Specify Scheduling Settings for Scheduling Server

Explanation

Use this activity to define the different default time frames and other settings used by the Scheduling Server. You must also define how the scheduling server should assign load to the different resources. This mandatory task is to be performed by a system administrator or equivalent person.

By specifying a transport calendar you can exclude non-working days when calculating the transport time. The transportation calendar takes effect only when shop order operations are scheduled and when the preceding operation or operations have a defined transportation time.

Prerequisites

There needs to be a valid connection between the Constraint Based Scheduling (CBS) site and the Scheduling Server.

System Effects

As a result of this activity the values you specify are used by the Scheduling Server to schedule operations.

Procedure

1. Open the Scheduling Basic Data window.
2. Populate the window or query for the site.
3. In the Site field, select the site for which to define the default values.
4. Click the Shop Order Scheduling/Scheduling Server tab. In the Host and Port fields in the Communication Settings area, specify the host (the IP address is preferred over the host name) and port (usually four digits) to be used for the Shop Order Scheduling Server.
5. In the Scheduling Horizon (Days) field, enter the number of days the Scheduling Server should use. This is the time period that will be considered when constructing the schedule. Any operations that cannot be included within this horizon will not be scheduled. The default value is 365. The shorter the time frame the faster the scheduling process.
6. In the Scheduling Startpoint (Hrs from Present Time) field, enter a default start time for the first operation in the schedule. This value is optional, with the default value of zero.
7. In the Priority Adjustment Factor Weight field, enter a value to indicate the weight used for prioritization of shop orders. The default value is 1.
8. In the Transport Calendar field, enter the calendar or select a suitable calendar from the List of Values. This calendar will be used to calculate the scheduled transport time. When scheduling a shop order operation, the scheduled transport time will be used. 
   Note: If you want to view the transport calendar, click Settings in the Scheduling Server and select Schedule Settings. The Schedule Settings dialog box opens. To view transport calendar details, double-click on the transport calendar object. To get a graphical representation of the transport calendar, drag the transport calendar object to the left of the Gantt chart.
   To view the scheduled transport time of a single shop order operation, right-click on the shop order operation object and click Show. The Operations dialog box opens. Click the Show Contents tab.
9. In the Sequencing Horizon (Days) field, enter number of days. This is the value the system uses to specify default start and end dates in the Sequencing Assistant. The default value is zero.
10. In the Setup Optimization section, select one of the three options to determine what factors the scheduling server will use to optimize setup.
11. In the Adjust Schedule area, select the Allow Past Due Load in Adjust Schedule check box, if you want to keep preceding operations of each of the reported/scrapped operations in the same operation structures in the past when the Adjust Schedule logic is executed. When the check box is not selected, the preceding operations of each of the reported/scrapped operations in the same operation structures will be scheduled from current time.
12. In the Scheduling Server tab, select the Extend Shop Order check box in the Action When Lot Size is Modified on Shop Order area, if you want shop orders to be expanded or contracted according to changes to their scheduled time requirement. This will be done without changing the current start time of the modified shop orders. Note: However in the following situations, the scheduled start time is changed;
    • If the expanded SO is scheduled in the past before expanding.
    • If the expanded SO affects a promised SO and cannot be scheduled before it.
13. In the Action When Buffered Operation Reporting is Enabled area, select the Adjust Schedule Due To Shop Floor Reporting check box if you want the schedule to be adjusted to reflect time reported on shop order operations. You can use the options under this check box to indicate how you want the schedule to be updated.

• Prioritize Reported Operation - at the next execution of buffered operations reporting, the reported operation is given priority and scheduled as close as possible to now time.
• Keep Scheduled Operation Sequence - the schedule will be updated according to shop floor reporting at the next execution of buffered operations reporting, but without altering the previous schedule sequence. Subsequent operations in the same order structure will move closer to the reported operation in order to fill any capacity gaps which occur immediately after the reported operation.

13. Save the record.
