Patent number: 8290608Abstract: The present teaching is intended to observe the delivery date of a product and decrease the number of workpieces in a merger process. A treatment sequence calculator included in manufacturing instruction equipment identifies an in-process part being worked in each process, and calculates the delivery-date allowance of the in-process part. In-process parts whose delivery-date allowances fall below a predetermined threshold are inputted to each process in ascending order of delivery-date allowances. In-process parts whose delivery-date allowances are equal to or larger than the predetermined threshold are inputted to each process in ascending order by a minimum value of remaining treatment times which the in-process parts take to reach the merger process.Type: GrantFiled: July 29, 2010Date of Patent: October 16, 2012Assignee: Hitachi, Ltd.Inventors: Takahiro Nakano, Yoichi Nonaka, Hisaya Ishibashi, Satoshi Nagahara
