Table 1. Features of the raw material inventory problem in Baosteel

	Too many categories of raw materials are stored in the depots
	The demand for the products is relatively stable
	The demand for each raw material is large and relatively stable
	The lead time needed for replenishment is relatively long
	OOS is not allowable
