Software Agents in the IMPACT System
The IMPACT (Interactive Maryland Platform for Agents Collaborating Together) is an ongoing joint project (with Univ. Maryland and others) to provide a system for creating and deploying software agents, which control local data and knowledge bases. The agents may communicate, and collaborate to solve complex tasks. Software agent architectures are emerging as a design paradigm for distributed hetereogeneous data access.
Practical applications of IMPACT include e.g. supply chain management, the aircraft control flight into terrain (CFIT) problem (Lockheed, Boeing), and department store applications.
The system is based on the following design principles and components:
- incorporation of legacy code and data
- service description language (SDL) for agent services
- matchmaking for best-fitting services
- IMPACT Servers for yellow pages services
- intelligent agent decision making
- secure reasoning
- temporal reasoning
- uncertain reasoning
- meta-reasoning and belief
