  • Topics addressed
  • Organisation-centric point of view How to design
    / learn, instantiate and evolve complex org.
    structures ?
  • Agent-centric point of view How to act alone /
    as part of a team within complex org. structures?

Autonomic Electronic Institutions
Overview
  • Introduction Aims and scope
  • Activities
  • Planning

6
Introduction
  • Research issue How to endow an agent
    organisation or institution with autonomic
    capabilities to yield a dynamical answer to
    changing circumstances through the adaptation of
    its norms.
  • An autonomic computing system must configure
    and reconfigure itself under varying (and even
    unpredictable) conditions. System configuration
    or "setup" must occur automatically, as well as
    dynamic adjustments to that configuration to best
    handle changing environments.

7

    self-configuration

    circumstances

What is agreement planning?
Planning by negotiation or Negotiation by
planning?
1. Planning is the problem, negotiation is the
technique (new planning framework)2.
Negotiation is the problem, planning is the
method (traditional view of planning for solving
a particular problem)
14
Planning decisions agreements
  • Which (actions different alternatives)
  • When (temporal allocation of actions)
  • How (resources)
  • And also
  • Negotiation cycle planning execution
  • Time to reach the agreements (planning time)
  • .

15
Where planning meets negotiation?
PLANNING NEGOTIATION
AGENTS Single-agent Multiple planning entities (humans, soft agents, ) Collaborative framework Distributed planning Multi-agent planning
KNOWLEDGE Perfect knowledge Global knowledge/Partial knowledge Sharable / Private / Hidden Distributed planning
GOALS Joint goals Joint goals ? collaborative work, joint negotiation for a common global purpose Independent goals ? collaborative work, individual negotiation for individual interests Single-agent goal ? collaborative work (??) Independent goals ? collaborative individual work (do ones own thing)
OPTIMIZATION Time, resources Negotiation elements

Task 3.3
Deliberative Agreement

Task 3.3. Deliberative Agreement social choice
and collective judgment models for open MAS
Objectives. The overall goal of this task is to
analyze properties and develop mechanisms for
collective decision making in human and
artificial agents. The emphasis will be on tasks
that require complex agreements, i.e. involving
at least one of the following (i) argumentation
processes for deliberation, (ii) aggregation of
sets of interconnected judgments or (iii)
organizational division of labour.
Technologies. This goal requires the integration
of relevant contributions in social choice
theory, argumentation models, aggregation
procedures, organizational and institutional
models.
19
Task 3.3. Deliberative Agreement social choice
and collective judgment models for open MAS
Focus while social choice models typically focus
on aggregating individual preferences, we will
focus on judgment aggregation. Judgment
aggregation is new field that aims at finding
collective judgments on logically interconnected
propositions.
Year 1
Requirement Analysis Study of relevant aspects
in social choice theory, argumentation models,
aggregation procedures, and organizational and
institutional models.

Task 3.3. Deliberative Agreement social choice
and collective judgment models for open MAS
Any group that attempts to manage a common
resource (e.g., aquifers, judicial systems,
pastures) for optimal sustainable production must
solve a set of problems in order to create
institutions for collective action.
As an example of application, we consider the
management of a common resource, namely the
aquifers of a region, and the joint decision is
whether or not a shortage of water for
consumption is likely (e.g. to implement a ruling
that changed the normal exploitation regime to a
restricted exploitation regime)
