Policy Modification in Flexible Agent

In order to solve software complexity crisis problem, policy-based method and agent-based system is combined to build autonomic computing system, where agent stands for autonomic element and policy stands for administrator's goal. Due to dynamic nature of administrator's goal, a mechanism must be provided to commit policy modification. This paper proposes an integrative framework where policy modification is considered. Firstly, we provide some postulates for policy modification; secondly, policy modification operators are proposed according to relevant postulates; finally, case study shows the achievement of policy modification in flexible agent.
