Using the knowledge
gained through the previous section, selected energy modeling tools were reviewed to assess for comparative analysis, and to identify the characteristics of energy models. Energy models are developed using theoretical and analytical methods of several disciplines, including engineering, econo- metrics, operations research, and computer sciences. This paper limits a survey to renowned energy models in the literature and models that have been applied for Thailand. These models vary widely in their approaches, methodologies, data requirements, and outputs. Therefore, the evaluation procedures are consisted of two stages. In the first stage, the criteria for inclusion of models in the evaluation are following:
