RECOVERY SERVICES FOR THE PLANNING LAYER OF AGENTS

Khaled Nagi, George Beskales

Abstract

Software agents represent aim at automating user tasks. A central task of an agent is planning to achieve its goals. Unexpected disturbances occurring in the agent execution environment represent a serious challenge for agent planning. In this work, a recovery model for the planning process of agents is proposed to cope with disturbances caused by system failures; which often lead to system crashes. The proposed recovery model supports the Hierarchical Task Networks (HTN) planners which represent a broad family of planners that are widely used in agent systems. A prototype for the proposed recovery services is implemented to demonstrate the feasibility of the proposed approach. Furthermore, a simulation is built and many simulation experiments were conducted to gain insight about the performance of the proposed recovery model.
