Forward Schedule Block Operations in Sequence

Explanation

Use this activity to forward schedule shop order operations connected to an operation block in sequence after each others from a given start date/time.

Prerequisites

• An operation block in status Planned, Released or Started with one or several connected operations must exist.
• The site should not use constraint based scheduling server.

System Effects

• The Schedule Direction for the operations connected to the operation block will be set to Forward Scheduling and scheduled sequentially of each others with the first operation starting on the start date/time provided in the dialog box. Operations within the block will be ordered following below priority:

1. Operation Priority.
2. Operation original Planned Start Date/Time.

• As a result of this activity the Schedule Direction for the operations connected to the operation block will be set to Forward Scheduling and scheduled sequentially of each others with the first operation starting on the start date/time provided in the dialog box. Operations within the block will be prioritized according to their original planned start date/time.
• Operations parallel to, and succeeding the rescheduled operations will also be set to Forward Scheduling and rescheduled.
• If the Compress Operations check box is selected and the new date/time for the rescheduled operation is later than the original date/time, operations on the same shop order preceding the rescheduled operation will be set to Backwards Scheduling and rescheduled with a Finish Date adjacent to the rescheduled operations new Start Date.
• If the Schedule with new Setup Time between Operations check box is selected, all operations except the first one will be scheduled with a new setup time as defined in the Setup Time field. The Scheduled Setup Time field will be updated with the new setup time.
