Feeder Line Synchronization

In manufacturing environments where many types of items are produced, the total amount for different configurations of a product may not be sufficient to support a Kanban replenishment system. Oracle Flow Manufacturing resolves this situation by enabling you to create schedules for lines that are directly derived from parent assembly line schedules. These feeder lines use sequence information from the parent assembly schedules so that you can synchronize the higher and sub-assembly material with production.

The feeder line synchronization program calculates the date and time the subassembly is delivered to the particular line operation. This date is then be used as the completion date for the subassembly line. The completion date of the feeder line flow schedule is calculated as the difference between the parent assembly's scheduled completion date and the sum of the operation times. This is the sum of the operation times from the consuming operation to the end of the parent line.

Note: The basis type of the subassembly is considered in the calculation. See: Fixed Component Usage

The start time for the subassembly is calculated by subtracting the lead time from the completion date and time. Lead time is obtained from fixed lead time and variable lead time on the organization item. This allows you to synchronize subassembly lines to deliver product exactly when needed by the main line.

You cannot create new synchronized schedules if corresponding schedules already exist on the feeder line. You also cannot re-synchronize rolled schedules. This eliminates potentially creating over production of the subassembly.

Prerequisites

Create flow routings and routing networks for both the parent and subassembly items.
Define the operation sequence for the subassembly on the bill of material of the parent item. This must be equal to the event sequence on the parent routing of the event consuming the subassembly.
Define the variable lead time on the organization item master for each item to equal the TAKT time of each line, respectively.
Define the fixed lead time on the organization item master for each item to equal the total product cycle time (TPCT) or the TAKT time of the line multiplied by the number of operations along the longest primary path of the line.
Define the maximum hourly rate on the line definition for both the parent and feeder line the same as the standard daily running rate for each line, respectively.

To create flow schedules that synchronize feeder lines with parent assembly lines

Navigate to the Feeder Line Synchronization window.

The Parameters window appears.
Select a parent line or range of Lines From and To.
Select a range of Dates From and To.

This is the date range of the start dates of the parent assembly schedule; it is used to determine which parent schedules are synchronized.
Choose OK.
