  • Patent number: 12254478
    Abstract: A delivery date answering apparatus includes: an order quota calculation and disclosure unit for calculating surplus inventory of a product in a demand forecast channel, which is a sales channel where order quantities are forecasted, using the actual inventory and a sales plan of the demand forecast channel, and transfer the surplus inventory to an orderable quota for a non-demand forecast channel, which is a sales channel where order quantities are not forecasted, and set a predetermined disclosed quota for the orderable quota; and an actual order acquisition and delivery date answering unit for determining whether the quantity of an actual order acquired in the non-demand forecast channel is within a range of the disclosed quota. When the order is within the range, answer a date when the actual order is deliverable. When the order is not within the range, answer the order is undeliverable.

  • Patent number: 8494893
    Abstract: A production plan enabling suppression of occurrence of excess stock is made. A shipping request representing the requested amount of shipping for each shipping request week is received. Among the shipping weeks of the shipping requests, the furthest future shipping request week is handled as the furthest future shipping week, and the amounts of shipping of shipping weeks near the present time are determined sequentially from the amount of shipping of the furthest future shipping week.

Among the shipping weeks of the shipping requests, the furthest future shipping request week is handled as the furthest future shipping week, and the amounts of shipping of shipping weeks near the present time are determined sequentially from the amount of shipping of the furthest future shipping week. For the shipping requests after the shipping week n for which the amount of shipping is to be set, the order setting time which is the time of period till the products are delivered to the shipping destination is determined. The allocation order, 1, 2, . . . is determined for each of the shipping requests of the unset shipping so that the longer the order setting time is, the higher the order of allocating shipping request is.

  • Patent number: 6302941
    Abstract: A method for producing a molten iron in a blast furnace comprises the steps of: preparing an optical fiber covered with a metallic tube; measuring a temperature of the molten iron flow discharged from a tap hole of the blast furnace by means of making use of a metallic tube covered by the optical fiber to obtain an information of the temperature of the molten iron; and controlling a heat conditions of the blast furnace, based on the obtained information of the temperature of the molten iron. Controlling a heat conditions is achieved by using a heat conditions estimation model, and by inferring a level and a transition of the heat conditions in the furnace.
