Coordinating Tasks in Agent Organizations

چکیده
One of the main issues in agent organizations is the specification of coordination mechanisms between agents playing roles in a regulated social environment. Both in Organizational Theory as in MAS, the concept of role plays an important role in the specification of coordination. We present a role-based model for organizations that integrates both views. Role hierarchies define the links through which one role can exercise power over, or otherwise influence, other roles. This means that a role can demand the realization of a goal from another role, or request goals from another role. In organizational contexts this can also mean that the responsibility of some tasks lays with the role in the top of the hierarchy. Role dependencies indicate how the goals of different roles depend on each other, and how interaction is to be achieved. Each role dependency indicates a need for coordination between those roles. The way interaction is to be organized between the roles, depends on the organizational power structures between the roles. In this paper, we discuss the implications of the coordination type to the dependencies between roles. Given that one role depends on another to achieve a goal, the realization of that goal depends on the social relationship between the roles, that is, whether the role has power over the other role. We distinguish between hierarchical, network and market social relationships between roles.

Coordinating Agents in Organizations Using Social Commitments
One of the main challenges faced by the multi-agent community is to ensure the coordination of autonomous agents in open heterogeneous multi-agent systems. In order to coordinate their behaviour, the agents should be able to interact with each other. Social commitments have been used in recent years as an answer to the challenges of enabling heterogeneous agents to communicate and interact succ...

Enabling Agility through Coordinating Temporally Constrained Planning Agents
In crisis response, hierarchical organizations are being replaced by dynamic assemblies of autonomous agents that promise more agility. However, these autonomous agents might cause a decrease in effectiveness when individually constructed plans for moderately-coupled tasks are not jointly feasible. Existing coordination techniques can be applied in the pre-planning phase to guarantee feasible j...
متن کاملCoordinating Autonomous Planners
We present a framework for coordinating autonomous planning agents. Together, these agents have to achieve a set of interdependent (elementary) tasks. Each of the agents receives a unique subset of tasks to achieve, but an agent may be dependent on other agents completing (some of) their tasks first. Each of the agents needs to make a plan in order to achieve its set of subtasks. Task dependenc...
متن کاملCoordinating Workflows in Shared Grid Environments
Computational grids are characterized by widely distributed computational resources shared by virtual organizations. Users submit workflows of tasks to be executed, some of which may duplicated because of their shared application domain. The problem of allocating tasks to resources in grids has unique characteristics, governed by three features. First, users are generally interested in workflow...
