Information processing apparatus and method and information processing program recording medium
First Claim
1. An agent system in which a plurality of agents operate over a distributed node network, comprising:
- a platform on one node of the network, on which a plurality of fields of activity and a set of knowledge that are divided into a plurality of knowledge of subsets are provided;
an agent generation unit configured to generate an agent in response to a request;
a planning unit configured to generate a plan that satisfies the request for the agent;
a determination unit configured to determine a reliability of a communication line when an uncertain knowledge is used to generate the plan by the planning unit, wherein the uncertain knowledge is processed by other nodes;
a selection unit configured to select one of a processing of a movement of the agent and a processing based on a contract net protocol in accordance with the reliability;
an execution unit configured to execute the plan after the processing of the uncertain knowledge by the other nodes; and
a field management unit configured to manage the plurality of fields of activity wherein the field management unit assigns one of the plurality of fields of activity to the agent, and assigns one of the plurality of knowledge subsets used for generating the plan by the planning unit, to the agent.

Abstract
A planning means generates a plan to be executed by agents on a node. In the case where the plan generated uses an uncertain knowledge required to be processed in other nodes, a judging means judges the communication line connecting the node and a network is low or high in reliability. In the case where the reliability of the communication line is low, an agent management unit moves the agent for executing the plan to another node for processing the uncertain knowledge. In the case where the reliability of the communication line is high, on the other hand, a cooperation protocol realization means requests an agent on another node to process the uncertain knowledge. An agent execution means executes the plan generated.
