Abstract
The facility layout problem has been studied by a lot of researchers. Most of the researchers have formulated the layout planning problem as a minimization problem of the transportation distance and the transportation cost. In the formulations, production demand is assumed to be constant. Therefore, re-planning and change of facility layout are required when the production demand has changed. This is unacceptable when such demand change occr frequently. This research considers planning of a robust facility layout against the demand change, and reports the result of formulation of the layout planning as an optimization of the sensitivity for the demand change.
