A Fuzzy Multiple Objective Decision Making Methodology for Electricity Generation Planning

Although conventional energy resources are widely used for electricity generation globally as well as in Turkey, the renewable energy resources that do not deteriorate environmental quality and economic efficiency are increasingly favored to meet the energy demands in a sustainable way. Alternatively, limitations on land availability and high initial investment costs impede the development of renewable energy resources. This paper proposes a decision model based on fuzzy multiple objective programming for electricity generation planning in Turkey. Conflicting objectives with their corresponding importance degrees are taken into account to improve the quality of decision making process. Linguistic variables are employed to represent the qualitative data concerning energy alternatives and the importance degree of each objective. The proposed methodology enables to illustrate the trade-off between economic, environmental, social, and political factors in energy planning.
