In the production site of the unit basics reinforcing rod for houses, the lead time from order to delivery of products is very short. Therefore the cutting operation of the reinforcing bar is performed every order to carry out a correct and quick activity. However, this operation rule has a low risk of the picking mistake, but on the other hand, it has a problem becoming high in a loss rate by the outbreak of edge materials. In this study, we formulate it as the issue of the bin-packing problem. And the new cutting rule considering multi orders is proposed, and it is inspected about the decrease of the edge materials loss by cutting.
