Abstract: A supply chain management apparatus which allows determination of the number of orders in accordance with actual demand in a supply chain, and enables a smooth and immediate change in order/production/supply even when the actual demand varies. The supply chain management apparatus creates finished product demand forecast information based on actual sales information provided by a distributor terminal apparatus, creates part demand forecast information from the finished product demand forecast information, provides this for a part manufacturer side apparatus, creates finished product delivery schedule information based on part delivery schedule information provided by the part provider side apparatus, and provides the finished produce delivery schedule information for the distributor terminal apparatus. Said distributor terminal apparatus enables making of a modification request for the finished product demand forecast information after it receives the demand forecast information.

Abstract: In a code data edit apparatus, dot code data read by an optical read unit is input to a processing function unit. In the processing function unit, the dot code data is decoded, and the processing result is displayed on a screen display unit. Upon reception of an instruction and data from a change input unit, the dot code data is edited in the processing function unit, and this process is displayed on the screen display unit in real time. The edit result is output by an edit output unit. In a dot code data writing-once apparatus, a data information determination unit is connected to the output stage of a dot code data read unit through a decoding unit. A display unit is connected to the output stage of the data information determination unit. The data information determination unit is connected to the output stage of a data input unit for inputting writing-once data.
