Since there exists a multi-level policy making system in the market
economies, choices of decision makers at different levels should be
considered explicitly in the formulation of sectoral plans and policies.
To support the hypothesis, a theoretical energy planning approach is
developed within the framework of the theory of economic policy
planning, policy systems analysis and multi-level programming. The
Parametric Programming Search Algorithm has been developed. On the basis
of this theoretical model, an Australian Energy Policy System
Optimisation Model (AEPSOM) has been developed and is used to formulate
an Australian multi-level energy plan.
