Abstract: Different researchers have designed a diversity of model building methods with specific characteristics depending on various data sources, objectives and applications in the system dynamics. On one hand, the expansion of system dynamics applications has caused the development of various model building methods necessary. On the other hand, information technology advances specifically web 2.0 has led to the development of various model building methods with more capabilities. Thus, the main purpose of this paper is to introduce crowd model building based on web 2.0. To achieve this objective, first, various system dynamics modelling methods including document model building (DMB), individual model building (IMB), group model building (GMB), community model building (CoMB) and crowd model building (CMB) were compared and contrasted through a systematic literature review. Finally, crowd model building was fully explained.
