Recently, many engineers establish sub-system performance target. However crash safety performance target is not run to satisfy rather than other performance. The major cause is stochastic problem. Several crash assessments show lots of result even though under same condition. In this paper, we consider material and steel panel thickness scatter for robustness design using optiSLang. Base on LS-DYNA crash analysis, several design of crash box are built by FCM. As result of this paper process, the characteristic of crash box is founded and then robust-design of crash box is possible considering stochastic behavior.
