Method and a system for executing a scheduled production process

摘要

A method and a system execute a scheduled production process having an execution duration within a production schedule executed by a manufacturing execution system. The method includes defining within the production process a resource required for the execution of the production process and defining for the resource a sequence-dependent setup sub-process having a setup duration, a productive sub-process and a sequence-dependent teardown sub-process. The production process is scheduled with a start-time. At a predetermined period at the start-time of the production process, the production process for dispatching and subsequent executing is confirmed. In response to the confirmation, individual production processes are created for the sequence-dependent setup sub-process, the production sub-process and the teardown sub-process. The created individual production processes are linked together by precedence constraints defining a sequence of the created individual production processes. The production schedule is rescheduled through replacing the production process by the created individual production processes.

1. A method for executing a scheduled production process having an execution duration within a production schedule executed and controlled by a manufacturing execution system, which comprises the steps of:
defining within the scheduled production process a resource required for an execution of the scheduled production process; defining for the resource a sequence-dependent setup sub-process having a setup duration, a productive sub-process having a production duration and a sequence-dependent teardown sub-process having a teardown duration; scheduling the scheduled production process for its execution with a start-time on the production schedule wherein an execution duration is a sum of the setup duration, the production duration and the teardown duration; confirming the scheduled production process for dispatching and subsequent executing at a predetermined period one of prior to the scheduled production process and at the start-time of the scheduled production process; in response to a confirmation of the schedule production process for dispatching, creating individual production processes for the sequence-dependent setup sub-process, the production sub-process and the teardown sub-process, whereby the individual production processes created are linked together by precedence constraints defining a sequence of the individual production processes created; re-scheduling a production schedule through replacing the scheduled production process by the individual production processes created; and executing a re-scheduled production schedule by dispatching the individual production processes created in the scheduled sequence.
