Publication number: 20050235133Abstract: Slips each having a unique number are inputted and retained in an input queue. Slips of the number corresponding to the multiplicity level of the business-related processing are taken out in the order of older input from the slips retained in the input queue to assign management numbers to the slips, after which a consolidated-format slip is produced by consolidating the slips taken out. During the multiple processing, the consolidated-format slip is divided into single slips, business-related processes of the number corresponding to the multiplicity level are executed in parallel and the slips processed are consolidated and delivered to the next multiple process. When all of the multiple processes have been completed, the consolidated-format slip obtained as the result of processing is divided into slips (single slips) and outputted in the order of their input.Type: ApplicationFiled: August 31, 2004Publication date: October 20, 2005Inventors: Yoshiyuki Terai, Isamu Kawamura, Yoshihiro Hirano
