Background: Priority Dispatch Report

Use the Priority Dispatch Report (MPD) program to establish a priority list (in highest-to-lowest priority sequence) of manufacturing orders for work centers and print the Priority Dispatch Report. See Road Map for work flow.

Prioritization Methods

You select one of these prioritization methods as a Program option:

  • Critical Ratio Calculation                                                     

This method calculates a critical ratio factor for each manufacturing order that is processed. The critical ratio applies to the completion of the manufacturing order not just the operation.

The critical ratio factor is established by dividing the hours from the current date to the order due date by remaining hours required to complete the order. The remaining available hours are calculated from the beginning of the next full day until the exact end of the order's remaining work and then adding, if available, the order's management priority.

The smaller the critical ratio, the higher the order's priority. If the critical ratio is negative, the operation is past due.        

  • Management Priority

This method lists each work center's manufacturing orders in highest to lowest priority sequence, using the management priority assigned to a manufacturing order with the Manufacturing Order Maintenance (MIM) or Order Release Selection (MRR) program.

  • Operation Start Date

This method uses release order requirements, such as the order quantity, the work center's factored machine capacity (setup, run, and move days), and the send ahead quantity from each of the order's operation sequences to determine a start date for each operation. The operations are then listed in priority sequence from earliest to latest start date for each work center.    

  • Operation Priority

This method calculates an altered critical ratio factor for each operation that is processed. The ratio is established by dividing the time available at the work center of the operation by the time required to complete the operation.

Note
The ratio applies to the operation and not to the order. The remaining available hours are calculated from the beginning of the next full day until the exact end of the operation's remaining work and then adding, if available, the order's management priority.  The smaller the priority ratio is, the higher the operation's priority.  If an operation has a negative priority, it is past due.                                                                               

Priority Dispatch Report

The report includes this data:

  • Sort type: Method selected for the Prioritization method Program option

  • Date selected for the Select current date Program option

  • Department number

  • Work center

  • Machine number

  • Description of the operation performed at this work center

  • Number of shifts at this work center

  • Labor capacity in hours at this work center

  • Machine capacity in hours at this work center

For each manufacturing order operation:

  • Customer number if this order is linked to a sales order

  • Parent item number on the manufacturing order

  • Manufacturing order number

  • Quantity ordered

  • Pieces that remain to be built

  • Start date for operation

  • Date the manufacturing order was release

  • Due date for the manufacturing order

  • Routing operation sequence

  • Routing operation code

  • Hours remaining to be worked:

For regular or unattended operation: (Qty remaining x Hours per piece) + ((Quantity remaining / Standard lot size) x Setup time)

For batch operations: ((Qty remaining x Hours per batch) / Pieces per batch) + ((Qty remaining / Pieces per batch) x Setup time)

  • Calculated priority, which is based on the prioritization method you selected

  • Management priority from the Mgmt priority field in the Manufacturing Order Maintenance (MIM) program

  • Operation code in process at this time

  • Total hours remaining to be worked

If you selected the Print routing information? Program options, the report includes:

  • Operation code for the previous operation in the sequence

  • The department that is responsible for the work center for the previous operation in the sequence

  • Work center for the previous operation in the sequence

  • Machine number for the previous operation in the sequence

  • Operation code for the next operation in the sequence

  • Department that is responsible for the work center for the next operation in the sequence

  • Work center for the next operation in the sequence

  • Machine number for the next operation in the sequence

  • Tool number

If you selected the Print item's inventory quantities? Program option, the report includes:

  • Entry in the Xref field in the item's record in the Enterprise Item Maintenance (IM) program

  • Quantity on hand

  • Quantity obligated

  • Quantity on order
