4 Juan Antonio Rodríguez Aguilar (IIIA) Autonomic Electronic Institutions Task 3.1

5 Autonomic Electronic Institutions Introduction: Aims and scope Activities Planning Overview

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 Introduction Example: Supply chain automation

8 Activities Negotiation models and strategies for self- configuration –Flexible negotiation models to reach agreements on the fly to respond to new goals Connections: –Task 3.5 in WP3 –Input: Techniques from WP2 and WP4 –Output: eProcurement demonstrator in WP8 Background: Work at IIIA on supply chain formation Current team: Jesús Cerquides, Jar

11 Eva Onaindia (UPV) Agreement Planning Task 3.2

12 Task 3.2 Agreement planning WP3: Organisations (Leader: Sascha Ossowski – URJC) Task 3.1. Autonomic Electronic Institutions.) Task 3.2: Agreement Planning (DESIGN, ORGANIZATION, MODEL) Task 3.3. Deliberative Agreement: social choice and collective judgment models for open MAS Task 3.4 3D Electronic Institutions (3DEI) Task 3.5: Mechanisms for Efficient Organisational Teamwork WP4: Argumentation and negotiation (Leader: Lluís Godo – IIIA) Task 4.1. Agreement Logics Task 4.2. Real-Time agreements Task 4.3. CBR-based Mediating Agent Task 4.4 Planning and scheduling capabilities for an agent (SOLVING TECHNIQUES, COMPUTATION) Task 4.5 Agreement management with Data Mining

13 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? PLANNINGNEGOTIATION AGENTS Single-agentMultiple planning entities (humans, soft agents, …) Collaborative framework Distributed planning Multi-agent planning KNOWLEDGE Perfect knowledgeGlobal knowledge/Partial knowledge Sharable / Private / Hidden Distributed planning GOALS Joint goalsJoint 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 one’s own thing) OPTIMIZATION Time, resourcesNegotiation elements

16 Task 3.2: Workplan Project report: –D3.2.1: Group planning agreements M36 Our proposal: Study the relation between planning and negotiation –M8: Analysis and identification of components Agents, Knowledge, Goals, Optimization Survey –M12: Discussion with “negotiation” people Planning needs introduced by negotiation Planning agreements between agents

17 Enric Plaza (IIIA) Deliberative Agreement Task 3.3

18 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 Deliverable D3.3.1 Requirement analysis for deliberative agreement. Month 12 Requirement Analysis: Study of relevant aspects in social choice theory, argumentation models, aggregation procedures, and organizational and institutional models. Year 1 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. Aggregation procedures for interconnected judgments.Month 24 Deliberation and aggregation for interconnected judgments.Month 40 Institutional models for deliberative agreementMonth 54 Years 2-5

20 Task 3.3. Deliberative Agreement: social choice and collective judgment models for open MAS 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) 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.

21 Task 3.3. Deliberative Agreement: social choice and collective judgment models for open MAS Interconnected causal judgments.
