This abstract discusses work looking into techniques for improving the quality of the search heuristics used to guide forward-chaining planning. The improvements in heuristic quality are made by performing a static analysis of the planning problem to identify commonly occurring 'generic types', and providing additional heuristic guidance based on their known properties. In doing so, the heuristic is tailored to the identified properties of the domain and can provide a more realistic heuristic value and refined relaxed plan. This can potentially lead to reduction in the time taken to find a plan, and the generation of shorter plans.
