In the early design process, diverse design ideas must be obtained from global solution search under the constraint of unclear design conditions. Because it is difficult to apply the conventional engineering design in the early design process, the emergent design method is proposed as a design method that can be applied in the early design process by a conventional research. Moreover, the emergent design system that can generate diverse three dimensional forms is proposed as an application of the emergent design method. To obtain diverse design solutions, this system should appropriately set the parameters with the application case. However, it cannot judge whether the value of the obtained parameters are the best because the parameters are decided by trial and error. In this research, the parameters that influences the diversity of form was extracted, and it aimed to show the knowledge of extracted parameter for the diversity of generated form and the setting method of these parameters. Therefore, the parameter of this system was assumed to be a factor, and an analysis of variance was conducted, and the parameters, which influence the diversity of generated form, were extracted. Moreover, it was analyzed to clarify the relationship to the diversity of form and extracted parameters, and the conditions about these parameters setting were shown.
