Abstract

Abstract: Intelligent agents are powerful tools for complex and dynamic problems. Belief Desire Intension (BDI) is one of the most popular agent architectures for reactive goal directed agents. Planning is intrinsic for intelligent behaviour. But planning from first principle is costly in terms of computation time and resources. BDI agents retain their reactive property by avoiding planning from real-time planning by using predefined plan library designed by agent designers. BDI agents look for a plan in the library to achieve their goals. If the agent could find a plan it fails to achieve the goal. It would be useful to have some real-time look ahead planning capability within BDI framework. In this paper we have proposed an architecture that includes (re) planning in BDI agents. The proposed architecture describes how to integrate a real-time planner with replanning capability in the current BDI architecture. Replanning capability is important for reactive behaviour.
