in an object-oriented environment, of the computational counterparts of the layered reflective structure. (ii) Cooperative problem solving through multiagent systems with federated learning capabilities.
  • Technology Transfer: An industry-assessed "proof of concept" in five real-world test problems of considerable economic significance in the medical and hospital-management environments.
