Second, we make a taxonomic analysis of energy policy formulation problems, learning from the literature. System dynamics is one such tool. Since system dynamics is a behavior-oriented simulation discipline, sensitivity of behavior pattern measures, such as equilibrium level or oscillation amplitude to the model parameters should be evaluated in order to explore the effects of parameter uncertainty on the behavior patterns. The system dynamics (SD) approach was used as both the methodology and tool for modelling and simulation in this book. The DSM concept offers the following advantages [18]: (i) its matrix format gives a concise, visual, and intuitive representation of dependencies among system elements; (ii) the matrix-based.
