The advantage of multiple allocation policies is that it helps the planner in communicat-ing the plan preferences of the user to the scheduler. For example, the end user may prefer plans with lower number of actions in the plan at the cost of increased plan length. Poli-cies also make sense computationally. The complexity of the CSP problem increases with the domain size of its variables since it is O(k n ) where there are n variables with average domain size of k. The idea of having multiple allocation policies is useful in guiding the scheduler towards easier resource allocation problems first.
