Method and a system for executing a scheduled production process

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.

2. The method according to claim 1 , wherein a duration of 0 seconds is allowed to be assigned to at least one of a setup duration range and a teardown duration range.

3. The method according to claim 1 , which further comprises determining at least one of the setup duration and the teardown duration in dependency of a preceding production process and a subsequent production process respectively.

4. The method according to claim 1 , which further comprises defining within the sub-processes respective resource specific for each of the sub-processes and required for the execution of the sub-processes.

5. The method according to claim 4 , which further comprises defining the resources allocated to the sub-processes in dependency of at least one of a preceding production process and a subsequent production process.

6. A system for executing a scheduled production process having an execution duration within a production schedule executed and controlled by a manufacturing execution system, the system comprising:

a production planner module enabled to define within the scheduled production process a resource required for an execution of the scheduled production process;

said production planner module further enabled to define 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;

a production scheduler module enabled to schedule the scheduled production process for its execution with a start-time on a production schedule wherein the execution duration is a sum of the setup duration, the production duration and the teardown duration;

a production execution module enabled to confirm 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;

said production planner module further enabled to create in response to a confirmation of the scheduled production process for dispatching, individual production processes for the sequence-dependent setup sub-process, the production sub-process and the teardown sub-process, whereby created individual production processes are linked together by precedence constraints defining a sequence of the created individual production processes;

said production scheduler module further enabled to re-schedule a production schedule through replacing the scheduled production process by the created individual production processes; and

said production execution module further enabled to execute a re-scheduled production schedule by dispatching the created individual production processes in a scheduled sequence.

7. The system according to claim 6 , wherein a duration of 0 seconds is allowed to be assigned to at least one of a setup duration range and a teardown duration range.

8. The system according to claim 6 , wherein at least one of the setup duration and the teardown duration is determined in dependency of a preceding production process and a subsequent production process respectively.

9. The system according to claim 6 , wherein said production planner module defines within the sub-processes a respective resource specific for each of the sub-processes and required for the execution of the sub-processes.

10. The system according to claim 9 , wherein resources allocated to the sub-processes are defined in dependency of at least one of a preceding production process and a subsequent production process.
