Validity in modeling systems depends on experiences of designers because validation processes have not been established. The authors propose a noise-adaptive system modeling procedure using a concept of Design Review Based on Failure Mode (DRBFM) as the validation process. The proposed procedure involves,1 Detecting a difference by comparison between a design condition in an ideal model with that in practical one, 2 Setting Noise Ni caused by the difference, 3 Predicting an effect by the noise εi, 4 Inserting an additional element m(εi) in the model and 5 Checking whether other εi, might exist. An experiment of modeling a robust model of a drain tube by university students using the proposed procedure or a normal process (FMEA) was conducted. Mean score of robustness of drains in a group using the proposed procedure was higher than that in the group using FMEA, which demonstrates the effectiveness of the proposed procedure.
