Definition

Determines whether the Component Maintenance Cockpit (CMC) uses proportional or progressive distribution of the total buffer among the operations in an order.

You can use a compressed or a non-compressed view of the operations in an order.

In the compressed view the CMC bundles sequential operations from the same work center and displays them in one line. In determining buffer distribution when using the compressed view the CMC determines the position of each work center in the order, the duration of total consecutive operations in the work center, the defined stretch factor, and the total number of work centers in the order.

In a non-compressed view each operation is displayed in a separate line in the CMC. In determining buffer distribution when using the non-compressed view, the CMC determines the position of each operation in the order, the duration of each operation in the order, the defined stretch factor, and the total number of operations in an order.

Procedure

Each time rescheduling is performed the CMC recalculates the buffer available for an order and distributes it among the operations in that order:

  • Leave blank or enter 0 to use proportional distribution, thereby distributing the total buffer proportionally among all operations in an order. In this case the buffer duration for each operation is proportional to the operation duration, where operations that last longer receiving more buffer, and short operations receiving less buffer.
  • Enter a value greater than 0 to use progressive distribution, thereby distributing the total buffer progressively among all operations in an order. In this case the buffer duration for each operation is consecutively longer, as the later operations in the chain receive a greater amount of buffer.

For further information and examples, see the SAP Library (Help => Application Help).

Examples

Progressive or Proportional Distribution - Non-Compressed View

  1. For each operation, standard duration + ((operation position number -1) x stretch factor)
  2. (Number of operations in order x (number of operations - 1)) x stretch factor
  3. 50% of point 2 + total work duration
  4. Total Available Buffer per Operation = Point 1 x Total Buffer / Point 3

Progressive or Proportional Distribution - Compressed View

  1. For each work center Standard duration of consecutive operations per work center + ((work center position number -1) x stretch factor)
  2. (Number of work centers in order x (number of work centers - 1)) x stretch factor
  3. 50% of point 2 + total work duration
  4. Total Available Buffer per Work Center= Point 1 x Total Buffer / Point 3
