The Agent Factory Framework

• Deployment Process– Defines how to deploy a multi-agent system– Starts with an informal specification– Identifies platform configurations & the distribution of the initial agent community

The Agent Factory Framework

• Development Kits– Provide support for developing specific types of

agent– Minimum requirement is a agent architecture / interpreter– The most mature is the AFAPL Development Kit

AFAPL

• AFAPL: Agent Factory Agent Programming Language– High-level language for specifying agent behaviours based on multi-modal

logic of commitment• Beliefs: The current state of the world• Plans: Possible courses of action that the agent may follow• Commitments: The courses of action that the agent has decided to follow• Commitment Rules: Situations in which new commitments should be adopted

– Combined with a set of Java-based agent components• Perceptors: generate beliefs about the current state of the environment• Actuators: implement the primitive actions of the agent• Modules: Private internal resources that the agent can use to store data

– Plus support for reuse through a C-style #include mechanism
