Identifying critical operations of a production process
First Claim
1. A method of identifying an operation that is critical to meeting a due date of a production order, the method comprising:
- identifying operations associated with the production order;
obtaining schedules for the operations using infinite production planning;
obtaining start intervals for the operations based on the schedules;
selecting a target operation from the operations; and
determining whether the target operation is critical to meeting the due date based on whether the target operation can be scheduled, using finite production planning, in a start interval obtained for the target operation.

Abstract
Identifying an operation that is critical to meeting a due date of a production order includes identifying operations associated with the production order, obtaining schedules for the operations using infinite production planning, obtaining start intervals for the operations based on the schedules, selecting a target operation from the operations, and determining whether the target operation is critical to meeting the due date based on whether the target operation can be scheduled, using finite production planning, in a start interval obtained for the target operation.

17. A computer program product tangibly embodied in an information carrier for identifying an operation that is critical to meeting a due date of a production order, the computer program product comprising instructions that cause a machine to:
-
identify operations associated with the production order;
obtain schedules for the operations using infinite production planning;
obtain start intervals for the operations based on the schedules;
select a target operation from the operations; and
determine whether the target operation is critical to meeting the due date based on whether the target operation can be scheduled, using finite production planning, in a start interval obtained for the target operation. - View Dependent Claims (18, 19)

20. A system comprising:
-
memory that stores executable instructions to for use in identifying an operation that is critical to meeting a due date of a production order; and
one or more processing devices that execute the executable instructions to;
identify operations associated with the production order;
obtain schedules for the operations using infinite production planning;
obtain start intervals for the operations based on the schedules;
select a target operation from the operations; and
determine whether the target operation is critical to meeting the due date based on whether the target operation can be scheduled, using finite production planning, in a start interval obtained for the target operation.
