The prerequisites are also solved: the construction item's project schedule is made through network planning technology and database's programming; the listing of the materials is memorized according to the construction act; the up_to_date storage information can be gained by contacting to the storehouse's management department in time. Finally, the material request plan is drafted by the method of MRP.
