And it is a pressing need to establish the method of performance optimization by observing the operation situation and improving the resource allocation method adaptively. As a method which meets this demand, we propose the Policy Hierarchy Method. This method enables a complex scheduler to combine two or more scheduling algorithms, and to be constructed systematically. The Policy Hierarchy Framework was developed based on the proposal method, and was applied to the construction of a storage system. The effectiveness of the Policy Hierarchy Method was confirmed by evaluating this system.
