Casual Dependency Graph into Redesign Goal Tree

  • Make initial redesign goal tree
    • Uses dependency graph and qualitative differential equations
    • Augments each node in causal dependency graph with action increase or decrease
    • For each alternative, a subgoal is created
    • The leaves of the goal tree correspond to externally controlled quantities
  • Goal Pruning : Heuristics
    • prune-violated-constraints
    • prune-weak-thermal-connection
    • prune-undefined-solution
  • Goal Ordering : Heuristic
    • prefer-most-conductive-connection
