PROBLEM TO BE SOLVED: To correct an inventory plan at an early stage and to maintain proper inventory by comparing prearranged inventory with real inventory, deciding whether or not their difference is within a set reference range and outputting correction alarm of an inventory plan when it is outside the range. SOLUTION: An input device 2012 inputs an item number (S101). Item prearranged inventory, real inventory and a reference error range are retrieved from a storage device 2014 (S102). When the difference between the prearranged inventory and the real inventory is not within the reference error range (S103), the real inventory is compared with reference inventory range and when it is not within a reference range (S104), an output device 2013 outputs correction alarm of an inventory plan (S105). The device 2012 inputs correction will of the inventory plan (S106). When the correction will exists (S107), a correction item of the inventory plan is inputted from the device 2012 (S108). The correction item of the inventory plan is stored in the device 2014 (S109). |
