Some subtypes for Problem_Solving_Task


    (Note: The '%' before a type means that it has more than one supertype).


  % Problem_Solving_Task  --   PST (a process such as the ones modelled in knowledge acquisition), e.g. a diagnostic
          Real_life_PST  --  a problem solving task which is composed of more basic problem solving task
               % KADS_Real_life_PST  --  combination and refinement of basic PSTs for modelling a real life task
                        Knowledge_engineering_with_KADS

        % KADS_Primitive_Task  --   e.g. Generalize, Specify, Compare, Modify
        % KADS_basic_PST  --  a basic (or generic) task which may be a component of a real life PST
